Sika is the market leader in concrete admixture technology. Combining this with our expertise in waterproofing has led to the development and evolution of the Sika® Watertight Concrete System, now the most widely used system of its type in Ireland.
The Sika® Watertight Concrete System provides waterproofing for:
- Lift pits
- Retaining walls
- Concrete facades
- Keeping water in e.g. Swimming pools
Sika® Watertight Concrete complies with BS 8102:2009 Type B Construction.
Whether keeping water out or keeping water in, a concrete structure can become truly watertight by using engineered waterproofing that incorporates the Sika® Watertight Concrete System. This rigid and integral system includes a full range of concrete admixtures for the production of watertight concrete, a complete spectrum of products for watertight joints and crack limitation, as well as design detailing and cost engineering for complex structures.
Waterproof concrete is normally an impermeable concrete. To obtain an impermeable concrete, a suitable particle-size distribution curve must be generated and the capillary porosity has to be reduced.
