Leaking roof? Rising damp? Water damage spreading through your property?
Our Helderberg waterproofing contractors fix moisture problems permanently. The region's mountain-coastal position means properties face both salt exposure from False Bay and heavy rainfall from the Helderberg mountains. We use locally manufactured Sealtek products designed for these exact conditions.
Every project includes a 5-year written guarantee, professional assessment, and installation by Sealtek Accredited Applicators.

The Helderberg’s combination of coastal humidity and mountain rainfall creates ideal conditions for roof deterioration. Metal roofs corrode faster near the coast. Tile roofs suffer from moisture trapped beneath the surface. By the time you notice ceiling stains, structural damage has already begun.
Our roof waterproofing works on all roof types: concrete tiles, metal sheeting, IBR, corrugated iron, chromadek, and asbestos encapsulation. Seamless liquid membranes eliminate failure points.
Damp walls create more than unsightly marks. Left untreated, rising damp destroys plaster, damages timber, and creates conditions for mould growth that affects your family’s health.
Our damp proofing treats the cause, not the symptoms. We identify moisture entry points through professional diagnosis, then apply 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.
Helderberg’s winter rainfall creates significant hydrostatic pressure against basement walls. Properties on mountain slopes face additional groundwater runoff that 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.
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.
The Helderberg region’s unique geography creates distinct waterproofing challenges:
Strand and Gordon’s Bay: Direct False Bay exposure means salt spray accelerates corrosion and coating breakdown
Somerset West: Mountain slope properties face heavy winter rainfall runoff
Inland estates: Temperature fluctuations between coast and mountain cause expansion stress
Beachfront properties: Constant humidity demands systems that resist moisture from both sides
