The smooth success of every building project depends on the preparation of a dry and stable surface. If an excavation pit is below the groundwater level, safe and proven procedures are required to prevent the build-up of water. The groundwater level is professionally lowered by Bartel-Bau before every project to make sure all subsequent building measures can be completed without interruptions. This can be achieved by replacing the soil and creating foundations, lift pits, sewer connections and mains connections. This allows us to either prevent the inflow of groundwater, drain the excavation pit or pump out inflowing water, depending on the most economical and efficient measure in each situation.
