Installation details such as slab footing junctures are key to a quality install.

Best moisture barrier for concrete floor.

Flooring moisture barriers are placed beneath the floor s underlayment. 15 mil vapor barrier by americover. This is because concrete subfloors release moisture which can be very damaging if absorbed by the laminate planks. The damping agent creates an impermeable layer and hence keep moisture in concrete slab.

In this method damping agent such as liquid epoxy damp proof membrane is applied for an existing concrete floor system. Moisture in concrete should be measured by an anhydrous calcium chloride test kit per the astm f 1869 test method or by using an in situ probe test for relative humidity rh per the astm f 2170.
