Why underpinning?
Underpinning is a two-fold winner. First, it creates added height to your existing foundation, which in turn adds 100% usable living space to your basement. This procedure is usually done with basements that do not have enough headroom to navigate around. Second, underpinning adds positive value to your existing home, also giving your home an added selling feature for re-sale.
