How I extended an existing patio in front of a new ground floor house extension. I talk about matching the the new slabs with the originals and keeping the pattern random. It also tells how I put a curved wave in the edge to match other curves and create a pleasing shape to the patio.
I recently spent half a day removing block paving moss from my driveway. The paving, laid in 1993, has been cleaned more than once but moss soon grows under damp conditions.
Because the blocks have a chamfered edge there is a V shaped recess at the junction between blocks. This is a space where moss can grow, and boy does it grow. In this recess moss doesn’t get worn away by traffic (cars or feet).
