Ram Jack Colorado underpins a settling Centennial store with 32 helical piers
Ram Jack Colorado stabilized the north end of a Centennial, Colorado liquor store that had dropped as much as 3.5 inches over soft, moist fill sitting on sandstone. Crews installed 32 Ram Jack helical piers with 2-7/8-inch shafts and 10-inch helices to about 24 to 31 feet, reached a 7,000 lb-ft torque target, lifted the structure, foam-filled the voids under the slab and replaced roughly 1,343 square feet of sidewalk. The phased job let the store stay open for the whole project.

Why it matters
Commercial property owners can see how phased helical underpinning fixes differential settlement without closing the business while the work is done.
