St. Louis is a brick city with concrete details, and the concrete is what wears out. Two flats and four families across Tower Grove, Bevo and Dutchtown have a short public walk, a flight of steps to the door and a strip of drive that runs down the side of the lot to a garage off the alley. All of it is narrow, all of it is old, and all of it takes salt every winter from the street, the sidewalk and whatever the neighbor throws down.

The failure is rarely structural. The slabs were poured thick and they are still carrying a car. What has gone is the wearing face, flaked away by water freezing in the top of the concrete and by chloride working into it year after year. Owners in Shaw or the Central West End get quoted a tear out, look at the cost of getting a breaker and a dumpster onto a lot with no side access, and put the job off another season.

Resin bound gives you a third answer. Natural stone aggregate pre mixed with a clear resin binder is hand troweled straight over sound concrete, so nothing gets broken out or hauled away. The finished surface is fully permeable, seamless and slip resistant when wet, and it wraps steps, walks and an alley apron as one piece. Resin Rock supplies the binder, the aggregate and the training behind the installers who lay it here.

Underneath a lot of this city is the heavy black clay everybody calls gumbo. It holds water like a sponge through a wet spring, then bakes hard and pulls back in August. Concrete poured on it lifts, drops and goes out of plane with whatever is next to it. That is where the classic St. Louis complaints come from. A public walk with a two inch step between flags. Front steps that have pulled away from the stoop. A patio in Webster Groves that has tilted back toward the house and now sends water at the foundation.

Salt does the rest, and this metro uses a lot of it. City, county and MoDOT crews treat ahead of storms, and it arrives at your property on tires, on shoes and off the sidewalk. Chloride keeps concrete wet longer, so the surface gets more freeze cycles rather than fewer, and where mesh or rebar sits shallow the steel rusts and pops the face off. Alley aprons take the worst of it, because that is where the plow pile, the trash truck and the melting slush off every parked car all end up in the same ten feet.

Resin bound is natural stone aggregate pre-mixed with a clear, UV stable resin binder and hand troweled straight over your prepared concrete. It cures into one seamless, fully permeable sheet with no loose stone and no joints for weeds to find.

Because the stone is blended into the resin before it ever touches the ground, every piece is locked in place. That is the difference between resin bound and resin bonded, which scatters loose stone onto wet resin and gives you a rough, non permeable finish that still needs separate drainage designed in.

For most St. Louis homeowners the appeal is simple. You keep the slab you already paid for, you lose the cracks, stains and trip edges, and you end up with a surface that drains through itself instead of pushing water at your foundation.

You are choosing stone, not paint, so the finish has depth to it rather than a flat printed color. Resin Rock stocks more than 30 blends of quartz, granite, marble and basalt, all screened for consistent size and shape so batches match. That consistency is what stops a driveway looking patchy where one day's work meets the next.

Think about how the surface gets used before you think about how it looks. Barefoot areas want light quartz or marble. Parking areas want something mid to dark that forgives a tire mark. Anything next to the house usually looks best picking up a tone already in the brick, render or stone.

For feature work, Glow Rock from Glow Surfaces charges in daylight and glows softly after dark. It works as a path edge, a pool surround border or a driveway inlay rather than a whole surface.

Fifteen years and up is a realistic life on a properly installed surface, and looking after it is mostly a matter of keeping the pores open. Leaves, grass clippings and dust are what clog a permeable surface, so a blower or a stiff yard brush every few weeks does most of the work. A wash down once or twice a year handles the rest.

When you jet wash, use a wide fan tip and keep it a foot back. A turbo nozzle held close will strip resin off the top of the stone, and so will a wire brush or a strong solvent. Warm water and a soft brush deal with almost every spill. Nothing grows up through the surface, but seed can root in debris left sitting on it.

If a section ever does get damaged, resin bound is repairable. An approved installer can cut out and relay a patch in the same blend rather than replacing the whole surface.
