Before & After: Concrete Projects Across the Willamette Valley

Real Results: Concrete Projects from Portland to Eugene

Nothing demonstrates the value of professional concrete work better than seeing the before and after. These projects represent real work completed by Cojo across Oregon's Willamette Valley — from crumbling driveways restored to full function, to brand-new patios that transformed outdoor living spaces.

Every project shown here followed the same approach: thorough site assessment, proper base preparation, quality materials, and skilled finishing. The results speak for themselves.

Residential Driveway Replacements

Salem: Crumbling 30-Year-Old Driveway

A Salem homeowner had been patching their concrete driveway for years. The original slab was only 3 inches thick — below the 4-inch minimum — and had been poured directly on clay soil without an adequate aggregate base.

The problem: Widespread alligator cracking, multiple settled sections, and standing water pooling against the garage. Previous patch attempts were failing.

Our approach:

• Full removal of the existing 720 sq ft driveway
• Excavation of 10 inches of clay soil beneath
• Installation of geotextile fabric to prevent clay migration
• 8 inches of compacted 3/4-minus aggregate base
• 4.5 inches of 4,000 PSI air-entrained concrete
• Broom finish with stamped border
• Proper control joints at 10-foot intervals
• New drainage channel along the garage edge

Result: A driveway engineered for Willamette Valley conditions that will outlast the previous one by decades.

Corvallis: Tree Root Damage Repair

Large street trees had lifted three sections of a Corvallis driveway, creating 3-inch lips and severe cracking. The homeowner wanted to keep the mature oaks.

Our approach:

• Removed three damaged sections (approximately 200 sq ft)
• Pruned roots at safe distance from trunks
• Installed 24-inch deep HDPE root barriers
• Rebuilt base with 8 inches of compacted aggregate
• Poured 5-inch thick replacement sections with fiber reinforcement
• Color-matched to existing concrete (integral color additive)

Result: Level surface restored with root barriers preventing future damage. The oaks continue to thrive three years later with no sign of new root encroachment.

Albany: Complete Driveway and Walkway Renovation

An Albany homeowner wanted to replace their deteriorating asphalt driveway and add a concrete walkway connecting the driveway to the front door and back patio.

Our approach:

• Removed 650 sq ft of old asphalt driveway
• Excavated and rebuilt base to accommodate concrete thickness
• Poured exposed aggregate driveway with broom-finish walkways
• Integrated step-down transitions to the patio level
• Added landscape lighting conduit during base preparation

Result: A cohesive hardscape design that increased curb appeal and connected all outdoor living areas.

Patio and Outdoor Living Projects

Eugene: Backyard Patio Expansion

A Eugene family wanted to extend their small existing patio into a full outdoor entertaining area with space for a grill station, dining table, and fire pit.

Our approach:

• Saw-cut existing 120 sq ft patio at expansion boundary
• Extended to 480 sq ft total area
• Stamped concrete in ashlar slate pattern
• Integral color (sandstone) with charcoal release agent
• Built-in fire pit pad with heat-resistant concrete
• Drainage slope directing water to existing landscape beds

Result: A four-season outdoor living space that flows naturally from the home's interior.

Lebanon: Commercial Entry and Sidewalk

A Lebanon retail business needed their deteriorating front entry and sidewalk replaced to meet ADA requirements and improve customer experience.

Our approach:

• Removed 1,200 sq ft of failing sidewalk and entry pad
• Installed new ADA-compliant ramps with detectable warning surfaces
• Scored decorative pattern in the entry area
• Standard broom finish on walkways for slip resistance
• Proper slope for wheelchair access (1:12 maximum)
• New concrete curb along the parking area

Result: Full ADA compliance, professional appearance, and safe access for all customers. The project was completed over a weekend to minimize business disruption.

Concrete Repair and Leveling

Springfield: Foam Leveling Before and After

A Springfield property had a 400 sq ft concrete patio that had settled 2 inches on one side due to base erosion from a redirected downspout.

Our approach:

• Identified the cause (downspout discharge eroding base material)
• Redirected downspout with an underground extension pipe
• Injected expanding polyurethane foam through 5/8-inch holes
• Raised the settled section to match the house threshold
• Sealed all cracks after leveling

Result: Level patio restored in 3 hours with no demolition. The foam injection filled the void and stabilized the base. No settlement recurrence after two years.

Woodburn: Partial Driveway Replacement

Only one section of a Woodburn driveway had failed — a 10x12 foot area near the street where the base had been undermined by a leaking water service line.

Our approach:

• Coordinated with the city to repair the water line first
• Saw-cut and removed the failed section
• Excavated the washed-out base material
• Installed 10 inches of new compacted aggregate
• Poured 4.5 inches of concrete with dowel bars tying into adjacent sections
• Matched the existing broom finish

Result: The repair is structurally sound and virtually indistinguishable from the surrounding driveway (once it weathers to match the existing color).

Commercial Concrete Projects

Salem: Warehouse Slab Repair

A Salem warehouse had developed significant slab deterioration in the loading dock area from years of forklift traffic. Several areas had spalled to expose the aggregate.

Our approach:

• Removed 800 sq ft of damaged slab sections
• Installed new 6-inch thick concrete with steel fiber reinforcement
• Used high-early-strength mix (6,000 PSI) to minimize downtime
• Applied concrete hardener and densifier to the surface
• Sealed with a penetrating industrial-grade sealer

Result: Loading dock returned to full service in 72 hours with a surface engineered for forklift and heavy equipment traffic.

Corvallis: Retail Parking Area

A Corvallis retail center needed 2,500 sq ft of concrete parking area and sidewalk installed as part of a tenant improvement project.

Our approach:

• Excavated and prepared the subgrade with geotextile fabric
• 10 inches of compacted aggregate base
• 6-inch concrete with welded wire mesh reinforcement
• ADA-compliant parking stall with ramp and detectable warnings
• Saw-cut control joints in a grid pattern
• Applied penetrating sealer for long-term protection

Result: A durable parking surface designed for 30+ years of commercial traffic with full ADA compliance.

What Every Project Has in Common

Regardless of the project size, location, or budget, every Cojo concrete project follows the same fundamentals:

1. Proper base preparation. The base is the foundation. We never cut corners on excavation, material quality, or compaction. On Willamette Valley clay, this means geotextile fabric and adequate aggregate depth.

2. Correct concrete specifications. Air-entrained concrete for freeze-thaw resistance. Adequate thickness for the intended use. Proper water-cement ratio for durability.

3. Precise finishing. Control joints at the right spacing. Proper slope for drainage. Clean edges and transitions. The finish details determine whether the driveway looks professional for decades or starts showing flaws in the first year.

4. Drainage management. Every project considers where water goes. Driveways slope away from structures. Patios drain to landscape areas. Commercial surfaces direct water to engineered catch points.
