What is Horizontal Directional Drilling (HDD)?
HDD is a trenchless construction method used to install underground utilities with minimal surface disruption.

 

What types of projects use HDD?
HDD is commonly used for water, sewer, gas, electric, fiber, and conduit installations under roads, rivers, buildings, and other obstacles.

 

Why choose HDD instead of open trenching?
HDD reduces surface damage, lowers restoration costs, minimizes traffic disruption, and is faster in many situations.

​

What factors affect the cost of HDD?
Soil conditions, bore length, pipe size, depth, access, and required restoration all impact pricing.

​

Is HDD environmentally friendly?
Yes. HDD minimizes soil disturbance, protects landscapes, and reduces erosion and runoff.

​

What ground conditions can HDD handle?

HDD works in many soil types, including clay, sand, and rock. A site evaluation determines feasibility.

 

Is HDD more expensive than trenching?

While upfront drilling costs may be higher, HDD often saves money overall by reducing restoration, traffic control, and downtime.

 

How accurate is HDD?

Modern locating systems allow for precise steering and depth control, allowing bores to be spot on accurate.

 

What is hydro excavation?
Hydro excavation is a non-destructive digging method that uses pressurized water and a vacuum system to safely expose underground utilities.

 

How does hydro excavation work?
Water loosens the soil while a vacuum removes the slurry and transfers it to a debris tank, leaving a clean and precise excavation.

 

What is hydro excavation used for?
It’s commonly used for utility locating (potholing/daylighting), trenching, pole holes, sign foundations, pipeline exposure, and confined or sensitive dig areas.

 

Is hydro excavation safer than traditional digging?
Yes. It significantly reduces the risk of damaging underground utilities and improves worker safety.

 

Can hydro excavation damage existing utilities?
When done properly, it’s one of the safest methods for exposing utilities without damage.

 

Is hydro excavation accurate?
Very. It allows for precise excavation, even around crowded or shallow utility corridors.

 

Can hydro excavation be done in winter?
Yes. Heated water systems allow excavation in frozen soil.

 

Does hydro excavation work in tight or congested areas?
Yes. The equipment can excavate from a distance, minimizing surface disruption.

 

Is hydro excavation more expensive than mechanical digging?

The hourly rate may be higher, but it often saves money by preventing utility damage, reducing restoration costs, and improving efficiency.

 

What factors affect hydro excavation costs?
Depth, soil conditions, access, water usage, debris disposal, and project duration.

 

What is trenching?
Trenching is an excavation method used to install or repair underground utilities by digging a narrow, linear trench.

 

What is trenching used for?
Trenching is commonly used for water lines, sewer lines, storm drainage, gas lines, electrical conduit, fiber, and other underground utilities.

 

When is trenching the best option?
Trenching is ideal when utilities are shallow, access is open, or when directional drilling or trenchless methods are not feasible.

 

What soil types can be trenched?
Trenching can be performed in clay, sand, loam, gravel, and some rocky conditions.

 

How deep can trenching go?
Depth depends on the utility being installed and soil conditions, but trenching can reach several feet deep safely.

 

Can trenching be done in tight areas?
Yes. Compact equipment allows trenching in residential yards, alleys, and confined spaces.

 

Is trenching cheaper than trenchless methods?

Trenching often has a lower upfront cost but may require more surface restoration compared to trenchless options.
