Leaking roof? Rising damp? Water damage spreading through your property?
Our Stellenbosch waterproofing contractors fix moisture problems permanently. This historic university town's mountain valley location creates distinctive challenges: heavy winter rainfall from the surrounding peaks, valley humidity trapped beneath the oak canopy, and dramatic temperature swings between seasons. 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.

Stellenbosch’s mountain valley position means properties receive heavy winter rainfall while summer brings intense UV exposure. This combination accelerates roof deterioration. Heritage tile roofs crack under thermal stress. Modern metal roofs face corrosion from trapped valley humidity. 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 while preserving architectural character.
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.
Stellenbosch’s rising seasonal water table creates significant hydrostatic pressure against basement walls. Properties on mountain slopes face additional groundwater movement 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 from valley humidity.
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.
Stellenbosch’s mountain valley setting creates distinct waterproofing challenges across different areas:
Mountain slope estates (Paradyskloof, Welgevonden): Heavy rainfall runoff and drainage challenges on elevated properties
Historic centre (Mostertsdrift, Die Boord): Heritage homes with original waterproofing systems reaching end of life
Family suburbs (Dalsig, Coetzenburg, Brandwacht): Established properties needing modern protection solutions
Secure developments (Newinbosch, De Zalze): High-value properties requiring premium waterproofing systems
Local conditions require local expertise and products formulated for South African weather.
