COMPREHENSIVE HDD AND TUNNELING SERVICES
The Crossing Group provides a full range of trenchless construction services to pipeline, utility and construction clients in Canada and the United States.
HORIZONTAL DIRECTIONAL DRILLING (HDD)
Horizontal Directional Drilling is an accurate and efficient trenchless solution that utilizes steerable drilling technology. Our extensive fleet of heavy and light HDD rigs allow us to install pipe and product lines over great distances up to 3,000 m (9,843 ft) without the need for continuous excavation.
AUGER BORING & PIPE RAMMING
Tunneling is used for crossings of shorter length, and is suited for large diameter installations. We offer a wide range of tunneling services and will recommend the one that is right for your project and ground conditions.
DIRECT PIPE® INSTALLATION
Direct Pipe® provides a one-pass installation solution with a high degree of steering accuracy. Our team is experienced in operating Direct Pipe® equipment and offers prefabricated pipeline installations to clients throughout North America.
MICROTUNNELING
Microtunneling is often used to complete crossings beneath rivers, wetlands, railroads, harbours, and highways because of its precision and ability to manage difficult ground conditions. Our MTBMs are especially effective for pipelines that require a high degree of precision over long distances.
There are a number of factors that come into play when choosing a trenchless solution. We’ve developed the following chart as a rough guide. For an accurate, professional assessment, please contact a Crossing Group company.
- Crossing Length
- Product Line Diameter
- Soil/Formation Type
- Required Precision (Alignment and Grade)
- Product Line/Casing Material (eg. Steel vs Polymer)
