ORANGE DEMARCATION FABRICS

Orange demarcation fabrics, also known as orange delineation geotextiles, are cost-effective tools that serve as visual warning layers in many subsurface geotechnical applications. During excavations the bright orange demarcation fabrics signal workers to proceed with caution. Project specifications vary, so we offer several types of demarcation fabrics and netting. Our most commonly used products are shown below. Please call us at 609-971-8810  so we can help you select the right material for your project. We welcome the opportunity to be of service.

APPLICATIONS

Environmental Construction – Soil Caps

In environmental construction and Brownfield applications, orange demarcation geotextiles can serve multiple roles at the same time, especially in landfill caps where they function to protect the sensitive liner system below. In soil cap applications, orange demarcation geotextiles act as a filter, allowing water to pass through while limiting upward contaminant migration. This warning layer marks contaminated soils prior to backfilling with clean soil, saving both time and money.  It also helps avoid costly removal and transportation of contaminated soils offsite.

Utilities

Underground utility corridors can benefit from the warning orange demarcation geotextiles provide. Installing the demarcation fabric around new or existing utilities (natural gas, electric, water, sewer, or data lines) helps to avoid costly downtime from damage during future excavations.

Historical Sites

Orange demarcation fabrics are effective at preventing damage to archaeological sites.  Federal and state laws require these sites be protected from construction damage, so it is vital to ensure they remain undisturbed.  Demarcation fabrics indicate the presence of these artifacts and act as a protective barrier while site work continues.  In addition, the demarcation fabric can remain in place afterward to protect against future damage.
