How close can I pave to Homeguard DPC

Page 1 of 1
Hi All,
Have had conflicting advice and was wondering if anyone had definitive knowledge of how close I can pave to the homeguard DPC installed on my slab...is it 75mm? or can it be less than this...

any help appreciated

thanks

I would say 75mm is the minimum.

150mm is better as it also helps protect against damp getting into the slab.
thanks bashworth, the advice I'd been given was that it could be less than 75mm undercover (we have a verandah area that the paving is going against. The Homeguard DPC is on top of the exposed slab and really wanted to avoid a step down from the external doors if I could. Paver said they would waterproof the slab where the paving went against the house, so wanted to clarify how close they could go to the DPC).
I'd read somewhere it was 50mm if undercover but wanted some confirmation...or not!
Hi guys

Just wondering if anyone has exposed slab on their house.
We have it on the right hand side of the house. (see picture)

Anyone know whether this is ok or should I be worried?
