Economically upgrade and repair dikes that have suffered from severe surface erosion and growth of undesirable vegetation.
Presto Geoweb® Cellular Confinement System Dikes that protect three tanks at a petrochemical company in Sarnia, Ontario, Canada suffered from severe surface erosion problems and growth of undesirable vegetation. A cost-effective solution was sought to upgrade and repair the dikes to current standards.
The dike systems, surrounding tanks containing liquid petroleum products, required an impermeable geomembrane system to contain spills and prevent ground contamination in case of tank rupture. The petrochemical firm selected Presto’s concrete-filled Geoweb® cellular confinement system to protect the geomembrane and provide erosion control on the side slopes. The Geoweb system offered significant advantages over alternative systems considered for this project.
