Overview

Mortar bed waterproofing is also referred to as thick bed, full mortar bed or mud bed methods. These methods involve the following procedures:

Use Pro-Slope or dry packed mortar to create a substrate that is sloped 1/4" per foot from the perimeters to the clamping ring drain. Loose lay a waterproofing membrane like Chloraloy over the substrate. Flood test the system to ensure it is watertight. Next, install a mortar bed over the Chloraloy. After the mortar bed cures (generally overnight), tile can be bonded to the mortar bed.
