So just a tad more than the 75mm depth you were expecting then ? still a good amount of thermal mass now!!
Just worried that it's going to turn into crazy paving all because the builder is an idiot! Said he adjusted it all to suit Lafarge recommendations .... Strange only spoke to Lafarge two days before pour and the sub base , concrete DPC and jablite had been in for some week or two? Me thinks he is a gibbon who cannot measure or calculate such things as ; BOD (bottom of dig ) = FFL - (75 + 150+100+25+150) Gyvlon, jablite, conc, blinding sand , type 1
As for thermal mass it's similar to that of a paper bag and it's inertia could be likened to a carrier bag in a hurricane
