Driveway Preparation in Portland, Oregon
A solid driveway starts below the surface. A&N Construction and Excavation provides professional driveway preparation services across the Portland metro area — from removing old driveways to grading and compacting the base for your new one. Whether you're installing a concrete, asphalt, or gravel driveway, we prepare the foundation so it lasts.
What Is Driveway Preparation?
Driveway preparation is the excavation, grading, and compaction work required before a driveway surface can be installed. This includes removing the existing driveway (if applicable), excavating to the proper depth, establishing the correct slope for drainage, compacting the subgrade, and installing a gravel base layer. Without proper preparation, driveways crack, settle, and develop drainage problems within a few years.
Our Driveway Preparation Process
- 1
Existing Driveway Removal
If you're replacing an old driveway, we demolish and remove the existing concrete or asphalt and haul it away.
- 2
Excavation
We excavate to the depth required for your chosen surface material and base layer, typically 8-12 inches total.
- 3
Grading
We grade the base to ensure proper slope for water runoff — typically 1/4 inch per foot away from the house and garage.
- 4
Base Installation
We install and compact a gravel base layer (typically 4-6 inches of crushed rock) that provides the structural support for the driveway surface.
- 5
Compaction
We compact the base with a plate compactor or roller to achieve the density required for your driveway type.
- 6
Handoff
We leave the prepared base ready for your concrete or asphalt contractor to pour or pave.
When You Need Driveway Preparation
Your existing driveway is cracked, sunken, or crumbling and needs replacement. You're building a new home and need a driveway installed. You're widening or extending your existing driveway. You want to convert a gravel driveway to concrete or asphalt. Your driveway has drainage problems and water runs toward your garage or house.
Driveway Preparation Cost in Portland
Driveway preparation costs depend on the length and width of the driveway, whether an existing driveway needs to be removed, soil conditions, and whether fill or gravel needs to be imported. For a standard two-car residential driveway, preparation typically costs $2,000 to $5,000 including removal of the old surface, excavation, grading, base installation, and compaction. We provide exact pricing in your free estimate.
Why Choose A&N
We prepare driveways to the exact specifications your concrete or asphalt contractor needs. Proper grade and compaction are what separate a driveway that lasts 30 years from one that cracks in 3. We coordinate with your paving contractor so the handoff is seamless.
