Concrete Repair in Portland, OR

Often yes, if the base underneath is still stable and the crack is not actively widening. We fill or rout-and-seal stable cracks, which is a fraction of the cost of replacement. If the base has failed or the slab is settling further, repair is only a short-term fix and we will tell you that upfront.

Settling usually means the soil or base material under the slab has eroded, compacted further, or was never adequately compacted to begin with. Oregon's heavy rainfall can wash out base material under a slab over years, which is why settling shows up more here than in drier regions. Slab jacking can releve a settled section without full replacement in many cases.

Some hairline cracking is normal as concrete cures and shrinks — that is what control joints are designed to manage. Cracks wider than about a quarter inch, cracks that are growing, or cracks paired with settling are signs of a real problem worth having assessed.

Repair is almost always less expensive than full replacement since you are not paying for demolition, base rework, and a new pour. The exact savings depend on the extent of the damage — we give you both the repair and replacement price during the estimate so you can compare.

Substantially, yes — lifting an existing panel avoids demolition, disposal, new base work, a new pour, and the cure time that goes with it, and the slab is usable again the same day or the next. That is the real argument for it. The argument against it is that lifting restores the elevation without addressing why the elevation was lost. If the void under the slab came from one-time settlement of fill that has now stabilised, lifting holds indefinitely. If it came from an active water path — a downspout discharging beside the slab, a leaking service line, or runoff scouring base material out from under the edge, which is the common version in Portland Metro — the slab will settle again, and the honest sequence is to fix the water first and lift second.

When the cause of the void has been dealt with, a properly lifted slab generally stays put for many years — the lift itself is not the part that tends to fail. It is the wrong choice in three situations: when the slab is cracked into multiple pieces rather than settled as a unit, because lifting fragments tends to move them relative to each other; when the concrete is badly deteriorated, since raising a slab that is already failing just relocates a bad slab; and when the underlying cause is still active. Anyone quoting a lift without asking where the water goes is not really diagnosing the problem.

It depends entirely on whether the problem is the surface or the slab. Resurfacing genuinely solves a worn, spalled, stained, or dated surface on a slab that is structurally sound and sitting level, and it costs far less than replacement. It does not solve structural cracking, settlement, or a slab pushing moisture up from below — and that last one is the usual reason an overlay lifts or delaminates a year or two later. In a wet climate the moisture question matters more than it does elsewhere, so it is worth confirming the substrate is sound and dry before committing to an overlay rather than after.
