Process and Applications- social (2).pngThe Deep Lift™ process is different from common slab lifting in that it requires polyurethane foam to be injected deep into the soil beneath the structure. Deep Lift™ is often appropriate for certain larger structures and more flexible pavements that may not be ideal candidates for conventional slab lifting. It can also be used in conjunction with conventional slab lifting. In this post, I'll provide a quick overview of the Deep Lift™ process and its many applications.

The Process:

  1. Complete a thorough site evaluation including – soil borings, DCP testing, and GPR as necessary
  2. Address any potential binding with saw cutting, clearing of joints, and removal of old grout
  3. Based upon soils data, calculate grid spacing and injection depths
  4. Drive injection tubes to the correct depths and locations
  5. Inject the appropriate AP Lift series polymer(s) in the predetermined sequence while monitoring for lift
  6. Follow the grout plan, adjusting the injection depths and locations as the structure raises into place

The Applications:

  • Bridge abutments
  • Highway approach slabs
  • Rigid and flexible pavements
  • Ports and airports
  • Settled buildings
  • Soil densification and encapsulation
  • Lift stations
  • Pipe and tunnel segments
  • Equipment pads
