| VDW stands for "in front of the wall = Vor Der Wand" drilling procedure. It is a vibration free and low noise procedure used for installation of single piles, as well as contiguous, tangential or secant pile walls. In the city centres space is precious and for this reason e.g. parking lots are moved under the earth's surface or even small gaps between buildings are filled. Featuring efficiency and environmentally friendliness is the VDW procedure well suitable for such projects.
Typical applications:
Pile walls (contiguous, tangential or secant type)
Drilling with casing for pile foundations
Well drillings
Injection drilling and ground improvement
Part or full displacement drilling |
