Why Kids Need Safe Jumping Platforms for Above Ground Pools

An above ground pool jumping platform provides a safe, designated area for kids to jump into the water, but it requires careful planning to prevent serious injuries. Here’s what you need to know before building or buying one:

Quick Safety Guidelines:

• Minimum water depth: 8 feet for any jumping platform (12 feet for commercial installations)
• Never allow diving: 7-foot depth is NOT sufficient for diving from any height
• Best options for above ground pools:
  • Cantilevered deck platforms (built into pool deck structure)
  • Portable inflatable water trampolines (requires 8+ ft depth, 2,200 lb anchoring)
  • Pool entry steps with non-slip surfaces (shallow water only)
• Critical safety features: Non-slip surfaces, independent structural support (never attach directly to pool walls), proper anchoring systems

Key Risk: According to industry standards, jumping platforms create significant liability if not designed with appropriate water depth and structural integrity. DIY platforms must never stress the pool shell, coping, or bond beam.

The good news? You can create fun, safe jumping experiences for kids without expensive commercial equipment—if you understand the engineering basics and follow strict safety protocols.

I’m Bill Dudley, and over my 47 years working on pool projects across North America, I’ve seen both brilliant and disastrous above ground pool jumping platform designs. In this guide, I’ll show you exactly how to build or choose platforms that prioritize safety while maximizing backyard fun.

Understanding the Above Ground Pool Jumping Platform

When we talk about an above ground pool jumping platform, we aren’t talking about the springy diving boards you see at the Olympics. In residential pools, a jumping platform is typically a rigid structure designed for feet-first entry into the water.

The biggest difference between platforms for inground pools and those for above ground pools is the structural support. Inground pools have a concrete bond beam that can handle the torque of a diving board. Above ground pools, however, rely on thin steel or resin walls and a vinyl liner. These walls are designed to hold the outward pressure of water, not the downward or lateral force of a 150-pound teenager launching themselves into the air.

Rigid Platforms vs. Flexible Boards

For above ground pools, we almost always recommend rigid platforms over flexible boards. Flexible boards create “spring,” which multiplies the force exerted on the mounting point. If that mounting point is your pool’s top rail (coping), you are asking for a structural failure. According to the Safe use of Diving Boards, Platforms and Starting Blocks standards, rigid platforms are much more predictable and safer for residential recreational use.

The Importance of Structural Integrity

The pool’s wall thickness and coping strength are not sufficient to support a jumping platform. If you drill into the coping to mount a post, you risk cracking the resin or bending the steel, which can lead to a liner leak or a total wall collapse. At Affordable Pool Inc., we’ve seen DIY projects in Boston and Nashua where homeowners tried to bolt platforms to the pool frame, only to find their pool “lopsided” by the end of the summer. The platform must be completely independent of the pool structure.

Critical Safety Requirements for Jumping and Diving

Safety isn’t just a suggestion; it’s a mathematical requirement based on physics. Before you even think about design, you must measure your water depth.

The 8-Foot Rule

The absolute minimum depth for jumping from any raised platform is 8 feet. While many above ground pools are only 48 to 52 inches deep (about 4 feet), some specialized “deep end” above ground pools exist. If your pool is a standard 4-foot depth, a jumping platform is technically unsafe for anything other than a controlled “step-in.”

Statistics and Standards

• 7 Feet is Not Enough: Research shows that 7 feet is not deep enough to safely dive. Even for jumping, a 7-foot depth carries a high risk of “bottoming out” if the jumper is heavy or enters the water with high velocity.
• Commercial Standards: For those looking at high-end jump towers, the Supertramp 23 specifications and other commercial-grade jumping products require a minimum of 8 to 12 feet of water depth to prevent spinal injuries.
• NSPI Guidelines: The National Spa and Pool Institute (NSPI) standards mandate that any pool with a diving board must have a “diving envelope”—a specific shape of the pool floor that ensures the diver never hits the slopes or the bottom.

