Willemen Infra is a leading, Belgian road construction company with a regional presence in both Flanders and Wallonia. An important asset is that we have all aspects of the construction process under our own management and thus fully control the execution. Moreover, our team of 1,000 well-trained and experienced employees are willing to work at night and over the weekend to make sure they get everything done in time. In addition, thanks to our own COPRO-certified production and recycling sites, we are one of the leading producers for asphalt and road concrete.
- General roadworks
- Asphalt works
- Concrete works
Our greatest trump card when it comes to general road works is undoubtedly the fact that we can take care of all the work ourselves without having to depend on other contractors or suppliers. Naturally, our asphalt production plants and mobile concrete mixing plants play a crucial role in this. The term ‘general road works’ covers the following activities:
In road construction, it is often necessary to supply and remove, backfill, dig or move earth. The surfaces also need to be contoured or compacted. We have the proper equipment (such as cranes or caterpillar bulldozers with GPS control systems) and the right experienced workforce for all these tasks.
Well-constructed and properly maintained drains are of crucial importance for the effective drainage of water. We have gained decades of experience in installing various types of drain (collectors and low-depth drains with trench shoring).
A well-constructed road has solid foundations and helps to prevent subsequent subsidence. Our foundations need to be able to withstand the stresses and deformations to which they may be exposed. In this respect, we distinguish between unbound foundations (rubble) and hydraulically bound foundations (sand cement, lean mixed concrete, pozzolan concrete, etc.). We use a sliding formwork machine for larger linear works.
Civil engineering works
Such works include the realisation of all kinds of civil engineering structures such as bridges, road tunnels, bicycle tunnels, noise barriers and pumping stations. We can also handle the realisation or repair of these constructions using our own reinforcement and formwork teams.
In road construction, the reuse of raw materials has become an essential requirement due to environmental and cost considerations. As a result, manufacturers of road construction machinery and road builders have joined forces in order to develop machinery and techniques for recycling the raw materials present in situ. So now, older paving in poor condition can be milled in a single pass by adding the necessary aggregate to the foundations. The new road surface is then levelled and compacted. The result: extremely stable foundations which quickly provide the perfect surface for improved driving comfort, without having to supply or remove raw materials. Applications: rural roads, larger asphalt roads, industrial sites and general foundations.
Besides concrete and asphalt, at Willemen Groep we are just as happy constructing paved surfaces using cobblestones, paving bricks, natural stone slabs, mosaic pebbles or porous materials. For streets, squares or car parks, we have the right laying pattern for the job – fish scale, half-brick, herringbone, English bond, etc. – depending on the surface's application and the chosen materials.
Concrete and asphalt are the two materials most commonly used in road construction, so it should come as no surprise that working with these is one of Willemen Groep's strengths. Concrete works can be used for applications such as bicycle paths, kerbs cast in situ, bumpers, concealed gutters, all kinds of linear elements produced using a sliding formwork machine, etc..
Motorways in continuous reinforced concrete
Our specialities include the (re)construction of motorways in continuous reinforced roadway concrete. For this task, we use the slip form paver which can pour roadway concrete continuously 24/7 so that there are no joints. With a span of 8.5 m, the machine can cover 2 lanes in a single pass. By using this road construction method, we are able to improve driving comfort considerably. This type of paving also has excellent acoustic properties. Our experienced workforce and cutting-edge equipment are what make the difference. Our teams are prepared to work both weekends and nights if necessary in order to complete their project on time.
