Upgrading Deep Creek Culvert Drainage System | DelDOT Project
Middletown, DE
Industry: Transportation Infrastructure
Material: Concrete
Product: JF4SS
State: DE

Case Study Details
The Deep Creek Culvert in Middletown, Delaware, is a DelDOT drainage project that presented a significant challenge for the Delaware Department of Transportation (DelDOT). This aging infrastructure suffered from severe bridge culvert drainage issues, leading to damage, erosion, and degradation. Without proper drainage, hydrostatic pressure buildup behind the culvert walls could compromise the structure’s stability, necessitating immediate intervention.
Products Used
- 16 units of JET Filter – JF4SS: 4″ Diameter Open End Maintainable Weep Hole Filter with ASTM 316/316L Stainless Steel Housing and Mirafi® Filter-Weave FW 300 Geotextile Filter Media.
Solutions
To address these risks, DelDOT pursued an innovative and maintainable drainage solution to restore the culvert erosion control, performance, and longevity effectively. Mumford and Miller Concrete Inc. led the installation process, emphasizing strict compliance with industry best practices and ensuring a durable, long-term drainage improvement for DelDOT.
