Directional Boring

Directional boring also known as horizontal directional drilling (HDD) is a trenchless method for installing conduit, pipe, and cables using a drilling rig. By using a series of drill rods, the drill head is guided along a pre-determined bore path using electronic locating equipment. This locating equipment provides information such as the depth, location, pitch, and direction of the head. The bore path can be adjusted any direction to ensure line and grade accuracy. After completing the pilot bore, the bore path is enlarged by a reaming process. The pipe or conduit is then pulled back through the bore path once the reaming process has been completed.

Some common benefits of directional boring over trenching include less surface disruption, safer for the environment, directional capabilities, deeper installation possible, faster completion times and lower costs.

A lot depends on the ground conditions, but we’ve bored over 1500 ft. in one bore. Our crews typically will bore 750+ ft. per day in good soil conditions.

The maximum depth of the bore is dependent upon ground conditions. We commonly bore between the depths of 2 - 10 ft. Our equipment has the capability of drilling up to 50 ft. deep.

Most of the bores that we complete are for pipe ranging in size from 2” to 12” diameter.

Ideally, we like to bore in a straight line but realistically that rarely happens. If the ground conditions are good, our bore rigs have the ability to make turns. Although not common, we’ve bored up to a 180-degree arc in the past.

Yes, we bore under buildings as well as roads, ponds, streams, railroads, and other obstacles. When boring under buildings, we can install utilities into the floor of a basement or we can bore completely under the structure to get to the other side.

We have sophisticated electronics that give us all of the information that we need to know such as depth, location, pitch, and direction of the head. Inside the drill head is a transmitter that sends this data to a locating receiver above the ground.

Directional boring has very minimal impact on the environment. There is much less surface disruption and soil movement with horizontal boring as compared to open cut trenching.

We can bore in most weather conditions. Freezing temperatures and frost in the ground make it difficult to bore effectively. Snow also can create challenges as we’re unable to see locate paint markings on the ground. The majority of our boring happens between the months of March and December.


Yes, we can install a loop field on virtually any lot. We have successfully installed loop fields under lawns, driveways, parking lots, and even under buildings.

Yes, the heating and air conditioning contractor will install all of the necessary ductwork needed for comfortable and quiet operation. No more ugly and noisy wall or window units to deal with.

We use high-density polyethylene (HDPE) pipe, this is the same material used to transport natural gas across the country. The plastic carries a 50-year warranty. The pipe does not rust, rot, or corrode, and is inert to chemicals normally found in soils. The actual life expectancy of these systems is over 200 years. All joints are heat fused which results in the joints being stronger than the actual pipe itself.

Owners typically realize an energy savings of 30-70% over conventional gas, oil, or air source heat pumps.

There are many benefits to geothermal. There is no on-site combustion, eliminating the risk associated with carbon monoxide poisoning or gas leaks. Geothermal also offers lower maintenance costs and longer life expectancy than conventional equipment.

Geothermal systems have been around for a long time, but the popularity has really grown over the last 20-30 years. This is due to improvements in the efficiency and reliability of the equipment. Geothermal usage is growing rapidly due to rising energy costs and environmental impacts of fossil fuels.

Actually geothermal systems are typically sized to provide 95%+ of your heating needs. Typically the other 3-5% is made up for using either electric resistance or gas back-up. Systems could be designed and installed to provide 100% of your heating and cooling needs, but due to the operational costs of running larger equipment and the upfront cost of larger equipment it would take longer to recoup your investment.

The cost of installing space conditioning equipment varies depending on how you measure cost. If you only look at upfront installation costs, then yes geothermal typically costs more.

In an investment decision such as this, you have to factor in all associated costs of the investment. Geothermal has the lowest operating and life cycle costs of any space conditioning equipment. There is also the added value of comfort with the even temperatures supplied with geothermal. A geothermal system will also be much quieter compared with traditional equipment. You will not have to listen to a noisy outside air conditioner rattle next to your window or deal with the air conditioner rejecting heat next to you while you are trying to enjoy your patio or deck.

The biggest added value is the great energy savings in comparison operating traditional equipment. There is also the increase value to your home because of the energy saving equipment. Additionally, with the 30% Federal tax credit you will be able to recoup your investment even faster.

Yes, even when it is really cold outside. We have installed loops at 5 Degrees with -20 degree wind chill.

We want to install the most cost-effective loops for your property.  We can meet with you to discuss lots size constraints and future plans to help determine the best loop option and location for your property.
