Hi, I have a very small concrete area at the back of the house that extends onto lawn. I want to lay a patio and raise it a bit. Have just removed a concrete path that went alongside the garden and would like to use that material. As I understand I need a layer of hardcore and sand on top before placing the slabs on top? Is this correct?
I am planning on leaving a 4cm gap between the fist slab and the house wall which will be filled with pebbles.
I will also be securing a border around the patio area to stop slabs moving as I dot want them concreted on to the ground.
If I use the broken cement, do I have to break it into smaller pieces and compact it before adding the sand? or can just I just fill the are with the hardcore as best I can and then fill the gaps with sand and then add more sand on top to flatten the area before placing slabs down?
I am doing this right?
Many thanks,
