Common Waterproofing Solutions in Cape Town


Cape Town’s diverse property types require tailored waterproofing solutions. Here are some of the most common and effective methods we use:


1. Liquid Waterproofing Membranes

  • Advantages: Quick application, seamless finish, UV resistant.

  • Use cases: Flat roofs, concrete surfaces, and areas with complex shapes.


2. Cementitious Waterproofing


This method involves applying a cement-based coating that bonds well with concrete and masonry surfaces. It is often used in basements, water tanks, and swimming pools.


  • Advantages: Easy to apply, cost-effective, excellent adhesion.

  • Use cases: Foundations, retaining walls, and wet areas.


3. Bituminous Coating

  • Advantages: Strong waterproofing, good for underground use.

  • Use cases: Basements, tunnels, and foundations.


4. Polyurethane Waterproofing


Polyurethane coatings offer excellent elasticity and durability. They are suitable for areas exposed to heavy foot traffic and weather conditions.


  • Advantages: High flexibility, resistant to abrasion and chemicals.

  • Use cases: Roofs, balconies, and parking decks.


5. Injection Grouting


For cracks and leaks in concrete structures, injection grouting is an effective solution. It involves injecting waterproofing materials into cracks to seal them from the inside.

  • For flat roofs and terraces: Liquid waterproofing membranes or polyurethane coatings are preferred due to their flexibility and seamless application.

  • For basements and foundations: Cementitious waterproofing or bituminous coatings provide robust protection against ground moisture.

  • For areas with structural cracks: Injection grouting is the best choice to seal leaks without extensive demolition.

  • For swimming pools and water tanks: Cementitious waterproofing is ideal because it bonds well with concrete and withstands constant water exposure.
