Special sealant for motorway expansion joint repairsBack
© Reuse this A special road sealant supplied by abe Construction Chemicals, of the East Rand, was used for the sealing of more than 100 bridge expansion joints on Johannesburg’s M1 motorway. Technical sales representative Doug Richards says the expansion joints of the M1’s double-decker elevated section near Newtown were in urgent need of repair after sealants previously applied had disappeared from the joints. “The consultant, UWP Consultants, specified abe’s Dow Corning 888 special road sealant after detailed site inspections. “The specialist concrete-repair company, DSC/Zendon, was appointed to undertake the project,” Richards stated. Dow Corning 888 sealant has a movement accommodation factor of plus 100% and minus 50%, and was the suitable choice to cope with the extensive expansion joint movements caused by heavy vehicular traffic on the motorway. The sealing project had to be carried out at night and over weekends when traffic volumes were low. About 1 800 l of the sealant were used.
Dow Corning 888 sealant carries a five-year warranty from Dow Corning, subject to certain conditions. abe Construction Chemicals is the sole distributor of the Dow Corning range in sub-Saharan Africa.
