Newbridge sits on the edge of the Curragh plain, an area defined by its glacial history. This means the ground beneath the town is not uniform. You find dense tills deposited by ice sheets right next to pockets of soft alluvium along the River Liffey. A standard trial pit often cannot reach the depths needed for a commercial foundation here. We run the CPT to map these drastic changes continuously. The 20-tonne rig pushes a cone through the soil, measuring tip resistance and sleeve friction in real time. For projects near the Whitewater Shopping Centre or the expanding industrial estates, this data is essential. It helps engineers avoid surprises when they hit a loose lens of sand at depth. We have seen standard borehole logs misrepresent the actual layering by up to 20 percent in this area. Combining a CPT profile with a targeted Sondaje SPT campaign confirms the soil parameters needed for a safe design.
We push the cone until refusal or until we have the data the client needs. No guesswork, just a continuous log of the ground.
