Although it may seem surprising, traditional membranes often fail even within two or three years from placement on a new construction. Moreover, they have no crack sealing ability. If the concrete beneath the membrane cracks to any significant degree, the membrane will split, tear away from the surface and fail.

The building of CSCC in Phnom Penh suffered from both concrete cracks and failing membranes.

CWS Admix was adopted to permanently end the waterproofing failures at the three basements of the building.
