Comprehensive multi-layer balcony membrane application and complete internal wet area waterproofing for a modern two-storey home.
Architectural two-storey residence in the prestigious Melonba / Marsden Park estate featuring an expansive upper-level cantilevered balcony and complete internal wet area waterproofing.
Critical Balcony Waterproofing
Upper-floor balconies positioned directly above living spaces and garages are among the highest-risk zones for water damage in modern construction. Thermal expansion and structural deflection demand membranes with elongation exceeding 300%.
