Shifting Foundation
Sections of the garage were pulling away from the others, which is indicative of a shifting foundation.
Excavation
The first step to repairing this home is to excavate the the area around the foundation to expose the footing.
Helical Piers
Once the area is excavated, helical pier sections are mechanically "screwed", or advanced, into the soil. The weight of the home is then transferred through the helical piers to deep, competent soils.
Steel Foundation Bracket
Once proper depths and capacities are achieved, heavy duty steel foundation brackets, like this one, are positioned below and against the foundation footing. Helical pier systems create a solid supporting base that transfers the weight of your home downwards to strong supporting soils.
Helical Tiebacks
Once the foundation was stabilized and lifted with the piers, holes were drilled into the foundation to install helical tiebacks.
Helical Tieback
Next, the helical tiebacks are screwed deep into the soil. The anchor's helical blades help to pull it deep into the soil and anchor it there.
Helical Tieback
After closing the hole in the retaining wall, a wall plate is installed and a nut is tightened over the protruding threaded rod to brace the wall. The wall is permanently secured in its position.
Foundation Repaired
After the repairs are completed, the hole is backfilled. The foundation is now secure and stable, and will not shift anymore!
