Single-component, highly flexible compound used for sealing conduits and pipes through service duct sleeves. An incredibly effective pipe sealant, the compound seals around numerous services within the sleeve, even where significant water ingress exists.
The unique pipe sealant compound never cures, remaining permanently flexible, allowing for new services to be simply pushed through the existing repair and resealed.
Newton 308 Stopaq swells by up to 10% when in contact with water and will seal the service duct against water pressure of up to 3m of water pressure and will form a very effective seal against gas and water vapour.
Newton 308 Stopaq adheres to both wet and dry surfaces of concrete, mortar and plastic without the need of a primer. The swelling characteristics do not create any stresses to the service joint or the structure.
Once the service sleeve is sealed, Newton Stopaq FR Mortar is used to cap the installation. Stopaq FR Mortar is a fibre reinforced non-shrinking fire resistant mortar specially produced for use with Newton 308 Stopaq that can receive new cables or conduits without the use of power tools.
