Mineral based waterproof slurry
AQUAFIN®-1K One component mineral based waterproof slurry „Negative waterproofing!“. Problems solved.
Why AQUAFIN®-1K AQUAFIN-1K is a rigid waterproof slurry for the inside and the outside. It resists the sulfate and is suitable for all types of support in the construction. It is open to diffusion, resistant to ageing and UV. In addition, it is certified waterproof against negative water pressure up to 1.5 bar.
How does it work? After application, a strong bond is created between the support and AQUAFIN-1K, which becomes an integral part of the substrate. AQUAFIN-1K thus forms a waterproof barrier.

What is negative waterproofing? The typical case of a negative waterproofing exists when water penetrates a wall by a face and the waterproofing layer is applied on the opposite side. To make a negative waterproofing is more difficult than to make a positive waterproofing because then, the water has crossed the construction element, has arrived at the level for example, the layer of paint or tile flooring and tries to take it off from the wall.
Example of construction where a negative waterproofing is required: • Internal waterproofing of cellar walls • External waterproofing of water tanks • Internal waterproofing of elevator shafts • Internal waterproofing of tunnels • Waterproofing of low permeable floors
