| Concrete
Slab Piering with Helical Piers
|
|
| 1) Signs of
settlement are detected. |
 |
| 2) Utilizing
a core drill, our pier technicians core
through the concrete slab at strategically
planned pier placement locations.
|
 |
| 3) Once the
holes are cored the pier technicians examine
the void beneath the slab to ensure that
they have enough room to mount a Helical
Channel Slab unit to the top of the soon to
be installed Helical Pier Piling. If there
is not enough room they manually remove just
enough soil to install the pier head
assembly |
 |
| 4) Utilizing
a hydraulically driven gear motor the
helical pilings are driven (torqued) through
the soils beneath the concrete slab until
they have reached a layer of soil with
sufficient bearing capacity to stabilize the
concrete slab. |
 |
| 5) After the
pilings are driven the piling is cut off
just below the slab level. A Helical Channel
Slab Assembly is then mounted atop the
piling. (The Channel Slab is the steel
rectangular object attached to the ratchet
and residing just beneath the concrete slab)
From here our pier technicians are able to
use a ratchet to easily lift the settled
concrete slab. |
 |
| 6) After the
slab is lifted the cored holes are then
sealed off by placing and finishing concrete
evenly to the top of the slab. |
