Create Space with Basement Lowering / Underpinning
Basement lowering and underpinning of Windsor area homes is usually required to create additional living space. In some of the older homes, basements have lower ceilings and are primarily used as a utility space. However, with the proper engineering, construction, and waterproofing technology, we convert these types of basements into livable space, by lowering the basement floor and waterproofing the foundation. This is usually done by foundation underpinning, benching and helical piles.

Which One? – Underpinning, benching, and helical piles are three distinct methods used to stabilize, repair, or deepen building foundations. Traditional underpinning extends the existing foundation straight down with concrete, benching pours a supportive interior concrete ledge without deep excavation, and helical piles use driven steel screw shafts to reach load-bearing soil.
If you’re lowering your basement floor to create additional headroom, underpinning is typically required to strengthen and extend the existing foundation. If traditional underpinning is not practical due to soil conditions, structural concerns, or cost, benching can provide a safe and effective alternative. If your home is experiencing settlement, foundation movement, or is built on unstable soil, helical piles offer deep structural support to stabilize the foundation.
