Expansion Joint Mastic Sealants

A selection of mastic joint sealants suited to expansion joints in concrete, brickwork and other substrates subject to natural movement over time. These can be neutral-curing, low modulus silicone expansion joint sealants, polyurethane expansion joint sealants or polysulphide expansion joint sealants (now more commonly replaced by Modified Polymer or hybrid polymer)

Please note; Expansion joints are also widely used for internal and external flooring, such as saw cuts and perimeter joints requiring a more rigid and hard-wearing cured sealant, these can be found in our FLOOR SEALANTS section - click here to see
