Concrete slab mold. For more than 50 years concrete slabs are commonly used in the Netherlands as paving on industrial premises because they do not sink in (on a good surface and when well positioned). They are very suitable for paving of outdoor areas, halls and parking lots. The big benefit is that the industrial slabs are laid quicker than paving stones and are very easy to remove, if necessary the surface remains accessible for work on cables and pipes. Concrete slabs are ideal for temporary and / or permanent paving.
