Description

Densoseal 16A is a firm, fibrous mastic based on mineral fillers, organic fibres and water displacing materials. It is a non-setting, self-supporting mastic which may be applied to wet surfaces and will seal ducts and conduits against ingress of gas and water. It complies with British Telecom Specification M212C. Used for sealing cable ducts, conduits and service entry pipes or sleeves particularly below ground level to prevent the entry of gas or water into buildings. It may also be used for profiling mechanical joints on hot pipes to allow application of tapes.

Densoseal 16A is packed into the ends of the duct by hand and moulded firmly around cables and against the duct to ensure there are no gaps or fissures. The mastic should be packed to a depth of at least equal to the diameter of the duct. Surfaces should be free from loose rust, scale, dirt or previous sealants.
