Recent jobs from Camps Bay to Sea Point: waterproofing, roofing, damp, and painting, all handled by our own team.
A full exterior restoration of this Sea Point complex on High Level Road. We stripped the failed waterproofing back to the slab, laid a geotextile membrane and a five-coat acrylic system across the roofs and balconies, and sealed the parapets. The facade was cleaned, all cracks and spalled concrete repaired, then primed and repainted.
This exposed parking deck was leaking into the space below through failed movement joints and worn waterproofing. We broke it out down to the structural slab, chased out and resealed the joints with backer rod and polyurethane, then primed the slab and laid a self-adhesive bitumen membrane across the deck. We detailed the upstands, columns, and drain outlets, cast a protection screed, and reinstated the paving.
A full renovation of this Hout Bay property, with the balcony rebuilt from the substrate up. We stripped the old tiles and the rotten deck back to the concrete, rescreeded the balcony, and laid a self-adhesive bitumen system with a cementitious waterproofing coat over the top. Three sliding doors were replaced with custom units and sealed, and a new grappa hardwood deck was fitted across the full balcony and balustrades. Inside, the guest bathroom was remodelled and the floors throughout were lifted and relaid on a self-levelling screed.
A full restoration of this multi-storey complex in Bantry Bay. We stripped the failed waterproofing on the flat roofs and parapets back to bare concrete, laid a geotextile membrane, and applied two saturation coats of acrylic waterproofing. Cracks across the facade and common areas were cut out and filled with polyurethane sealant, the balcony soffits and edges sealed against moisture, then the whole exterior was cleaned, primed, and repainted in the body corporate's colour.
