Clay movement, tree roots and irrigation water are behind most damaged concrete in San Jose. We find the cause first, then seal, grind, patch, resurface or replace the section. Text a photo and we can often say which it will be.
The first question with damaged concrete is why it failed, because the fix depends on the cause. In San Jose the usual causes are clay movement, tree roots, water from irrigation or a downspout, and old slabs that were poured thin with no steel. A hairline crack in a slab that is still flat is a small matter. A slab that has tilted, dropped or broken into rocking pieces has lost its support.
We seal and rout cracks, patch broken edges and corners, grind raised lips, resurface worn tops, and cut out and repour single sections. A lifted or sunken section of driveway or walk can often be replaced on its own without redoing the whole thing. We will tell you plainly when a repair is money wasted, for example a thin overlay on a slab that is still moving.
New concrete next to old never matches in colour at first, and we say so up front. It weathers closer over a year or two but stays visible. If appearance matters, replacing to the next joint line or resurfacing the whole area gives a more even look. Send photos and rough sizes and we can usually tell you which direction makes sense before we visit.
Concrete repair in San Jose: common questions
Can you fix one section of my driveway without replacing all of it?
Usually, yes. We saw-cut at the nearest joints, remove the bad section, rebuild the base and pour it again. The new section will look newer than the rest for a while.
Is a crack in my garage floor a sign of earthquake damage?
Most garage floor cracks are from shrinkage or soil movement, not from an earthquake. Cracks that are wide, offset in height, or that continue up the foundation wall deserve a look from a structural engineer.
Will a patch last on San Jose clay?
A patch lasts when the slab under it is stable. If the soil is still lifting and dropping that section each year, the patch cracks again. We check for movement before recommending one.
