Newton HydroCoat Tanking Slurry – Cementitious Waterproof Coating
Newton HydroCoat Tanking Slurry is a single component, mineral coating that is simple to mix and easy to apply. Unlike conventional slurries, HydroCoat Tanking Slurry includes advanced crystallising and capillary-blocking chemicals that also enhance the monolithic bond of the coating to the substrate.
HydroCoat Tanking Slurry can be applied both internally and externally to a variety of substrates to form an effective barrier against positive and negative hydrostatic pressure, as well as non-pressurised moisture in the ground for use in damp-proofing applications. Applied in two coats, the 2mm coating is waterproof against water pressure of up to 7 bar. In addition to increasing the bond, the penetrating crystallising chemicals react with water and the calcium hydroxide within the concrete to actively seal developing micro-cracks.
The product is available in 20kg bags, or with the bags within a sturdy plastic container which doubles as a mixing bucket and is supported by BBA Certificate 23/6962, and so accepted by the NHBC as a suitable waterproofing system for Type A Waterproofing to Grades 1, 2 and 3 – BS 8102:2022. Just add water, mix and apply!
