THE Exposed Pipeline Remediation Experts
Submar Case Study – In our latest case study, discover how Submar protected a 10 inch natural gas pipeline that was exposed for 16 feet and suspended due to headcutting in a tributary to Dilworth Run in Beaver County, Pennsylvania. The site was dewatered using sandbag dams and pumps. The 6-inch abandoned pipeline was removed. 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.
