Surface applied, cement based render, waterproofing barrier for positive and negative water pressure applications.
Waterproofing of concrete and masonry structures both new and old. BB75-Z can be used on most masonry surfaces, including sandstone, provided surfaces are adequately prepared. Ideal for application in sewerage environments and for solving the problem of water seepage through concrete and masonry in both new and old structures.
Vandex BB75-Z is ideal in applications where the high pressure face is not easily accessible. It is also ideal for waterproofing the inside face of swimming pools, sewerage processing tanks, concrete block walls and any masonry surface where crystal growth waterproofing will not be effective due to a lack of alkalinity in the substrate.
