EcoGrid Steel Fixing J Pins are used to add a security measure to installations where stability may be in-doubt. The Bloxx system is designed for use in conjunction with EcoGrid's grass or gravel filled paving system or as a "stand alone" system for permeable solid hard standing.

For example, steep gradients. Pinning the EcoGrid down will avoid the potential movement issues. The frequency tends to depend on the situation, but three pins per square metre will usually suffice. With slight gradients EcoGrid will remain stable and secure without ground spikes or pins.
