Laying LVT over concrete slab

[stereo_rob]

Hi I hope someone can offer some guidance here. Im in the process of converting a garden shed 12 x 9 into a cabin for the wife to work from. We are at the stage of deciding on flooring and she would like LVT, the current slab is 50mm type 1, damp proof membrane, then 150mm concrete slab (cured for 6 years). There is a small corner of the slab showing a bit of damp which now means I have to do something before the floor goes down.

Question - The slab is marginally unlevel (+-5mm) end to end, I would imagine I need to use some self leveling and a epoxy dpm, what is the process to get this to the stage where I dont have to worry about damp under the LVT, any recommended products etc.

Thankyou for your help
