Groundwater control technologies include a variety of applications. These barriers are designed to stop groundwater from migrating into a construction zone or from transporting hazardous substances down-gradient. The most common application includes subsurface barriers that are constructed using the slurry trench method. RECON has completed numerous groundwater control projects and our program managers and project managers oversee every aspect of the project to provide long-term and value-added solutions to our client’s most complex geotechnical challenges. Our common groundwater construction techniques include dewatering and construction cut off walls.
Dewatering is a groundwater control technique that is used at many construction sites to remove ground or surface water from solid materials or soils. This technique is a result of water accumulation in trenches, excavations, or places with slope.
Cut off walls:
Cut off walls are underground walls with very low permeability to impede groundwater flow and support excavation and structures. Cut off walls have been used for decades to provide cost-effective, long-term solutions for many groundwater control problems. Cut off wall construction requires the use of heavy specialized equipment – such as excavators, cranes and clam buckets – therefore work room is a factor that must be considered. To date, RECON has constructed over 10,500,000 square feet of slurry trenches.
