Reliable Waterproofing for Concrete Roofs, Slabs & Surfaces

Concrete is strong and durable, but it is also porous and vulnerable to water penetration when left unprotected. Over time, rain, UV exposure, temperature changes and surface movement can lead to cracks, damp, peeling coatings and long-term deterioration.

U-Proof concrete waterproofing products are designed to help seal and protect flat concrete roofs, slabs, walkways, parapet areas and exposed concrete surfaces. With correct surface preparation, reinforcement and application, U-Proof helps create a seamless waterproofing barrier that protects against water ingress and weather-related damage.

Common Concrete Waterproofing Problems U-Proof Helps Solve

Concrete waterproofing problems often begin with cracks, porous surfaces, failed coatings, standing water and weak joints. U-Proof helps seal, reinforce and protect these vulnerable areas with a flexible waterproofing system.

Water Penetration

U-Proof helps create a waterproofing barrier that reduces the risk of water ingress.

Surface Cracks

U-Proof Fibre Filler helps reinforce cracks before the main waterproofing layer is applied.

Failed Coatings

U-Proof Liquid Rubber forms a flexible waterproofing membrane over correctly prepared concrete surfaces.

Standing Water

A seamless waterproofing system helps protect exposed concrete from ongoing moisture exposure.

Damp & Moisture Damage

Correct waterproofing helps protect both the concrete surface and the areas below it.

Joints, Edges & Upstands

U-Proof helps reinforce these detailed areas before coating for improved waterproofing performance.

Suitable Concrete Waterproofing Areas

U-Proof can be used across a range of concrete surfaces and details when the area is correctly cleaned, prepared and reinforced where required.

Flat Concrete Roofs

Waterproof exposed flat concrete roof areas affected by rain, UV exposure and standing water.

Concrete Slabs

Protect concrete slabs from moisture ingress, surface deterioration and weather-related wear.

Walkways & Exposed Surfaces

Seal suitable outdoor concrete surfaces exposed to rain, foot traffic and changing weather.

Parapets & Upstands

Protect wall junctions, raised edges and concrete upstands where water can enter.

Cracks & Surface Repairs

Reinforce cracks, joints and damaged concrete details before applying waterproofing.

Maintenance Projects

Use U-Proof for preventative maintenance, small leak repairs and larger concrete waterproofing projects.

Recommended U-Proof Concrete Waterproofing System

For the best concrete waterproofing result, prepare the surface properly, reinforce vulnerable areas and apply a flexible waterproofing membrane.

  • Step 1Inspect the Concrete Surface

    Check the area for cracks, damp patches, failed coatings, loose material, surface damage and signs of water ingress.

  • Step 2Clean & Prepare

    Remove dust, dirt, grease, loose coatings, unstable material and contaminants so the waterproofing system can bond properly.

  • Step 3Prime Where Required

    Use the correct primer where needed to improve adhesion and prepare the concrete surface for waterproofing.

  • Step 4Reinforce Cracks & Details

    Apply U-Proof Fibre Filler to cracks, joints, wall junctions, parapet edges, upstands and other vulnerable areas.

  • Step 5Apply U-Proof Liquid Rubber

    Apply U-Proof Liquid Rubber over the prepared concrete surface to create a seamless, flexible waterproofing membrane.

  • Step 6Inspect and Maintain

    Allow the system to cure correctly, inspect the finished surface and maintain waterproofed areas regularly for long-term performance.

Concrete Waterproofing FAQs

Find answers to common questions about waterproofing concrete roofs, slabs, cracks, joints and exposed surfaces with U-Proof products.

What is the best way to waterproof concrete?
The best approach is to clean and prepare the concrete surface, repair or reinforce cracks and joints, prime where required and apply a flexible waterproofing membrane such as U-Proof Liquid Rubber.
Can U-Proof be used on concrete roofs?
Yes. U-Proof can be used on suitable concrete roof surfaces when the area is clean, dry, stable and correctly prepared before application.
Does concrete need a primer before waterproofing?
Some concrete surfaces require priming to improve adhesion and long-term waterproofing performance. The correct primer depends on the condition and porosity of the surface.
Can U-Proof help seal cracks in concrete?
Yes. U-Proof Fibre Filler is recommended for reinforcing cracks, joints, upstands and detailed areas before applying the main waterproofing layer.
Can liquid rubber waterproofing be used on flat concrete slabs?
Yes. Liquid rubber waterproofing is suitable for many flat concrete surfaces when correct surface preparation, priming and application steps are followed.
