Patios: to slope or not to slope
Just wanted to ask a quick question about patios and whether to slope them or not. I understand that a patio up against a property needs at least a 1 in 60 slope (1cm fall for every 60cms) to allow for rain water to run away from the property but what about those in lawns?
I am looking to build a 2m x 2m patio in my lawn which has grass on three of it's sides and about 15 - 20cms of soil at the back of it by a neighbour's fence and shed.
I was thinking about having a 1 in 60 slope running from the fence to the grass but it works out to just over 3cms (one whole paving slab) and I feel it would be quite severe and odd looking not to mention a whole lot more hassle!
I've asked a number of people and had answers ranging from a slope isn't necessary for my patio to maybe just having a small one of 1cm or so.
What do you guys think? Attached is a photo to give you an idea of the position.
Thank you in advance.
