MTO Scugog River Bridge
Date: 2009 View Case Study
In contemplating foundation options for the twinning of Highway 7 over the Scugog River, Ontario's Ministry of Transport (MTO) had for years struggled with a dilemma: shallow foundations, that would not jeopardize the existing bridge footings, would not suffice to meet stringent new design codes (particularly with respect to scour), and a conventional deep foundation, while meeting code, would almost certainly disturb or damage the existing structure.

Stirling Road, Toronto - Environmental Remediation
Date: 2010 View Case Study
A former electrical sub-station in the Junction District of West Toronto underwent site remediation for PCB and hydrocarbon contamination in order to permit re-development. The Remediation Plan called for installation of a braced interlocking (secant) caisson wall excavation support system around the site perimeter, followed by excavation of contaminated soils to a depth of 6 m below grade. In the course of identifying and removing abandoned subsurface utilities prior to caisson drilling, the remediation contractor, Priestly Demolition Inc. (PDI) discovered a live electrical duct bank within the site footprint. The duct bank serviced an adjacent heritage building and could not be taken out of service or relocated. The caisson wall alignment had to be modified to avoid damaging the duct bank thus leaving a zone of contaminated soil below the duct bank. In order to satisfy Ontario Ministry of Environment requirements, an alternative means of remediating this contaminated zone was required. More »
Environmental Remediation Site
Date: 2008 View Case Study
Geo-Foundations constructed a set of jet grouted soil-cement columns to form a portion of an environmental barrier wall at a large remediation project in Toronto in 2008.

Niagara Tunnel - Intake Shaft Grout Curtain
Date: 2007 View Case Study
Ongoing strong demand for clean, renewable electricity in Ontario, Canada resulted in the creation of the Niagara Tunnel Project. Due to be commissioned in 2013, the new 10.4 kilometre long, 14-metre diameter Niagara Tunnel was built with the help of the world's largest hard rock tunnel boring machine, "Big Becky". The tunnel was advanced from downstream to upstream. When Big Becky broke through in 2010 into the tunnel's 45-metre deep intake shaft in the middle of the river just upstream from Niagara Falls, conditions were suitably dry for its safe dismantling and extraction thanks to the presence of a grout curtain designed and constructed in 2007 by Geo-Foundations.

Remediation of disturbed foundation bearing soils, Toronto
Date: 2009 View Case Study
When the perimeter spread footing of a 1970's era mid-rise located in midtown Toronto were undermined by a neighbour's deep excavation, the options for remediation came down to micropiles or compaction grouting. Due to the cohesionless character of the foundation soils (compaction grouting works best in self-draining soils) and the relatively shallow zone of disturbance, compaction grouting was chosen for its expeditiousness and cost effectiveness, and Geo-Foundations was selected to carry out the compaction grouting on a unit rate contract basis.

Laneway Remediation, Toronto
Date: 2007 View Case Study
Toronto's news media outlets were abuzz one afternoon in the summer of 2006 after a garbage truck was partially swallowed by a large sinkhole that developed in a back alley laneway in midtown Toronto. The laneway dates to the 19th century and in the weeks following the drama, investigations determined that the sinkhole was caused by a combination of poor initial construction, layers of organic soils underlying the surface paving and, most predominantly, a leaky sewer.

Jane Street & Highway 7
Date: 2006 View Case Study
The intersection of Jane & Highway 7 in Vaughan was closed from February to May of 2006 after a manhole within the intersection collapsed and caused a water main to break.

9th Line Trunk Sewer
Date: 2006 View Case Study
During the jack-and-bore excavation of a tunnel beneath an existing railway, extremely challenging soil and groundwater conditions led to the over-excavation of soil. Several months after the sewer tunnel had been constructed, subsidence of the rails was detected. After more months of monitoring the settlement, it was determined that remedial intervention measures would have to be undertaken to arrest the settlement. Compaction grouting was chosen as the method best suited to affecting the desired improvement while accommodating ongoing daily passenger rail service. More »
