My mum was quoted for a patio. I want to check if the procedure that was outlined sounds ok
1. I have an existing patio which I want to extend to double its size. Can I use it as a base for the new patio? If so, how much of a mortar bed should I allow?
2. Should i dig out the additional area to 75mm below existing slab level for type 1 (compacted)?
3. is 4 sharp sand to 1 cement, semi dry mix ok for bedding new slabs over existing slabs?
4 The new patio level will be raised to 2 to 3 inches below the dpc. If i put a french drain between the patio and house, how wide and deep should it be?
