how long to dry wet floor?

[legepe]

Hi all
After having a water leak several months ago I have had all the laminate floor lifted for almost 3 weeks and have had a dehumidifier working for amost 2 weeks, but the floor is still showing it is wet (see attached pics)
It is a floating floor consisting of - 22mm moisture resistant chipboard / 30mm insulation / Visqueen / Concrete
First pic shows roughly the readings from where its been effected with water, and the second pic is showing reading from a known dry area of floor
Does any one have expericence with this, and know how long it takes to dry out? before being able to lay new laminate?
Any advice much appreciated

Heat would help, moisture needs to be airborne for dehumidifier to work. Fan heater ?.

Just a fan will help if its warm.
Run dehumidifier and a fan to move air.

Introduce some heat if it below room temperature but otherwise you should be fine. Days are warm. All the concrete outside is dry

Thanks guys..! its a bit out of my own control as I have given the tenants the dehumidifier and told them heat and air circulation is the only way.. but not sure if they are doing it?? just seems to me to be taking too long to show dryer readings, but I have never had this problem before, my thinking with the dehumidifier is that if there is less moisture in the air then it should force it out of the floor more quickly, no??

Heat can just create humidity that then condenses on a cold surface. It's just a circle. You get nowhere.
You need movement of dry air.
Then need somewhere for the moisture to go. Either out the window or in the dehumidifier..

If your tenant is picking up the electricity bill they may not be heating, and dehumidifying whilst circulating the air. The weather for the next week is supposed to be good. Get the windows open to ventilate.

Ventilation is the key to this

That is exactly what they are doing at the moment, just hope the weather stays dry warm and windy
