The high-end riding arena grid

The multifunctional riding arena grid ECORASTER TR40 with storage. Newly incorporated water storage cells collect run-off and return it to the footing in periods of dry weather. This means up to 5 l of water per sq m can be stored. With its new geometry and new improved formula, this grid sets new standards in terms of ride, stability and safety.

Due to a revised formula

By incorporating high-quality aggregates, the new ECORASTER TR40 is even more elastic and flexible.

Valuable resource conservation

The water reservoir cells store up to 5 liters per square meter and enter this gradually to the treading layer.

TÜV approved

Simple and easy to handle, the TÜV-approved locking system ensures stable and safe cohesion of the grids.

Riding comfort in a new dimension

Developed by scientists and professional athletes and perfectly adapted to the needs of the equestrian sport.