DIY Design Ideas for an Above Ground Pool Jumping Platform

If you have a pool deck, you have the perfect foundation for a jumping area. The key is to design the jumping zone as a “cantilevered” section of the deck. This means the platform hangs over the pool water without actually touching the pool wall or coping.

Essential DIY Safety Features

When designing your platform, keep these features at the top of your list:

1. Non-Slip Textures: Use “Aqua-Plast” style coatings or grip tape. Wet wood or plastic is a slip hazard.
2. Weight Capacity: Ensure the structure can handle at least 600 lbs of dynamic load (the force of someone jumping, not just standing).
3. Smooth Edges: Sand down every corner. A child slipping off the edge shouldn’t encounter a sharp wooden corner or a jagged screw head.

Building a Cantilevered Above Ground Pool Jumping Platform

To build a safe cantilevered platform, follow these steps:

1. Post Placement: Set your 4×4 or 6×6 pressure-treated posts at least 3 feet back from the pool wall.
2. Concrete Footings: In New England areas like Bedford, NH or Andover, MA, you must bury your footings below the frost line (usually 36-48 inches) to prevent the platform from shifting during the winter.
3. X-Bracing: Use diagonal bracing between your posts. This prevents the platform from swaying side-to-side when a kid runs toward the edge.
4. Joist Hangers: Use heavy-duty galvanized joist hangers to connect your frame. Do not rely on “toenailing” screws, which can pull out under the stress of jumping.
5. Decking Screws: Use stainless steel or high-quality coated screws to prevent rust from the pool chemicals.

Portable and Inflatable Above Ground Pool Jumping Platform Alternatives

If you don’t want to build a permanent wooden structure, there are excellent portable options.

• Inflatable Water Trampolines: Products like the Supertramp 17 are fantastic for larger above ground pools with deep centers. The Supertramp 17 details indicate it requires 8 feet of water depth.
• Swim Steps and Teaching Platforms: For shallower pools, a “teaching platform” like the IPU SSPI10 can provide a stable place for kids to stand and “hop” into the water. These are usually weighted down with sand or water and have non-slip surfaces.
• Weight and Anchoring: If you use an inflatable, you need a serious anchoring system. A 2,200 lb anchor weight (often a heavy bag of gravel or a concrete block on the pool floor) is required to keep the platform from drifting and hitting the pool walls.

How to Install and Anchor Your Platform Safely

Stability is the difference between a fun afternoon and a trip to the emergency room.

Ground Stability and Footings

Never place a jumping platform on bare soil or “deck blocks” sitting on top of the grass. The vibration from jumping will eventually cause the blocks to sink or tilt. We recommend pouring concrete footings. If you are in a coastal area like Hampton, NH or Rye, NH, the sandy soil may require even deeper footings to reach stable ground.

Protecting the Pool Liner

One of the biggest mistakes we see is homeowners allowing the platform to rub against the pool’s top rail. Over time, the vibration will wear through the vinyl liner. Always maintain a 1-2 inch gap between your platform and the pool coping. You can fill this gap with a soft pool noodle or foam buffer that is not attached to the pool, providing a “soft landing” for toes without transferring weight to the pool frame.

Hardware and Corrosion

Pool water—especially salt-water systems—is incredibly corrosive. Always use hot-dipped galvanized or 304 stainless steel hardware. Be aware of www.P65Warnings.ca.gov regarding certain chemicals in treated wood or PVC materials; always wash your hands after construction and ensure the materials are rated for contact with swimming water.

Risks, Liability, and Long-Term Maintenance

Adding an above ground pool jumping platform changes your home’s risk profile.

Insurance and Liability

In the eyes of an insurance company, a jumping platform or diving board is an “attractive nuisance.” Before you build, call your agent. Some policies in Massachusetts or New Hampshire may be voided if you install an unengineered jumping structure. To mitigate this, ensure your platform is behind a locked pool gate and that you have “No Diving” signs clearly posted.

