FODS Trackout Control Mats
New Zealand’s smarter, cleaner alternative to rock pads.
FODS (Foreign Object Debris System) is a heavy-duty, engineered polymer mat system that removes debris, mud, and sediment from vehicle tyres as they exit your site. The mat’s unique pyramid pattern flexes under vehicle weight, dislodging material without damaging tyres or relying on loose aggregate.
Ideal for:
- Quarry and mine access roads
- Civil infrastructure and roading projects
- Subdivisions and housing developments
- Forestry and off-road applications
- Any high-traffic site exit or haul road
59% More Effective Than Rock Entrances
FODS Trackout Control Mats provide a durable, reusable construction entrance system minimising sediment and debris tracked onto impermeable roadways. With FODS, contractors can quickly establish a stabilised entrance and relocate access locations as the project progresses.
The system is built with extremely durable HDPE and is designed to last. With a 3 year warranty and a lifespan of 10+ years, FODS mats offer contractors an effective solution for erosion and sediment control.
