Waterproofing Atlantic Seaboard
Salt-grade roof, parapet and balcony waterproofing for the apartment blocks, villas and cliff-side homes along the Atlantic Seaboard.
Waterproofing Atlantic Seaboard work is a different brief to inland Cape Town. The salt-laden onshore wind strips loose membrane within a season of any failure, eats aluminium apron flashings faster than anything outside Strand, and corrodes anything other than stainless-steel fasteners on parapet detailing. The detailing has to be specified for the exposure — not lifted from a standard residential spec.
Send one enquiry and we arrive on-site to identify the actual failure point — usually a parapet apron, a perished membrane edge or a corroded balustrade penetration. Fixed written quote in your inbox the same business day. Submit a free quote request or call 021 815 1608.

Frequently asked questions
Why does Atlantic Seaboard waterproofing cost more than inland Cape Town?
Salt-laden onshore wind eats apron flashings, parapet caps and exposed membrane edges roughly two to three times faster than inland exposure. Marine-grade aluminium gutters, stainless-steel fasteners and mineral-chip-topped torch-on membranes are the spec — and they cost more than the standard inland kit. Typical price uplift on Sea Point, Camps Bay and Bantry Bay scopes is 10–15%.
How do you handle body-corporate scopes on Sea Point apartment blocks?
Section-by-section schedule, fixed written quote per block, traffic-marshalling around residents during torching operations, and the workmanship guarantee certificate issued per section on completion. We have done multiple perimeter parapet refurbishments along the Sea Point strip and can scope by elevation or by zone, whichever the trustees prefer.
Do you work on cantilever balconies in Bantry Bay and Clifton?
Yes. Cliff-position balcony work needs rope access or crane stage rigging, weather-window discipline (we cannot torch in onshore gusts), and liquid polyurethane systems that cure in 24-hour cycles rather than torch-on that demands a longer dry window. Penetration detailing around balustrade fixings is what separates a 12-year job from a three-year one.
What about Camps Bay villa decks and entertainment terraces?
A three-layer build: a fully bonded liquid polyurethane or torch-on membrane on the slab, a granolithic screed-and-tile finish that takes furniture and foot traffic without trashing the layer underneath, and proper detailing around drains, balustrade fixings and lighting plinths. Most failures we are called to inspect are at the penetration detailing — not the membrane field.
Is the workmanship guarantee in writing on coastal jobs?
Yes — and we carry the guarantee at the same period as inland work (typically 10 years on a properly applied torch-on or polyurethane membrane, 5 years on damp). The salt-exposure detailing is what earns the guarantee. We will not cut spec to win price on an Atlantic Seaboard scope.
