Highlands Ranch Concrete Curbing

You can diagnose most yards from the street. Plastic edging that has popped up out of the bed and now waves along like a black snake. A steel strip with a rusted lip standing an inch proud, waiting on somebody's bare foot. Rock spilling out onto the lawn where a border used to be, and a mow line that has crept a foot and a half into the planting since April.

Every one of those is the same failure in a different costume. The edging had no weight to it, it never went deep enough to matter, and Colorado ground pushed it aside. Poured curbing ends the argument: nothing to unstake, nothing to lift. It's a continuous little beam of concrete with a footing built in, and mowers, freeze cycles, and a ton of river rock all lose to it.

What you're seeing from the street

Extruded or formed, and which profile to run

Most residential edging goes in with a curb machine. We feed a stiff, low-slump mix through it and it extrudes a continuous curb right on the bed line, which is why the curves come out smooth instead of faceted the way segmented products do. It's fast, it wastes almost nothing, and radius work is where it separates from the alternatives; a machine curb follows a sweeping arc around an island bed with no visible seam.

Formed curb is the other half of what we do, and it earns its keep where the machine can't help: taller retaining lips, curbs that step down a slope in even increments, straight lines along a walk. Slower, more labor, better result in those spots.

Profile is a real decision, not a catalog page. The slant or rolled top is what we push for anything bordering turf, because the mower wheel rides up on it and you stop hand-trimming the whole yard every week. A square profile looks sharper against modern architecture and holds deeper rock beds, at the cost of taking every shovel and mower hit on the corner. Eastridge yards are usually the first type, redoing beds that have fought sunken edging for decades. In BackCountry the curbing more often goes in with the plantings, and taller square profiles show up more there.

How a curbing install runs

• Bed line laid out with a hose and walked from the porch and the street before anything is cut
• Sod cut, trench dug to depth, and the spoil hauled off instead of spread in your beds
• Trench bottom hand-tamped so the curb bears on firm ground the whole way
• Sprinkler lines and heads located, with sleeves set wherever a line has to cross
• Machine run for the main pull, then radii and terminations hand-tooled
• Control joints tooled at a regular spacing while the concrete is still green
• Integral color and a pattern roller if you picked them, then a sealer coat

Sprinklers, freeze cycles, and the right month to install

Curbing lives in the wettest microclimate on your property, and that's its main enemy. Irrigation runs three or four times a week straight onto a small section of concrete, so it goes into winter saturated, and a saturated section cycling through freezing and thawing is working against itself every night. Two things counter that: air entrainment in the mix, which we don't skip, and a sealer on colored curb renewed every few years. Adjusting heads so they water plants instead of concrete costs nothing and helps more than either.

The other damage source is the shovel and the plow blade, specifically where curbing runs along a driveway or a walk. Snow gets pushed toward the bed, the blade catches the curb, and you chip a corner. It's another argument for a rolled top, which deflects a blade instead of stopping it.

Installation season runs from the ground thawing in spring through to about the end of October. Curbing is quick, so it drops into a schedule without much lead time even during the busy months. Fall is quietly the best window: beds are getting cut back anyway, digging is easier in cool weather, and the curb cures for months before it faces a full irrigation season. Winter is the one time we'll tell you to wait. The machine needs unfrozen ground, and a thin section is far harder to protect through a cold night than a slab.
