Efficient sealing
for dams and landfills

The membrane wall is a vertical sealing element that we mainly use for core seals in dams and for enclosing landfill sites. It has no static effect; however, it can also be used in conjunction with a statically effective support element (e.g. berm, sheet-pile wall, etc.) to enclose excavation pits.

Implementation

A membrane-wall screed is vibrated and pushed into the ground using a high-frequency vibrator with simultaneous slurry grouting. A continuous sealing wall is created by lining up individual screed sections.
