Gundlach - Positive Weep Hole Protector

The Waterproofing Membranes from Gundlach — quiets footsteps and evens out the subfloor beneath your new floor.

This patented clear plastic drainage disk is for placement around a drain opening in a shower floor. Designed to be positioned between the floor pan and the mortar laid over the floor pan. The ridges of the Positive Weep Hole Protector allow for drainage of water to the weep holes in the drain receptor. Helps prevent water from sitting between the shower pan liner and mortar bed.

The inner and outer diameter of the disk are perforated to allow for customization depending on shower drain size.
