Cavity Drainage

Proper cavity drainage relies on a cuspated membrane to guide water down to the floor junction to filter out through the perimeter channel. If you need mortar webs, weep tubes, vent boxes, or mesh screen rolls, then MasonryDirect is here to help! Our masonry supply store offers all of the masonry tools and materials needed to get the job done right, all backed by our industry expertise at a price you’ll love.
