Construction, Remediation and Rehabilitation of Dumpsites

The securing of contaminated landfills by cut-off walls, combined cut-off walls (inserted steel profiles or liner sheets) and compartment cut-off walls including the rehabilitation of pump shafts, is part of our service. In addition to enclosing landfills, we also offer the replacement of contaminated soils by large replacement borings. We excavate contaminated materials hole by hole using a temporary circular casing and backfill the excavation with uncontaminated material. By overlapping all drill holes, the contaminated mass is completely replaced.
