When a swampy and saturated build site causes serious problems with compaction, a commercial project is threatened. See how our team overcame challenging soil to deliver an economical foundation.
Postech Moncton was approached by a client who was looking to build a Jiffy Lube location on an existing site. However, the job site was located in an area that was originally a swamp. Ground conditions were wet, mucky, and soft.
Building plans called for poured concrete beams to support the structure, but there were engineering concerns about the bearing capacity of the soil.
The engineer requested that fill be added to ensure the ground was suitable for construction. In response, the client obliged and had large amounts of fill brought in. Unfortunately, the fill did not improve conditions enough to gain engineer-approval.
With money already invested in the site and facing the prospect of having to abandon it, the client was in serious need of a foundation solution that would overcome muddy conditions and allow their project to continue.
Once our team had a good look at the site and understood the difficult conditions, we knew there was only one solution: go deeper.
We determined that by installing helical screw piles to 20' deep or more, the swampy layer could be avoided and the foundation anchored into strong soil. Coordinating with our client's engineers, Postech Moncton designed the piles and top-plates so rebar could be easily tied-in to transition to concrete beams. We also handled the loading calculations.
During the design process, we established required torque figures for the screw piles. One of the huge benefits of a screw pile foundation is we can use torque to ensure the safety, quality, and accuracy of installation by confirming we're anchoring the pile in firm soil.
Our installers used a digital torque reader to monitor and record installation depth and torque in real-time, giving the client and their engineers complete confidence and traceability.
It only took one single week to install the helical screw piles. Using 5' extensions allowed us to quickly install each pile to the appropriate depth and torque.
Rebar was then tied into the pile caps, concrete poured, and the construction on Jiffy Lube would be successfully completed.
