What is Penetrating Damp?
Penetrating damp occurs when rainwater or external moisture seeps through walls, roofs, or ceilings. It is common in porous sandcrete block walls, cracked renders, and poorly maintained gutters or roofs. It typically appears as dark patches, blistered paint, salt staining, crumbling plaster, or mould on internal and external walls.

Our Solution – StopDamp+ Slurry
Unlike traditional cement-based slurries, StopDamp+ Slurry is a breathable damp proof coating. This advanced formulation penetrates deep into wall pores, creating an invisible barrier that repels water while still allowing walls to release trapped vapour.

How We Treat Penetrating Damp
1. Inspection & Diagnosis – We identify points of water ingress, such as cracks, porous blocks, or faulty drainage.
2. Surface Preparation – Damaged coatings or plaster are removed if necessary, and the wall is cleaned to ensure maximum penetration.
3. Application of StopDamp+ Slurry – The slurry is brush-applied directly to affected wall surfaces. It penetrates the substrate and chemically bonds to form a long-lasting hydrophobic barrier.
4. Finishing – Once cured, walls can be painted with breathable coatings or left natural, ensuring a durable and aesthetic finish.
5. Aftercare Support – We provide guidance on exterior maintenance to keep walls protected for years.

Benefits of StopDamp+ Slurry
*Non-Cementitious – Unlike cement slurries that trap moisture, StopDamp+ remains breathable and flexible.
Deep Penetration – Bonds within wall pores for long-lasting water repellency.
*Salt Resistance – Prevents efflorescence and damage caused by soluble salts.
*Breathable Protection – Keeps rainwater out while allowing interior vapour to escape.
*Durable & Eco-Friendly – Weather-resistant, non-toxic, and environmentally responsible.
