Dowsil 888 (formerly Dow Corning 888) is a Non-sag, low modulus silicone joint sealant for Portland cement concrete pavement joints which is able to accommodate large ranges of expansion and contraction.
For use in new construction, repair or remedial applications. Dowsil 888 Silicone Joint Sealant may be used to seal joints that are not uniform in width provided the movement capability of the sealant is not exceeded. May also be used in joints with minor spalling. Trusted by the American Military on many of its bases, Dowsil 888 has now been adopted by both the Australian Federal and Local Northern Territory Governments on both Defence and Civilian Construction Projects.
