No loss and no contamination of drinking water

Sika Solution: Admixtures and mortars for watertight concrete

With the Sika Watertight Concrete Concept, the load bearing concrete structure simultaneously becomes the sealing shell. The latest admixture technology and concrete mix designs are used in combination with high quality joint sealing systems to achieve a watertight concrete structure. With this, no additional externally applied coatings are needed.

Sika Solution: Waterproofing Membranes for 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 defective waterproof barrier had compromised the water quality due to contact with the concrete. The most straightforward and effective solution consisted in relining the tank with Sikaplan® WT 4300-15C Felt waterproofing membranes.

Sika Solution: Joint sealing systems for waterproof structures

The main purpose of joint sealing systems is to prevent water from entering or exiting a structure while permitting limited movement of the substrates. Sika offers various joint sealing systems such as waterstops, adhesive tape systems, swelling profiles and injection hose systems.
