Zeffo77 Posted May 31, 2020 Share Posted May 31, 2020 Hi I am going to build a 2-tier retaining wall for my driveway. 8m in length. The higher tier will be 1.1m. The lower tier will be 600mm. I am looking into drainage behind each wall and it looks like a french drain is my best option. But I do not know where to outlet the water. I cannot let it come out onto the pavement so could someone please advise on what I should do. I have attached a picture of my drive currently. Thanks.

scottishjohn Posted May 31, 2020 Share Posted May 31, 2020 Maybe me being thick but why to what purpose do you want to divide up the area for neither side have tiered front areas ,so you will be needing to build end walls as well Link to comment Share on other sites More sharing options...
Russell griffiths Posted May 31, 2020 Share Posted May 31, 2020 I’m a bit baffled what is it retaining. Link to comment Share on other sites More sharing options...
Declan52 Posted May 31, 2020 Share Posted May 31, 2020 You look like you already a perfectly decent area to park enough cars on why go to all that expense and for something that size it will be a fairly big expense. Link to comment Share on other sites More sharing options...
Temp Posted May 31, 2020 Share Posted May 31, 2020 What's under the sheets? Looks like you have weed suppression sheets down. If you want to level and pave or tarmac the front you should probably put a soakaway under it first. These days if you don't deal with rainwater run off on site you will need to make a planning application. Link to comment Share on other sites More sharing options...
Zeffo77 Posted May 31, 2020 Author Share Posted May 31, 2020 We want to level out the driveway for 2 reasons. 1. My parents live with me and it's getting harder for them to navigate the slope. 2. Kerb appeal. It looks unfinished at the moment. When I bought the house it was similar to my neighbors drive (image attached). We cleared it all thinking it would be better with an entrance/exit in the middle. That isn't the case anymore so want to have the driveway level in line with the front door height, 1.1metres.

Temp Posted May 31, 2020 Share Posted May 31, 2020 If the soil is permeable a soakaway under the parking area would be the best option. You should also read.. https://www.planningportal.co.uk/info/200130/common_projects/45/paving_your_front_garden Planning permission Specific rules apply for householders wanting to pave over their front gardens. You will not need planning permission if a new or replacement driveway of any size uses permeable (or porous) surfacing which allows water to drain through, such as gravel, permeable concrete block paving or porous asphalt, or if the rainwater is directed to a lawn or border to drain naturally. If the surface to be covered is more than five square metres planning permission will be needed for laying traditional, impermeable driveways that do not provide for the water to run to a permeable area. In short you need planning permission to tarmac, concrete or pave a front garden unless you deal with rainwater run off on site. That usually means drains to collect rainwater and a soakaway but if the area of hard surface is small and the soil is very free draining you might get away with sloping the ground towards flower beds. The thing to avoid is rainwater running down the driveway onto the road. Link to comment Share on other sites More sharing options...
Zeffo77 Posted June 3, 2020 Author Share Posted June 3, 2020 (edited) Hi all. Please find designs attached. We are leaning towards having the design with the stairs on the right hand side. If anyone can help with my original question regarding drainage, please do. The second wall, which is the highest, will be 1m so no need for planning permission. We plan to have gravel on the driveway. Edited June 3, 2020 by Zeffo77 Adding extra info Link to comment Share on other sites More sharing options...
tonyshouse Posted June 3, 2020 Share Posted June 3, 2020 You will need foundations, let’s say 450 deep, concrete, and I think protective railings on each level, I would dig a soak away 3m back in the middle 2m deep and run land drains back to it that link to perforated pipes that run behind the bottom of each wall. how about Gabions, plonk em down, done, cheap, easy paving slab steps between two of the.

Mr Punter Posted June 3, 2020 Share Posted June 3, 2020 In your other thread you were looking at sleepers and I suggested this could be achieved fairly easily with no drainage issues. Link to comment Share on other sites More sharing options...
