GEOTECHNICAL DRILLING SERVICES AND PROJECT LIST Cascade offers a wide variety of drilling technologies to ensure your project is completed right the first time, regardless of lithology. Our geotechnical drilling teams offers the following services: Piezometer and Inclinometer Installation
Cascade has the equipment and experienced personnel to install piezometer and inclinometer casing in almost any circumstances.
Cascade has attracted and trained some of the best drill crews in the industry. Our goal is to make your job easier and to save you time and money. We meet our goal by listening to your needs and by paying strict attention to safety, logistics and the quality of our work. We stress communication, teamwork, and technical skills. Our crews are motivated, enthusiastic, and take pride in their work. Cascade's preparedness and high productivity reduce on-site time and saves you money. In order to boost productivity, we operate a broad range of well maintained, late model equipment operated by experienced, cooperative crews. Our drillers are licensed to drill and install wells in the states of Oregon, Washington, California, Nevada, Arizona, and Idaho. Our personnel are continuously trained on the job and in shop training sessions by our Operations Management and by our senior drillers. Mud Rotary/Hollow Stem Auger Technical Information
Conductor casing up to 9" diameter can be set up to 50 feet deep by using 10" ID x 15" OD augers. Monitoring wells may then be set. The rigs are also equipped with asphalt "cookie cutter"and concrete "bull dog" bits for drilling on developed property.
Our HQ and NQ wireline Triple Tube coring systems with casing advancer ensure efficient and reliable core drilling. The wireline casing advancer also provides an efficient one step method of drilling through overburden and casing off to bedrock.
Cascade Drilling, Inc. has equipped its two late model Ingersoll Rand T3W to be as versatile as possible. The T3W is set up to drill with augers, air rotary and drive casing, or air rotary with ODEX and is operated by a three man crew. Air rotary drilling is ideal for extremely drifficult subsurface conditions such as large cobbles, boulders, and landslide debris where traditional mud rotary or hollow stem auger drilling is not feasible
Other Services
Selected Geotechnical Project Experience Cascade Drilling Inc. has performed hundreds of projects for foundation and soil investigations. Below is a short list of projects we have performed which required geotechnical drilling services. • GeoEngineers, Gas Pipeline, Oregon Description: Completion of twenty borings located at eight remote project sites along proposed pipeline. Both a CME 75 and a 850 ATV track rig were used to gain access to remote drilling locations. A total of 600' of auger drilling & 450' of HQ-3 rock coring was completed within 10-days. Project was completed under budget & ahead of schedule with a 3-man crew • Geotechnical Resources, Inc., Clark County Landslide, WA Description: CME 850 Track Rig was used to drill through landslide debris and install inclinometer casing up to 70' deep. Concurrent with drilling activities, Cascade Drilling provided a bulldozer to bench in a landing for the drill rig. Three inclinometers and four observation standpipes were installed. Pneumatic piezometer instrumentation was also installed in all of the completed inclinometers. • SECOR Inter., Inc., Clackamas, OR Description: Air rotary ODEX drilling to install several Waterloo multilevel groundwater monitoring systems within alluvial gravels. Multilevel systems were used to obtain hydrologic data from various elevations within a single borehole. Complex instrumentation clusters were installed in wells. • David J Newton Assoc., Clackamas County Quarry Sites, OR Description: Provided rock coring services at three basalt quarry sites in Clackamas County. Highly weathered overburden conditions were encountered. Cascade Drilling used both HQ and NQ wireline triple tube coring systems to ensure high recovery rates. Within competent rock formations, a 10-foot long NQ core barrel was used to provide efficient wireline coring. Project was completed ahead of schedule. • Landau Assoicates, Sand & Gravel Facility, Oregon Description: Over-water barge work with limited access drill rig. Completed sediment sampling in settling ponds to depths of 40 feet. Cascade used a continuous sampling system with 5-foot long core barrels (3 1/4" ID sampler) to provide sufficient sample volume for sediment analysis. The continuous sampling system used provided sample orientation & directional trends of fractures in extremely soft soils. • Slope Indictor Inc., Bothell Property, WA Description: Hollow stem auger drilling through till and debris to install four inclinometers to depths of 60-feet. • Confidential client, Elliot Bay- Barge Drilling Description: Over-water barge work drilling with hollow stem auger. Completed soil borings to 96-feet depth into bay sediments. Work was completed over 50-feet of open water.

Cascade
Drilling, Inc. has converted its late model CME 75 auger rigs
to a high torque configuration to obtain 22,000 foot pounds of
torque; nearly twice the torque of a Mobile B61. The 75's are
capable of drilling to 200' with 8" diameter hole. Several rigs
are equipped for angle holes up to 45 degrees off of vertical.
The CME 75's are truck mounted with a Nodwell tracked vehicle
mounting available for access on soft ground. Additionally, our
all terrain CME 75 track rig is capable of remote site access
for mud rotary, auger and coring.
