COMPOSITION: A firm fibrous mastic based on polybutene, mineral fillers, organic fibres and water displacing materials. Preformed strip.
FIELD OF APPLICATION: Gas and water can accumulate in underground ducts such as those carrying telephone or electricity supply cables. Where ducts terminate inside buildings, manholes or chambers they must be sealed against gas and water. Densoseal 16A is especially suitable for those applications where ducts are wet or liable to fill with water.
METHOD OF APPLICATION
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 should be packed to a depth at least equal to the diameter of the duct. Surfaces should be free from loose rust, scale, dirt or previous sealants.
