Underpinning basement excavation
Is it possible to expand a basement without moving out?
Yes, it is possible to expand a basement without moving out, using methods such as underpinning excavation. This technique allows you to increase basement height or space while keeping the house in place. The work is done in stages to maintain safety, access, and minimal comfort for occupants.
Key conditions for staying in your home during the project include:
- Gradual, section-by-section excavation: to keep the structure stable at all times.
- Access management: ensuring some parts of the home remain usable.
- Temporary service disconnections: managed to reduce disruption (plumbing, electricity).
- Safety barriers and dust control zones: to contain noise, debris, and hazards.
While staying is often possible, temporary relocation may be recommended depending on project scope. For a complete evaluation, contact Heneault Gosselin.
