Viking Mercury FC
Description

Viking Mercury FC is a damp-proofing and tanking system that protects the below-ground portion of a building structure from water ingress. This torch-on system, consists of a polyester and fibreglass modified bitumen membrane that can be used for vertical and horizontal waterproofing applications.

It is applied as a single layer down to a depth of 3.5 metres, but when installed as a double layer, can go down to 10m below ground level. Typical applications include: under floor slabs; behind masonry walls and on substrates of in-situ or pre-cast concrete.
