Welcome to A.T.T'S directional drilling page

This technique is ideal for the installation of small to medium diameter pipes and ducts on a straight or curved alignment. It is used extensively by the gas, water, telecoms and electricity industries.
 
The process is a quick and effective means of installing single or multi pipes and ducts from 25mm to 900mm diameter.
We pride ourselves in offering a service that leaves environmentally sensitive landscapes unscathed during the directional drilling process.
By using our large fleet of steerable direction drilling rigs, we can provide a precise and controlled bore in which the final product pipe(s) can then be pulled to completion.
 
Advantages of Horizontal Directional Drilling
 
Quick, efficient and therefore economic/cost effective

No disruption to the surface infrastructure or services

Unaffected by surface obstacles

Cost effective and time saving alternative to open cut methods when installing pipes amidst extensive underground infrastructure or at significant depths

Relatively small overall footprint for the Works

Pipework and cables can be installed in either a straight or curved alignment to help avoid underground complications and services.

HDD requires no deep excavations due to the equipment that is used.

Can be used for gravity gradient installations where the required grade and ground conditions allow

A reduced requirement for possessions, road closures, opening notices etc, if required.

A reduced requirement for restricted working hours

A reduced requirement for premium rate working
 
Distances: Pipe lengths up to 400 metres.
 
Installation rates: Up to 200 metres per day dependent on the required diameter and the ground conditions.
 
Accuracy: +/- 50mm Ground dependent.

Guided Auger Boring (GAB)
 
 
 
Guided Auger Boring is the ideal solution for trenchless installations where accuracy relating to line, level and gradient is critical. By utilising an Optical Guidance System, this quick and efficient trenchless technique can complete thrust boring activities with little or no risks of heave and settlement, with minimal disruption to the surface, surrounding areas and services.
Originally designed and predominately used for drainage, Guided Auger Boring is evermore becoming the methodology of choice for duct installations, particularly in sensitive areas or in adverse ground conditions.
This technique is the ideal No-Dig solution for gravity pipelines, drainage pipes and various ducting requirements.
 
Distances: Pipe lengths up to 100 metres.
 
Installation rates: Up to 10 metres per day dependent on the required diameter and the ground conditions.
 
Accuracy: +/- 1% ground dependent.
 
Vitrified Clay (VC) and Concrete installations: Diameters ranging from DN150 to DN900 are available and any combination of pipes or ducts can be inserted.
 
Steel sleeve installations: Diameters ranging from DN100 to DN1200 are available and any combination of pipes or ducts can be inserted.
