A project showcase that pays testimony to the longevity of a.b.e. Construction Chemicals’ silicone joint sealants – perfect surfaces, years later.
They say the proof of the pudding is in the eating, but when it comes to sealants, these products’ success is determined by the longevity of the structures that they were applied to.
a.b.e. Construction Chemicals’ Dow Corning® 888 and Dow Corning® 890-SL silicone joint sealants are two such benchmark products that have proven their durability through projects that, years down the line, still pay testimony to their quality.
Roads and bridges
Dow Corning® 888 Silicone Joint Sealant was applied 15 years ago in the Thrupps Centre parking area at the Rivonia Road entrance, 13 years ago on the M1 double-decker bridge and was also used to seal joints on the Gautrain viaduct six years ago, all structures which are still in great condition.
A non-sag material that can be applied over a wide temperature range, Dow Corning® 888 Silicone Joint Sealant can be used in new construction or for repair and remedial applications. It may be used in joints not uniform in width, provided the movement capability of the sealant is not exceeded. (+100%, -50%)
Dow Corning® 890-SL Silicone Joint Sealant is a one component self-levelling product designed to seal unprimed concrete surfaces as well as concrete-to-asphalt pavement joints, whether it is new construction, repair or remedial applications. It can also be used to seal irregularly shaped and minor spalled joints.
Being self-levelling, no tooling is required and the product is dispensed directly from a 857ml cartridge or in the case of major works, from 20Lt pails or 189Lt drums via air-powered pumps.
a.b.e Construction Chemicals has supplied this product for many airport projects, including OR Tambo International Airport, Polokwane International Airport and moving beyond local borders, at airports in Swaziland and Botswana. It is currently being applied at Kusile and Medupi Eskom power stations.
Durability and strength
Both Dow Corning® 888 and Dow Corning® 890-SL Silicone Joint Sealants have excellent movement capability and can handle compression. They are also weather- and ultraviolet-resistant to last for many years.
