Technology for Excavating Through Hard Ground

Shields for Bedrock/Boulders

It is possible to cut through composite ground that includes cobblestone or boulders and bedrock by equipping disc cutters for excavating bedrock in closed slurry shield machines, which are designed for water proofing, or in earth pressure balanced machines. Here are some of our business results in municipal base rock layers (composite ground), which have a comparatively higher amount of ground water.
