Horizontal Directional Drilling

Trenchless Technology

Excavations are often expensive and highly disruptive. However, advances in technology mean that pipes and ducting can be installed and repaired without digging up the ground. Trenchless technology can be used for a range of purposes including horizontal directional drilling, impact moling, slip lining and pipe bursting. Trenchless technology is suitable for all sites including roads, airports and environmentally sensitive projects.

Trenchless technology is a way to reduce social costs and the environmental impact. It also offers economic alternatives to traditional open-cut methods of repair, renewal, or installation.

Trenchless technology eliminates the mess and waste that comes with digging and excavation.

Horizontal Directional Drilling (HDD)

Horizontal Directional Drilling is an environmentally friendly guided trenchless method where a pilot borehole is drilled along a pre-determined bore path.

Horizontal directional drilling is ideal for underground pipeline installations under roads, existing structures and environmentally sensitive areas. This type of drilling equipment can operate through a variety of different ground types and is launched from the surface with no need for deep excavations.

Moling

Moling is a fast and low-cost method for the installation of cables, ducts and pipes through a variety of different ground types. This method is usually used for smaller utility services such as water & gas pipes and electrical cables under roads, railways, driveways and existing structures.

Moling is an unguided soil displacement technique in which a percussive mole is launched from a small excavation to form a bore through the ground. This method is ideal for working in soft clays and silts.

Pipe Bursting

Trenchless pipe bursting is the fastest and most environmentally friendly method for replacing various pipe types including concrete, clay, and steel.

By using the existing pipeline as the guide, pipe bursting cuts through the existing pipe whilst pulling a new polyethene pipe into place behind it at the same time.

Sliplining

Sliplining is a trenchless method of inserting new pipes into damaged older pipes. This method provides a very convenient and cost-effective solution to the renovation of old pipes. Sliplining is suitable for water & gas repairs and renovations as well as sewer applications. Due to the ease of jointing and speed of installation, Polyethene pipes are now the most commonly used pipe replacement choice.
