C.T. Soil Group of Companies London Office Services

Geotechnical engineering is a fundamental component of infrastructure and building projects. Our experienced geotechnical team begins with a thorough geotechnical investigation, using the latest in field testing and sophisticated laboratory technology to gather high-quality soil and rock samples to determine the site’s subsurface conditions relevant to the new construction.

Specialty in situ testing equipment include the Marchetti-type flat plate dilatometer (DMT) to obtain near-continuous empirical correlations for such soil properties as material type; undrained shear strength, angle of internal friction, over consolidation ratio, and horizontal subgrade modulus among other geotechnical engineering parameters.

​

The lab methodologies are carried out at our head office in Windsor, Ontario and we are certified by the Canadian Council of Independent Laboratories (CCIL). 

Some of the specialty services provided by our teams include geotechnical subsurface investigations, structure foundations including deep foundations, shallow foundations, testing, supervision, and review.

We are a laboratory that is a CCIL member accredited in accordance with ISO (International Organization of Standards).

The geotechnical and construction materials division represents the interests of testing and geotechnical consulting engineering. We offer a broad range of services for materials such as:​

• Soil and backfill
• Rock

• Inspection and field services
• Forensic engineering investigations

Our environmental team prides themselves on delivering solutions, not just a service. Our team has the technical expertise and experience needed to deliver your project from due diligence to large scale redevelopments. Our team provides: Phase I Environmental Site Assessment (ESA), Phase II ESA, Record of Site Conditions (RSC’s), and chemical analysis.

The purpose of a Phase I ESA is to identify actual and potential site contamination. This involves the evaluation and reporting of existing information collected through Records Review, Site Visit, and Interviews. Phase I ESA may assist in reducing uncertainty about potential environmental liabilities and may be a basis for further investigation of the property.

​

The purpose of a Phase II ESA is usually to confirm and delineate, or to demonstrate the absence of, contamination on a property identified through the Phase I ESA procedure. In some cases, a Phase II ESA may be undertaken to establish a quantitative baseline for environmental conditions at a site. Phase II investigations are undertaken prior to remedial and/or delineation investigation

​

We also prepare ESA’s in support of filling a Record of Site Condition (RSC), which are often prepared if you are thinking of changing the use of a property you own.
