Hello,
We’re getting quotes to have a new patio laid and SWMBO has chosen 900 x 600 x 20mm thick R11 porcelain slabs.
One of the quotes states excavation to a minimum depth of 170 mm, with a sub-base of 80-100mm compacted hardcore scalping sand and then 50-70mm of concrete.
Does this sound reasonable? It’s for foot traffic only (no vehicles) but we’re on heavy clay soil and I don’t want to risk any movement.
The quote also states the use of EasyPrime and FlowPoint which appear to be suitable products?
Is there anything else we should be aware of and/or ask the installer?
Thank you
Davey
