Why Crazy Curbs

We don't skip steps. We add them.

The difference is in the mix, the finish, and the details other crews rush past. Here's what goes into every foot of curb we pour.

Precision zero-slump mix

Cleanest washed plaster sand and locally-processed Riverside Portland Cement, batched to the exact same ratio every time — the only way to get a curb that lasts a lifetime.

No forms, same-day finish

Extruded straight onto grade at 1800 psi — no footings, no forms, no second-day teardown. Half the price of formed curb, none of the wait.

Custom corners & hand packs

90° squares, sweeping curves, tight planters, tree circles — if you can draw it, we can hand-pack it. Unlimited design, no "we can't do that."

Integrated oxide color

Powdered oxides mixed through the whole batch — not painted on. Scratch it or chip it and the color's still there. Match your trim, your hardscape, your vibe.

Curb Shapes & Specs

Four profiles. One perfect fit.

Every yard is different. Pick the shape that matches your edge — all available in a wider 6″ profile for extra durability.

Mower Style

5″ wide · 4″ back / 2″ front

Our most popular. The low side lets a mower tire ride the edge; the high side keeps mulch and rock out of the grass. "Crown molding for your yard."

Block Curb

5″ wide · 4″ tall

Traditional squared profile. Installs on top of or flush with grade — ideal for paver borders, artificial turf, putting greens, tree wells and DG paths.

Most versatile

Wide utility and commercial concrete curbs

Utility Curb

6″×4″ or 6″×6″

Heavy-duty and rebar-ready for parks, schools and HOA common areas. Fill with DG or gravel to build economical driveways and walk paths.

Commercial grade

Angled Curb

5″ wide · 4″ back / 2″ front

Built for stamp-and-color systems and a subtle, contemporary look. Standard broom-grey finish available too. Also offered in a 6″ width.

Colors & Stamps

Make it unmistakably yours.

Random rock, slate, river rock and brick stamps — paired with any color on the chart — turn a plain border into the best-looking line on the block.

Random RockOrganic, natural texture

Slate StoneLayered, contemporary

River RockRounded, coastal look

BrickClassic, timeless

Crazy Curbs integrated oxide color chart

Integrated powder-oxide colors, mixed through the whole batch. Because of local water minerals and natural material variation, finished color may appear lighter than shown.

The Machine Advantage

Formed curb vs. machined curb.

Old-school formed curbing is slow, needs footings, and costs double. Machine-extruded curbing is faster, tougher, and finished the same day. It's not close.

Formed The old way

Forming is slow and labor-heavy
Tends to "fish belly" between stakes
Requires a footing
Second-day return to strip forms
Roughly double the price

Machined The Crazy Curbs way

500–600 linear feet completed per day
Consistent, uniform, very durable at 1800 psi
No footing, no forms — same-day finish
Glue or dowel into existing concrete & asphalt
Enveloping over rebar for even higher psi

Inspect & cut the path

We walk the area, then carve a shovel-wide path for the machine to follow — cutting high spots, filling the lows.

Shower the grade

A light shower of water reveals any low areas and moistens the soil. An inch or two of moisture — not mud — is perfect.

Mix to zero slump

Precision batch of sand, cement and water — so dry it stands on its own. That's what makes it crack-resistant for life.

Extrude your shape

Concrete is wheelbarrowed to the machine and extruded in the profile you chose — clean, uniform, and continuous.

Hand-trowel the finish

Every foot is hand-troweled to a broom-textured, water-repelling finish that protects the concrete underneath.

Cut control joints

Control joints every ~4 feet (2 feet on tight turns) let the curb breathe, drain, and resist cracking through seasons.

In the Wild

Set up and showing off.

Gardens, mini-golf greens, turf borders, DG paths and property lines — a few of the curbs we've laid around the Inland Empire.

Prep Like a Pro

A little prep = a better-looking curb.

Our schedule stays busy, so having the area ready lets us do what we do best — install beautiful curbing. Here's how to set your job up for a flawless finish.

Clear the path

Remove grass, shrubs, branches, pet waste and furniture from the curb line. If you think it might be in the way — it will be.

DIY the trim-out

Have a gardener, teenager or neighbor cut back anything in our path and pull the grass. Rose bushes and thorny palms are our nemesis.

Moisten the soil

Run sprinklers the night before, or give it a gentle hose-down. An inch or two of moisture (not mud) in compacted soil is ideal.

Sprinklers off 24 hrs

Keep the timer off for at least 24 hours after install so the fresh curb can cure without getting soaked.

Keep everyone off

Pets, kids and water away from the curb for 24 hours. Unlike flatwork, wetting a new curb can actually damage the finish.

Mind the property line

Doing a dividing curb? Find the line, then come an inch onto your side. Neighbors get funny about an inch of concrete.

Beyond the Curb

We remodel, too.

Curbing is our craft — but the same crew remodels bathrooms, hangs crown molding, lays flooring and rebuilds backyards. One trusted team for the whole project, not a phone tree of subcontractors.
