GROUND WATER
A wet pit is a health hazard and a major problem. Every precaution needs to be made to prevent water and moisture from seeping into the pit. This includes damp or wet floor and walls that will produce odor, mold, and mildew.
The first step is to establish the wet weather water table. This information may be available from the County Agricultural Stabilization Office. If this information is not obtainable do not take chances. Assume that ground water will be a problem. Test holes in the general area where the pit will be dug, 2' below the bottom of the pit floor. Cover the test hole to prevent surface water (rain) from running into the test hole. Check the ground water level every 10 days.
The second step is to establish the depth of the pit. Resi-Pit/Porta-Pits require 18" to 36" in depth from gym floor to pit floor. The depth of the Resi-Pits lessens the chances of having a water/moisture problem, but does not eliminate the possibility. Deep foam or loose foam pits always require a drainage system.
