Ram Jack Foundation REpair

A Permanent Solution for Alaskan Earthquake Damage

Anchorage, Alaska

PROBLEM

When a magnitude 7.1 earthquake wrecked havoc on the foundations in their community in November 2018, Anchorage homeowners the McCann's saw immediate foundation damage. Like many in their community, the earthquake had caused the soil beneath their home to liquefy and their foundations to settle several inches almost instantly. After seeing the recent seismic testing which was performed at the University of California San Diego using Ram Jack helical piles, the McCann family knew exactly who to call, Ram Jack West. Ram Jack’s steel piles extend through liquefiable soils with the strength to support structural loads but are slender enough to act as a damping system. By the piles acting as a damping system, the full force of the earthquake is not transferred to the structure. 


PROPOSED SOLUTION

After a thorough examination of the project, Ram Jack West proposed a solution of 63 piles as well as poly foam injection. 50 of the piles were needed in the large crawlspace area, 11 on the exterior of the garage’s foundation, and 2 piles were to support the entry’s overhang support columns. Polyfoam was to be injected beneath the footings, as well as leveling and void-filling the floor slab of the 3 car garage. 


OUTCOME

The project went as planned, recovering 3 inches of settlement and reaching maximum practical recovery. The McCann’s were left with peace of mind and said that “Ram Jack West’s crew did a phenomenal job start to finish, keeping up updated as each phase of the project took place. Very happy they were able to get us in before the ground froze.” They know they don’t have to worry about another earthquake wrecking their home.
