Hi All,
I have a query. We are building a house at the moment, and the builder poured the concrete floors yesterday even though there were downpours all day?? Is this normal? The concrete was poured over underfloor heating that had been placed over insulation on Monday...
I am worried as I thought you had to have dry weather for pouring concrete?
Thanks,
C
Sunny South East: From the OP's post it says its a slab over the UFHIs this stage the screed over the underfloor heating being poured in a "watertight" house, i.e. does it have walls and a roof, or is this the initial floor slab?

I would imagine that the builder decided to do this before any walls as its much easier, just pour and powerfloat
Would be very ususual to pour concrete on UFH pipes infact I have never heard of it before. Concrete is a poor conductor of heat when compared to many of the floor screeds used today
It is more than likely that they used a sand cement screed. Rain on to this finish is never a good idea as it washes the cement out of the sand and then the screed begins to ravel as a result. However a binding agent (the name escapes me) can be poured on to any area that this happens to and this will fix the problem.
We had the same problem when we built our home but all was fine when the builder poured this stuff onto the floors so its not the end of the world and only cost about €60 to put right!
I think you may have picked me up wrong. Concrete subfloor poured then 50mm HD insulation on top then UFH pipes laid on insulation were and covered in a sand cement screed this was flooted off before the walls were risen so floors are perfectly levelWhen we were looking at building methods (2004/2005) I seem to remember that there was a floor make-up which had the UFH under the foundation "slab", but for various reasons this wasn't recommended, the main one being that you'd be paying good money to make the worms nice and warm.

Don't think that is much of a problem in this country for the last couple of wintersotherwise the UFH lag means a sudden hot spell can overheat the entire house.

Looks like it, sorry, I assume everybody else wanted to get the shell done first to get out of the rain!!
