Flake Floors
A decorative epoxy and polyaspartic floor with vinyl flakes broadcast throughout for a textured, slip-resistant finish that helps hide dirt and minor imperfections. Sealed with a durable topcoat for long-lasting protection against stains, chemicals, and wear.
Metallic Epoxy Floors
A premium, high-gloss epoxy system that creates a custom marbled look with depth and movement. A great fit for showpiece spaces that need visual impact along with stain resistance and everyday durability.
Quartz Floors
A heavy-duty, slip-resistant floor made by broadcasting colored quartz into a resin base for a clean, multi-tone finish. Ideal for garages, commercial spaces, and work areas that need extra traction and durability.

Grind & Seal
We mechanically grind the concrete to smooth the surface, remove imperfections, and prepare it for better performance. Then we apply a protective finish to reduce dust, improve stain resistance, and enhance the overall look of the floor.
