ABSTRACT:
A device for improving the drainage through, and structural integrity of, a mortar bed of a shower floor. The device encircles a neck portion of a drain in the shower floor. The device is positioned between the mortar bed and drainage weep holes formed in the drain so that practically any water seepage through the mortar bed must pass through the device before entering the weep holes. The device has a greater porosity than that of the mortar bed and provides a larger drainage surface area of the mortar bed than that of the weep holes alone.
