High quality Damp Proofing products

All forms of damp can cause problems to internal wall finishes and contribute to an unhealthy environment. A permanent damp proofing solution, which combines the correct products to combat the source of the problem, is therefore essential.

Rising Damp & Hygroscopic Damp


Rising damp is when water from the ground rises through the capillaries of brickwork, stonework, or mortar. This results in dampness to the internal wall finishes which can be unsightly, unhealthy, and can also lead to hygroscopic damp, where moisture-attracting (hygroscopic) salts are deposited within the fabric of the walls.

Penetrating Damp


Penetrating damp is the result of water penetrating horizontally from the exterior through the fabric of a wall. It can occur in any building and, as well as lowering the thermal performance of the wall, it can lead to other serious problems such as frost damage.

Treating Damp Problems


Much like the best waterproofing solutions, the best damp proofing solutions use different products in combination to form the most comprehensive defence possible. Appropriate damp proofing products can prevent and control water ingress into a property and protect against the risks of damp walls, condensation, timber decay and wood rot, and structural deterioration.

What damp proofing brands do we stock?

Frequently Asked Questions About Damp Proofing

What is damp proofing, and why is it important?

Damp proofing is a process or treatment applied to building materials or structures to prevent moisture ingress and the associated problems such as mould growth, structural damage, and deterioration of interior finishes. It’s essential for maintaining structural integrity and ensuring a healthy indoor environment.

What are the common causes of dampness in buildings?

Dampness in buildings can result from various sources, including rising damp from groundwater, penetrating damp from leaks or water ingress, condensation from inadequate ventilation, and capillary action from moisture absorption by porous materials.

What are some signs that your building may have a dampness problem?

Signs of dampness in buildings include damp patches or stains on walls or ceilings, peeling paint or wallpaper, musty odours, mould or mildew growth, rotting wood or decayed plaster, and a feeling of dampness or clamminess in the air.

What are some commonly-used damp proofing products and treatments?

Common damp proofing products and treatments include damp proof courses (DPCs), which are horizontal barriers installed in walls to prevent rising damp, damp proof membranes (DPMs), which are moisture-resistant membranes installed beneath concrete slabs or floors, and damp proof paints or coatings applied to surfaces to repel moisture.

Can I apply damp proofing products myself, or do I need to hire a professional?

The application of damp proofing products depends on the complexity of the project and the expertise required. Some products, such as damp proof paints or coatings, may be suitable for DIY application, while others, such as damp proof courses or membranes, may require professional installation for optimal results.
