Our Waterproofing Services
Comprehensive protection designed for long-term performance in every environment.
The Principles That Guide Our Work
At Pro Waterproofing Ltd, we take pride in delivering smart, flexible and affordable waterproofing solutions for every type of project. As manufacturer-approved installers of leading systems, we offer a wide range of high-quality products to ensure the best fit for each application. Our team provides specialist services across Underground Tanking, Decks and Flat Roof Waterproofing and Roof Maintenance and Leak Repairs, giving our customers reliable, long-lasting protection backed by expert workmanship.
Underground Tanking
Pro Waterproofing has extensive hands-on experience in all forms of underground tanking, including water storage areas, swimming pools, under-slab waterproofing, footings, lift wells, commercial precast retaining walls, and planter boxes.
We understand exactly which products and systems suit each situation. With our trained and experienced applicators — and a “do it once, do it right” attitude — we provide reliable, long-lasting protection for any below-ground requirement.
Because underground areas are difficult and costly to repair once construction is complete, choosing the right waterproofing system from the start is critical. Our team offers durable, effective solutions and can recommend alternatives tailored to your project.
Products and systems we use:
- Bentonite Tanking (Volclay): Ideal for wrapping footings and under-slab areas on both residential and commercial projects. Highly resistant to damage during steel installation.
- Swelltite: A composite membrane made of 95% bentonite and 5% Butyl rubber for flexibility and self-sealing performance. Can be installed quickly on damp or wet surfaces.
- Easygum / Sika Blackseal Plus: Bitumen-based waterproofing membranes used for tanking building foundations.
- Torch-On Waterproofing: Thick, reinforced bituminous membranes that provide immediate, watertight performance upon installation.
- Peel-and-Stick Membranes: Fast, efficient self-adhesive options for specific below-ground applications.
Decks & Flat Roofs Waterproofing
Torch-On Waterproofing Systems
Torch-on membranes provide a durable, multi-layer waterproofing solution ideal for decks, flat roofs, warm roofs and gutters. Installed as a double-layer system (approx. 8mm), the top layer offers strong resistance to weathering and excellent UV protection, making it a long-lasting choice for exposed areas. We supply and install torch-on systems from a range of trusted manufacturers to ensure the right fit for your project.
TPO Membrane Waterproofing
TPO (Thermoplastic Polyolefin) is a single-layer UV-resistant membrane available in 1.5mm or 2mm thickness. With heat-welded seams and a full range of compatible accessories, TPO systems deliver superior watertight performance for low-slope and pitched roofs, balconies and gutters. This system is especially recommended for buildings with higher fire-risk, providing a fully warranted, resilient, and long-lasting waterproofing solution for both residential and commercial applications.

Liquid Applied Waterproofing Systems
Liquid-applied membranes cure into a seamless, flexible waterproof layer that bonds directly to the surface. Applied by brush, roller or spray, they easily cover complex details and small cracks, making them a cost-effective option for both new and existing structures.
These systems offer excellent benefits, including a high-gloss finish that increases interior brightness and a hard-wearing, durable surface suitable for continuous pedestrian traffic.
