Exposed Aggregate Concrete in Meridian, Idaho

Exposed aggregate concrete options for Meridian properties.

Seeded stone finish.

We pour a standard slab, then seed selected rock into the surface and press it in. The wash later reveals that stone. You pick size and color. This is how we get a look that the local ready-mix stockpile may not already have.

Washed native mix.

The stone is already in the truck. A surface retarder keeps the top paste from setting. We wash at the right time to leave the aggregate proud. Timing is tighter than a broom. Miss the window and you either bury the rock or wash it out.

Rock size and color.

Pea gravel is one look. Larger mixed stone is another. Light rock shows dirt. Dark rock shows dust. We make a sample board when the house is next to an old washed walk you want to echo.

Retarder timing.

Surface retarder is not a cure. It holds the top paste so we can wash it off. Sun, wind, and a dry August afternoon shrink that window. We plan the pour for the wash, not for the truck's convenience.

How we handle exposed aggregate concrete in Meridian.

1. We agree on seeded versus washed mix and on a sample if you need a match.
2. We form and place at the same thickness the slab use requires.
3. We apply retarder or seed stone, then protect the surface from footprints.
4. We wash to the agreed reveal, then cut joints and start cure.
5. We seal when the slab is ready and tell you how to shovel without prying stone.

Materials and methods.

Exposed work still needs air-entrained 4000 psi and a compacted base. The difference is the surface. Retarders, a hose, a broom for the wash, and sometimes a light pressure wash do the reveal. We do not cut so deep that reinforcement shows. Joints still follow panel rules. A washed field without saw cuts cracks through the pretty rock.

Exposed work still starts as air-entrained 4000 psi. Surface retarder, then a wash to the stone. ACI 302.1R joints underneath the pretty face. Isolation at the house. A grid of #3 bar is common on these patios. Mesh only if the quote says welded wire. Cure after the wash. Freeze-thaw will pop poorly seated stone. We do not seed a dry shake on a slab that already crusted. Timing is the method.

Edging is slower because the arris is stone, not paste. We tool what we can, then wash. Sealer brings the color up and helps lock fines. Skipping sealer in this sun leaves the surface thirsty.

Oil drips on a washed drive are harder to hide than on a gray broom. Say so if this is a daily-driver parking pad.

Older washed walks around the capital used a local blend that is hard to clone. We can get close with a seed. We cannot promise a match from a phone photo. A sample board on site is the honest path. If the adjacent walk is failing, replacing both at once looks better than a new island of stone next to a broken gray panel.

Winter shovel edges chip stone. A plastic shovel is kinder than a steel blade at the joint. Sealer helps lock fines but it is not armor. We say that up front so a popped rock in year three is not a surprise.

The wash is the finish. The slab is still thickness, base, and joints. We will not wash so deep that the stone sits loose. A sample board beats a phone photo when you want to echo an old walk.

What exposed aggregate concrete costs in Meridian.

HomeAdvisor lists exposed aggregate as a driveway finish at $8 to $12 per square foot, grouped with colored and polished options, while stamped sits at $12 to $18. Seeded custom rock and a match to an old walk add labor. Angi treats decorative overlays as a higher band than a standard broom. Local bids still move with demo and access. We quote that wash on the lot you have. We do not post a rock menu.

If this is a daily parking pad, say so. Oil marks show more on washed stone than on a gray broom.

Seeded rock and a washed native mix are two bids. Say which look you want.

Wash depth, cure, and laterals on exposed stone

I wash Meridian aggregate for grip and look, not as a shortcut around thickness. Freeze-thaw pops stone that was washed too deep or left without cure. The paste has to lock the rock. We hold the expose window tight and seal so winter ice does not pry the face. Irrigation laterals are the quiet killer on washed work. A head that throws on a fresh seed bed pulls cream and leaves a bald stripe. We map irrigation before the retarder goes down and we keep the clock off until the slab can take water without losing stone.

South Meridian fill still decides whether this finish belongs on the lot. A washed drive on rocking panels is a pretty failure. Structure first. When Ten Mile grade has dropped a corner, we rebuild base and pour new, then wash. Eagle custom lots ask for seeded blends that match an older Boise walk or a courtyard look. Those jobs get sample boards. Foothills grade changes how water sheets across the stone, so sealer choice and joint layout matter as much as rock color. Kuna farm approaches put truck tires and gravel on edges. I lean broom for daily truck pads and save exposed stone for house walks and sitting pads unless you want the wash and accept a thicker, sealed edge.

Hot wind shortens the wash window. Open lots south of town dry the retarder fast. We staff for that. Message (208) 741-7320 with a photo of the stone look you want and whether the pad is drive, walk, or patio. We quote seed versus native wash as different lines.
