Directional drilling

Directional Drilling
Trenchless technology involves the rehabilitation of existing underground utilities such as water, sewer, storm, gas and electrical conduits as well as the installation of new underground infrastructures.
The technology uses methods that minimise the construction impacts normally associated with the conventional open cut construction methods.

Instalcom provide a design service for all new drill locations, the design will assess the ground conditions and confirm the feasibility of the proposed drill whilst taking into account the environmental impact.
Instalcom has completed many projects employing trenchless technology. Always at the forefront of technological development, we have been commended for innovation in our project work.

There is a reduced impact on the environment resulting from less surface disruption – crucial in sensitive sites such as areas of national or scientific importance.

Site safety is more effective managed as the actual worksite is vastly reduced.

Construction impacts are minimised compared to the conventional open cut construction methods.

There is a reduction in the imported material for backfill and pipe bedding.

The minimal trench construction improves the long term sustainability of the surrounding area or pavement.

The methodology minimises noise impact and construction traffic, which are deemed to be causes for common complaint.

Costs can be substantially reduced where existing services are present or where deep excavations are required