Annual Inspections

Wood rots and bolts loosen. Every spring, we recommend a “shake test.” Stand on the platform and try to rock it. If it moves more than a fraction of an inch, your bracing or footings have failed. Check for:

• Rust: Look for “bleeding” around bolt heads.
• Splinters: Sand the wood and re-apply a non-slip sealer.
• Liner Wear: Ensure the pool wall hasn’t bowed under the platform.

Frequently Asked Questions about Pool Jumping Platforms

Is 7 feet deep enough for a jumping platform?

Technically, 7 feet is deep enough for a “cannonball” where the jumper stays tucked, but it is not safe for straight-body jumps or diving. At 7 feet, the risk of hitting the bottom is high for adults or older children. For maximum safety and to avoid liability, we recommend an 8-foot minimum.

Can I attach a platform directly to the pool wall?

No. Above ground pool walls are not load-bearing in that direction. Attaching a platform directly to the wall will cause the wall to crimp or the coping to crack. The platform must be supported by posts that go into the ground outside the pool.

How do I prevent damage to my pool liner?

The best way to protect your liner is to ensure no part of the jumping platform touches the pool. If you use an inflatable platform inside the pool, use a “liner pad” or a piece of scrap vinyl underneath the anchor points to prevent the weight from chafing the floor of the pool.

Conclusion

Building an above ground pool jumping platform is a great way to turn your backyard into the neighborhood’s favorite hangout spot. However, the line between “fun” and “hazardous” is thin. By following the 8-foot depth rule, using independent cantilevered supports, and choosing non-slip materials, you can ensure your kids stay safe while they splash.

Pool finishes contribute greatly to the overall look of a swimming pool as the color of the water can easily be influenced by the pool interior. Polished aggregate pool finishes incorporate the use of fine pieces of colored stones, which include granite, marble and quartz. This kind of finish is quickly becoming more popular than the traditional pool plaster in places like Newmarket, New Hampshire. This guide will help you better understand the properties of polished aggregate pool interiors so that you can make an informed decision about your swimming pool design.

• The aggregate mixture consists of white or colored traditional plaster mixed with a variety of small pieces of stones. They provide a much more luxurious pool surface as compared to traditional pool plasters.
• The aggregate needs to be mixed proportionately to achieve a particular color and then it has to be applied manually by using a trowel. Once the aggregate is applied to the pool shell, the surface is polished to make it smooth and to ensure that the colors of the stones are visible.
• The surface provided by polished aggregate pool finishes is hard and it does not readily react with chemicals. This gives the surface a degree of resistance against stains and aging damage.
• Due to the many different types of stones that can be used, aggregate finishes come with a very large variety of colors and textures. Multiple types of stones can be combined to form a particular shade, giving each pool owner the freedom to choose the exact shade that they need.
• The addition of stone-pieces extends the life of the plaster to about fifteen years. It works well with classic designs of swimming pools due to the effect it has on the color of the water.
• As the surface is polished and smooth, it provides good grip underwater. Since the grip is not compromised, it makes it a safe mixture to be used for pool coping.

With time, plaster aggregates will see the signs of aging with the appearance of cracks and non-uniformity on the surface. Such issues need to be addressed quickly as they might prove to become a safety hazard to you and your family members. Ensure that you use a professional pool renovation or pool repair service as they would be able to repair every aspect of your pool and keep it in a usable condition for a longer period of time.

The pool coping and finish has a huge influence on the design of a swimming pool. A good swimming pool finish would be able to provide good friction under wet conditions, make the swimming pool look great and require low maintenance. Exposed aggregate pool interiors are very low cost and versatile compared to other options like pool tiles, and they also offer better performance than traditional pool plasters. This guide will help you gain more knowledge about exposed aggregate pool interiors if you plan to use it for your pool.

