The process of global population growth is making clean water an increasingly scarce commodity. The careful management of water consumption, purification and storage as well as wastewater treatment is essential. Already today, one billion people suffer from a lack of drinking water.

Sika solutions for an adequate supply of clean water

  • Concrete produced with Sika® ViscoCrete® admixtures requires up to 15% less water than concrete mixed using standard procedures
  • Watertight concrete and interior coatings for drinking water reservoirs reduce water losses
  • Spray-applied waterproofing membranes for watertight structures and wastewater treatment plants reduce contamination

Example: Drinking water tanks

On the Jungfraujoch saddle, high up in the Bernese Alps, a Sika product was used to reinstate a drinking water tank. The tank had sprung a leak and the water quality was compromised through contact with the concrete. The most straightforward and effective solution consisted in relining the tank with Sikaplan® WT 4300-15C Felt sheet waterproofing membranes.
