Crystoflex is a Class 2 flexibility, two part waterproofing membrane comprising of a liquid component of selected polymers and a powder component of selected cements, fillers and aggregates.

When mixed together to form a brushable or rollable slurry, it provides a strong, hydrostatic pressure resistant, flexible waterproofing membrane.

Crystoflex was formulated for immersed or ponding situations such as the waterproofing of water tanks and water features but is just as suitable for non-immersed applications such as roofs or under-tile waterproofing.
