Concrete Slab Stabilization - Wilmington, MA

Problem:
The concrete slab for this warehouse was buckling down under the heavy vehicle loads from trucks entering the warehouse. This was most likely caused from poorly compacted fill soils underneath the settling concrete slab, allowing a void to develop underneath. Removal of the concrete was not a viable option in that this area was at the entranceway to the warehouse, and trucks needed access to the buildings every day. The work had to be completed within a very short timeframe.

Solutions:
Northeast Helical LLC mobilized a pressure injection pump and grout plant to repair the concrete slab. Multiple access holes were drilled in the slab through which the grout was pumped through. The underslab voids were fully filled, and the entranceway was back in use almost immediately
