chamferred

[angela beacham]

We are just about to lay some chamferred edge natural stone paving slabs and are being given conflicting advice, narrower edge (the rougher side) up or down?

If I understand you correctly, then it should be "chamfered" side down.

In this picture of an Indian sandstone flag, taken 'edge on'....



....you can see that the edge tapers in - this is known as a 'fettled edge'. The base of the flag has a slightly smaller surface area that the top face, and, you should be able to identify that the top face edge has a definite straight edge, whereas the base is somewhat more haphazard.....




...does that make it clearer?
