The Right Drilling Equipment for Your Project
Cascade Drilling owns and operates a large, and growing, fleet of well-maintained, late-model equipment to accommodate many
environmental drilling and
geotechnical drilling projects at a time. When selecting the right equipment for your project, our crews not only assess your drilling needs, but also terrain, location, and lithology. The equipment that gets transported to your site will be exactly what is needed to get the job done in the most efficient method. Our large fleet allows our teams to be flexible enough to change equipment in the field to better serve your interests.

Drilling Techniques
Cascade Drilling uses a variety of drilling techniques. When we select the right technique for your project, we'll explain in detail why it's the most cost-effective and efficient method to use.
^ top
USE: Highly efficient if your project requires boreholes through consolidated bedrock formations.
Air rotary bits are cooled during cutting by injection of high-flow air, which also evacuates rock cuttings from the borehole and stabilizes the borehole while drilling. The high-flow air constantly cleans the bottom of the borehole, which allows for consistent contact between drill bit and bedrock. Foam can be added to the injected air to increase viscosity in boreholes where lifting the cuttings is difficult.
Our rigs' air compressors are double filtered to remove residual oil. Sampling is accomplished with a 140 pound Mobil safety driver which is lowered down the hole on a wireline. The sampler is driven by a free fall winch and retrieved, saving time over the drill rod method. The sampler may be attached to drill rods if necessary.
Air rotary rigs are equipped to do air rotary casing hammer, air rotary under-ream, mud rotary wireline coring, or sampling through the drill rods.
Drilling deeper holes in unconsolidated formations is accomplished with the drill and drive method. The casing is advanced by an Aardvark hammer which swings out for ease of sampling and well installation. Cascade has 13", 12", 10", and 7" OD threaded casing in 5' and 10' lengths to allow for various sampling intervals. ODEX Underreamer systems are used when drill and drive is not possible due to large boulders or bedrock.
^ top
USE: Less intrusive and much faster when your project requires gathering huge amounts of soil and groundwater data on the properties and conditions of soil and groundwater in unconsolidated formations.
Instead of a rotating auger, direct push rigs use a hydraulic hammer to create a borehole. Your project can progress quickly because, in the right soils, direct push can produce many high-quality samples rapidly, often as fast as 150 to 300 feet per day. Direct push can be combined with sonic drilling to increase efficiency.
^ top
USE: Best if your project requires shallow boreholes in unconsolidated formations. Useful when taking soil samples and/or advancing the borehole for large diameter well installation.
A pilot bit is inserted through the cutter head to drill the center of the hole. By bolting the drill rod to the inside of the drive cap with a rod-to-cap adapter, the pilot bit can turn in tandem with the augers. We use this method when your project requires leaving the augers in place while also sampling or rock coring.
We've converted all of our late model CME 75 auger rigs to obtain 22,000 foot pounds of torque; nearly twice the torque of a Mobile B61. Several rigs are capable of drilling to 200' with 8" diameter hole. One rig is equipped for angle holes up to 45 degrees off vertical. The CME 75's are truck mounted with a Nodwell tracked-vehicle-mounting for access on soft ground.
^ top
USE: Ideal if your project requires advancing deep boreholes in unconsolidated formations.
The drill bit is cooled and lubricated by drilling mud, which also carries the cuttings to the surface. Drilling mud cleans the bottom of the borehole, creates an impermeable bore surface, overcomes formation fluid pressures, and prevents collapse of the borehole. Productive water zones are protected, the drill pipe won't corrode, and electric well logs can be obtained.
^ top
USE: Best if your project requires continuous, undisturbed core sampling through most types of geological formation.
Sonic drilling has so many advantages to recommend. It's a low-impact technology that is safe and clean. By rotating and vibrating the rod, casing, and core barrel at sonic frequencies, a clean borehole is drilled, cored, and cased at one time. A great deal less cuttings are generated, saving time and cleanup. Support equipment includes hydraulic rod spinners, threaded casing from 5” to 12”, support trucks with cranes, water tanks, etc.
