HDD


Horizontal Directional Drilling (HDD) is a steerable trenchless method of installing underground pipes, conduits and cables in a pre-determined and designed arc, also called the bore path. The drilling is done by a drill rig, set-up on the surface, and stabilized to know exactly where the drill bit is at all times. The method has minimal impact on the surrounding area.

HDD is used when trenching or excavating is not practical. It is suitable for a variety of soil and rock conditions and for crossing such features as roads, water bodies, wetlands or other sensitive landscapes and congested urban settings. HDD minimizes environmental disruption.

HDD installations are generally accomplished in three stages. The first stage consists of drilling a small diameter pilot hole along the designed bore path. The second stage involves enlarging the pilot hole to a diameter sufficient and suitable for installation of the pipe. The final stage consists of pulling the pipe into the enlarged hole.


The HDD drilling rig has an inclined ramp instead of a vertical mast that oil/gas well drilling rigs have. Because of the similarities to oil/gas well drilling (drill pipe, interchangeable down hole tools, use of drilling mud, etc.), the process is referred to as drilling as opposed to boring.


HDD is used for installing infrastructure such as telecommunications and power cable conduits, water and sewer lines, gas and oil lines, product pipelines and environmental remediation casings. It is used for crossing waterways, roadways, shore approaches, congested areas, environmentally sensitive areas, and areas where other methods are costlier.

HDD is preferred over other methods for minimal traffic disruption, lower cost, deeper and/or longer installations, no access pit, shorter duration times, directional capabilities, and most importantly, environmental safety.

Horizontal Directional Drilling (HDD) is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface launched drilling rig, with minimal impact on the surrounding area. HDD is used when trenching or excavating is not practical. HDD minimizes environmental disruption. It is suitable for a variety of soil conditions and jobs including road, landscape and river crossings.

Direct Pipe® Drilling



Direct Pipe® Drilling
is a method that installs pipelines in a one step process. To date, Direct Pipe® Drilling is the most accurate installation method and is extremely useful in areas that contain underground utilities.


Direct Pipe® Drilling is performed at a faster rate than conventional tunneling and is often the only option for marine crossings. This method is recognized for handling a variety of challenging soil conditions, including cobble and gravel.

Direct Pipe® Drilling is performed by using a cutter head to bore a hole that is marginally larger than the pipeline. This head is interchangeable to adapt to unique soil conditions.

An environmentally safe lubricant is then added between the annular gap and pipe to not only fill the space, but also protect the pipe. This lubricant helps to keep the friction between the soil and product pipe to a minimum.

Some of the benefits of using this method include:

  • minimal disruption to the community

  • increased worker safety

  • pipeline service life for owner

  • reduced liability and restoration costs

Auger or Road Boring


Auger Boring is a more traditional trenchless method of pipe installation. It is a simple, practical and cost efficient technology to install shorter lengths of pipes ranging in diameter from 24 and 70 inches. This method requires a smaller area to perform the work and requires more limited operator training, which results in a cost savings benefit for the owner.

Auger boring is the preferred method to install large diameter oil, gas and sewer pipelines as it creates extremely secure bores due to the lack of fluid traditionally used in other methods.

Auger boring involves a steel casing being simultaneously jacked into place as a rotating screw cuts advances through the soil. The resulting spoil is removed through the flighted auger out of the casing. This process is performed without the use of lubricant and the guidance mechanism actuator is located in the drive shaft.

One of the benefits of using the auger boring method is that it allows more accurate control over the grade of the bore, which is typically difficult to achieve in sewer pipeline installations.

Auger Boring is a method that is being reexamined in lieu of other trenchless methods as a simple, practical and cost efficient technology to install pipes ranging from 24 and 70 inches. This method requires a smaller area to perform the work and limited operator training, which both result in a cost savings benefit for the owner. Auger boring is the preferred method to install large oil, gas and sewer pipelines as it creates extremely secure bores due to the lack of fluid traditionally used in other methods. Auger boring involves a steel casing being simultaneously jacked into place as a rotating screw cuts ahead through the soil. The resulting spoil is then removed through the flighted auger out of the casing. This process is performed without the use of lubricant and the guidance mechanism actuator is located in the drive shaft. One of the benefits of using the auger boring method is that it allows more accurate control over the grade of the bore, which is typically difficult to achieve in sewer pipeline installations.

Sheet & Pipe Pile Driving



Sheet Pile Driving
is a process that involves driving long, interlocking steel sheet piles into the ground to form continuous barriers. Sheet piles have a variety of applications, but are typically used to erect cofferdams and retaining walls and are designed to transfer pressure from the high side of the wall to the soil in front of the wall. This erection is achieved by using either an impact or vibratory driving method depending on the strata and condition of the soil. These conditions are explored by performing a soil investigation to determine which of these methods will cause the least disturbance of the surrounding soil.


Sheet piles can be used in both temporary and permanent applications and are typically used in soft soils and tight spaces. Temporary piles are used to provide safe access during construction and can be removed afterwards, where as permanent piles are used to support structures built on top of them.

Some of the benefits of using sheet pile driving to form barriers include: reduction in waste disposal, elimination of unnecessary site cleaning by using of alternative work areas and enclosure of irregular shapes are possible with use of this technology.
