Helderberg & Coastal Specialists
From Erinvale and Sitari to Strand and Gordon's Bay — Helderberg properties face brutal salt-spray and wind. Our marine-grade systems are spec'd for it.
— Why Somerset West Chooses Us
Helderberg properties typically lose galvanised flashings within 5–7 years. We replace them with grade-316 stainless and seal with high-modulus PU — work that's still watertight after a decade of salt exposure.

— Local FAQs
Standard silicone breaks down within 2–3 years in Helderberg salt air. Wind-driven rain then pushes water through the failed seal. Replacing it with a high-modulus polyurethane sealant solves the problem for 10+ years.
Yes — both are core service areas. Apartment block waterproofing in Strand is one of our most-requested services.
Salt air corrodes galvanised metal flashings, fasteners and reinforcing within years. Coastal waterproofing must use stainless steel (grade 316), polyurethane sealants, and UV-stable rubberised top membranes — not standard inland specifications.
The waterproof membrane under the tile screed has failed. The permanent fix is to lift the tiles, correct the slab fall, install a new liquid-applied or torch-on membrane, then re-tile. Patch repairs almost never hold.
