Description

A segmented block wall detention pond structure was built in 2023 at a site located in Texas. The 17-ft tall wall experienced failure. The purpose of our study was to identify the causes of segmented block wall detention pond failure and develop recommendations on wall replacement. These objectives were met by (1) conducting site visits, (2) performing field exploration, (3) conducting laboratory testing, (4) reviewing existing data and reports by others, and (5) analyzing the data to develop engineering analysis. The potential causes of the block wall detention pond failure at the project site could be attributed to (a) inadequate design, (b) improper construction, and (c) improper materials.
