Laundry Waterproofing Systems

Laundry waterproofing protects one of the most moisture-exposed areas in your home by creating a continuous waterproof layer beneath flooring and finishes where washing machines, sinks, and plumbing connections are present. ProLux Materials laundry waterproofing systems include bonded waterproof membranes, waterproof boards, sealing tapes, and accessories that work together beneath tile or panels to prevent water from reaching subfloors, wall assemblies, and structural materials. Installed under finished surfaces, these components help manage spills, humidity, and leaks while supporting long-term moisture control in laundry environments.

Protect Your Laundry Room with Waterproofing Solutions

Laundry rooms are frequently exposed to water from washing machines, utility sinks, plumbing connections, and occasional overflows. Without proper waterproofing, even small drips or standing water can migrate through seams, grout lines, or unsealed surfaces and reach subfloors, framing, or concealed wall cavities, leading to mold growth, staining, and structural damage.

ProLux laundry waterproofing systems use bonded waterproof membranes, waterproof tile backer boards, waterproofing tapes, and finishing accessories to form a continuous moisture barrier beneath tile or wall panels. These products are installed over approved subfloors and substrates, then detailed at corners, transitions, and pipe penetrations to reduce pathways for water intrusion. Rather than relying solely on surface sealers or caulking, the system manages water penetration at the structural level where leaks commonly start.

A properly waterproofed laundry floor also provides a stable, sealed surface that resists moisture under heavy appliances and regular traffic. When walls are protected with waterproof panels or membranes, splashes and condensation are kept off surrounding surfaces, making the space easier to keep clean and reducing long-term maintenance needs.

Why Laundry Waterproofing Improves Everyday Use

Helps protect laundry floors from water exposure
Waterproof membranes and substrates block water from reaching subfloors and structural materials beneath finishes.
Seals areas around washers and utility sinks
Proper waterproofing closes off seams, transitions, and weak points that water can exploit.
Shields walls with durable waterproof panels
Panels and membranes help prevent splashes and condensation from damaging wall surfaces or framing.
Reduces mold and mildew risk
By limiting moisture penetration behind finished surfaces, the system helps reduce conditions where mold and mildew can develop.
Supports a more reliable laundry room layout
A waterproof floor surface combined with protected walls reduces the chance of hidden water damage and costly repairs over time.

Laundry waterproofing isn’t just preventative, it helps transform your laundry room into a space that stands up to moisture, stays easier to maintain, and protects your home’s structure from hidden water issues.

How do I waterproof my laundry room floor?

Installing a waterproof laundry room floor membrane and compatible substrate creates a sealed surface that protects subfloors from water and supports heavy appliances.

Are waterproof wall panels good for laundry rooms?

Yes. Waterproof wall panels and membranes help protect walls from splashes and condensation and make surrounding surfaces easier to clean and maintain.
