Hi all. Would appreciate some advice on the planning of this project.
House is about 20 years old and has a conservatory that's about 15 years old. The conservatory is square and about 4m across and is constructed with about 7 courses of bricks with UPVC/roof on top. The conservatory is surrounded by a patio varying in width from 1.5 to 2.5 metres. The patio is bordered by a brick retaining wall that leads to the lawn.
The the patio has only a single drain approx 15cm diameter that I guess should be going into a soak away. The drain is completely ineffective for two reasons:
1. Having excavated the drain to investigate it terminates almost immediately below the patio in the sticky clay soil-no soak away. Pouring a couple of litres of water in saturates it.
2. The patio is essentially flat and water just collects in random large puddles.
I'd like to add some decent drainage. I'm thinking about using the Aco Hex drain system. Lift the patio and relay it, maintaining a the existing 2 course of brick gap between the patio and DPC, with some slope so the water drains into the Hex Drain. If this seems like a reasonable plan, would the slope be best engineered to have water run away from the conservatory towards the wall and into the Hex Drain that would be installed immediately next to the retaining wall rather than the other direction?
Thanks for your consideration
