Leaking roof? Rising damp? Water damage spreading through your walls?
Our Cape Town waterproofing contractors fix moisture problems permanently, not temporarily. The Mother City's combination of winter storms, coastal salt, and intense summer UV demands waterproofing systems built for local conditions. We use locally manufactured Sealtek products designed specifically for South African weather.
Every project includes a 5-year written guarantee, professional assessment, and installation by Sealtek Accredited Applicators.

Cape Town’s combination of winter storms and intense summer UV breaks down roofing materials faster than most regions. By the time you notice ceiling stains or bubbling paint, water has already damaged your roof structure.
Our roof waterproofing works on all roof types: concrete tiles, metal sheeting, IBR, corrugated iron, chromadek, and asbestos encapsulation. We apply seamless liquid membranes that eliminate the joints and overlaps where traditional systems fail.
Damp walls create more than unsightly marks. Left untreated, rising damp destroys plaster, damages timber, and creates ideal conditions for mould growth that affects your family’s health.
Our damp proofing solutions treat the cause, not just the symptoms. We identify moisture entry points through professional diagnosis, then apply appropriate Sealtek damp barriers to stop water penetration permanently.
A leaking roof needs proper diagnosis, not quick patches that fail within months.
Our leak repair process identifies root causes: failed flashings, corroded fasteners, cracked tiles, or deteriorated membranes. We implement permanent repairs using Sealtek’s liquid-applied systems that bond seamlessly to existing surfaces.
Stop paying for repeated temporary fixes.
Cape Town’s winter rainfall creates significant hydrostatic pressure against basement walls. This forces moisture through concrete, even through hairline cracks invisible to the eye.
Our basement waterproofing systems create continuous barriers that withstand water pressure while allowing trapped moisture to escape. We address both external water infiltration and internal condensation problems that affect properties throughout the Cape Peninsula.
Balconies take constant punishment from UV radiation, temperature changes, and rain. Over time, this produces cracking, joint separation, and grout deterioration that allows water into the slab below.
Our liquid membrane systems create seamless protection that moves with your building’s natural expansion and contraction. We waterproof over existing tiles where possible, avoiding costly removal and replacement.
Cape Town’s climate creates unique waterproofing challenges across different areas:
Atlantic Seaboard (Camps Bay, Clifton, Sea Point): Salt-laden air accelerates corrosion and coating breakdown
Southern Suburbs (Constantia, Newlands, Claremont): Heavy winter rainfall and established trees create drainage challenges
City Bowl (Gardens, Oranjezicht): Temperature fluctuations cause expansion and contraction stress
Northern Suburbs(Panorama, Bellville): Hot summers and cold winters demand flexible systems
