Frequently Asked Questions

If you don't see the answer you're looking for, feel free to reach out to our team at any time.

  • How does a hot mop waterproofing system actually work?

    Our hot mop system works by creating an impenetrable, multi-layered waterproof barrier. We begin by applying a precise pre-slope of a quarter-inch per foot, ensuring water flows directly to the drain. Next, we apply three alternating layers of high-quality liquified tar heated to 500 degrees, roofing-grade 15-weight perforated felt, and fiberglass corner reinforcement. The tiny holes in the felt allow the hot liquid tar to pass through, bonding the layers into one solid, watertight membrane. Water penetrating your porous tile and grout safely reaches this sloped barrier, exiting through the weep holes and avoiding costly subfloor rot.

  • Why is hot mopping better than other shower waterproofing methods?

    Hot mopping is the most reliable waterproofing method available, with a proven track record spanning over 64 years. Unlike synthetic liners or paint-on membranes, which can easily puncture, tear, or degrade over time, our hot mop application creates a thick, seamless, and incredibly durable barrier. It bonds directly to the structure, meaning there are no seams or weak points that can fail. This traditional method stands up to shifting foundations and heavy daily use. It provides long-lasting peace of mind, saving you from the incredibly expensive repairs associated with mold, bacteria, and wood rot.

  • Can hot mop be used for waterproofing areas other than showers?

    Absolutely! While hot mopping is famous for shower pans, its incredible durability makes it perfect for many other waterproofing applications. Over the last half-century, we have expanded our services to protect a wide variety of surfaces. We expertly apply our hot mop membrane to decks, balconies, Roman tubs, planters, and foundations. Any area prone to water exposure can benefit from this seamless, multi-layer barrier. Whether you are building an outdoor living space or securing a planter box, our hot mop process delivers superior, long-lasting protection against leaks and structural water damage.

  • What happens if a shower pan is not properly sloped before waterproofing?

    Without a proper pre-slope, water that penetrates your porous tile grout and mortar will have nowhere to go. Instead of flowing toward the drain, the water will pool directly on your flat shower subfloor. Over time, standing water creates a breeding ground for harmful mold, mildew, and bacteria. Eventually, this trapped moisture will rot the wood framing and subfloor, leading to catastrophic structural damage and extremely expensive repairs. We prevent this by always installing a precise quarter-inch-per-foot pre-slope before applying our hot mop, ensuring water always flows safely down the drain.
