Stop Damp and Water Ingress in Block & Concrete Walls

Block and concrete walls are prone to moisture problems. Efflorescence stains, damp interiors, musty smells, and water seeping through blockwork are all signs your wall is not properly sealed. Standard paints don't solve it - they peel, blister, or trap moisture, often making the problem worse.

At Roof Savers, we apply high-performance elastomeric membranes and protective coating systems that stop water ingress and protect blockwork long-term. We diagnose the problem first, then match the right product to your wall - not a one-size-fits-all approach.

Suitability depends on your wall's condition, the source of the moisture, access to the external face, and whether any cracks are actively moving. We assess each job individually before recommending a coating system.

Waterproofing Block & Concrete Walls With Noxyde

Every wall is different. The coating system we recommend depends on the wall type, exposure, and the source of the moisture problem. We inspect your wall, identify what's causing the issue, and apply the right solution.

Noxyde Elastomeric Membrane

Our primary system for above-ground block and concrete wall waterproofing. Noxyde creates a seamless, flexible, waterproof skin over the entire wall surface. With 200% elasticity, it bridges hairline cracks, resists UV degradation, and prevents future efflorescence or dampness from developing.

Noxyde is best suited for:

  • Exterior block walls exposed to weather and wind-driven rain

  • School and institutional boundary walls

  • Warehouse and factory block partitions

  • Commercial building facades and exterior walls

  • Any above-ground block or concrete wall with recurring damp issues

We are certified Noxyde applicators - meaning we apply the product to manufacturer specifications and can offer the full product warranty.

Fixing Efflorescence on Block Walls

Those white, chalky stains on block walls are mineral salts being pushed to the surface by moisture moving through the wall. Painting over efflorescence doesn't work - the moisture just pushes through again. A proper elastomeric membrane seals the surface and significantly reduces the likelihood of the cycle repeating.

Repairing Damp Interior Walls Caused by Block & Concrete

If the inside of your building feels damp, smells musty, or has visible moisture patches on block walls, the wall is absorbing water from the outside and transferring it through. We seal the exterior face to stop water entering the blockwork in the first place.

Stopping Water Ingress Through Block Walls

Wind-driven rain can force water through mortar joints and porous blocks, especially on exposed elevations. Our coating systems create a continuous waterproof barrier that prevents water penetration while still allowing trapped moisture to escape as vapour.

Fixing Peeling Paint & Failed Coatings on Concrete Walls

If a previous paint or coating has failed on your block wall, it was likely the wrong product for the job. We strip back failed coatings, prepare the surface properly, and apply a system designed to handle the moisture load your wall is dealing with.
