Densyl Mastic is a self supporting non-setting mastic for waterproofing and for sealing service entries and ducts against entry of gas. It has been evaluated by British Gas and found suitable for sealing the annular space between carrier pipes and sleeves where services enter buildings below ground level.
This mastic is widely used for moulding around irregular profiles such as flanges, mechanical joints and valves to provide a contour suitable for wrapping with anti-corrosion tapes.
Soft mouldable mastic based on saturated petroleum hydrocarbons, inert mineral fillers and organic fibres.
Densyl Mastic strips can be rapidly applied to provide an effective gas and water tight seal capable of accommodating movement due to settling, subsidence or vibration (where ducts are wet or a substantial head of water could form, Densoseal 16A should be used).
This Pack contains 1 x 3KG block.
