Campbelltown in the Macarthur region holds some early colonial buildings alongside large postwar and newer estates, on reactive clay soils. The clay swells and shrinks strongly with the seasons, cracking footings and slabs and breaking down damp-proof courses. Older masonry without a course and slab homes on moving clay both get damp.
We confirm whether it is rising damp through a failed course or moisture through a cracked slab edge, then treat with DPC injection, slab-edge work or drainage and a breathable, salt-resistant finish.
Campbelltown's mix of older homes and newer estates sits on reactive clay in the far south-west. The clay's strong wet-dry movement cracks footings and slab edges and breaks down damp-proof courses, so moisture rises through older walls and pushes in at slab edges in newer ones, leaving salts and blown plaster.
Campbelltown's reactive clay keeps subfloors damp after rain. We fit a subfloor ventilation system to dry the underfloor.
Moving clay cracks footings and breaks down the DPC. Our rising damp treatment injects a new course.
We re-coat with breathable replastering that resists salt.
Our mould removal clears it and fixes the moisture source.
