Diaphragm walls

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. 

Diafragmawand frees uitgegraven

Sleuvenfrezen worden gebruikt om diafragmawanden te bouwen met reguliere wanddiktes van 600 mm tot 1.500 mm of breder - tot dieptes van 250 m. Sleuvenfrezen werken met twee tegengesteld draaiende freeswielen die voortdurend het uitgegraven materiaal losmaken, in alle mogelijke grondsoorten tot en met het hardste gesteente.
