In the past, many homes were built without a full height basement. Also called “crawl space”, this type of construction lets in a lot of moisture doesn’t allow to maximize the use of the basement. It is possible to excavate the basement without lifting the house and build foundations by underpinning, that is to say, under the existing foundations.
With this type of work, homeowners can benefit from full height basements with proper humidity control. Work is performed from inside where excavation and formwork are executed by steps to maintain the stability of the structure above. With new interior drainage, proper insulation and a concrete slab floor, this improvement can significantly grow living space. In this context, it is also possible to construct an outside access to the basement and even an English court to take full advantage of this new space.
