Under Floor Heating

[quality]

Please could some body advise me on instaling under floor heating or rather the make up of the actual floor construction for a work shop that will have vehicles parked in it.
I have done this before in a house for foot trafic but never for a workshop that could have a 1.5 ton van parked on the floor.
thanks in advance

if the floor is strong enough to take the wieght of the vehicles i cant see it would affect the underfloor in any way unless someone can point out diferent

check current building regs for insulation in sub floors with under-floor heating . good insulation, good covering of screed great job!
