The concrete ballast base is made of steel-reinforced concrete, allowing it to withstand heavy loads while remaining resistant to damage.

The high connectivity allows the individual blocks to be stacked together to form one large block of any weight. The connectors allow for both horizontal and vertical connections. Due to its compact dimensions (800x800x40 cm for the 500kg and 1200x1200x40 cm for the 1250kg) and stackability, transportation is simple and e icient. For handling you can use the hanging point in the middle of the block or the pocket ready for the forklift. Adjustable “spindles” with a large contact area can be used on uneven surfaces.
