  • Geotechnical Drilling

    Geotechnical Drilling and sampling of soils and bedrock provides information about the formation and stability characteristics vital to the construction industry. By studying these characteristics along with ground water and bedrock mapping it allows the process of construction to be carried out in the best manner with no surprises.

    A 2′ split spoon is the most effective method of retrieving a sample of soil, though use of a sand trap is needed in sand formations and shelby tubes are used to extract soft clays with little or no SPT value. When rock coring, an inner tube, seated at the bottom of the drill string is extracted to obtain the core sample needed.

    Standard penetration testing (SPT) is done with the use of our automatic hammer, which drives a split spoon or a dynamic cone point(cone penetration testing) into the soil at a certain drop rate and weight. The amount of times driven into the soil within certain measurements provides the data needed to calculate soil strength. Shear tests are done with field veins in soft clays to determine shear strength if low SPT value is shown. These are standard tests in geotechnical drilling. Determination Drilling is equipped with all of these tools to sample, on our rigs for any geology we encounter.

  • Environmental Drilling

    Environmental drilling & sampling is generally done for phase II and phase III environmental assessments of commercial, government, and residential properties. By drilling through the soils and/or through the desired water table(s), environmental investigations of the soil and water can be done to determine the presence and/or concentration of contaminants in the water table. When all of the environmental drilling is completed to depth, we are then able to install 1″- 2″ monitoring wells through our hollow stem augers (3 1/4″, 4 1/4″ID) into the water tables of soil.


    The use of rock coring or triconing are our methods for bedrock monitoring well installations to the desired depths. Cluster well installation is the process of situating multiple wells in the same borehole. This is used to capture different water tables for further investigations.

    Our employees are licenced well technicians, by the Ministry of Environment and are educated on the importance of sealing each monitoring well properly, in accordance to Ontario’s regulations (Reg.903).

  • Exploration Drilling

    Rock coring is the use of a diamond encrusted drill bit to drill through the bedrock. With high speed rotation and water as a flushing agent, as well as to cool the bit, the drill produces a core sample which then is extracted from depth, for examination. Geological site investigation is common in any area for studies of the Earth’s formation or fractures in the earths rock layers. We also perform Environmental Site assessments by installing monitoring wells in the bedrock for future studies for water tables.

    Exploration diamond drilling is used in the mining industry to probe the contents of known ore deposits and potential sites. By withdrawing a small diameter core of rock from the ore body, geologists can analyze the core by chemical assay and conduct petrologic and mineralogic studies of the rock.

    Determination Drilling has been a part of geological / exploration drilling in such mine sites as DeBeers’ – Victor Mine, Attawapiskat, Ontario, Noront – Ring of Fire Project, North Western Ontario, and Iron Ore Company of Canada’s – Labrador Mine, Labrador City, Newfoundland all on multiple occasions.
    Our drill rigs are capable of rock coring with BQ, NQ or HQ rod sizes to drill to get to desired depth extracting all bedrock samples.Iron ore, kimberlite, granite, and quartz are examples of some harder rock we are able core through as well as retrieving softer types of rock such as limestone or shale.

    Give us a call to discuss your project requirements and we’ll provide you with effective drilling & logistical solutions to make your drilling program a success!

  • Water Well Drilling

    DDSI is a steward to the environment.  As a licenced water well contractor we serve the residential, industrial, and agricultural communities by drilling irrigation, dewatering, and drinking water wells. It is critical for people to have clean drinking water that is safe and tested. It is equally important for farmers to have water sources for livestock, and/or crops to survive. Dewatering wells are important for construction projects, as excavating large areas of land can be more effective if the ground water is temporarily removed.

    Whatever the application is, we will ensure that your ground water needs are completed in accordance with OReg 903 to protect the worlds most precious resource for generations to come.