• Exposed aggregate finish involves the use of a concrete base mixed with colored pebbles, stones and even glass beads. The variety you get is mostly because of the innumerable combinations of different colored stones.
• As the pieces of stones and pebbles come to the surface once the concrete sets, the surface would not be very smooth, but it would provide superior grip in wet conditions. Smaller pieces of stones make the walking area more comfortable without compromising on the friction.
• It offers a lifespan of around fifteen to twenty years as the materials in the aggregate do not break down as easily as the ones found in traditional pool plaster. The recent trends of pool owners in Raymond, New Hampshire, choosing to opt for the aggregate pool finish over traditional pool plasters is because of the former’s superior performance.
• You can get a range of textures according to the kind of ingredients used and the approximate size of each piece in the mixture. Either way, they need to be applied and handled by trained professionals as the mixture needs to be spread evenly across the surface, without allowing the formation of air bubbles.
• The colors shown by the surface changes with the depth of water. This can be used to make the the pool look more dramatic as the shallow areas would have a slightly different color than the deep areas.

Once the exposed aggregate mixture is applied around the pool, the surface would need to be power washed with a solution of muriatic acid to reveal the pebbles under the top layer of concrete. For swimming pool renovation, make sure that you use the help of a professional as these processes require a degree of knowledge and skill acquired through experience. Even if there are any repairs that need to be done, a professional would be able to do a clean job without damaging any other part of your swimming pool.

Swimming pool owners around areas like Hampton, New Hampshire are increasingly moving towards choosing stone pool tiles for their swimming pool design. Such pool tiles can have a variety of natural stones as the main source, including marble, granite, onyx, limestone and slate. If you are considering using stone pool tiles for your swimming pool, this guide will help you with your decision.

• Stone pool tiles are best used when you want the swimming pool to blend in perfectly with its natural surroundings. The designs which are created by stone pool tiles complement a modern architecture. The natural look that stone gives to the pool make it look more like a pond, and the dark colors accents the depth of the water.
• Stone pool tiles are very long lasting and they require little maintenance. There is no question of rust or any such reactions due to constant contact with water and they are able to withstand all weather conditions perfectly.
• During installation of stone pool tiles, make sure that they are treated so that they do not absorb water, as some materials have a tendency to hold water. The tiles would need to be retreated once every few years so that your pool remains functional.
• The textures provided by stone tiles also come in a large variety. You may have smooth surfaces or slightly rugged surfaces to suit your design. Either way, ensure that the tiles are not slippery when they come in contact with water.
• Stone tiles are much heavier than most other options of pool coping, so you might need to consider the total weight of installing such tiles in your entire pool especially if you have an indoor pool.
• The tiles are very strong and they can withstand a great deal of pressure. However, there are still chances of tiles chipping or cracking due to overuse as they age.

In the case of any problems related to stone pool tiles, make sure that you call a pool repair professional as they would have the necessary tools and knowledge to deal with these issues. Proper installation and maintenance of stone tiles would be able to give you many years of service before you face any problem with it. While choosing a stone tile design, ensure that it goes well with the design of the area surrounding the pool as you would be unlikely to make any changes to the pool design for a very long time.

Swimming pools around Exeter, New Hampshire are seeing a new trend of owners choosing to use glass pool tiles for the interior of their pool. Glass pool tiles are very attractive and they come in a very large variety of shapes, sizes, colors and textures. The touch of elegance it adds to the swimming pool makes it stand out more as a work of art. If you are considering choosing glass pool tiles for your swimming pool, this guide will help you better understand what to consider.

• There are many different kinds of glass pool tiles which are available in the market. You can have opaque glass to completely clear and transparent glass tiles, and designs which have varying degrees of translucence. You would need to pick out the color and transparency according to what kind of effect you would want in your swimming pool. More transparent glass tiles keep the pool looking brighter while opaque glasses makes the pool look deeper and more natural.
• Even the shape and size of glass tiles are different. Some glass tiles have a high degree of consistency, which tends to give a clean, formal look to your swimming pool while some glass pool tiles are arranged haphazardly. Large glass pool tiles with clean lines would suit more spacious pools as it gives the swimming pool a touch of elegance while the tiles which have a handmade, rugged texture would go best with smaller swimming pools.
• Due to the large variety of material, size, color and design, glass pool tiles come in a very wide price range. They are generally priced higher than the traditional plaster finish, but there are many affordable ones which may suit your designing requirements. While choosing a glass pool tile, make sure that you take the time to see the different types which are available so that you would find the best fit.
• The installation and repair costs of glass tiles are higher than traditional pool finishes as it requires much more skill. However, glass tiles are also very durable and they do not react easily with pool chemicals. This gives them a long lifespan.

