thanks for your reply, can you clarify about the rain fall? are you saying a 100mm dia pipe is not large enough for 500m2? i was planningfor it to take the roof water as well thats about 1500m2! how do i speak to the gaffer, phone?
thanks

Quick calculation but at 100mm rainfall per month, 300m2 would get you 30,000L of water.

that doesnt sound like a lot, imagine 30 x ibc containers being emptied via a 4 inch pipe over 30 days. the suds storage we have for the site is 260m3 or 260,000 liters and that is fed by 6 inch pipe and emptied by 6 inch pipe. we have a car park which is to be emptied by 6 inch perforated pipe and the car park is 2000m2. these are engineer calculated values. in my opinion the most i would have to do is replace the 4 inch pipe for 6 inch pipe which is no big deal.

You need to work around extremes though. You could have 1 months rainfall in 1 day. Lets say you drain the roof there as well, 100mm rainfall in 1 day (which isn't that extreme) 1500m2 and you have 150,000L going in 1 day.
Take that example to the extreme, using the record for 30 minutes of rainfall in scotland (80mm) and it is 120,000L in 30 minutes.
I'm not an architect, engineer, weatherman etc but I do think you need to look at what you're doing more carefully, especially if you are proposing luxury flats with a luxury price tag.

i made a slight error, its less than half the roof draining this way so i would be closer to about 1100m2. been draining ok so for the last 200 years
click on the link i sent you
better to spend a few quid at this stage than crack on blindfolded into the abyss :;):
generally speaking especially in a wet place like scotland you do not want to be increasing levels without good cause
natural stone beats concrete block paving every time on period properties but budget is always lurking
in principal is it ok to lay on concrete? forget about the levels for the moment. should the blocks go straight onto the concrete or should they be glued down with some type of tar or cement?

If it is concrete sub base then need some sort of bound material for laying on.
The court yard in my opinion is the focal point of each property and needs to be a pleasant place to greet your neighbours every evening / morning and this will be the main selling point for each of the property as it's kinda a communal dwelling really. I think there has to be some area for soft scraping and discrete seating maybe a small raised feature in the centre? I think a mixture of symetrical paving and well thought out design will Finnish the project and set it apart from other property's when it comes to parting with cash. There is always a solution to any problem in regards to drainage but I would rather gravity help where possible. Phone me to discuss your requirements and I'll see if I can help.

its got 12 car parking spaces in it and the center area is the road in and out. i dont think a raised seating area would work, did you look at the plans? they are in an earlier post. thanks
I've had a good look at the photo's and I think you're going to have to remove the concrete it looks as though it's level with the house thresh holds and also because the service trenches have been dug so wide ( could you not find a smaller bucket) you're going to have settlement issues with your backfill unless you lean mix it. Laying block paving on large areas of concrete can lead to water pumping so you'll either need to drill lots of holes or add a fin drain. I live in a building of similar construction and I can guarantee you'll get damp issues if you fall the water to the building or don't reduce the levels. The stone found sits on clay if you run the water through a perforated pipe it will saturate it which could cause heave and if you get a very dry summer it could shrink and contract either way the building will be in trouble also the pipe is likely to silt up very quickly after. Don't think that because it's been like that for so long it's ok this is the first time modern methods and materials will have been used in it whereas before any damp and cracking wouldn't be an issue due to who would've lived or worked there. The stone at ground level looks very wet in places if you maintain a high finished level then it won't dry out. I'd strongly suggest not installing grass it won't grow well in such a setting and there's the issue of who cuts it well planted shrub beds would be more suitable. If I were to do this on a budget I'd invest in nice granite kerbs and sett trim and then lay asphalt with a grey chip. I'd also use the setts to mark each parking bay.
i dont think the council will accept tarmac. ive already told them it will be some type of block paving. i couldnt use a smaller bucket, thats the smallest i have for my machine and we needed the trenches that big. add concrete to the trenches is no problem. you cant see the floor level of the flats but it is much higher that what you can see. the bit you can see hasnt been raised yet. does anyone know the best place to see aura paving from brett? where is the best place to buy this aura paving ?
thanks

the best thing to do jack is to go to a local BM and get some samples
stuff in catalogues doesnt always look the same in RL
with a decent sized order like yours they may even send you samples
LLL
thats about 1500m2! how do i speak to the gaffer, phone?
