Our Process
The hot mopping process is a reliable, old-school waterproofing method that creates a durable, impermeable seal by layering hot, liquid asphalt with felt paper. Installers heat asphalt in a kettle, then use a large mop to apply it to a prepared surface, embedding sheets of felt paper in the hot tar, repeating layers to build a waterproof membrane that directs water to drains and prevents leaks and damage.

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.
