Delivery detailsBiokil Crown Toptank Tanking Slurry is a cementitious waterproofing material for use within a specified masonry or concrete tanking system. This listing is the 25kg grey tub, SKU 151PTG.
Typical applications
The manufacturer's listed applications include basements, cellars, foundations and wet-area walls and floors before their decorative finish. It must not be left as a final floor finish.
Specify the complete system
Assess the substrate, water exposure, floor-to-wall junctions and any required drainage before ordering. Below-ground waterproofing needs a coordinated design; a coat on one wall is not automatically a complete solution.
Before application
Obtain the current Toptank technical sheet for mixing, required components, coverage, coat build-up and curing. Confirm what the selected pack contains rather than assuming a separate liquid component is included.
Technical reference: Biokil Toptank product information. Follow the current instructions and safety data sheet before use.
