Stag 2

Put in Hardcore or dolomite is another phrase this goes in at 6 to 10 inches deep whilst wacking it every few inches, this has to be done very precisely to ensure drive or patio does not sink in future depending on what the consumer wants. For example Resin, you'd have to tarmac on top of the hardcore, this is at a depth of around 60 to 100mm thick, this is to do a base for the resin to bond to. Again customer's preference to edge the resin block paving can be used so these go in before the tarmac to create a border, then the tarmac is recessed approximately 20mm from the top of the block creating a space for resin.  The resin will fill the remaining space or simply trim edge is always a nicer finish with blocks(d)

If the customer needs a step into threshold you'd use boot kerbs(e) to create perimeter of the step and then resin of block in the centre. If customers want blocks and not resin instead of tarmacing on hardcore, you'd screed sharp sand and then block the top.
