With the use of special tractor, the application speed is up to 6000 m²/hour. For manual installation, it is approx. 1000 m²/hour.

Under what weather conditions cannot the geogrid be applied?

Local standards and regulations for application of asphalt surfaces (e.g. temperature, precipitation, humidity) must be observed. We do not recommend the application of geogrids at air temperatures below 5° C and when raining or after the rain when the surface is still wet.
