Foundation Underpinning Specialist West GTA
We offer underpinning in West GTA, also called foundation reinforcement, for homes where the existing footing needs to be strengthened or taken down to better bearing. This is masonry and concrete work under the foundation, carried out in planned sections so the house stays supported while new concrete is placed beneath the footing.
An Ontario homeowner typically needs underpinning when the foundation is settling. Common signs include stepped cracks in brick, a wall that has dropped or pulled away, sloping floors, doors and windows that suddenly stick, and gaps opening at the base of the house. If masonry repairs or repointing keep failing in the same place, the movement underneath is often the real problem.
Clay soil and freeze-thaw are a poor mix for older, shallower footings. Clay shrinks in a dry summer and swells when it is wet, and frost heave can lift and drop a wall that was never taken down to stable ground. Over time that seasonal movement shows up as settlement, cracked brick and masonry walls, and water getting into joints that were never meant to open.
We assess the foundation on site and work to a proper scope for the conditions we find. We are not structural engineers. Underpinning is done in short, sequential sections under the existing footing, with concrete poured to deepen or reinforce the bearing before the next section is opened. The same method is sometimes used when a basement is being lowered, but our work is the foundation reinforcement itself, not finishing or converting the space.
Once the footing is stable, the wall still needs to shed water. We often follow underpinning with foundation waterproofing and parging so the repaired foundation is sealed and finished, not left as bare concrete against wet clay.
Each project is handled directly by our own masonry team and we are fully licensed and WSIB certified, with all the work we undertake covered by a long-term guarantee. West GTA Masonry has been in the trade for over 30 years. We offer free estimates, 7 days a week, where we can assess the settlement on site and provide you with a no obligation estimate for the underpinning work.
