Project Overview
During a construction project along the Delaware River, contractors needed to manage contaminated soils disturbed within the work area. Uncontrolled sediment migration risked spreading contaminants into the broader river system, threatening both environmental compliance and project timelines.
The challenge was to provide a containment solution that could withstand river depths up to 50 feet, maintain stability, and allow water flow while trapping and controlling suspended particles.
Objective
Confine contaminated soils and suspended particles within the designated work zone, preventing migration into the wider Delaware River ecosystem.
GEI Works Solution
GEI Works engineered and supplied a Type 3 Heavy-Duty Permeable Turbidity Curtain equipped with a Y-seal ballast bottom. This design ensured the curtain followed the riverbed contour, creating a secure perimeter seal while still allowing controlled water movement.
Key Features:
-
Type 3 HD Design – built for strong currents, deep water, and heavy-duty use
-
Y-Seal Ballast Chain – provided full contact with the riverbed, preventing particle escape
-
50-foot Depth Capability – successfully deployed to meet extreme depth requirements
Project Highlights
-
Containment of Contaminated Soils
The curtain confined disturbed sediment within the designated zone, maintaining environmental compliance. -
Deep-Water Deployment
With depths reaching up to 50 feet, the curtain performed reliably, maintaining a sealed perimeter. -
Secure Worksite Conditions
Allowed construction activities to proceed while protecting the surrounding waterway.
Outcome
The Type 3 HD Permeable Turbidity Curtain with Y-seal ballast enabled contractors to complete their work while safeguarding the Delaware River from contaminated particle migration.
This project highlighted GEI Works’ ability to design and manufacture custom deep-water turbidity solutions that meet both environmental and operational demands in challenging construction environments.
