Frequently asked questions
Your questions in Troinex
How long does underpinning in Troinex take?
Two to six weeks depending on the length of wall to rework and the method. In the quote, you will find each item, the planned duration and what is not included.
Is a permit needed for underpinning in Troinex?
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 Troinex?
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 Troinex?
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.
