Underpinning is the process of strengthening and stabilizing the foundation of an existing building or other structure.

  1. Sections between 32” - 48” (as per drawings) are marked around the interior perimeter of your basement, they are numbered 1,2,3 1,2,3…..
  2. Excavation begins with digging out all number 1’s in a pocket, out 24” from your wall down to the requested height and then under your existing footing til we reach the outer side of footing
  3. Once all number 1’s are dug and cleaned they are inspected by the city
  4. Then a form is placed in front of the open hole leaving out 4” so that when the concrete is poured it encapsulates the existing footing.
  5. The concrete is vibrated so that all the space is filled with concrete creating an overpour of your footing.
  6. Once the number 1’s are poured the same process is taken with the number 2’s and 3’s
  7. When all sections of underpin are poured the earth in the center is then excavated to the desired height
  8. Then a plumber needs to be brought in to replace all old piping.
  9. Once plumbing is complete floor is leveled, delta membrane is installed on all interior walls and a continuous clothed weeping tile system directed to a sump barrel.
  10. At this point you also have an option to choose if you want to put down 2' insulation or have in floor heating installed
  11. 4” of gravel is then laid on top covered by 6mil poly and with wire mesh.
  12. We then pour a 4” concrete slab leveled with a smooth finish
  13. Apporx. start to finish 6-8 weeks
