Foundation & Excavation Solutions
Three expertise combined
Ballast Nedam deploys a lot of expertise daily, foundation & excavation solutions included. Foundation & Excavation combines three separate expertise: Ballast Nedam Specialist Earthmoving, Van Leeuwen Anchors and Ballast Nedam Foundation Techniques. These expertise are reflected in Ballast Nedam's major non-residential and infrastructure projects.
Foundation engineering is the basis
Ballast Nedam is one of only a few companies offering the complete range of activities required to create a stable foundation. This enables them to simplify interfaces. Thanks to the experience and knowledge gained from major projects, Ballast Nedam Foundation & Excavation Solutions professionals know what is involved in such a project. They understand the challenges our clients face and have the right experience to master them.
Secondly, we have the GEWI anchors. These GEWI bars are inserted into the ground with a hollow tube and injected with grout, after which the tube is pulled out of the ground.
The last and third anchoring technique is the use of (removable) strand anchors. These strands are often used in temporary or permanent constructions and are installed similarly to GEWI anchors. They can be fitted with a special block at the end, allowing them to be removed again if required.
Van Leeuwen has developed two specific types of piles. Firstly, the LEKA piles, which are steel tubular piles that we drive into the ground. With this foundation technique, the piles are formed in the ground without any vibration. They are usually used when there is limited work space. In addition, the VF pile, also known as the Vibro Fluidation pile, makes it possible to accurately determine the grout column's length and reduce grout spillage. Because the VF pile is pulled up after the steel core is placed, the pipes can then be injected with grout.
