Failing Retaining Wall Stabilization


Heavy rainfall and inadequate drainage caused failures of two Mechanically Stabilized Earth (MSE) walls that were constructed within a condominium complex located in central Georgia. The failed/failing walls ranged from 16 to 24 feet tall and were as close as 25 feet to the multi-story condominiums. Cracks were evident within the building structures and tension cracks had formed in front of the buildings.

GeoStabilization International® provided design/build/warranty services to permanently stabilize the failed and failing retaining walls using high capacity soil nails with lengths up to 45-ft in multiple rows throughout the existing wall. The soil nail ends were left protruding through the wall to provide anchorage points to attach oversized galvanized steel plates. In areas where the wall had completely failed, steel reinforced shotcrete was anchored to the soil nails ends and the blocks were restacked to match the existing wall height and geometry.
