Micro Tunnelling

Innovative Drilling can install up to 18 inch diameter pipes in any material from sand to hard rock.

Less than a foot underneath a high-pressure cast iron water main, this drill rig was drilling to install five eight inch casings. Quinn Street, Halifax, Nova Scotia.

Innovative Drilling designed a drill rig used to bore through boulder-strewn glacial till at the Burnside Industrial Park, Nova Scotia. The rig bored 25 meters underneath railway tracks for the instillation of natural gas lines. Before boring with this rig, a welder secured the next set of drill casings onto the drill head.

Case study – Mod-U-Form Limited needed to install a 65 foot long sewage tunnel in 2004. The tunnel was to go underneath the Beaverbank Road intersection in Sackville, Nova Scotia. A number of factors contributed to the difficulty of this job. First of all, the tunnel had to go underneath a four-road intersection and through solid rock. Secondly, the tunnel had to bypass a high-pressure water main and fibre optic cables. Innovative Drilling addressed these factors when micro tunnelling. The company did not disrupt traffic. They also came within eight inches of the high-pressure water main at the end of the tunnel as specified.

“I was amazed by the accuracy Innovative Drilling provided. Their contribution to the project by-passed the traffic control problems we would have experienced otherwise.”
