How can I tell when my concrete floor is dry?

Hi Everyone,

I have recently moved into a newly built house (march) I am having a solid oak floor laid in the living room but when the fitters came a couple of weeks ago they used a tester and said there was still too much moisture in the concrete. The floor was poured at the end of Feb and I would have thought it would be dry by now but no such luck, anyway I have been running a dehumidifier for the last two weeks and I want to check if it is doing any good, Is there any way to test it without one of the very expensive moisture meters the fitters use,

Any advice greatly appreciated.

    cover an area with some clear polythene , making sure that it is sealed to the floor.You will see a lot of condensation build up over 24 hrs if the floor is still damp...also the guys who tested know what they are doing and its nice to see some pros at work. Do trust them in their judgement as its not in their interest to lay the wood as it will just knacker it
    :confused:I have nothing better to do!!!!:confused:

    Some years ago, staff at the local builders' merchant told me that the drying time for a concrete floor can be in the region of; one month per one inch depth of concrete.

    I doubt you have 7.5cm of concrete flooring!!! unless the contactor wasnt to bothered about costs! so 6 months should be plenty!!!

    I have seen concrete floors which range in depth from 7.5cm (3") up to around 15cm (6").
    So, given that it was poured at the end of February, and allowing for a month or so drying time per one inch depth, the fitters could well be right!

    Theres no way especially with the heat we have had lately that it should take 6 months to dry.
