Underlayment and Moisture Barrier in West Middlesex, PA
Underlayment is invisible once the floor is down and it decides how that floor sounds, feels and lasts. It levels minor subfloor variation, deadens sound between storeys, and in the case of a moisture barrier it stops vapour rising out of a concrete slab into the flooring above.
Concrete passes moisture continuously, including slabs that read completely dry to the touch. Installing over a slab without a barrier is how floors cup, adhesive fails and laminate swells from underneath months after a faultless installation.
Hardline Surface Co. tests and specifies across West Middlesex, PA before anything is laid.
One thing worth knowing: many click-lock floors arrive with a pad already attached to the plank. Adding a second underlayment beneath that is too much cushion, and the joints fail because the planks flex more than the locking system tolerates. More is not better here.
