Our Waterproofing Services in Randburg & Sandton

Roof Waterproofing & Roof Repairs

Roof leaks are among the most common problems in older Randburg homes and high-rise office blocks in Sandton. We handle all roof types — pitched, flat, tiles, metal — restoring structure, replacing damaged sheeting, sealing joints, and ensuring effective drainage.

Balcony, Terrace & Basement Membrane Systems

Water ingress in balconies or underground areas can lead to serious structural problems. We apply torch-on or liquid membrane systems, depending on the substrate, and protect these areas so rainwater or burst pipes no longer threaten the interior.

Damp & Rising Damp Proofing

Walls showing mold, peeling paint, or efflorescence signal moisture issues. We install damp‐proof courses, use breathable coatings, and provide specialist treatments to stop rising damp and repair moisture damage.

Sealing & Flashing

Proper sealing around windows, doors, parapets, roof penetrations and other vulnerable points is essential — especially in Sandton’s mixed commercial and residential buildings. We use robust flashing, sealants, and co-epoxy or polyurethane solutions that withstand harsh weather.

Maintenance & Inspections

Many clients only call when water damage appears. We offer scheduled maintenance, roof checks, gutter cleaning, and preventive sealant re-applications. Regular inspections help you avoid expensive repairs down the line.
