HII liner pad is specifically engineered to Protect the Pool Liner while giving a soft and comforting pool bottom. Made to resist virtually all soil chemicals while maintaining that soft 'bounce' in the pool, year after year.
Liner pad makes liner installation better because the liner will not be dragging across the top of the sand. When the liner drags across the top of the sand it makes drag marks which creates places for algae to grow. With the liner pad, the liner will simply glide across the pad right into place. Leaving the pool bottom just a smooth as you made it.
