Waterproof Flooring in Louisiana &...

Why Waterproof Flooring Is a Different Conversation in the South

If you live in Shreveport, Bossier City, or anywhere across northwest Louisiana and East Texas, you already know what the climate does to a house. Humidity doesn't stay outside. It works its way into subfloors, swells wood, loosens grout, and causes problems that homeowners don't notice until they're expensive. Waterproof flooring is one of the most searched topics we get questions about — and one of the most misunderstood. This guide is the honest version.

What 'Waterproof' Actually Means (And What It Doesn't)

The word waterproof on a flooring label refers to the finished plank or tile itself — not the system as a whole. A 100% waterproof LVP plank will not warp, swell, or absorb water if it gets wet. But that doesn't mean you can ignore what's underneath it.

The subfloor, the moisture vapor coming through a concrete slab, and the way seams and transitions are handled all determine whether your floor performs the way the label promises. We've seen waterproof LVP fail in Shreveport homes not because the product was bad, but because moisture was wicking up from a concrete slab and had nowhere to go once the floor was sealed over it.

Waterproof means the plank. Moisture management means the whole system.

LVP: The Best All-Weather Option for Most Louisiana and East Texas Homes

Luxury vinyl plank is the most popular waterproof flooring choice in our market, and for good reason. It handles humidity better than any wood product, it's scratch-resistant, and it installs well over concrete slabs — which is the foundation type in the majority of homes we work in across the Ark-La-Tex region.

Not all LVP is created equal. The key specs to ask about:

Wear layer thickness: 12 mil minimum for a household with pets or heavy foot traffic. 20 mil for commercial-grade durability.
Core type: SPC (stone plastic composite) is more rigid and more dimensionally stable than WPC (wood plastic composite). For slab-on-grade homes in Louisiana, SPC is generally the better choice.
Locking system: Click-lock systems are standard and perform well. Glue-down is sometimes appropriate for specific subfloor situations.

We work with homeowners across Shreveport, Bossier City, Haughton, Greenwood, Blanchard, Keithville, Stonewall, and throughout East Texas. The SPC-core, click-lock LVP with a 20 mil wear layer has been the most consistent performer across all of those markets.

Porcelain Tile: The Other True Waterproof Option

Dense-body porcelain tile with proper grout sealing is genuinely waterproof at the surface level. For bathrooms, laundry rooms, and kitchens, it's an excellent choice. The important caveat: the tile is waterproof, but the grout and the installation behind it determine the long-term outcome.

We use Schluter® waterproofing systems on every tile shower and wet area we build. The membrane goes behind the tile and handles the actual waterproofing — the tile protects the membrane from physical damage. A shower built without a proper membrane, regardless of how expensive the tile is, will fail. That failure just takes three to five years to become visible.

For Shreveport and Bossier City homeowners planning a bathroom renovation, ask any contractor specifically what waterproofing system they use behind the tile. If they don't have a clear answer, that tells you something important.

What Doesn't Work in Our Climate

Solid hardwood in high-humidity spaces: Solid hardwood is beautiful and it's still the most requested flooring upgrade we get. But solid hardwood on a slab-on-grade foundation in Louisiana is a high-risk combination. It expands and contracts with humidity changes, and in a climate like ours, those changes are significant. We install solid hardwood in East Texas and Louisiana homes regularly — but only in the right conditions, with the right subfloor prep, and only after thorough moisture testing.

Water-resistant (not waterproof) products in wet areas: There's a meaningful difference between water-resistant and waterproof. Water-resistant flooring can handle a spill if you clean it up promptly. It cannot handle a slow refrigerator leak, a bathroom that gets steam every morning, or a laundry room with a washer that occasionally overflows. For those spaces, waterproof is the only appropriate specification.

Any flooring over an untreated moisture problem: No flooring product — waterproof or otherwise — can compensate for a moisture source beneath it. Before we install any floor in any home across Shreveport, Bossier City, Tyler, Longview, or the surrounding areas, we test the subfloor for moisture. If we find a problem, we address it first. Installing over it just seals the problem in and accelerates failure.

The Moisture Test: Why It's Non-Negotiable Here

East Texas and northwest Louisiana have some of the highest average humidity levels in the country. That means moisture testing before flooring installation isn't a courtesy — it's the baseline for any responsible installation.

For wood subfloors, we use calibrated pin-type and pinless meters to measure moisture content. For concrete slabs, we test moisture vapor emission rates. The results get documented and shared with the homeowner before any product goes down.

This step takes time. It sometimes means we have to wait, or address a problem before we can start. But it's the reason our floors hold up in conditions that can be punishing on inferior installations.

Which Option Is Right for Your Home?

The honest answer: it depends on the room, the subfloor, and how you live. Here's how we generally think through it:

Slab-on-grade foundation, high-traffic areas: SPC LVP with a 20 mil wear layer
Bathrooms and wet areas: Porcelain tile with Schluter waterproofing, or waterproof LVP
Living areas where you want the warmth of wood: Engineered hardwood (properly acclimated and installed with a moisture barrier)
Historic homes where authentic hardwood matters: Solid hardwood, in the right conditions, with full moisture prep

We serve homeowners across Shreveport, Bossier City, Haughton, Greenwood, Blanchard, Keithville, Tyler, Longview, and across the Ark-La-Tex region. If you're not sure what's right for your specific home, we'll come out, test your subfloor, and give you a straight answer.
