Waterproofing Bellville

It depends heavily on whether the plaster has to come off. Where the damp course has simply been bridged by raised ground level, the fix is largely external and modest. Where plaster is salt-contaminated and has to be removed and reinstated, that replastering is usually the larger share of the cost, and we quote it separately from the damp work so you can see both.

In older Bellville housing the most common reason is that the plaster was never removed. Sea sand in mid-century mixes left salt through the plaster, and salt draws moisture from the air on its own regardless of how well the wall behind it was treated. Painting or replastering over it produces exactly the failure you have had twice.

Walk the outside of the house and look at where the ground meets the wall. Paving, soil, gravel or a bed sitting level with or above two or three brick courses up from the original ground line is the giveaway. Bridged is far more common than failed, and it is a much cheaper problem.

It usually turns on whether the water is arriving through common property such as an external wall, a roof or a parapet, or from within your own section, and schemes differ. A written report on where the water is entering is generally what the body corporate needs before anything can be decided. We work with managing agents regularly.

Yes. Office blocks, older commercial stock and light industrial buildings, particularly flat concrete roofs with parapets and sheeted roofs with failing fixings. We quote through property managers and body corporates as readily as through owners.
