How your project runs
Each project starts with an on-site visit in Thônex to assess the work precisely. You then receive a detailed offer, item by item, then the work is carried out on the agreed dates, with a single contact from start to finish.
Thônex, structural work for older houses and residential plots
Creating an opening in Thônex means knowing the type of walls and the role of the floors. The project studies specify the reinforcements and supports needed before the work. The survey of what is in place also identifies earlier transformations to take into account.
A garage slab, an extension, a wall or the foundations of an annex call for work prepared according to the ground. We examine the possible access for machinery and deliveries. The studies and protection needed for neighbouring structures are specified before the worksite.
Do you need an engineer to open a stone wall?
Yes, as soon as the wall is load-bearing. The engineer sizes the lintel and the propping according to the loads coming down from the upper floors. On older masonry, they also specify how to rework the stones around the opening.
