Laying Laminate on new concrete floor..??

I'll be laying laminate soon in a new house. I have to move quick on it cos I need to turn it around fast for rent.
Chances are the concrete will only have been poured a couple of weeks so it probably won't be fully dried out.

If I lay an underlay with a damp proof course, will the floor still warp with the moisture drying out from the concrete?

• The moisture content of the concrete may not exceed 2.5 % (CM method). A freshly
poured coating must dry out for at least 1 week per cm (3/8”) thickness up to 4 cm
(1”1/2), and 2 weeks per cm (3/8”) thickness above 4 cm (1”1/2), with sufficient ventilation.
(6 cm (2”1/2) concrete must therefore dry out for a minimum of 8 weeks).

hope this helps i think you can buy dampproof underlay but i've never seen it

(this is for quickstep flooring)