Sometimes, glass tiles may get cracked or broken due to the changes in temperature or due to water pressure. If this is the case, make sure that you call a professional who specializes swimming pool repair. Glass tiles require special skill as the tiles are smooth so creating an underwater bond which works perfectly is essential.

The interior of a pool has a huge effect on the look and feel of the swimming pool. Whether you plan to construct an in-ground pool or renovate an existing pool, a good interior finish will not only provide comfort to the swimmer’s feet, but would also be stylish and durable. There are many different pool finishes available in Derry, which gives you a great variety of options while you are deciding the design of your swimming pool. Pool tiles are one of the most expensive types of pool finishes, but it provides the most durable and long lasting service. This guide will help you decide the pool tile finishes which will best fit to your needs.

The advantages

Pool tiles offer a wide variety of colorful design options. There are also many different shapes and sizes that you can choose from and the material of the pool tile will decide its cost, durability and aesthetic. Most of the tiles have a glossy finish, which augments the water’s reflective properties making the pool look very glamorous. The many different combinations that are possible with type of material, shape and color of the tile, you can be assured that the design of your pool would be truly unique. Also, it is the most durable finish available. If applied properly and maintained, they would never need replacement.

The disadvantages

The cost of this finish is the main deterrent, as it is more expensive than aggregate and plaster finishes. Even the time which is required to install pool tiles is much longer as compared to other interior finishes. Although pool tiles are very strong and durable, any cracks or breakage created with age would mean that the tile must be replaced. The repair and replacement procedure is complicated and time consuming, and it is best left to professionals.

The signs of damage

Pool tiles may be cracked, lose or they may come off altogether. This can happen due to the changing temperatures that the pool sees which causes expansion and contraction of the tiles. This problem can be mitigated by using fillers which adapt to the changes in temperature. If your pool tiles need repair, ensure that you call a professional as the procedure needs to be done carefully in order to not damage the rest of the pool. Also, make sure that you get the damaged tile repaired as soon as possible to reduce the risk of accidents.

Traditional pool plasters are a mixture of cement and marble. It is white in color and smooth to touch, and it has been in use since more than half a century. Most swimming pools throughout the US, including the ones in Londonderry, use the traditional pool plaster which has a light, shimmering blue color, but pool owners see many problems with these plasters.

Traditional pool plasters are porous and they react with harsh pool chemicals. They are more susceptible to permanent stains and etching marks which can occur with time. Traditional pool plasters may require lesser investment at the beginning, but the amount of care and maintenance required to preserve this material has made it unpopular amongst pool owners in recent times.

The advent of higher quality pool resurfacing material

Despite being almost twice as costly compared to traditional surfaces, pool pebble plaster is one of the most popular choices of modern pool surfaces that pool owners use. The material used by this pool plaster includes a specially crafted cement formula infused with pebble aggregates. Compared to traditional marble-based plasters, the pool pebble plasters are much more resistant to stains and scratches. These plasters come in a very wide variety and are differentiated in terms of smoothness of the surface and color.

Better endurance and safety

Pool pebble plasters do not react readily with harsh pool chemicals, which dramatically reduce the cost of maintenance. The life span is much greater compared to traditional plasters. The surface of pebble plasters may be different depending upon the amount and type of ingredients used. Standard pool pebble plasters tend to have a slightly rough feel, giving it a superior grip in wet conditions. This improves the safety of pool users, but might trouble sensitive feet. Specially polished pebble plasters can be used if any of your family members have sensitive feet.

