Auxiliary structures

Smart construction requires smart methods. In both utility construction and civil construction, we have been adding value to this area for years. With our knowledge and experience, and with our smart equipment, we always achieve the optimal results.

Hydraulic stamping systems

Modular outrigger systems, combinable with hydraulics: strong, versatile and capacities from 20 to 700 tons

Heavy vaulting

Our special and strong beams span 24m and can be extended to 34m. They are used as formwork support, crash deck, bridge, vaulting, etc.

Smart super support

A movable formwork support, work platform and accessibility facility in one.

Auxiliary bridges

Our auxiliary bridges are specials. They are always composed for the specific situation and are suitable for the highest traffic loads.

The power of deBoer

Our auxiliary structures

Always custom-made

At deBoer we look at the specific technical objectives with a broad view. When applying auxiliary structures, each structure must be considered in relation to its environment and technical boundary conditions. This requires customization.

Large and small equipment

We have a large amount of equipment to provide a solution for small and large issues. Our equipment is developed as a modular system: our toolbox.

Knowledge and expertise

Through our involvement in hundreds of projects throughout Europe, we are familiar with many techniques and methods. A kind of hot-spot of knowledge in the field of the most diverse construction methods.

deBoer approach

Assistance work is custom work

Assistance work is always temporary and very specific to the project or problem. Every challenge requires its own approach. In order to arrive at the best approach, we sit down together to arrive at 'Best for Project'. We look at effectiveness, functionality, safety and environment.
We can draw on a lot of experience and excellent references from the past. We also create a suitable solution for your project.

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. That gives us flexibility and clout.

What do you need?

Explain your challenge to us and challenge us. There is always a solution.

That's why deBoer

A range of application areas

Civil technieken deBoer uses auxiliary structures for, among other things:

Viaducts and bridges: when these have become weakened or show serious damage, we transfer the loads to the auxiliary structures until final reinforcement has been applied.
Parking garages and precast concrete buildings: when the precast concrete structure of buildings has too little freedom of movement, cracks can form. In such cases we often use hydraulic outrigger constructions and temporarily take over the loads. This allows the repair to be carried out safely.
Renovation work: hydraulic outrigger constructions are often used when support points of bridges and viaducts need to be renovated. For example, in the case of concrete rot. In such cases, we temporarily transfer the loads safely to our auxiliary columns.
Formwork supports: for cast-in-place bridge decks with spans of up to 35 metres, we have the best solutions. Above railways, motorways or waterways, is familiar territory for us.
Auxiliary bridges: we are able to realize custom-made auxiliary bridges from our modular equipment. Our auxiliary bridges meet the highest standards and are suitable for heavy traffic in our main road network.
