ABSTRACT:
A group of modular planar structural foam sections are laid on the ground directly underneath the liner of an above-ground pool. The foam panels are cut so that they fit tightly side-by-side covering all areas within the frame. The joints between the panels are then filled by caulking and taped over to smooth the top surface of the joints. The result is an improved pool underlayment system which provides many advantages, including cushioning of swimmer impact to help prevent shallow diving injuries.
