BAM Construction specified Winn & Coales (Denso) specialist Densoseal 16A for sealing all electrical service cables ducts, with diameters of up to 300mm, in the external basement and lower ground floor walls.

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

Densoseal 16A Installation

Densoseal 16A is a self-supporting non-setting mastic which has been developed for sealing cable ducts and conduits against gas or water penetration. Description: Densoseal 16A is a firm fibrous mastic based on polybutene, mineral fillers, organic fibres and water displacing materials. Application: gas and water can accumulate in underground ducts - where ducts terminate inside buildings, manholes or chambers they must be sealed against gas and water. Densoseal 16A is suitable for applications where ducts are wet or liable to fill with water. Method: Densoseal 16A is packed into the ends of the duct by hand and moulded firmly around cables and against the duct ensuring there are no gaps or fissures. The mastic duct seal should be packed to a depth at least equal to the diameter of the duct . Properties: Densoseal 16A adheres to conduit and duct materials such as steel, earthenware, lead and PVC.
