ABSTRACT
This chapter describes the failure, investigation, and remediation of two sections of a geogrid reinforced segmental concrete block retaining wall. This wall was completed in August 1997 and was followed by heavy precipitation in the following fall, winter, and spring. The first failure occurred without any warning about 5 months after construction. The second failure occurred at a different location in the wall about 5 months after the first failure was repaired. The second failure was progressive and exhibited large deformations for several weeks before the collapse occurred.
