New project - Drainage and frost

[intercityuk]

Sorry computer problems, anyway as usuall you are all correct CBP it is then ( on the credit card ).

Anyway got most of old concrete out and flags should be getting mini digger next week. Some photos before i ask the questions http://www.facebook.com/album.p....30464a6 as you can see i have 3 drains in total one round the back and one at each corner of the house.

All the drains are at the house side so i was going to create a channel within the paving with a soldier course next to the house does this sound ok ? the top of the paving will be above the drains. I could have a linear drain at the otherside of the drive but when it gets to the path outside there is no where for the water to go.
45degree herring bone with a soldier course all the way round is what iam thinking any advise very welcome.

Cause its getting cold now ( i live in the mountains ) iam worried about two things 1) Does it matter if the bedding layer of sand gets wet before i have got all the cbp down and compacted? 2) Is it ok to put the kilm dried sand down and compact even when it is frosty and will frost effect the bedding sand?
thanks sorry for the long post !

I'm sure this must have been covered before, but damp laying course sand is OK, but if its sopping wet or saturated, it needs to dry off, and as for the jointing, you just don't lay, compact or joint when the ground is frozen.

Thanks very much Tony, would my drainage method be ok ?

cheers

Yes, I see no problem with it but I'd far rather see a run of aco drainage.....but if costs are a priority, then go for it.

Running surface water over a pavement in an open channel risks scouring the jointing. I'm with Dave: I'd prefer a linear channel, but as I'm not familiar with the site, I can't really say what would be best.
