- ShoreFlex costs less to install than rip rap
- Once installed, ShoreFlex requires no maintenance
Background
Woolridge Road and Otterdale Road are a heavily trafficked, connected two-lane road in Chesterfield, Virginia. The Department of Transportation undertook a roadway rehabilitation project, which included installing a sediment basin just off the shoulder.
Project Scope
Once the project was completed and a chain-link fence was installed around the basin, the inspector noticed a scouring issue at the base of the pipe outfall leading to the basin. Curtis Contracting Inc., was tasked with providing a permanent solution to protect the basin. The inspector suggested the contractor use rip rap to stabilize the outfall. However, it was logistically impossible to use rip rap without closing the road for delivery and taking down the fence to complete installation.
Method
Quickly deliver a sufficient amount of ShoreFlex erosion control mats on a 12′ flatbed truck that could fit on the shoulder of the road, allowing traffic to pass. The product was conveyed over the chain-link fence using its lifting straps, quickly unrolled, and anchored down for permanent stabilization of the pipe outfall.
The Solution
The Virginia Department of Transportation partnered with ACF Environmental—now Ferguson Waterworks—because of great customer relations and an established reputation for providing innovative solutions. We were able to provide prompt delivery and on-site support during installation.
