Type A waterproofing using Juta's WPSAM and PD1700 protection board. We firstly prepared the substrate by ensuring all shuttering plugs were removed and any defects made good using a waterproof barrier mortar. A fillet of waterproof mortar was then applied to the wall floor joint. In addition to the self-adhesive waterproof membrane and cuspated protection board, a serviceable land drain wrapped in geotextile was also installed.
