I am just about to start laying my slabs but I had no plans to put drainage in. It is about 30m's. Do I need to put drains in or not. The only option open to me is to dig out a soakpit.
I have never seen drains in a patio around a house before that's why I felt I didn't need any.

Depends on the ground conditions, Fergus. If you're on heavy clay and prone to waterlogging, then drainage into the SW system is the best solution, but, if a soakaway is your only option, it will have to do.

At 30m2, you need to think about where you will send the water. It all depends on the layout - a 5x6 patio, with only 5m against the open ground, could struggle to drain in heavy rain, while, at the other extreme, 18x x 2m with 18m against the garden should drain into the garden fairly simply.

Tell me what the ground is like....

PS - you don't have a young daughter by the name of Roisin, do you?

Tony I don't have a young daughter called Roisin, why do you ask.

The patio is being laid up against the footpath from the house. It is approx 7m x 4m with the seven along the edge of the footpath. The ground condition is hard and gravelly and drains well.

I am going to lay the slabs on a mix of 8x1 mix of sand and cement(the sand is builders sand), will this be ok.

The ground sounds as though it will be OK, fergus. Just make sure you create adequate falls with the paving to get the surface water to a free edge.

The Q about Roisin is because a young lass by the name of Roisin Byrne from Co Wicklow, has been emailing my daughter, Roisin, about her website, and I wondered if you were her Da. :)
