Pretoria East is hilly: Erasmuskloof, Waterkloof and the ridge suburbs have plenty of homes cut into a slope with retaining walls, lower-ground rooms and basement garages. Below ground, water doesn't come from rain alone. It comes from the soil, pushing against the wall from the other side.
Foundation waterproofing Pretoria homes and builders need
New builds should have foundation waterproofing Pretoria builders apply before backfilling: a membrane on the outside face of the foundation and retaining walls, with a drain behind. On existing buildings where digging out isn't practical, polymer-cementitious systems can be applied on the inside face, because they bond to damp concrete and masonry and resist water pressure.
Basement waterproofing Pretoria homes and complexes
Basement waterproofing Pretoria work starts with finding the water: through the wall, up through the floor slab, at the joint between them, or from a failed drain. Then we seal cracks and joints and apply a negative-side cementitious system, and recommend drainage improvements outside if they're needed.
Parking deck waterproofing Pretoria
For complexes, shopping centres and offices, parking deck waterproofing Pretoria projects protect the slab and the steel inside it. Water carrying salts and oil through cracks rusts the reinforcing and spalls the concrete. We quote trafficable membranes and joint repairs for decks, ramps and podium slabs. These are larger jobs with a site inspection and written specification.
For body corporates & property managers
We supply a written condition report, a scope of work and a quote you can put in front of trustees. Request a site visit.
Damp at the bottom of above-ground walls is a different problem; see damp proofing & exterior walls.
