Jack-n-Bore Method

Jack-n-Bore Method also knowns as “Auger Boring” is the process of forming a horizontal bore by jacking the steel casing through the earth from one side of the site to the other side.

The starting point and ending point could be from vertical pits, toes of embankments, or combination of either. Spoil is removed from inside the encasement by means of a rotating auger. These rotating augers carry the spoil back through the casing pipe to the main auger machine for removal. The jack-n-bore machine, also knowns as an “Auger Boring Machine” (ABM) bores through soil and/or rock with a cutting head attached to the ‘lead’ auger to install the proposed pipe.

While this is an established and cost-effective method, one of the limitations with jack-n-bore has been accuracy constraints. However, new technology has made a major impact on jack-n-boring, which provides more precise bores to expand its abilities.
