Exterior Drain Tile was improperly installed in this basement, there was no gravel cover and it clogged. Once the gravel was properly installed and joints waterproofed, it became a perfectly dry, safe and healthy basement.
Water build-up on the exterior of this basement wall caused a leak at the point where the sewer pipe penetrates the wall. The pipe was not sealed thoroughly and well, and the correct fix includes removal of dirt on the exterior, sealing the pipe on both; exterior and interior, replacing and adding gravel over the drain tile, and re-installing the landscaping exactly as it was, using as reference the photos taken before the excavation.
Water can come into a Basement around the water supply pipe, during and after a rain. An inexperienced repair contractor will think the drain tile in the basement is clogged, but most of the time, water is traveling via the corrugated sleeve protecting the pipe from the street level to the basement. It was never plugged and sealed at both ends. This problem when mis-diagnosed, has caused many home-owners large and unnecessary expenses.
Seismic plating, will restore and even increase the structural integrity of a damaged basement wall while making it water tight, as is the case with this wall 19 years later.
We often perform repairs which require special fabrications. It is possible to restore the structural integrity of a wall by incorporating a fabricated part of high strength steel or carbon fiber. Special fabrications are engineered and done in-house.
Extensive restoration was performed to St. Stephen Martyr Church’s Foundation. All deteriorated materials were replaced. Water leaks stopped, and pump equipment installed. All work was performed from the interior of the Church, and the structural integrity of the foundation was restored. Repairs to structural failures in Historical Buildings is one of our strengths.
When restoring a foundation, our mission is: go directly to the root of the problem, that includes removing all patches, quick fixes and cover-ups.

With a system of underpinning we provide support to load-bearing walls and columns as can be seen on this Historic Mansion. Using varied methods, we have repaired and restored many foundations, some of them in delicate and difficult situations.
All surfaces are washed. Through our dust extraction procedure debris and humidity are removed from the crack, allowing optimum bonding of the epoxy to the concrete when it is injected through the ports.
Steel straps are added when additional stability is needed and to minimize concrete shrinkage.
