Rooms Under Existing Homes

| Avalon builds waterproof rooms under existing homes. The following two photos show a before and after. Along the wall on the right, Avalon employed shoring techniques that allowed the new retaining wall below to align flush with the existing stem wall above.

| We can put a basement under an existing house. In this example, we installed four 3.5" diameter round shaft helix piers to support the interior of a two-story one hundred year-old Victorian, then excavated around the helix piers. These heavy duty helix piers have ample lateral strength to stand without lateral soil support.
