Sika 1 Waterproofing System

Safeguard are pleased to be an official distributor in the UK for Sika waterproofing products.

The Sika 1 multi-coat render waterproofing system has been used for waterproofing basements and underground structures for more than 80 years.

Sika 1 is compatible with OPC and SRC. It can be overplastered, coated or decorated, and is compatible with water quality regulations.

As with all tanking systems, particular attention needs to be given to the detailing of the wall-floor junction. A typical detail for a four-coat system is shown in the diagram on the right. For further information, please contact our technical department.
