FREQUENTLY ASKED QUESTIONS

WHAT ARE THE BENEFITS OF CONVERTING A CRAWL SPACE INTO A HABITABLE BASEMENT?

Adding a basement using underpinning is a wise choice, as it allows you to expand your property’s living space and create a comfortable living area, which increases your property’s value while improving the condition of your foundation.

WILL THE HOUSE REMAIN HABITABLE DURING THE EXCAVATION WORK?

Yes, the house remains habitable during excavation work thanks to the installation of fences and secure access ramps. The stairwell leading to the basement is also sealed off to ensure that dust does not make its way up into the living area.

HOW CAN YOU CONVERT A CRAWL SPACE INTO A HABITABLE BASEMENT?

To create a habitable basement from a crawl space, you must excavate the basement and install a underpinning foundation. This involves shoring up the structure, securing the site, excavating in stages, forming and pouring the underpinning, waterproofing and installing the drainage system for the new foundation, and finally, pouring the floor slab.
