Rock Boring

(Sometimes referred to as DTH Drilling)

With our extensive experience Allen Watson has designed, built and operates a versatile range of rock boring methods. These include DTH rotary and pneumatic systems some steered and non-steered. Working in conjunction with our auger equipment the key to successful Rock and overburden boring is planning, engineering and selection of the correct drilling technique with particular attention to formation and rock strength.

What is Rock Boring?

Using specially designed and manufactured equipment including button bits or roller cones, Rock and overburden is crushed simultaneously allowing the cutting head to pass forming the bore.

Advantages include:

• Installations over distances up to 100 metres possible.
• Can operate from surface or shafts.
• Can install variety of pipe materials.
• Rock boring is unaffected by surface obstacles.
• By boring underground the working area is confined to points of entry and exit only.
• No disruption to surface, buildings, road, river, rail or traffic.
• Can be used to install pipes in changeable ground conditions.
• Rock boring is relatively quick and in many cases has lower overall costs.

Typical Applications

Steel or Polyethylene pipes and ducts from 100mmØ up to 900mmØ in distances from 5 metres up to 100 metres have been successfully installed under Railways, Roads, Rivers, Airports, Buildings, Contaminated landfill sites and Sites of Special Scientific Interest.

Crossings can be for Water, Oil, Gas, Electric, Sewage, Chemicals, Communication Ducts and Outfalls.
