Our waterproofing services
What We Waterproof
Roofs get the most attention, but water finds its way through walls, balconies, basements and bathrooms too. Here's what we handle.
Roof Waterproofing Cape Town
Flat roof waterproofing, tiled roof waterproofing, concrete roof waterproofing and metal roof waterproofing across Cape Town. We assess the roof type, slope and existing condition before recommending torch-on, acrylic or liquid rubber waterproofing solutions. Every roof gets a tailored approach.
Wall Waterproofing
When paint peels off your exterior walls six months after painting, it's not the paint, it's moisture behind the surface. We treat the wall from outside in, stopping water before it reaches your plaster. Parapet walls, boundary walls, retaining walls, same approach, different coatings.
Balcony & Deck Waterproofing
A leaking balcony drips into the room below, stains the ceiling, weakens the slab. We apply a bonded membrane that moves with the concrete instead of cracking away from it. In many cases we waterproof balcony flooring without removing tiles. Saves time and money on slab waterproofing.
Basement Waterproofing
Cape Town has a high water table in many suburbs. Groundwater pushes against basement walls with real force. We use cementitious tanking and drainage membranes built for that kind of pressure, keeping underground parking, cellars and storage rooms bone dry.
Bathroom & Wet Area Waterproofing
Tiling over a shower floor without waterproofing underneath is a ticking clock. Within two years, water tracks through grout lines into the screed. We prep showers, bathrooms and kitchens before tiling so the water stays where it belongs.
Emergency Leak Repairs
Water coming through your ceiling right now? Our emergency crew responds same-day across Cape Town. We do leak detection on the spot, find and fix roof leaks fast, then give you a straight answer on the repair cost. Call us, even in heavy rain.
Roof Repairs & Maintenance
Cracked ridge caps, loose flashing, blocked valleys, broken tiles. Half the leaks we see started as small roof damage that nobody fixed for two winters. One maintenance check a year costs a fraction of what the water damage repair bill will.
Commercial & Industrial Waterproofing
Shopping centres, office blocks, factories, body corporate complexes. Bigger roofs, tighter timelines. We work after hours and weekends when tenants can't be disturbed. We also issue waterproofing certificates and reports for property transfers, insurance and NHBRC compliance.
Damp Proofing
Rising damp creeps up from the ground. Lateral damp pushes through from outside. Condensation forms when ventilation is poor. Three different problems, three different fixes. We test first, then treat the actual cause, not just the symptom.
Waterproofing solutions Cape Town
Six Waterproofing Solutions. One Right Answer for Your Roof.
Professional waterproofing solutions for every roof type in Cape Town. The method depends on your roof type, slope, sun exposure and where the water is getting in.
Torch-On Waterproofing
Modified bitumen sheets welded together with a gas torch. The go-to for flat concrete roofs in Cape Town. We work with Derbigum and other proven brands. Properly installed, you're looking at 15 to 20 years. Price per square metre depends on layers and system.
Acrylic Waterproofing
Brushed or rolled onto the surface, reinforced with a fibre membrane between coats. Works on pitched roofs, parapets and joints where torch-on can't go. Products like Hydroflex give a spray-on option for faster coverage on bigger roof areas.
Liquid Rubber Waterproofing
Goes on as a liquid, dries into a rubber sheet with no seams. Wraps around pipes, corners and odd shapes without cutting or patching. UV stable enough for exposed Cape Town sun. Ideal for detail work that sheet membranes can't handle.
Bitumen Waterproofing
Heavy-duty petroleum-based system for below-ground work. Foundations, retaining walls, anything sitting in soil where water pressure is constant. Not pretty, but nothing else holds up underground the way bitumen does. Often paired with drainage boards.
Cementitious Waterproofing
A cement-and-polymer mix that becomes part of the concrete itself. Bathrooms, swimming pools, water tanks, basement walls. It doesn't peel because it's bonded into the substrate. We use Coprox and Penetron depending on the application and exposure.
Polyurethane Membrane
The most flexible option we use. Cape Town can swing 20 degrees in a single day — concrete expands, inferior coatings crack. Polyurethane stretches with the movement and snaps back without splitting. Lasts up to 25 years with zero maintenance.
Common problems we fix
Recognise Any of These?
Most people call us after ignoring one of these for a season or two. The sooner you get it looked at, the cheaper the fix.
Roof leaking during rain
Water dripping through ceiling, stains appearing on walls or ceiling after rainfall.
Rising damp on interior walls
Damp patches, peeling paint or mould appearing at the base of your interior walls.
Cracking and spalling concrete
Water penetrating concrete causes reinforcing steel to rust, leading to cracks and structural weakening.
Mould and musty smells
Persistent dampness creates the perfect environment for mould growth, affecting your family's health.
Water pooling on flat roof
Standing water on your flat roof signals drainage problems and accelerates membrane deterioration.
