Foam wells in 5 steps

Gymnastics and Foam Pit Construction

Step 1

Determine the area needed to perform the intended tricks or maneuvers. Think big for Moto-cross, BMX and Skateboarding as it usually involves more speed and altitude. Length is usually the second most important dimension to consider, always erring on the side of caution. When considering the length of the hole, consider how fast and far it is feasible for the athlete and then extend it slightly to provide a safe cushion. Depth is the most important dimension, as the number of blocks between the landing and the hard surface below is the amount of cushioning or load deflection the pit offers. Generally, a safe depth for gymnastics is 6 to 8 feet. This depth is likely to be sufficient for most skateboarding and BMX applications. Motocross deals with higher speeds, higher height, and more weight, so choosing a pit depth on the back end of the spectrum is even wiser, perhaps. Finally, determining width and siding is important to ensure safety. Consider the possible range of error from left to right and choose a reasonable space to land. Once again, speed and distance affect the chance of error in one direction and must be taken into account.

Step 2

Consider the actual location. Inside? Outside? On the floor? Underground? These are all questions that need to be answered when locating where you plan to build your well. Indoor pits are common for gymnastics, eliminating the worry of rain or snow. Outside pits are common for snowboarding, motocross, and other extreme sports. These wells should probably use waterproof covers or blocks to withstand the elements. The foam obviously acts like a sponge and after rain without a cover a hole will be very wet and if left that way mold is likely to grow. There are often complaints of illness after using a dirty foam pit. Aboveground wells are possible, but still must meet all of the dimensional safety measures described above, especially depth.

Step 3

Calculate the number of blocks needed to fill a well. The math is a simple volume calculation, length * width * height * 0.7 * 8 = # of 6″ blocks or

length * width * height * 0.7 * 8 = # of 8″ blocks. These are industry standard calculations.

Step 4

Select a block density. The higher the density of the blocks, the greater the load deflection or the safer they are for the athlete. Lower density blocks will save money, but may not be as safe.

step 5

Fill your pit, have fun and always practice safely!

Maintenance:

Periodically, holes should be fluffed as the foam will compact with repeated impacts and provide less protection. Shuffling the blocks prevents this from becoming a problem. The blocks should also be replaced periodically with fresh blocks for both cleanliness and safety as the foam is struck.

security warnings

Warning: Even with a quality hole, neck and back injuries can still occur, do your best not to fall on your head or neck to reduce risk, regardless of the hole.

Warning: Landing in the hole in an arched position, especially in a forward position, can hyperextend and injure your back.

Warning: landing on your knees, especially in an arched position in the pit, can cause hyperextension injuries to your back.
