Damp and Waterproofing for Big Bay and West Coast Homes
By Big Bay Painters - Expert advice from the professionals
West Coast homes face a double challenge when it comes to moisture — the heavy winter rainfall that drives water against exterior surfaces, and the year-round salt air that accelerates the breakdown of waterproofing systems. Damp and water ingress are among the most common and costly problems affecting Big Bay, Bloubergstrand and Table View properties.
Where Water Gets In on West Coast Homes
The most common water ingress points on West Coast homes are: flat roof sections and parapets where ponding occurs after rain; horizontal surfaces that collect water and allow it to penetrate through cracks; window and door reveals where the seal between frame and wall has failed; and cracked render on west and south-facing walls exposed to wind-driven rain. Identifying the entry point correctly before treating is essential — waterproofing applied over the wrong area will not solve the problem.
Flat Roof Waterproofing
Many Big Bay and Bloubergstrand homes have flat roof sections above garages or as part of the architectural design. Flat roofs are particularly vulnerable in the Western Cape winter and require a purpose-designed waterproofing membrane — not simply paint or a generic sealer. Professional waterproofing of flat roofs typically involves cleaning, crack repair, application of a reinforcing membrane and a protective topcoat. This system, properly applied, should last seven to twelve years.
Waterproof Paints vs Proper Waterproofing
Many homeowners confuse waterproof exterior paint with proper waterproofing. Waterproof paints — products like Plascon Damp Proof or similar — provide a degree of moisture resistance on sound walls but are not a substitute for structural waterproofing on flat roofs, parapets or areas with active water ingress. If you have a water ingress problem, get a professional assessment of the entry point and the appropriate solution before any products are applied.
