This is one for those with the technical knowlege of building requlations!
In a situation where there is a raft foundation and 600mm to finished floor level is there a requirement for a sub floor to comply with building regulations?
Would the following build up comply -
300mm Raft foundation
355mm well compacted hardcore
20mm sand blinding
Radon barrier
150mm insulation
Underfloor heating pipes
75mm finished screed
Thanks.
