Concrete Crack Repair
Width matters less than movement. If the edges have shifted vertically, or the crack runs corner to corner, the ground moved and a surface fix will crack again in the same line. We say which one you have.
Talk to us about the job
How the job runs
Come and see it
We look at the actual site before talking money. What the ground does, where water runs, how the truck gets in, and what the old concrete is telling us.
Give you the real scope
A straight answer about what is needed. Sometimes that is less work than you were braced for.
Build from the bottom
Grade, material, lifts, compaction. The slab is the visible half of a job that is mostly earthwork.
Form it and pour it
Forms braced properly, steel at the right height with real cover, and a pour that gets consolidated rather than just placed.
What this job actually needs
Movement matters more than width
A hairline crack that has not moved is a different problem from a quarter inch crack with vertical displacement. We look at whether the edges have shifted, whether it runs corner to corner, whether it lines up with a control joint, and whether it opens and closes seasonally. Those answers decide the repair.
Static cracks
A crack in a slab that is sitting flat on a stable base gets chased out to sound concrete, cleaned, and filled with a material chosen for whether it needs to flex. Done properly it stops being a water path into the base, which is what actually kills slabs.
Moving cracks
If the ground is still moving, a surface repair will crack again in the same line, usually within a year. That is not a failed repair, it is the wrong repair. Where we find movement we will tell you what it would take to fix the cause, even when that is a bigger conversation.
Why filling every crack is not the goal
Control joints are supposed to open. Sealing them rigid transfers the movement somewhere else and creates a crack you did not have. Part of the work is knowing which lines to leave alone.
What decides whether it lasts
Concrete is judged on the surface and it fails from underneath. The base, the steel, the joints and the cure are the whole job. A slab that was poured on bad ground will tell you so, usually in the third or fourth year.
Why fourth generation matters here
32 years on the tools means most of these problems have already been seen once. Reading a slab before quoting it is the part you cannot learn from a book, and it is the difference between a repair that holds and one that comes back.
What Southern California ground does to concrete crack repair
Summer pours
Triple digit afternoons change how concrete behaves. It stiffens before it can be finished properly, the surface skins over while the body underneath is still soft, and water leaves the slab faster than the cement can use it. Valley pours start early, the mix gets adjusted for the heat, and curing is treated as an active step instead of something that happens on its own.
Irrigation against the slab
Almost every valley property waters something, and sprinklers running along a slab edge keep the base saturated year round. In expansive soil that is a slow way to undermine your own driveway. Where the water lands is worth looking at before blaming the concrete.
Older flatwork around here
A lot of valley concrete was poured thin, with light reinforcement, on a base that was never properly compacted. When it fails it is usually reporting on the ground rather than on the mix, and that is the difference between a repair that holds and one that comes back in a year.
Drainage on a flat lot
Valley lots are often close to level, which makes slope hard to find and easy to get wrong. Low points, cross-fall and where water actually leaves the property get worked out before the pour, because once the concrete is down the drainage is permanent.
How concrete fails, and why
Cracking that follows no joint
When a slab cracks in a line nobody cut, it is almost always telling you about restraint or about the ground. A slab poured tight against a footing cannot shrink, so it tears instead. A slab over a soft spot bends until it breaks. Neither is a concrete defect.
Spalling and surface loss
Flaking down to the aggregate is the top layer letting go. The usual causes are water working in and out, chloride from de-icing or fertiliser, and a surface that got sealed too early during finishing so bleed water was trapped under it.
Panels at different heights
A lip at a joint means one side moved. Sometimes that is a root, sometimes erosion under the slab, sometimes a void left by poor compaction. Grinding the lip removes the trip hazard and does nothing about the cause.
Standing water
Water that sits is a grading problem that got set in concrete. It accelerates every other failure mode, because water is what carries chloride in and what freezes in the pores.
How a job runs
Before we start
You get told what is being built, how long the concrete is unusable, and where the truck and the crew will be. Access gets sorted before the day, not on it.
The day of the pour
Concrete arrives on a schedule and does not wait. The crew works to the material, which means the pour is not a good day to renegotiate the scope.
Once the slab is down, the drainage is permanent.On grading
After the pour
Foot traffic usually after a day or so, vehicles longer. You get the real numbers for your slab, because thickness and weather both change them.
The first month
Concrete keeps gaining strength for weeks. Hairline shrinkage cracking in that window is normal and is not a failure. Anything that worries you, call and we will look.

Straight answers
Can a sunken slab be lifted?
Often, if the slab is still in one piece and the problem is a void underneath. If it has broken up, lifting the pieces just gives you level pieces.
Is my crack serious?
Width tells you less than movement. If the edges have shifted vertically, or it runs corner to corner, the ground moved and a surface fix will crack again in the same line. We look before we quote.
Repair or replace?
If the slab is sitting flat and the base is stable, it is a repair. If it has moved, the concrete is reporting on the soil and replacing without fixing that buys the same failure again.
Can you resurface instead of replacing?
If the damage is only in the top layer and the slab underneath is sound, yes. If the slab is moving, an overlay hides the problem for a season and then telegraphs through.
Why is my concrete flaking?
That is spalling, and it is usually water, salt, or a surface that was closed too early during finishing. Repair means getting off everything loose, down to sound concrete, and bonding new material properly.
