TIRED OF YOUR OLD, COLD, UNFINISHED BASEMENT FLOOR?
From storage basements to finished living spaces, we install durable epoxy, flake, quartz, and metallic coatings built to handle below-grade moisture and give your basement a floor that actually feels like part of the home.


WHAT WE OFFER
TYPES OF BASEMENT FLOOR COATINGS
Every basement is used differently, storage, a home gym, a rec room, which is why we offer multiple coating systems, each customizable for moisture resistance, color, and finish. Not sure which one's right for you? We'll walk you through the options and recommend the best fit.

EPOXY FLAKE
A durable, decorative coating broadcast with color chips for texture and depth. A popular choice for basements that see regular foot traffic, storage use, or double as a workout or hobby space.

METALLIC EPOXY
A show-stopping, 3D marbled finish that turns a basement into a real living space rather than an afterthought. A strong fit for finished basements, home theaters, or entertaining areas where the floor is meant to be seen.

QUARTZ
A blend of colored quartz granules broadcast into epoxy for a rich, natural texture. Slip-resistant and highly durable, a solid choice for basement gyms, laundry areas, or spaces near a bathroom or utility sink.

SOLID COLOR
A clean, single-color finish for a smooth, uniform look. The most straightforward and budget-friendly system, ideal for basements used mainly for storage or utility purposes.
HOW IT WORKS
DIAMONDGUARD™️
FLAKE FLOOR SYSTEM
As a family-run team, we don’t cut corners on prep or materials, because a basement floor installed right stays low-maintenance for the long haul. No waxing, no resealing, just a quick sweep or mop when it needs it.
Decorative flakes broadcast into the wet basecoat for color, texture, and visual depth, helping the space feel finished rather than like a utility room.
The tinted coating applied directly over the prepared concrete, bonding to the slab and anchoring the flake layer.
The texture created during grinding or prep, including moisture testing specific to below-grade slabs, ensuring the coating bonds properly and doesn’t trap vapor underneath.





HIGH QUALITY,
LOW MAINTENANCE
As a family-run team, we don't cut corners on prep or materials, because a patio coating built for Oregon's weather stays low-maintenance for the long haul. No resealing, no repainting, just an occasional hose-off or sweep.
