INSTALLING DUCTING WITH DIRECTIONAL DRILLING

Directional Drilling is the ideal solution for installing ducting as it minimalizes the need for trenches and the disruption to people and the environment.

A duct can be installed far faster than using traditional trenching methods, far cheaper and can often be done without having to close the area which is having the ducting installed.

Installing Utilities with Directional drilling

Directional drilling, also known as horizontal directional drilling (HDD), is a method used to install underground utilities such as pipes, conduits, ducts or cables.

Directional drilling involves creating a borehole at an angle (rather than straight down) to establish a pathway for utility installations.
Utilities installed using this method include water and gas pipes, fiber-optic cables, ducting and electrical wires.

The primary goal is to minimize surface disturbance, reduce environmental impact, and enhance safety.

How Directional drilling Works:
A small-diameter pilot hole is drilled along a specific path from one surface point to another.
The bore created during pilot hole drilling is then enlarged to a diameter suitable for installing the desired pipeline.
Finally, the pipeline is pulled into the enlarged hole, creating a continuous segment of pipe underground.

Advantages of Directional Drilling:
Reduced Environmental Disturbance: Unlike traditional cut-and-cover methods, directional drilling minimizes disruption to the environment and local communities.

By avoiding extensive excavation, the risk of accidents is significantly reduced.
Cost-Effectiveness: Although initial setup costs may be higher, long-term benefits include lower maintenance and repair expenses.

Suitable Soil Conditions:
Directional drilling works well in various soil types, including clay, silt, sand, and rock.
Problematic conditions include excessive rock strength, poor rock quality, and the presence of large gravel, cobbles, or boulders.

Directional Drilling Equipment:
The choice of equipment depends on factors such as the length of the crossing, pipe properties, and subsurface conditions.
Small HDD drill rigs are used for mini-sized drilling, while maxi-sized HDD rigs handle larger projects.