Variety of colors

Manufacturers can create a myriad of colors by adding aggregates of specific pebbles or sea shells to the mixture. Swimming pools, especially the ones which have gradual changes in depth tend to look much more beautiful when they use pebble plasters. The colors that these plasters give with shallow water tend to be quite different than the ones they exhibit in deeper water. This happens due to the different colors of pebbles used in the mixture. The colors are impervious to fading and this plaster stands the test of time, making it the most durable type of pool plaster available.

Pool plasters not only provide a good surface for the interior of the swimming pool, but they also have a dramatic effect on the look and design of the pool. The traditional swimming pool plasters are created by a mixture of cement and powdered marble. Such plasters have a white surface which is smooth to touch and it gives the water a shimmering color of blue. But traditional marble based pool plasters are porous, which means that they have a tendency to harbor bacteria and show stains.

Modern, durable plasters

Pool diamond brite plaster is a very popular choice amongst people as it gives one of the best interior finishes to the swimming pool. It has natural quartz as a primary ingredient, which gives it excellent durability. Unlike marble based pool plasters, pool chemicals do not readily react with diamond brite plasters. They are, therefore, resistant to permanent stains and remain unaffected by most of the harshest pool chemicals.

Better safety and more comfort

Pool plasters need to be comfortable to the feet. An extremely smooth surface might get slippery which would become a safety hazard to pool users. Pool diamond brite plaster was crafted to be slip resistant under wet conditions. It is also very comfortable to the pool users, which helps them stay in the water for longer times, extending the hours of entertainment and leisure that they gain from the swimming pool.

Maintenance

Maintaining traditional marble-based swimming pool plasters is a difficult task considering the reaction it has to harsh pool water chemicals. Pool diamond brite plasters are resistant to the etching and stains which can be caused when pool water is treated by harsh chemicals. The plaster can also be drained and cleaned without seeing any damage on the surface. The amount of effort that pool owners need to put in for the maintenance of such plasters is therefore, reduced.

Apart from all these advantages, pool diamond brite plasters come in a variety of different colors, each of which gives the swimming pool water a distinct look. As natural quartz comes in many different colors, it is possible for manufacturers to create mixtures which give the pool water a specific shade, dramatically increasing the amount of customization of your swimming pool. Even though it costs more than traditional plaster, many spas, public swimming pools and private pool owners across Windham have begun using diamond brite plasters for their decorative and practical purposes.

You might have heard of your pool maintenance guy ask you about shock treatments for your pool. Shocking a pool, as it is known, does not involve electricity in any way, it does, however, involve a lot of chemicals ‘shocking’ your pool and cleaning it before it recovers. It is an important part of pool repair. The main ingredient to the shocking process is chlorine.

Super-chlorination as it is also called is the adding of large doses of chlorine directly into the pool’s water, it can be from 5 to 10 times the normal amount used in pools. The main reason behind super-chlorination is to get the pool to maintain a positive level of free chlorine. It is achieved when the excess amounts of the chemical breaks down all the combined chlorine, clearing contamination and destroying organic waste. The process will be repeated till the water can hold free chlorine for a few hours after the treatment.

When to shock a pool

Shocking a pool should be done at the first sign of algae. If you feel a slippery slime like layer over the floor and walls of the pool, or see floating colonies, it has to be done. It is a good idea to go for this treatment right after the year’s rains as well. If there has been a period of heavy usage with a lot of people continually over a few days, or if the water starts to look muddled and dirty, shocking can be done.

As for the frequency of shocking, it depends on the temperature of the region and how often the water is used. If you live in a cool or cold region, once a month is a good idea, pools in warm and hot regions will have to be shocked twice a month, minimum.

One of the biggest advantages to shocking your pool periodically is that you can prevent the development of resistant microorganisms in the water, which is unpleasant and will eventually hike the cost of pool repairs in the future.

Note that it may not be safe to use the pool right after shocking it as chlorine is highly toxic and swimming or ingesting water from pools that have been super-chlorinated is dangerous. Have the maintenance crew check and test the water, wait for their clearance before jumping into it. The safe levels are below 3 ppm, this can take, depending on a number of variables, between 3 and 12 hours.
