Question 1

Should I repair my driveway or just replace it?

Accepted Answer

Repair if the slab is structurally sound and the damage is isolated. That's most cases. Replace if much of the slab is broken, if there's deep subgrade failure that won't hold under a new slab, or if the original slab was poured too thin for the use it's getting. We'll tell you honestly when replacement is the better long-term spend, even though it's a bigger job.

Question 2

What is polyjacking and how is it different from mudjacking?

Accepted Answer

Both lift sunken slabs by injecting material underneath them. Mudjacking uses a cement-and-soil slurry pumped through larger holes. It's cheaper but heavier, which can re-load weak subgrade, and the holes are visible. Polyjacking uses high-density polyurethane foam injected through small ports. It's lighter, sets quickly, the holes are nearly invisible after patching, and the foam doesn't wash out from irrigation or rain. We use polyjacking for most residential lifts.

Question 3

How long do crack repairs actually last?

Accepted Answer

Polyurethane crack injection on a properly routed crack is long-lasting on a stable slab. Epoxy crack injection is structural, so it bonds the slab and holds as long as the cause of the original crack (settlement, root pressure) was addressed. The repairs that fail early are the ones where someone smeared caulk over an unrouted crack without cleaning it first. Those don't hold up.

Question 4

How soon can I drive on it?

Accepted Answer

Crack injection allows foot traffic the same day and vehicles by evening. Polyjacking takes vehicle traffic the same day. Saw-cut patches take a day for foot traffic and a couple more before driving on the patched area. Sealer cures the same day and is rain-safe overnight. We give you specific times based on what we did and the weather.

Question 5

Can you match the color and texture of my existing concrete?

Accepted Answer

Close, not perfect. Older concrete has oxidized, weathered, and changed color from the original era. New patch concrete starts out lighter and darkens as it cures and weathers. We match texture (broom finish direction, stamp pattern) carefully, and we use integral pigment and surface tinting to get the patch as close as possible. Sealing the whole driveway after the repair helps even out the visual difference.

Question 6

Do you handle stamped or decorative concrete repairs?

Accepted Answer

Yes, and they require more skill than plain gray concrete. We have the stamp mats and color hardeners to recreate common patterns (slate, ashlar, cobblestone, Roman seamless). Custom stamps may need to be sourced. Decorative repairs cost more per square foot than plain concrete repairs because of the matching work involved, but they save the entire decorative slab from replacement.

Question 7

Do I need a city permit to repair my driveway?

Accepted Answer

For in-kind repair on the private portion of the driveway, no permit is needed in most OC cities. Anything that touches the apron between the sidewalk and the curb is a different story. That portion is in the public right-of-way and requires an encroachment permit from the city public works department. We pull the permit when needed and handle the inspection scheduling. Cities like Newport Beach, Irvine, and Mission Viejo each have their own permit form and review timeline.

Question 8

How often should I sealcoat or seal my driveway?

Accepted Answer

Concrete driveways do well with a penetrating siloxane or silane sealer on a regular service interval. The sealer blocks moisture intrusion, the main driver of cracking and spalling, and slows oxidation from UV. Asphalt driveways need a different product, a coal-tar or asphalt-emulsion sealcoat, on a shorter interval. Sealing immediately after a repair locks in the patch and evens out the visual difference between new and old concrete.

Question 9

What causes the spalling and surface flaking on my driveway?

Accepted Answer

A few usual causes in OC. First, rebar corrosion, especially close to the coast where chloride from salt air penetrates the slab and rusts the steel from the inside out. The expansion pops the surface off. Second, weak surface laitance from a slab that was over-troweled or had water added at the pour. Third, alkali-silica reaction in slabs poured with reactive aggregate, which we see occasionally in older pours. The fix depends on the cause. Coastal spalling usually needs a partial replacement plus a chloride-blocking sealer. Surface laitance can be ground off and resurfaced.

Question 10

Will polyjacking work if my soil is expansive clay?

Accepted Answer

Yes, and it's actually a better choice than mudjacking on clay subgrades. Expansive clay (common in Yorba Linda, Anaheim Hills, and the Mission Viejo foothills) swells when wet and shrinks when dry, which is why slabs over clay heave and settle seasonally. The polyurethane foam is much lighter than a cement slurry, so it doesn't re-load the weak clay underneath. The foam also fills voids without absorbing water, so it stays stable through seasonal moisture swings.
