West Slope, Oregon Parking Lot Paving & Concrete Services

Hilly neighborhoods along the Portland border with long rains, steep shaded streets, and transit/bike routes. Sealing plus flexible crack-seal limit seepage and thermal cracking on grades.

• Key Consideration: Moss forms rapidly on north-facing curves—treat before sealing.
• Local Tip: Biocide wash and broom clean; add grit to topcoat on steeper slopes.
• Seasonal Insight: Brief cold snaps open joints mid-winter.
• Environmental Factor: Runoff carries fines into intersections during downpours.
• Safety Focus: Chevrons/RPMs for fog-night hill descents to Canyon Rd.
• Maintenance Timing: Seal May–June; quick crack-fill before November rains.
