Underlayment and Moisture Barrier in Saint Louis, MO

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 Saint Louis, MO 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.

Underlayment And Moisture Barrier FAQs

Frequently asked questions about Underlayment and Moisture Barrier

Questions we hear most often about Underlayment and Moisture Barrier in Saint Louis, MO.

Talk to a real person
Can laminate go in a bathroom?
No. The fibreboard core swells permanently once water reaches it, and swollen laminate can only be replaced, not dried or repaired. Use sheet vinyl, waterproof LVP or tile instead.
Why does my tile quote include floor preparation?
Because tile cracks on an uneven subfloor, and large format needs flatter than most people expect. A quote without preparation is not cheaper, it is incomplete, and the cost arrives later as failed grout and lifted corners.
What is the PEI rating and why does it matter?
It rates a tile's surface wear resistance. PEI 1 and 2 are wall tiles, and putting one on a floor wears the glaze through. It is a common and completely avoidable mistake.
What is the difference between SPC and WPC core?
SPC is rigid and handles an imperfect subfloor better. WPC is softer underfoot and quieter. Since very few subfloors are genuinely flat, SPC is the safer choice more often than not.
How do I get an estimate in Saint Louis, MO?
Call (888) 928-6413 for an in-home measure. Samples come to you and we check the subfloor while we are there, because the subfloor decides half the specification.
