Reinforcement Mesh for HydroBond 2K-Flex

A radon gas certified, bitumen/rubber waterproofing membrane used primarily for the external waterproofing of earth-retaining structures such as basements and foundation walls. Forms a thick, highly flexible barrier to water ingress that can be applied to fill voids, cracks and joints.

Environmentally friendly and solvent-free, HydroBond 2K-Flex consists of two components; a bitumen emulsion and a reactive powder. These two components chemically react when mixed to produce a firm, yet still highly flexible coating that can be applied by trowel or by airless spray machine. Adhering insulated panels to concrete, masonry and thoroughly dried thick bituminous coatings, 2K-Flex dries quickly and is rain-fast after a short period.

HydroBond 2K-Flex requires two ancillary products, HydroBond 2K-Flex Primer and HydroBond 2K-Flex Mesh.

HydroBond 2K-Flex Mesh

A reinforcing mesh made from woven fibreglass yarns and coated with an alkaline resistant latex which prevents the alkaline present in cement from degrading the glass fibre.
