Paving on top of DPC

[Rich101]

hi,

I have a garden that sits on top of an underground car park. In my garden there is a DPC membrane covering the entire surface area also coming up the side of the property. Previously this was covered by about 80 sq metres of decking. I’m now ripping up the decking which is rotten through.

I’m not keen to replace the soft wood decking like for like, nor do I want to fork out for hard wood / composite decking and would prefer paving.

Are there any particular regulations or best practice standards around this I should be aware of?

Thanks

As long as surface water can get to wherever it needs to go then I can't see a problem in the water sense, though you may need a grit bed and open grit jointing to allow water to travel.

80m2 of standard paving will weigh around 8-10 ton plus the bedding material which will add another 4-6 ton so that needs to be checked , though I suspect the car park is more than upto the specified requirements.
