Waterproofing Specialists in Cape Town

Common signs include water stains, peeling paint, bubbling plaster, mould, damp smells, cracked sealants and visible moisture after rain. Water may also collect on flat roofs, balconies or other surfaces instead of draining correctly. A professional assessment can help identify the source and extent of the problem.

We provide waterproofing solutions for roofs, balconies, terraces, parapets, joints, penetrations and other vulnerable areas. Our services include torch-on waterproofing, waterproofing repairs, sealant work and damp-related assessments.

Yes. We assess the affected area, identify visible defects and consider how water may be entering or collecting. We then recommend a suitable waterproofing or remedial solution based on the surface, condition and source of the problem.

Torch-on waterproofing uses a bituminous membrane that is heated and bonded to a suitably prepared surface. When correctly specified and installed, it creates a continuous waterproof layer commonly used on flat roofs and other compatible surfaces.

No. The substrate, roof design, drainage, existing materials and surrounding fire risks must be assessed first. Where torch-on waterproofing is unsuitable, an alternative system may be recommended.

Yes. Balconies and terraces are vulnerable to water penetration around tiles, joints, edges, outlets, door thresholds and wall connections. The correct solution depends on whether the problem is caused by failed waterproofing, defective joints, poor drainage or another source.

In some cases, a waterproofing system may be applied over a suitable tiled surface, but this depends on the condition, stability and preparation of the tiles and joints. In other cases, the tiles may need to be removed to access and repair the underlying waterproofing system.

Common causes include poor surface preparation, incorrect product selection, inadequate drainage, movement or cracking, damaged flashings, failed sealants, blocked outlets, incorrect installation and deterioration caused by age or weather exposure.

Yes. Localised repairs may be possible when the damage is limited and the surrounding system remains serviceable. If deterioration is widespread or the existing system has repeatedly failed, a more extensive restoration or replacement may be required.

Depending on the system installed, and based on manufacturer guarantees. It could be anything between 2-10 years.

The timeframe depends on the size and condition of the area, the waterproofing system selected, surface preparation requirements and the weather. Small repairs may be completed quickly, while larger roof or balcony projects may require several days.

Most waterproofing products require a dry, properly prepared surface and suitable weather conditions. Rain, strong winds, excessive moisture or low temperatures may delay the work or affect the performance of the system.

Waterproofing may resolve mould or damp caused by external water penetration, but not every damp problem comes from failed waterproofing. Condensation, plumbing leaks, rising damp and inadequate ventilation can produce similar symptoms. The source should be identified before work begins.

Waterproofing is generally used to prevent liquid water from entering through exposed surfaces such as roofs, balconies and walls. Damp-proofing addresses moisture movement through building materials. The correct treatment depends on the source and nature of the moisture.

Yes. Joints, cracks, flashings, pipes, outlets and other penetrations are common water-entry points. We assess these areas and use suitable detailing or sealants where appropriate.

Yes. After assessing the property and determining the required scope of work, we provide a quotation for approval. If additional defects are discovered during the project, they will be discussed with you before extra work proceeds.

Guarantees depend on the type of work, the selected waterproofing system, the existing condition of the property and the products used. Any applicable workmanship or product guarantees will be explained in the quotation.

We recommend periodic inspections and additional checks after severe storms or when signs of water penetration appear. Roof outlets, joints, flashings, sealants and drainage areas should be kept clear and maintained.

It is helpful for someone to provide access and explain any visible signs of leaking or damage inside the property. However, the arrangements will depend on the property and the areas that need to be inspected.
