Developed for waterproofing against ground moisture and pressurised water, KÖSTER KB-Flex 200 forms a reliable seal across an extensive range of materials.

The system does not shrink or dry out, therefore remaining permanently plastic.

Because of this, cables can be installed into the finished waterproofing material at a later date if necessary.

For sealing around pipe penetrations, Delta provides a one-sided corner strip sealing tape.

This creates a vapour seal which can also be used for patch repairs and detailing.
