Tegula®-Tec

A new concrete paving stone system with horizontal and vertical interlock below the surface. In the tumbled version, Tegula®-Tec offers a nostalgic appearance. In the untumbled version, an extreme smooth surface yet both versions guarantee a strong distribution of rolling and shear loads which develop from accelerations or decelerations at intersections, traffic lights or on slopes.
