For the last couple of years Basement Lowering has become a popular renovation project in Toronto and GTA due to the low overhead height in the basement of many existing homes (~6-6.5 feet).
By extending this height to 8 feet through the downward extension of the foundation walls, extra space becomes available as a source for additional income from basement apartment for rent or extra living space for your family.
Benching or Bench-Ledging
A stable soil slope is maintained between the lowered basement floor level, and the underside of the original footings (to avoid undermining the footings). Then, a steel reinforced concrete "bench" is poured over top of the stable soil slope, to ensure that the soil slope is protected. It leaves you with a concrete bench around the interior perimeter of the basement.
A sequence of holes are dug-out from under the footing of your home.
The footing is the concrete or brick pad which spreads the load of the foundation walls onto the soil. Typically, a series of 4' wide holes, separated by 8' of undisturbed soil, is prepared and filled with concrete. The top 2" of the concrete filled hole is packed with non-shrink grout, rather than filled to the top with concrete, so as to avoid the possibility that air pockets are present. Once the first series of holes are filled with concrete, the adjacent 4' wide segment is dug-out, and the underpinning process continues.
