Case Study Details

The University of Florida upgraded the drainage infrastructure behind a large concrete gravity retaining wall to improve stormwater flow and reduce hydrostatic pressure. Located on campus as part of a landscape-focused infrastructure project, the gravity wall was retrofitted with 38 JET Filter maintainable weep hole drains to ensure long-term structural performance and protect surrounding landscaping elements.

Products Used

• 38 units of JET Filter – JF3SS: 3″ Diameter Open End Maintainable Weep Hole Filter, featuring ASTM 316/316L Stainless Steel Housing and Mirafi® Filter-Weave FW 300 Geotextile Filter Media.

Solutions

In collaboration with Crisdel Group, Inc. the project team installed 3″ diameter maintainable weep holes. These systems were installed at regular intervals through the concrete wall to relieve trapped water, prevent sediment loss, and protect the wall’s structural and aesthetic integrity within a landscaped environment. Gravity walls built for landscape applications often experience: constant irrigation, rain runoff pooling, soil erosion and settlement, root intrusion if drainage is poor.
