The power of deBoer

Our jacking techniques

We understand forces

No project is the same. High forces require a lot of knowledge and experience. This results in a well-considered and integral approach in which we always understand constructions.

High precision

With the help of our measuring systems we control and monitor the jacking process with great precision. Down to the millimeter. This enables us to guarantee very precise displacements.

Minimize disruption

We develop methods to relieve clients of their worries, taking the environment into account. We even lift bridge decks into traffic on a regular basis.

deBoer approach

Mortar work is custom work

That doesn't mean we always reinvent the wheel. Jacking is about existing techniques that we specifically translate to the use on your project. This sometimes requires a one-size-fits-all solution. On the other hand, jacking technology sometimes requires a specific and unique approach. That is where our strength lies. We analyse what our customers really need. This enables us to offer the best solutions for both simple and more complex relocation issues: Best for Project. That is leading.

Involvement

The earlier we are involved in projects, the better. We use our knowledge and expertise, if desired already in tender processes. Due to our involvement in hundreds of projects throughout Europe, we are familiar with many techniques and methods. A kind of hotspot of knowledge in the field of the most diverse construction methods.

On our own strength

We develop our own equipment, which forms the core of our standard solutions. If we don't have it, we make it in our own workshop. We use our expertise and collaboration with sister company Rijnstaal to quickly deliver custom work. This way, we always have a solution.

That's why deBoer

Custom solutions for any size

For small and large screw jack projects, you can contact deBoer. No question is too small, no challenge is too big. We have experience with a wide range of applications of screw jack techniques, including:

Infrastructure: lifting bridge decks or complete bridges. Whether it concerns prestressed decks, steel arch or cable-stayed bridges, we have done it all. As a specialist in replacing supports, jacking is often part of the work we perform.
Buildings and foundations: tensioning concrete structures with flat jacks or foundation piles, correcting settlements in buildings, supporting concrete structures for repairs, straightening buildings and preloading steel structures. Structural adjustments in existing buildings often involve temporary supports and jacking techniques.
Emergencies: fast and effective shoring and jacking solutions, such as supporting weakened structures with auxiliary structures. For example, viaducts to support the bridge deck, or cracks in concrete structures of buildings. We have the necessary equipment for a smooth approach.
