SIZE OF PROJECT
NATURE OF PROJECT
Dowsil® 890-SL self-levelling joint sealant was applied to several thousand linear metres of damaged joints on the busy OR Tambo apron. Sealant’s self-levelling characteristics makes it ideal for sealing irregular shaped joints and cracks.
Dowsil® 890-SL silicone joint sealant is a one-part, self-levelling silicone sealant for concrete and concrete to asphalt pavement joints. Sealant’s self-levelling characteristics make it ideal for sealing irregularly shaped joints and cracks by providing adequate adhesion to the interfaces, without the need for tooling. The sealant can withstand the joint opening to twice its width and closing to half its width, without adhesion loss. It requires no primer to bond to both concrete and asphalt. The sealant provides outstanding long- term performance in airport, bridge or highway joints in which extreme movement occurs. It is also jet fuel resistant.
Dowsil® 890-SL silicone rubber is virtually unaffected by sunlight, rain, frost, ozone or temperature extremes.
