Laying an indian sandstone patio on Tuesday. Approx 40m2. I was going to aim for a crossfall gradient of about 1/60 which over the length of the patio from the house outwards is approx 11.6cm.
Was just wondering how strict I have to be with is. I have several holes in the patio where raised planters will be positioned etc etc. If I put in a slight end fall towards the planters can I get away with reducing the crossfall or would this be too risky.
