Album of our projectsLiving rooms, kitchens, bathrooms, facades and moreIn brief
MS Contractor SA carries out underpinning in Avusy for houses and buildings. Strengthening or deepening of foundations with pads, micropiles or ground beams, reworking of load-bearing walls, relieving beams for an opening, crack injection and propping are carried out according to the engineer’s calculation.
The context in Avusy
Several hamlets scattered across farmland make up this border municipality of the Champagne genevoise, known for its gravel extraction. Farms, village houses and villas make up most of the buildings. As the centre of the canton is far away and the agricultural zones are protected, projects mainly concern existing buildings.
Foundations and settlement in Avusy
Deepening of foundations in alternating passes, micropiles or ground beams, after a study of the ground and the causes of the settlement.
Cracks are monitored before and after.
Load-bearing walls and openings
Steel or concrete relieving beams to open a load-bearing wall, reworking of older masonry, propping during the work.
The engineer’s calculation comes before each job.
Cellars and basements
Creating a basement or deepening a cellar, tanking and drainage to keep the space dry.
Adjoining neighbours are informed.

Frequently asked questions
Your questions in Avusy
How long does underpinning in Avusy take?
Two to six weeks depending on the length of wall to rework and the method. The quote details the items and the planned duration and specifies what is not included.
Is a permit needed for underpinning in Avusy?
A reworking that does not change the volume of the building counts as maintenance, but an engineer’s calculation is essential. A new basement requires a permit that we prepare with you. The details of the procedures are on the website of the State of Geneva, on the applying for a building permit page.
Can you live in the house during the work in Avusy?
Yes, in most cases, the work is done from the outside or from the basement, in small propped passes.
How can you tell whether a crack needs attention in Avusy?
A crack that widens, goes through the wall or comes with a sloping floor calls for an opinion. We install monitoring markers and bring in the engineer.
