Alert® - Contamination Indicator Geotextile

Developing brownfield sites often involves safely containing underground hazards rather than removing them. Our Alert® geotextile provides a crucial warning layer, protecting future construction workers from accidental excavation into contaminated ground and ensuring long-term site safety.

What is the Alert® Contamination Indicator?

Geosynthetics Ltd developed Alert® as a clear and robust solution for marking buried hazards. This high-visibility orange geotextile serves as an unmistakable visual warning barrier when exposed during any future excavation work. Manufactured from high-tensile strength woven polypropylene tapes, Alert® is exceptionally durable and built to last underground for decades.

Beyond its primary warning function, it also acts as an effective separation layer between contaminated and clean fill materials. Alert® provides a simple, long-lasting, and effective solution for managing the risks associated with developing contaminated land.
