PreFormed Slopes are designed to create the UPC required slope under a waterproofing membrane. Slopes allow you to easily install the pan liner and mortar bed in one day. They’re easy to cut, allow the mortar bed to drain properly and saves time by eliminating sloped mortar bed that goes under pan liner. Slopes are 2′ x 4′ and are sloped from 3/4″ to 1/4″ to ensure proper drainage.
