Shower Pans
Hot mopping and waterproofing
Hot mopping is a traditional and highly durable method of waterproofing a shower pan. This process involves layering hot liquid asphalt (tar) and roofing felt over a sloped mortar bed, creating a seamless, impermeable barrier that is essential for preventing leaks, water damage, mold, and rot beneath your tile. This ensures the longevity and structural integrity of your shower. See Gallery →
Project benefits
Water inevitably seeps past tile grout, making a fail-safe membrane necessary to direct moisture to the drain. This protects the subfloor and framing from the costly effects of moisture intrusion.

Roman Tubs
Hot mopping and waterproofing
Hot mopping a Roman tub is a crucial step that involves layering hot asphalt and felt paper to create a robust, seamless, waterproof membrane beneath the tile. This process effectively prevents leaks, mold, and potentially costly structural damage to your subfloors and walls, ensuring your bathroom remains both beautiful and functional for years to come.
Project benefits
By creating a waterproof “pan,” hot mopping guarantees that water stays contained in the tub area, protecting your home from water damage. It’s an essential component of any high-quality bathroom remodel that you can’t afford to overlook.
Balconies
Hot mopping and waterproofing
Hot mopping is a highly effective and trusted waterproofing method for balconies. By applying layers of hot liquid asphalt and felt paper, this technique creates a seamless and impenetrable barrier against water. This powerful protection prevents leaks, rot, mold, and structural damage, safeguarding the integrity of your space beneath the flooring. Given that balconies face constant exposure to moisture, investing in proper waterproofing is essential to prevent costly damage and eliminate health risks associated with mold. See Gallery →

Decks
Hot mopping and waterproofing
Hot mopping is a highly effective and time-tested waterproofing method specifically designed for flat or low-slope decks.

With hot mopping, you ensure the longevity and durability of your deck, providing peace of mind and investment protection for years to come.
Specialty Projects
We specialize in creating elegant indoor and outdoor fountains to enhance any space, along with beautifully crafted planter boxes that add sophistication and greenery to your environment.

Fountains
Hot mopping fountains is essential because porous materials like concrete and terracotta absorb water, leading to cracks and damage. A proper hot-mopped system protects the base and surrounding area from moisture intrusion.
Interior Fountains
Crucial for indoor fountains, especially those in bathrooms or entryways, to protect flooring and subfloors from constant moisture.
Exterior Fountains
Vital for outdoor fountains (concrete, stone) to prevent water absorption, which can lead to cracking from temperature changes (freeze-thaw cycles) and protect the surrounding hardscaping.

Planter Boxes
Hot mopping is vital for planter boxes to prevent structural damage to surrounding areas, deter mold, and protect materials like wood and concrete, while keeping plants healthy by avoiding waterlogging and root rot.
Waterproofing is necessary because planters are constantly wet, and without it, water seeps out, causing rot, mildew, and structural issues, while also harming plants.
