Looking for reliable conduit installation for your electrical or communication systems? Trenchless Drilling offers expert underground utility solutions that meet the highest standards of safety and code compliance. Whether it’s PVC, HDPE, or metal conduit, we install with precision.
We specialize in trenchless underground conduit runs, ideal for residential, commercial, and industrial sites. Whether it’s for 200-amp service, fiber optics or parking lot lighting, we meet all NEC depth and spacing requirements.
Depending on the project requirements, soil conditions, and utility type, different conduit materials and methods are used to ensure long-lasting and reliable results.
Horizontal Directional Drilling (HDD) has become the industry standard for installing conduit systems in both urban and rural projects for various applications such as water, power, irrigation and several others.
Horizontal Directional Drilling (HDD) has become the industry standard for installing conduit systems in both urban and rural projects. For contractors and subcontractors, HDD provides an efficient, non-invasive way to complete underground utility installations while meeting strict project requirements.
1. Electrical Conduit
HDPE and PVC conduits are commonly pulled back through HDD bores to house medium- and low-voltage electrical lines. For high-voltage or high-capacity runs, multiple parallel conduits can be installed in a single bore to streamline construction and future access.
2. Telecommunications & Fiber Optics
Fiber networks and telecom providers rely on HDD for precise placement of single or multi-duct conduit systems. Innerduct is often added for organization, capacity expansion, and ease of pulling additional cables later.
3. Gas & Energy Conduit
Steel or HDPE conduits are used to encase natural gas service lines, ensuring strength, flexibility, and long-term safety. HDD allows contractors to complete gas line installations beneath roads, railways, or waterways without open-cut disruption.
4. Water & Sewer Systems
Municipal and private projects use HDD to install pressure-rated water lines or force mains. Specialized conduits and pipe materials (HDPE, fusible PVC, or restrained joint ductile iron) are selected depending on pressure ratings and soil conditions.
5. Multi-Duct Installations
In projects requiring power, data, and communications in a single right-of-way, HDD enables multi-duct conduit systems to be placed simultaneously. This minimizes excavation, reduces labor, and future-proofs the infrastructure corridor.
6. Protective Casings
Steel casing conduit is often installed where additional mechanical protection is required, such as highway or rail crossings. Subcontractors frequently complete these casings to support utility companies and municipalities.
For contractors and subcontractors, HDD conduit installation ensures faster project timelines, less surface disruption, and long-term durability, making it the most cost-effective and reliable method for modern utility construction.
At the core of horizontal directional drilling (HDD) is the safe and efficient installation of conduit underground without the need for disruptive open trenching. Depending on the project requirements, soil conditions, and utility type, different conduit materials and methods are used to ensure long-lasting and reliable results:
1. HDPE (High-Density Polyethylene) Conduit
HDPE is the most common choice in HDD projects due to its flexibility, durability, and resistance to corrosion and chemicals. Its seamless fusion welding creates a leak-free system, making it ideal for water, gas, electrical, and telecom installations.
2. PVC Conduit
PVC is lightweight, cost-effective, and easy to handle. While it’s more rigid than HDPE, it can be pulled through drilled bores for applications like telecommunications and power. Special jointing techniques are used to maintain integrity during installation.
3. Steel Conduit
For heavy-duty applications or areas requiring extra protection, steel conduit offers unmatched strength and resistance to external pressures. It is commonly used for casings, oil and gas pipelines, or situations where added durability is essential.
4. Multi-Duct & Innerduct Systems
In complex utility corridors, multi-duct or innerduct conduit systems allow multiple services (like fiber optic, data, and power) to be run in a single bore. This maximizes space, reduces future excavation needs, and provides easy access for upgrades.
5. Specialty Conduits
In certain cases, specialty conduits such as fiberglass or composite pipes are installed when specific environmental or engineering requirements are present. These options provide custom solutions for unique project challenges.
By tailoring the conduit type to each project, HDD ensures safe, cost-effective, and long-lasting underground utility installations with minimal disruption to the surface.
Horizontal Directional Drilling (HDD) is a modern trenchless method used to install underground utilities without digging large trenches. By drilling beneath the surface, HDD allows for safe, efficient, and non-disruptive placement of critical infrastructure. A wide range of utilities can be installed, including:
1. Water Lines
HDD is ideal for installing water mains and service lines under roads, rivers, or developed areas. The method prevents open excavation, reducing contamination risks and keeping communities supplied with clean water.
2. Sewer and Drainage Systems
Gravity sewers, pressure sewers, and storm drains can be installed using HDD. The process minimizes disruption in urban areas and ensures durable pipe placement for long-term flow and drainage needs.
3. Gas Pipelines
Gas lines require strong, sealed conduits. HDD safely installs polyethylene or steel gas pipelines underground, protecting them from damage and reducing the risk of leaks while maintaining service reliability.
4. Electrical Conduit
HDD provides an efficient solution for underground electrical distribution and transmission lines. By housing cables in HDPE or PVC conduit, HDD protects wiring from weather, traffic, and external damage.
5. Telecommunications & Fiber Optics
Fiber optic and telecom cables are among the most common utilities installed with HDD. The process allows high-capacity data lines to be placed underground without disrupting neighborhoods, businesses, or traffic.
6. Oil & Industrial Pipelines
For industrial applications, HDD is used to install oil, chemical, and slurry pipelines. The method ensures safe crossings under environmentally sensitive areas such as wetlands, rivers, and highways.
7. Reclaimed Water & Irrigation
HDD is often used for installing purple pipe (reclaimed water) and irrigation systems, especially in municipalities and agriculture, where minimal surface impact is essential.
The sewer connection point was over 2000 ft away from the development site and we successfully installed the force main via directional bore without having to cut open the road at any point
Replaced a 4" gravity fed sewer line replacement underneath the slab of an old office building to replace the deteriorating cast iron line.

For residential power lines, depth typically ranges from 18 to 24 inches, depending on local code.
Yes. PVC is common for underground and outdoor applications. We also offer EMT and steel options depending on project needs.
We use industry-approved fittings and cement when needed, ensuring a watertight and code-compliant seal.
Typically, a 2-inch conduit is used, but we always verify with your specific wire size and local code.
We use special masonry bits and wall seals to maintain both structure and insulation.
