Overpour Underpinning

This is the newest form of underpinning where the new concrete reinforcement is overflows out and above the bottom of the existing foundation. This is the most efficient method. Due to the nature of the new foundation reinforcement overlapping the existing, the new wall does come out approx. 3-4”.  

Dry-pack Underpinning

This is the best practice underpinning where the new concrete reinforcement is poured to approx. 2-3” below the underside of your existing footing. Once that concrete settles (typically 48 hours) the 2-3” void is packed with non shrink grout. This ensures a solid bond between the concrete reinforcement and the underside of the existing footing.

Bench footings

At times when underpinning is not possible (often partition walls or neighbouring foundations are too close) then our team can execute a bench footing. This is the least intrusive method as there is no undermining of the existing foundation. Depending on conditions the soil is either excavated flush with the existing wall or sloped from the wall. While this method is typically least intrusive and most budget friendly. It does result in lost space due to the bench style of footing that is left
