We provide professional Horizontal Directional Drilling (HDD) services for the safe and efficient installation of underground utilities. Our experienced civils teams use HDD to install cable ducts, pipes, and conduits with minimal surface disruption, helping clients complete projects faster and with a smaller environmental footprint.
Horizontal Directional Drilling (HDD) is a trenchless method used to install underground utilities by drilling a guided bore beneath the surface, then pulling the required duct or cable through the created path. It is ideal for crossing roads, rivers, railways, or densely built-up areas where open-cut trenching would be impractical or disruptive.
In power and utility projects, HDD provides clear advantages. It reduces excavation, minimises reinstatement, shortens programme durations, and helps maintain public access. The technique is also environmentally responsible, protecting existing infrastructure, landscapes, and habitats while delivering accurate, high-quality installations.
At Electricity Asset Services, we combine detailed technical planning with experienced site delivery to ensure every HDD operation is completed safely, efficiently, and to specification. Our teams carry out thorough ground condition assessments, manage drill paths with precision, and maintain full compliance with environmental and safety standards. We work closely with design, electrical, and reinstatement teams to ensure seamless coordination across the wider project scope.
