IWT Cargo-Guard is proud to introduce Geotex® OR DND, the first printed NONWOVEN demarcation geotextile. Geotex OR DND is a highly visible orange nonwoven geotextile fabric printed with the text “DANGER DO NOT DIG / PELIGRO NO EXCAVAR”

Turbidity Barriers/Silt Curtains

Turbidity barriers, also known as floating turbidity curtains, silt curtains, silt barriers or silt screens, prevent the migration of silt and sediment from a work site into nearby waterways.   Applications include dredging, pile driving, remediation and shoreline restoration.

IWT’s Cargo-Guard division contract manufacturers quality railcar liners as well as custom dump truck, dump trailer and roll-off container liners for safe, reliable transport of contaminated materials. We can also design custom railcar liners and covers for specific projects.

Geosynthetics

Geosynthetics can be used alone or together to significantly extend the life of everyday structures providing one or more of the following functions: separation, reinforcement, filtration, drainage, containment, surface erosion control, and protection.

PROJECT SPOTLIGHT

Project: Northern States Power Superfund Site / Ashland, Wisconsin
Contractors: J.F. Brennan Company, Inc & Envirocon, Inc

When JF Brennan and Envirocon needed to design a custom turbidity curtain layout for the Ashland/Northern States Power Superfund project in Ashland Wisconsin, IWT Cargo-Guard and Spilldam Environmental were called upon to come up with a curtain system that would work  and satisfy the oversight engineers and the regulatory authorities. The material to be dredged NAPL (non-aqueous phase liquids) can be particularly difficult to work with as it coats and clogs almost everything it comes in contact with. By working closely with the engineering company and the onsite contractors,JF Brennan and Envirocon, a multi-tiered approach was designed to provide a fail safe containment system. The system consisted of bedload baffles, carbon curtain, and  turbidity barriers / silt curtains designed specifically for this project site.
