My drive had a post which fell down leaving a clean break. I've chosen not to place the post back in, but instead fill the hole with Concrete Block Paving. I got hold of Concrete Block Paving 200mm x 100mm x 50mm. The 50mm is slightly high, leaving a slight bulge. I could not find Concrete Block Paving 200mm x 100mm x 40mm. I do not want to smash and dig the ground deeper in order to fit the 50mm block paving. Is there another solution?, do shops even supply 40mm block paving?
thank you
