Waterproofing systems

The best leak is the one that never starts. We seal roofs, wet areas and structures with the right system for the surface — not a one-size-fits-all coat of hope.

Overview

Match the method to the problem

Waterproofing fails when the wrong product meets the wrong surface. We assess movement, exposure and substrate, then specify torch-on membrane, PU injection or a coating system that actually suits the job.

Every application is prepped properly — because adhesion, not the label on the tin, is what keeps water out.

Systems we apply

Three proven methods

Torch-on membrane

Heavy-duty bituminous membrane for flat concrete roofs, gutters and exposed decks.

PU injection

Polyurethane injected into cracks to seal active leaks in walls, basements and slabs.

Acrylic & cementitious coatings

Flexible coatings for bathrooms, balconies, planter boxes and retaining walls.

Wet areas

Bathroom and kitchen floors sealed before tiling to stop long-term seepage.

Basements & car parks

Negative and positive-side treatments for below-ground water ingress.

Roofs & decks

Full membrane systems with proper falls, upturns and protective screeds.

Good to know

Waterproofing questions

How long does waterproofing last?

It depends on the system and exposure — membranes and PU systems typically last many years when correctly installed. We’ll give the expected life and warranty in writing.

Can you waterproof without tearing out my tiles?

Sometimes. PU injection and certain coatings can treat leaks without full demolition. We assess first and recommend the least invasive option that will actually hold.

Do you provide a warranty on waterproofing?

Yes. Alongside our workmanship warranty, waterproofing systems carry material-specific coverage depending on what’s used.

Damp patch spreading?

Get it assessed before it reaches the reinforcement. We’ll recommend the right system and quote it fixed.
