Also referred to as Thrust Boring or simply Auger-boring, this technique offers a high degree of accuracy for line and grade, and is primarily used for the construction of gravity sewers.
Terra Solutions Limited operate a diverse range of Guided Auger Boring techniques that install pipe diameters ranging from 150mm to 1200mm. The units can operate from shafts/pits as small as 2.1m diameter, and can even be launched from existing manholes.
Usually clay or concrete jacking pipes are installed, however other pipe materials such as steel casings, PE and Hobas GRP are possible is certain circumstances.
Augerboring offers a highly accurate, cost effective technique with minimal ground settlement and is ideal for rail, water, road, runway and other crossings.
Terra Solutions are leading augerboring contractors and can offer both conventional and guided auger boring in diameters ranging from 150mm to 1200mm using equipment which can install pipes in a wide range of ground conditions including sands, silts, clays and even rock
Terra Solutions Ltd. was the first Company in Europe to employ the new Eliminator style of augerboring. The Eliminator requires no pilot bore and is suitable for tougher ground conditions including weak rock and non-displaceable solid (up to 100 N-value). The head has 3 independent steering control devices to maintain line/level and is suitable for graded pipelines such as sewers.
The Eliminator was originally used in 2013 at Gatwick Airport to successfully install 200m of gravity sewer in adverse ground conditions. Another reason why Terra Solutions leads the way in trenchless technology.
