Mastics, joint sealants and injection tars 

Our broad portfolio of mastics, joint sealants and injection tars are used to seal joints and openings between two or more substrates. Their main purpose is to prevent air, water, and other environmental elements from entering or exiting a structure while permitting limited movement of the substrates. Our joint sealants are silicone, polyurethane-, hybrid- and polysulfide based and suited for a variety of architectural applications, such as windows, roofing terminations as well as water and wastewater treatment facilities. Our product range includes hydro-swelling gaskets, highly resistant sealing tapes for unconventional joints as well as injection hose waterstop systems for cold joints in concrete.