  • Decommissioning

    Well abandonment is a great practice to get into for both environmental, and safety reasons.  If you own a property, or know of any wells which are not in use, they provide a conduit for contamination to affect an aquifer which entire communities may rely on.  These should be capped as per OReg 903, and DDSI has the knowledge and licences to take care of this for you.  Some regions actually have financial incentive programs through the local conservation authority to assist you with the cost of abandoning these old wells.  For more information, or to do your part for our environment, please contact us today!

  • In Situ Remediation

    In situ remediation is the use of microorganism metabolism, called bioremediators, to remove pollutants from underneath the ground. Determination Drilling offers in situ bioremediation by use of drilling and treating the contaminated material on site. Methods for these injections can be done with the use of our augers, our probe rods, and even through monitoring wells.

    When augering, the borehole is drilled to the targeted depth of contamination, the augers are retracted to the amount desired for injection (usually 5′ – 10′) and the packer system is lowered in our 3.25″ augers. With the use of our packer system we are able to push bioremediators through our augers in the specific zones allowing for an effective injection.

    With the use of our direct push technology, injections can be made through a probing rod, once you have reached the contaminated zone. The slots in the rods allow the bioremediators to pass into the soil, injecting with minimum disturbance to the ground.

    Injections can also be successfully completed through a finished monitoring well. Once a monitoring well is installed with the desired amount of screen, injections can be done through the top with a fitted cap.

  • Barge Drilling

    Determination Drilling can drill off shore, as well, with all of our drills. With multiple barge drilling jobs accomplished, we find that drilling off shore is second nature. We are able to auger/washbore and split spoon sample in sediments and utilize rock coring and retrieve core samples in any marine environment.We have had all of our drilling units on a variety of different barge designs, for many major geotechnical projects.

    On barge drilling safety and environmental protection is paramount at all times, through the use of safety devices such as guardrails, flotation devices, secondary containment and environmentally friendly hydraulic fluid, we are outfitted for the drilling in an aquatic environment .

  • Dam Drilling

    Determination Drilling has performed geotechnical drilling for safety assessments on over 100 earth wall, and concrete structure dams throughout Canada.   We have specialized equipment and techniques to adequately assess concrete structures to ensure their competency, and to see if they are bonded to the bedrock.  Our flyweight prospector drill is compact & light weight which will not put additional stress on the structure.

    We employ diamond core drilling as our main drilling method which is a rotary abrasive downhole technique, again not adding any percussive energy to the structure.  After the core hole is completed, we typically lower a downhole camera into the hole to view the outside of the borehole wall, identify any cracks/fissures, find the height of the water table, look to see if the concrete is bonded to the bedrock interface, and to see the condition of the bedrock beneath.  We then perform packer testing in the bedrock formation below to determine permeability.  If a gap is identified between the bedrock, and the concrete structure, we are able to lower steel rods into the hole, and pressure grout the structure to add strength, and increase longevity.

    While working over the water, special environmental and safety protocols are put into place to ensure that the water below is not affected by our activities, and all personnel are protected from any new hazards associated with working over water.  DDSI is the premier drilling contractor in Canada when it comes to dam drilling, and we encourage you to contact us for your next dam drilling project…our experience will ensure your project becomes a success.

  • Heliportable Drilling

    Determination Drilling can dis-assemble and re-assemble our drilling rigs to adapt for heliportable requirements, when drilling in remote places is needed. We are able to break our drills down into 3-4 pieces for helicopter flight and assemble them at the next drilling location. Our crew has helicopter training for safely loading and unloading the slings of equipment and supplies, and we are educated and comfortable using the proper hand signals to communicate with the helicopter pilot.

    Heliportable drilling is always an adventure, being helicoptered out into some of the most remote places on the planet and drilling our boreholes is simply amazing.  Our crews are capable of drilling in any location through soil or bedrock on these types of jobs, whether we have to use fallen trees as our drilling base, battle trillions of mosquitos/blackflies, or running hoses kilometers away to be able to find a water source for coring. No matter what the challenge may be, Determination Drilling will find a solution to get the job done safely and effectively.
