Duram Crystoseal – 20kg

Duram Crystoseal is a cement-based waterproofing slurry containing waterproofing crystals which grow into concrete surfaces to create a waterproof barrier inside the concrete. Crystoseal often saves the day when conventional membranes can no longer be applied. Crystoseal is suitable for waterproofing both the positive and negative sides of the substrate.

Crystoseal is a powder and is mixed with water and can be easily applied as a slurry by roller or brush.

For best results drying should be as slow as practically possible. Post dampening is an advantage.
