I am about to lay a concrete floor in my kitchen. It will cover
underfloor heating pipes. I was planning to use cement, sand and
aggregate but have been advised to use "chippings to dust" and cement
as it is easier.
what do you think and what are the pros and cons?
Chippings to dust will not bond well to form concrete (because of the dust)
and is used for the hardcore sub-base only.
well compacted soil
100mm compacted hardcore
20mm sand blinding
60mm Insulation (silver foil backed to reflect heat from pipes)
50mm screed (or as per heater pipe manufacturer recommendations)
