The Crossing Company was established in 1997 and set out to become the industry leader in Horizontal Directional Drilling. We have combined industry leading personnel with equipment specifically designed for the Canadian climate to complete some of the most challenging projects in Canada.
Please refer to the Heavy Rig Inventory by clicking here.
Our rigs range from 7 - 20 standard oil field loads depending on the size of the rig and the project specific equipment requirements.
The average pad size required for a Crossing Company rig is 40m x 60m with the rig located near the centre of the pad. This pad size is actual work space and does not include the spoils.
Our success rate across all of our divisions is 98.75%
An "Intersect" is a technique in which two rigs, positioned at each end of a crossing, drill towards each other. One rig drills into, or intersects, the pilot hole created by the opposite rig. After the intersect, one rig withdraws from the pilot hole, while the drill string from the opposite rig chases it to other end of the hole. Reaming operations can then be conducted with both rigs working in tandem, or the ream can be conducted in a conventional fashion using one rig only. The product line is pulled in using one rig.
Yes, all heavy rigs work 24 hours a day, seven days a week. There are 5 men per shift and there are two twelve hour shifts per day.
The Crossing Company uses Tensor Steering Tools and Vector Magnetic Steering Tools positioned behind the drill bit in conjunction with Direct Current and Alternating Current electromagnetic coils on surface. The Tensor tool has a stated accuracy of 0.1° Inclination and 0.25° Azimuth. The Vector Steering Tool has a stated accuracy of 0.1° Inclination and 0.4° Azimuth. The stated accuracy of the electromagnetic coils is 2% of the coil to bit vertical distance.
Maximum lengths and hole diameters are determined by project specific geotechnical conditions however effective outside range for horizontal directional drilling is 3,000 m.
Each drilling fluid program is project specific and is designed by a mud engineer. Most systems consist of a bentonite base and have a variety of polymers and additives added to the base system depending on the geotechnical conditions and the desired outcomes.

Depending on the light rig size the number of loads ranges from 3 to 7.
The typical spread sets up on a footprint of 10m wide by 30m long. This includes the drilling rig, support truck, drill stem trailer, and water truck.
With adequate access for large trucks, the rig can be set up and ready to drill in under an hour.
Production rates vary based on the geological formation and size of the product line. It is reasonable to setup, drill and pull in 400m of pipe in one 12 hour shift.
The Crossing Company LRD has successfully completed reams as large as 1067 mm (42") in diameter and lengths up to 900m.
We typically work 12 hours a day, seven days a week.
We have two different types of steering systems, "walkover" and "wire line".
The light rigs use a bentonite based mud system.
Kamloops Augering & Boring Ltd. has equipment and techniques to install casing/pipe from 25 mm (1”) to 3,658 mm (144”).
Crossing lengths are determined by pipe diameter, total crossing length and geotechnical conditions. Typically crossing lengths for these methods are between 10m to 140m.
There is a trenchless construction method for all ground conditions. A comprehensive geotechnical investigation is critical to selecting the right method and managing the associated risks.
Yes a crossing can be completed if the project site has a high water table. Our group of companies has extensive experience constructing shafts, dewatering and managing artesian wells. The dewatering techniques are specific to the trenchless construction method. Water tight shaft construction using steel or concrete, pressurized TBM systems and rotating heads are just a few of the methods employed to manage water.
Using the Guided Boring Machine, we are able complete a crossing up to 120m within 25mm of accuracy at a specific % grade.
Typically, we are able to complete a crossing under an active railway or major highway without any traffic disturbance. Because our techniques never leave a void in the ground there is no safety risk to motorist, railcars, or our crew. Our techniques are only displacing up to 2” of material around the leading edge of the casing, there is little risk of settlement or heaving.
A crossings completion depends on a number of factors including but not limited to: ground conditions, casing size, crossing length, weather, working conditions, line and grade requirements and any unforeseen obstructions encountered. Typically, when planning a project we use a production rate of 12-18 meters per day.
Most trenchless installations require a minimum jacking pit of 11m x 3m plus room for excavators and equipment lay down, however, if a site allows for it, a longer set up site does allow us to install longer sections of pipe which means less welding and a quicker completion of your project.
The cost of a project is all dependent on the crossing length, casing diameter, ground conditions, site location and complexity of the project.
Approximately 2-3 weeks is required to prepare and mobilize a tunneling unit. Each tunneling unit is specifically modified for each project.
The schedule of shaft construction varies based on the size of the project. The shortest amount of time would be 1 week and on larger projects could be 6 weeks.
Tunneling allows for access to the tunneling face itself. Obstacles that can’t be processed by the machine can be dismantled and removed by hand.
Water tight shafts, pressurized tunneling systems and dewatering programs are all different methods of managing groundwater.
Up to a 1,000m is achievable using pipejacking and micro tunneling.
Yes tunneling systems are steerable on the X,Y,Z axis. Steering is impacted by geotechnical conditions and pipe size.
Tunneling accuracy is within +/- 5 cm
A rule of thumb for determining the necessary cover for tunneling is 1.5 times the diameter of the tunnel. For example if the tunnel is 1.2 m in diameter than the recommended amount of cover would be 1.8 m.
Tunneling production rates can be up to 50 m per 24 hours.
Up to 3000 mm is common.
