Tri-Phase’s Drilling Division is equipped with track and truck mounted drill rigs to handle any geotechnical project.  These rigs run both solid stem and hollow stem augers, all automatic drop hammers and concrete coring systems.  All our rigs are equipped with auger guards and other safety equipment in compliance with current regulations.  We are a licensed Well Contractor and all our drillers are licensed Well Technicians.  Our technicians have also successfully completed Petroleum Oriented Safety Training (POST) training and have WHMIS, First Aid and CPR and Confined Space Entry training at a minimum.  Our technicians have over 20 years of experience working in the Greater Toronto Area and can tailor their approach and drilling method to meet your specific project needs.  Whether you require drilling to collect soil or water samples, rock cores, to advance in-situ sampling equipment or to install monitoring wells or piezometers, we have the technicians, equipment and experience to complete your projects safely and efficiently.


Whether the area you have to assess for contamination is outdoors in a paved parking lot, or rough terrain,  or a landscaped area or indoors in a basement with limited access and clearance, we have the equipment required to obtain any soil and groundwater samples you may need.  All our rigs come equipped with 140lb auto-drop hammers and the latest safety equipment which allow for easy and efficient operation.  Our technicians are also well versed in the installation of groundwater monitoring wells and remediation wells for the treatment of groundwater.  They employ several drilling methods based on geologic conditions and the type of testing to be performed.  Furthermore, Tri-Phase holds a Certificate of Approval (C of A) from the Ontario Ministry of Environment (MOE) that allows us to dispose of any contaminated waste generated from the drilling process at a licensed disposal facility.

Chemical Injection

Tri-Phase employs several remedial methods and chemical injection for contaminated soil and groundwater is one such method whereby a powerful reagent is introduced directly into the ground to break down the harmful contaminants.  The primary delivery mechanism for this type of remedial method is through perforated, hollow metal rods hammered into the ground by direct push drilling methods or by injection of the reagent into wells installed using hollow stem auger drilling. This method can be particularly useful when excavation of contamination is not an option.  Chemical injection is typically less costly than traditional remedial methods such as excavation and disposal; however, it requires more time as well as an experienced contractor.  Tri-Phase has both the theoretical and practical knowledge to tackle your contamination problem in a safe and effective manner.
