Significant Foundation Settlement Case Studies
Hilton Head Island boasts stunning scenery, gorgeous homes, and wonderful
weather for much of the year. Unfortunately, not as much can be said for
the soil on which many of the homes rest, as it varies in quality despite
the overwhelming beauty of the structures it lies below. A stunning home
with a pool in the heart of Hilton Head Island, had developed major structural
issues due to this problematic soil, and Ram Jack South Carolina was brought
in to take care of it.
Situation: The residence had significant foundation settlement throughout the entire
home. The main rear wall had settled as much as 4 in. in some areas. This
drastic settlement put the home in serious danger of severe damage. The
home desperately needed a permanent repair to prevent further damage.
Proposed Solution: Working with Applied Building Sciences Inc., an architectural engineering
company located in Charleston, SC, Ram Jack South Carolina proposed using
helical piles to permanently lift and stabilize the home to its original
position. The structure was strategically mapped out based on geography
and the severity of settlement, and helical piles were assigned positions
Outcome: After encountering some obstacles and coordinating with Applied Building
Sciences, the original plan was adjusted, as it was discovered during
demolition that the underlying foundation did not match what was expected.
With a foundation deeper than expected, and the nearby pool and deck,
continuing with the original plan would have been incredibly expensive,
so that plan was scrapped for a more prudent one. All in all, 31 helical
piles were used to underpin the existing interior, 42 helical piles were
installed to support the existing perimeter footing, and five helical
piles were used to bolster portions of the exterior walls. The structure
was stabilized; no lift was attempted, as it was not feasible or practical.
Working underneath the entire structure in damp, close conditions, Ram
Jack South Carolina completed the repair in just four days.
