Looking for external waterproofing? We stock external waterproofing coatings like KÖSTER Deuxan 2C and external cavity drain membranes.

Tanking a Basement

You can use a tanking slurry such as KÖSTER NB 1 to tank a basement and keep the interior dry. The cementitious slurry creates a watertight layer than prevents moisture from entering. It penetrates deep into the substrate. It then reacts with moisture to make the substrate permanently waterproof.

As a waterproofing slurry system, NB1 can also be used for retaining walls, tunnels, reservoirs and car parks.

Basement Wall Tanking

Basement wall tanking is an easy process and an alternative to cavity drainage membrane systems. You need to ensure the substrate is clean and in sound condition. You can use a repair mortar to make watertight repairs to the basement walls. 

Dealing with Salt Contamination

If water from surrounding soil enters a substrate such as a basement wall, it can transport salts, contaminating the wall. You will need to deal with this salt contamination to prevent the salts from forming crystals. Left untreated these crystals can expand and destroy the building material and ruin any wall finishes /decoration.

KÖSTER Polysil TG 500 is a thin fluid salt-inhibitor product. It can be used in combination with waterproofing products to enclose the salt molecules and reduce their mobility.

KÖSTER tanking system

KÖSTER’s tanking system is reliable, using the highest quality wall tanking products to prevent water ingress. This system doesn’t require any external soil excavation, making it convenient and cost effective.
