Ultimate Protection for Internal Walls, Basements & External Brickwork

Are your walls showing signs of damp? If your plaster feels brittle, powdery, or sounds hollow when tapped, moisture has likely compromised it. Standard plaster simply cannot withstand water ingress. To properly treat the damage and prevent it from returning, a specialist water-resistant render is essential.

Versatile Defence – Basements to Exteriors

At Crystal Damp Proofing & Basements Ltd, we apply a specially formulated sand and cement mix designed to tackle damp in the most challenging environments:

• Essential for underground spaces, our render provides a robust, impenetrable barrier against heavy groundwater pressure and penetrating damp.
• Shields your exterior brickwork and newly installed Damp Proof Courses (DPC) from harsh weather, driving rain, and continuous moisture absorption.
• Replaces “blown” or moisture-damaged plaster, creating a dry, safe surface that is ready for redecoration.

Powered by Wykamol Renderproof™

To guarantee top-tier protection, our rendering system is enhanced with Wykamol Renderproof, an industry-leading, BBA-approved waterproofing additive. This ensures:

• Dramatically reduces water permeability to stop damp in its tracks.
• Blocks harmful residual ground salts from migrating through the wall and ruining your paint or wallpaper.
• While it stops water from entering, the vapour-permeable formula still allows your masonry to breathe and dry out naturally.
