Michigan is unusual in one useful way. Where most of the country paved its suburbs in asphalt, Michigan poured concrete, and a huge share of the driveways in Troy, Royal Oak, Grand Rapids and the Detroit suburbs are slabs rather than blacktop. That is good news if the surface has gone bad, because a sound concrete slab is exactly what resin bound is designed to be laid over. You are not starting from scratch. You are reusing what is already there.

What kills those slabs is not age. It is chloride and water. Michigan road crews salt and brine hard from November through March, every tire tracks it up the drive, and the state runs a freeze and thaw cycle that swings back and forth for months. Add Great Lakes moisture and lake effect snow across the west side, and the top inch of the concrete takes a beating no mix design can shrug off forever.

The usual quote is tear out and re-pour. That means demolition, disposal, forms, a pour and then a cure period, inside a season that only runs from about late April to October. Resin bound resurfacing keeps the slab and adds a permeable, seamless surface on top. Resin Rock supplies the binder, the aggregate and the training behind the approved installers who lay it, with Michigan served through our Illinois distribution point.

Start with salt, because Michigan gets more of it than most states. Trucks pre wet with brine before a storm and salt through it, and the mix does not stay on the road. It comes home on the tires, drips off in the garage and gets shoveled off the walk onto the lawn edge. Chloride works into porous concrete. Where mesh or rebar sits shallow, the steel corrodes, expands and pushes the face off the slab. That is the pitting and flaking you see across the apron and the first ten feet of a Michigan driveway.

Then the freeze and thaw. The temperature here crosses freezing over and over rather than dropping once and staying down, so water taken into the surface expands, relaxes and expands again. Each cycle takes a little more off the top. The result is scaling, the thin sandy flaking that turns a smooth drive into something that sheds grit every time you sweep it. West Michigan gets an extra dose, because lake effect snow means the surface is wet more often than it is dry.

Underneath, the ground moves twice a year. Frost drives deep into southeast Michigan clay over the winter and lifts everything above it. In March and April it lets go, and that is the season of potholes, lipped sidewalk flags and driveway panels that have come out of level with each other. On the sandy soils along the lakeshore the movement is different but no kinder, because water moves through fast and washes fines out from under an edge. Patching in May is treating a symptom that returns in March.

Resin bound is a mixed-on-site surface. Aggregate and a two part UV stable resin go into a forced action mixer at an exact ratio, and the resulting blend is troweled over your existing concrete at depth. It cures into a single seamless, porous sheet.

People confuse it with resin bonded, and the two behave nothing alike. Bonded work scatters dry stone onto a resin coat, so the surface is textured, sheds loose grit and holds water on top. Bound work carries the resin all the way around every stone, which is what makes it flat, fixed and free draining.

The practical result in Michigan is that you keep your slab, lose the cracked and stained surface on top of it, and gain something that handles rain by absorbing it rather than pushing it toward your foundation.

Two questions decide whether a surface survives here. Can water get out of it, and what happens when chloride lands on it. Resin bound handles the first one by being permeable. Rain and snow melt drain through the stone matrix into the sub base instead of sitting on the surface or soaking into a concrete face that then freezes. Where the sub base is porous and correctly compacted the whole build up works as permeable paving. In a state where the surface is wet for a large part of the year, that changes the failure clock completely.

On salt, no exterior surface enjoys de-icing chemicals and anybody who says otherwise is selling. What resin bound does is wrap every stone and the slab below in a cured resin skin, so chloride is not soaking directly into bare concrete. The rest is care. Use a poly or plastic shovel rather than a steel edged one. If you plow, fit a rubber or poly cutting edge, run it on skids and set it slightly high. Use de-icer sparingly rather than by the scoop. Given Michigan winters, agreeing this with your plow contractor before the first storm matters more here than almost anywhere.

Resin Rock carries more than 30 aggregate blends drawn from quarries around the world, screened so bag matches bag. Quartz gives you clean, bright, consistent color. Granite reads more natural and hides dust well. Marble runs lighter and cooler underfoot, which people like around pools. Basalt goes dark and modern.

Lighter blends stay noticeably cooler in direct sun, which is worth thinking about for a pool deck you walk barefoot. Darker blends hide tire marks better on a driveway. Most homeowners land on a mid tone blend that does both jobs reasonably well.

For feature work, Glow Rock from Glow Surfaces charges in daylight and glows softly after dark. It is used as a pathway 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 using the same blend rather than replacing the whole surface.
