Structural Foundation Repair

Structural Foundation Repair

There are two main types of modern residential foundations – poured concrete and masonry. Both are strong and reliable but either can be subject to movement and damaged caused by pressures in the soil outside them. Harsh Canadian winter causes freezing and expansion of the wet soil and creates side pressure pushing in the basement walls. When exterior pressures exert force on a poured concrete wall, the most common result is cracking. When a masonry wall, most commonly concrete block, is pushed inward by exterior pressures, the damage is usually seen by bowing at or near the center of the wall. To rectify this we install structural beams once the exterior wall has been excavated during the waterproofing process.

Underpinning is the process of strengthening the foundation of an existing building or other structure. Underpinning may be accomplished by extending the footings in depth or width so it either rests on a more supportive soil stratum or distributes its load across a greater area.
