I'm laying some porcelain paving from the rear of my house into my garden to meet an aco drain just infront of sleeper steps onto our lawn. The acp drain is set lower to accommodate a 1:60 fall.
My question is how do I ensure that my paving ends up a couple mm above the top of the aco drain? all I can think of doing is running string lines either side of the paving to make sure it meets the drain, but can't think of what else to do?
