Pro-Build Tanking Slurry is a ready mixed, plastic modified and hydraulically setting powder.
When Pro-build Tanking Slurry is applied to concrete, cement renders, lime renders or masonry, a portion of the hydrophobic substances penetrates into the capillary system of the substrate. These substances fill the capillaries and stop the passage of water and become an integral part of the structure, thus forming a monolithic bond.
Although we would always suggest you need to try and allow the walls to breathe, it is sometimes necessary to seal the walls from the inside. A cement based waterproofing slurry is one way to achieve this.
To keep walls as dry as possible, it’s important that there are breathable external finishes to allow any rising moisture to wick away to the outside eg bare stone or brick or lime renders and a limewash or a mineral paint. Do not seal the inside of a wall that is effectively sealed on the outside.
Pro-Build Tanking Slurry can be used in a wide range of areas, for commercial and domestic properties as well as in building, construction and civil engineering projects.
Tanking Slurry may be applied to the positive and negative side of a structure against pressure water, ground moisture and dampness. It can be used to waterproof both old and new structures, internally and externally. The Tanking Slurry bridges hairline cracks, resists freeze/thaw cycles, is non-toxic, non corrosive, prevents efflorescence and is resistant to chemicals.
