Now, lowering the floor does not come without its complications. Care must be taken to ensure that the house's foundation is not damaged. That is why, as with all basement renovations, it must be handled by a professional. However, lowering the floor is still something that is commonly done, and there are two main ways to do it.
One way is called underpinning. This involves digging beneath the existing floor and slowly but surely fortifying the existing foundation so that it becomes stronger and is able to continue supporting the house. The advantage of this method is that the floor simply becomes deeper – the floor width remains the same.
Another option, which is usually cheaper, leaves the existing foundation untouched. A new foundation is then poured next to the existing one – a foundation within a foundation, a wall within a wall. This new foundation will then support the new floor. This is known as bench footing. It does take away some floor space, though.
