Self adhesive on one side:
Waterguard has a butyl rubber adhesive on one side only and a co-polymer surface on the other. This makes installation much easier as the installer can work on the membrane without getting stuck.

Optional Preformed corners:
Sealed, pre-formed internal and external corners reduce the likelihood of leaks. Eliminating the time consuming process of manually creating corners as with Tilesafe.

Superior waterproofing capabilities:
Tests have proven that Waterguard provides superior waterproofing capabilities to Tilesafe. The test was conducted with a 150mm head of water over a series of weeks. No leak from Waterguard.

Excellent crack bridging properties:
Tests have shown that Waterguard has superior lateral movement (5mm)
absorbtion properties caused by the shifting and drying of floors over time.

Not sensitive to chemicals:
Can be used with epoxy grout and solvent based sealers for stone  tiles - unlike Tilesafe.

Supplied with a butyl sealant:
Part of the pack, so no need for the installer to purchase separately. Can also be used to repair small holes in the membrane, if damaged.

Guide lines for easy measurement:
Pre-printed grid lines provide an accurate guide when trimming the membrane.

Supplied with 150mm wide jointing tape:
Waterguard cannot be overlapped, so a jointing tape is supplied to create a watertight seal at any joints.

    10m sq Impey WaterGuard® Wall Membrane
    500ml BAL primer
    10m jointing tape
