LITTLE MULBERRY CREEK – ALABAMA – CASE STUDY

THE Exposed Pipeline Remediation Experts

Submar Case Study – In our latest case study, discover how Submar protected a 24-inch natural gas pipeline that was exposed for 10 feet due to headcutting at Little Mulberry Creek in Chilton County, Alabama. The site was dewatered using sandbag dams and pumps. Both banks and the streambed were graded, and a geotextile material was placed on top of the grade. A Submar articulating concrete mat system was installed from high bank to high bank to armor the pipeline. All edges of the mat system were toed into anchor and flank trenches that were backfilled with existing material and rip rap. A subgrade rock grade control was installed downstream of the mat system to prevent headcutting. Geotextile and rock were installed on the banks for bank paving.
