About Directional Drilling and Services offered by Drillco
Drillco Ltd specialises in installing underground ducting to carry a range of infrastructure delivery systems ie gas, power, water, and sewer.
Horizontal and Directional Drilling (HDD)
Horizontal directional drilling is extremely protective towards the environment, causing only minimal ecological damage within the vicinity of the unit itself. Application of the directional drilling technique in urban areas is particularly effective in minimising:
- construction costs
- length of construction periods
- permission procedures
- soil movement
- disruption to traffic
- project delivery (on time and on budget)
The application of HDD units enables trenchless installations up to 500 m in length per drill shot. Crossings underneath rivers and streams are frequently performed. The directional method makes drilling underneath industry complexes possible. The spectrum of application includes all pipe construction measures and including gas, heating and potable water supply, the installation of pressure lines for sewers as well as cable protection pipes for television or telephone cables, traffic routing systems, emergency call boxes or low, medium, high voltage and optical fibre cables.
Open trench excavation consists of excavating down to and exposing the existing pipe so that it can be repaired or replaced. Open trenching may be required if the new installation is complex, or too many services are located therefore removing the ability to underbore. This process requires an open trench allowing for the new services to be installed. The trench is then backfilled to surface level with sand and metal and then subsequent resurfacing.
The aim when potholing is to expose the underground services. Depending on the likely depth of the infrastructure, potholing may be undertaken by mechanical excavator or by the use of hand tools (general shovel or similar) to expose any infrastructure.
Drillco utilises specialised Hydro Vac excavation technology to expose the critical or sensitive infrastructure. This method is safer than using either mechanical or hand tools and widely accepted by most discerning owners of underground infrastructure.
Hydro Excavation is the process of removing or moving soil with pressurized water. An air vacuum is then used to transfer the soil or debris to a tank. This allows for a non-destructive and more accurate way to excavate soil by cutting through the soil and breaking it up. The primary benefit is that it provides for increased safety and control. Its accuracy limits accidents and injuries and avoids damage to underground pipes, lines and cables.
Our projects often require reinstatement once completed. All reinstatement work is completed to the highest standards and always complies with local council specifications.
