Diaphragm walls – Reliable and stable

Diaphragm walls have a structural and/or sealing function and are suitable as support walls, cut-off walls or foundation elements. They are produced as concrete or reinforced concrete walls and are nearly impermeable for water. Excavation is carried out by duty-cycle cranes with suitable diaphragm wall grabs or cutters using a stabilizing slurry – your project, our methods.

Diaphragm wall (grab excavated)

Two different grab systems are available for diaphragm wall excavation depending on the requirements – suitable for typical wall thicknesses of 600 mm to 1,500 mm or even wider. The grab is lowered into the trench and the soil is conveyed cyclically. To verify verticality, measuring systems are always installed. 

Diaphragm wall (cutter excavated)

Trench cutters are used to construct diaphragm walls with regular wall thicknesses from 600 mm to 1,500 mm or wider – up to depths of 250 m. Trench cutters operate with two counter-rotating cutter wheels that continually loosen the excavated material, in a wide variety of soil types all the way to the hardest rock.
