Portland, Oregon

Foundation contractors across Washington County, Clackamas County and the valley floor spend their winters on the same problem: clay soil that expands when it is wet and contracts when it dries. That movement transfers into the concrete above it, which is why so many Portland homes develop cracks and uneven floors that were not there when the house was built.

Any coating bonded to that slab has to accommodate the same movement, and this is where rigid systems come apart. Standard epoxy has very little give. When the slab shifts, the coating cannot follow, so it crazes, then lifts at the crack edges, and once moisture reaches that edge it spreads. Ours has 120% elongation, so it stretches with the slab rather than fracturing across it.

The second problem arrives from below. Heavy rainfall keeps the water table high, and that produces real hydrostatic pressure against foundations and slabs. Moisture moves upward through the concrete as vapor, and when it meets a coating that sealed the surface without properly bonding to it, the pressure lifts it away. That is the bubbling and peeling most Portland homeowners have either had or seen. Ours bonds at 100% adhesion with 0.3% water absorption, so it seals the slab rather than trapping moisture beneath a film, and we assess slab conditions at the estimate rather than afterwards.

Outside, the same damp brings moss and mildew. Bare concrete is porous, and every pore holds the moisture and grit they need to establish. A patio or walkway that goes green each winter is not dirty, it is absorbent. Our surface is seamless and non-porous, so there is nothing to take hold in, and it is UV stable so it holds its color through the summer months rather than chalking.

Then there is hot tire pickup, which catches people out even in a mild climate because the heat comes from the tire rather than the air. A coating that softens under a warm tire grips the rubber and tears away when you reverse out, leaving a crescent under each wheel. Ours is hot tire resistant and rated for continuous service to 200°F.

Installation takes a day. Most floors need only a broom-sweep prep, though some require mild grinding or sanding, and the floor is ready for full use in 24 hours. The coating applies from -20°F to 120°F, so the work is not restricted to a narrow summer window, and the basecoat is zero-VOC and odor-free.

We work across the Portland metro on garage floors, basements, and patios, walkways, and steps, finished in any of 250+ color and flake combinations. Residential installations carry our residential limited lifetime warranty.
