Concrete floor drying times

werenotthere

Finishing a total renovation of a house in wicklow in the next month.
Having some problems with drying times of the concrete at ground level. We put down 15cm. Moisture readings are not at the required levels for flooring. Anyone have any ideas how long it will take in this weather? Concrete was poured at the beginning of November. Builder doesn't want to give me a straight answer

Hi guys wondering if someone can help?

Doing a total refurb of a house in wicklow. Concrete floor was poured at the beginning of november to a depth of 150mm.

Cant get the correct moisture reading to lay the floor, anyone have any idea how long this should take at this time of the year? Builder wont give me a straight answer

1 mm per day

Roughly dries out at 1mm per day. So in your case that's approx 150 days from pouring. Are you tiling the floors?

Seal up the house as best you can and get in the dehumidifiers for a few days. There’s little or no drying in this weather without them.

What’s the floor?
There are dpc products you can put down if required.
As Syd says 1mm per day, but if it was down in nov, the question is what temp / how ventilated and how dry was the house since?

if using de-humids, don't over do it else you may warp door frames etc

To be fair it's impossible for the builder to accurately say how long it's going to take to dry out. Have you underfloor heating? If you can use that but on a very low heat and very slowly increase it. This will help a bit.

Don't rush it anyway or the floor covering will get destroyed, have to be taken up and redone costing thousands.
