MUST MY PAVING AROUND HOUSE BE 2 BRICK LOWER THAN DAMPCOURSE

[Nicetoseeyoutoseeyounice]

After getting a few quotes last week for paving around house and patio I agreed on a person who is actually specialises in this and who's quote was acceptable. He, like the others agreed that the paving flags should be 150mm or 2 brick lower than dampcourse but because the garden sits slightly higher than the flags then any rain would run to end of paving and pool by grass edge, so, the flags would have to run to grids by house. Now thats ok but after him starting today and laying quite a lot of the paving it now its only 1 brick lower than damp course. They do all seem to run towards grids but I dont know if this would be ok as I thought they had to be 150mm lower. Will this alright or do I have to tell him tomorrow. I'm afraid that if we come to sell any surveyor would say the flags had to be lifted and relaid 2 brick courses lower than dampcourse. What should I do?

a surveyor will spot this like an angry boil.

Thought as much. Have since, spoke with person doing work and he agrees but the problem seems to be the existing grids. He is going to take all flags up tomorrow and lower grids as best he can and then relay. So am I right is it definately that they should be laid 2 bricks or 150mm lower than dampcourse. All replys appreciated.

the other way around it is to leave a 4" margin around the paving where it abuts the house and backfill with gravel/slate etc, so that there is a free draining area. Can look effective and certainly building control in our area are happy with that.

If he originally agreed to install it 150mm below dpc level and now he's not surely he should redo it?

i agree with you freddy, just saying that there are other ways around it

Right so the builder has now removed all the paving flags fitted yesterday and the drain has been lowered. I am now left with the option of:

1. Relay paving and allow rain water to run to garden, bearing in mind garden is slightly raised.

2. Relay and allow water to run into 2 grids which are close to to house (kitchen sink drain and bathroom sink drain).

If water ran towards slightly higher garden area then obviously it would pool along there, but I feel this can be solved later by adding a gully etc. Or, should it just drain to grids.

All answers appreciated.

A new drain in the right place would doubtless be the best solution but if you don't want to do that and you don't want it pooling you'll have to use the existing drains. Seems obvious really. Theoretically may be a breach of building regs but there you go.

Well its now all finished, didnt opt for the running off to drains bit and opted for the slope away from house, I know it can be very rare but I have seen drains blocked or either just cant cope with the amount of water going down them and this would definately lead to a lot of pooling around the house, oh course I will now get some pooling at edge of paving where garden area is slightly higher but will now cut away edge of grass and form some sort of gully and maybe fill with gravel this would not only look quite nice but would also allow any water to soak away leaving the brickwork around my house free from any pooling (hopefully).
Thanks for all your replys.
