Cutoff walls are used for both environmental and civil projects. Cofra has many years experience in the manufacture and installation of Geolock cutoff wall. With Geolock, Cofra has realised projects in Europe, North America and Asia. Geolock is used for the isolation of existing waste disposal sites and the waterproofing of dikes, dams and motorways in cuttings. Geolock has an infinite number of applications and is competitive with traditional materials. Wherever a horizontal underground flow of groundwater, contaminated or otherwise, has to be blocked, Geolock offers the optimal watertight cutoff wall solution.
