Concrete poured on a poorly prepared base in East County cracks and settles within a few winters, because the ground here holds water and moves. Base depth, drainage, and reinforcement are what you are really buying. Describe the driveway, patio, or slab you need and licensed local crews will bid it.
A useful bid states excavation, compacted-base depth, slab thickness, reinforcement, drainage slope, control-joint layout, finish, curing, access, disposal, permit responsibility, and a unit price for unexpected subgrade work. Compare these details before price because wet soil preparation determines whether the finished slab stays level.
A residential driveway wants adequate slab thickness with a compacted crushed rock base beneath it, thicker where trucks or an RV park. Reinforcement, control joint spacing, and a clean subgrade matter more than the mix design most homeowners ask about. A bid that does not state slab thickness and base depth is not a bid you can compare.
Broom finish is the default for traction in a rainy climate, and it is the right call on any surface that will be wet half the year. Exposed aggregate and stamped patterns look better but need sealing on a schedule to keep from becoming slick with algae. Ask what maintenance the finish you want will actually demand here.
Hairline cracking is normal and cosmetic. Slabs that have heaved, settled unevenly, or spalled across the surface are usually past patching. Slab jacking can lift a settled section for less than a replacement when the concrete itself is sound. Have someone assess whether the underlying cause is drainage before pouring anything new.
Crumbling front steps, footings for a new deck or shop, and retaining walls on sloped lots are steady work in Gresham. Anything holding back soil needs drainage behind it and, past a certain height, engineering and a permit. Skipping the drain rock behind a wall is the most common reason walls lean within a few years.
Concrete work becomes expensive when excavation reveals soft soil, buried debris, or a thicker old slab than expected. A disciplined quote carries unit prices for additional rock, export, concrete, and reinforcement and explains who pays if access requires a pump. Those allowances let you compare risk in advance and keep the pour-day decision from becoming a rushed verbal change order.

Soils across much of East County drain slowly and stay saturated through the winter, which means a slab poured on unprepared ground sits on material that softens and shifts every year. A generous compacted rock base is not an upsell here, it is the reason your driveway is still flat in a decade.
Gresham gets more freezing rain and hard frost than the inner metro, and water that soaks into concrete and freezes causes surface spalling over time. Rock salt accelerates it badly. Sealing exterior slabs and using calcium magnesium acetate instead of salt keeps a driveway looking right much longer.
Driveway approaches that touch the public right of way typically require approval from City of Gresham Development Services, and structural elements like retaining walls and foundations need permits. Addresses outside the city go through Multnomah County. Confirm the contractor's Oregon CCB registration before scheduling a pour.
| Solution | Works best when | Main question |
|---|---|---|
| Crack repair | Cracks are stable without vertical displacement | Is water or soil movement still active? |
| Slab lifting | A sound slab has settled as a unit | Will drainage and voids be corrected? |
| Resurfacing | The slab is stable but cosmetically worn | Is the surface solid enough to bond? |
| Remove and replace | There is heaving, broad spalling, or failed base | What base and drainage details change this time? |
Flatwork commonly runs about $9 to $16 per square foot installed for a standard broom finish, with exposed aggregate and stamped work often $14 to $24. A typical two-car driveway replacement frequently lands between $8,000 and $16,000 including demolition and haul-off of the old slab. Removal of existing concrete, extra base depth on soft ground, and steep access all add. Pricing that comes in far below these ranges usually means a thinner slab or a skipped base.
They dug deeper than the other bidders wanted to and put in a real rock base. Four winters later the driveway has not moved a millimeter.
Slab jacked the settled section of our walkway instead of replacing it. Cost a fraction of what we expected and it is level again.
Their bid was the only one that spelled out the rock depth and where the control joints would land. They also pushed the pour a week rather than work on soft ground after all that rain.
Most of the year with the right precautions, but crews avoid pouring into hard frost or steady rain. Late spring through early fall gives the most predictable cure. Winter pours happen with blankets and admixtures, though scheduling gets weather-dependent.
Foot traffic is usually fine after a day or two. Passenger vehicles typically wait about a week, and heavier loads longer. Concrete keeps gaining strength for weeks afterward, so avoid parking anything heavy near the edges early on.
Fine hairline cracks are normal as concrete cures and are not a workmanship failure. What is not normal is a wide crack, a vertical offset between sections, or cracking that ignores the control joints. Ask what the contractor's warranty covers before signing.
It helps considerably against moisture intrusion, freeze damage, and moss staining on shaded surfaces. Most sealers need reapplication every few years. Wait for the slab to cure fully before the first application, generally at least a month.
Pavers handle ground movement better because individual units can be reset, and they look sharper. They cost more up front and want occasional weed and settling maintenance. On soft, wet ground, both approaches still depend entirely on the quality of the base underneath.
The finished surface should move water away from the building without sending it onto neighboring property or trapping it at a garage. Ask the bidder to show the planned slope and any channel drain before forming. Drainage corrections belong in the scope, not after the slab is poured.
Control joints create planned weak lines so normal shrinkage occurs in straight, less-visible locations. They do not guarantee a crack-free slab. Ask where joints will go, how deep they will be, and whether they are tooled during finishing or saw-cut afterward.
Use the written payment schedule and save final payment until the agreed work, cleanup, joints, and obvious corrections are complete. Concrete still needs curing time, but forms, debris, adjacent damage, and scope completion can be checked before the final balance is released.
