Basement excavation & crawl space with foundation underpinning

Our excavation process for basements and crawl spaces uses precision techniques to prepare the ground for construction. Using underpinning methods, we reinforce the existing structure by adding new foundation elements below ground level. This guarantees greater stability and improved resistance to ground movement, ensuring the longevity of your construction.

Structural reinforcement of buildings (opening of load-bearing walls)

Our expertise in structural reinforcement enables us to make significant changes to spaces by opening up load-bearing walls. By incorporating innovative strengthening solutions, we ensure that the structural integrity of the building is maintained, while transforming the space to meet your design needs, without compromising safety or durability.

Stabilization and straightening with piles

The pile technique we use to stabilize and straighten buildings involves inserting long supports into the ground to achieve a stable layer. This method ensures a solid base for the foundation, rectifying subsidence problems and preventing future ground movement. It is ideal for structures that have settled or need to improve their fundamental stability.

Concrete structure (concrete slab and retaining wall)

Our expertise in concrete structures includes the creation of smooth concrete slabs and strong retaining walls. These elements are essential to provide a solid base and stabilize the ground, while offering an attractive aesthetic. We use high-quality materials and proven techniques to ensure the durability and functionality of every project.
