Structural Underpinning
Underpinning can remedy a wide range of support
problems that affect a building or slab. The
challenge as with most stabilization methods is to
get the piles within and around the settled portion
of an existing structure.
Bonsai overcomes limited
access restrictions while still delivering a compact
but powerful pile installation as follows:
1.
Excavate at each pier location
2.
Attach the lifting bracket to foundation or slab
3.
Load test each pier
4.
Connect the lifting rams
5.
Simultaneously lift the structure
6.
Check all elevations during and after the lifting
7.
Weld the lifting brackets to the installed pile
8.
Remove the hydraulic lift units
We can locate critical bearing points to help lift
and relevel those settled portions of the foundation
or slab. This will allow us to realign sticking
doors or windows.
