What is the difference between the construction dimensions and the product dimensions of paving stones and slabs?

Paving stone and slab construction dimensions are what we give in our product catalogues and on our website. The construction dimensions are vital when planning (or laying) an area that is to have paving stones and/or slabs. This is because these dimensions include the recommended joint width of 3 mm.

Product dimensions are the paving stone’s or slab’s real length and width excluding any spacing. The product dimensions are not given in any of our product catalogues or on our website. They are not useful when planning (or laying) an area that is to have paving stones and/or slabs. The tolerance requirements in Swedish standards are in relation to product dimensions.
