Paving slab for laying on sloping ground has inward sloping edges to retain spacing gap when laid on uneven ground

摘要

An improved design of paving slab has a decorative top layer and a supporting main body. The edges of the slab have a vertical profile at the upper part and an inwards sloping profile for most of the lower part. The sloping profile is provided all round the slab and enables the slab to be laid onto a convex slope without altering the spacing slot between the slabs. This ensures that the appearance of grouting material is even over the paved area.
