Product Description

Expanding Hydrophilic Water Bar


NATSEAL is an elastic strip of a special mixture containing sodium bentonite and butyl rubber formulated to stop water infiltration through voids and cracks in concrete joints. It can easily be applied onto the substrate, and can easily follow the substrate shape.


NATSEAL has a distinct advantage over similar products due to a considerable amount of butyl rubber in the formulation. It can withstand rainfall and contact with water for a considerable length of time after application, prior to the next concrete pour. It will not disintegrate even after 48 hours of premature water contact. Sold in 1 meter lengths.

Usages: Concrete Repairs, Tanking.

Sectors: Utilities, Construction, Civil Engineering, Railways, Sea Defence, Mining.
