Includes: excavation and grading, geotextile fabric (prevents rutting), 4-6 inch gravel base, top layer crushed rock, compaction. Material costs: Crushed rock: $40-50/ton delivered, Pea gravel: $30-45/ton, Quarry spalls: $35-50/ton. Most affordable driveway option while providing good performance.
Best gravel for Snohomish driveways: CRUSHED ROCK (¾ inch): Best all-around choice, excellent compaction, good drainage, long-lasting. Our #1 recommendation. PEA GRAVEL: Smooth rounded stones, comfortable to walk on, good for top layer over crushed base. QUARRY SPALLS: Larger angular rock, excellent for base layer, very stable, best for heavy loads. LAYERED SYSTEM (our method): 3-4 inch base layer of larger rock, 2-3 inch top layer of crushed rock or pea gravel. Avoid: sand (washes away), dirt (becomes mud), round river rock (shifts). We recommend crushed rock for Snohomish climate.
Gravel driveway lifespan: Properly installed: 10-20 years with periodic maintenance, With regular maintenance: Indefinitely (just add gravel as needed). Maintenance needed: Rake and regrade annually: $200-500, Add new gravel every 3-5 years: $300-800, Fill potholes as they appear: $100-300. Snohomish factors: Heavy rain can wash gravel (proper grading prevents), Freeze-thaw cycles can create ruts, Tree roots can disrupt surface. Our installations last longer with proper drainage design and quality materials.
Gravel maintenance: REGULAR (Monthly): Rake to redistribute gravel, Fill low spots and potholes, Edge along borders. SEASONAL (2x/year): Regrade surface with box blade or grader, Add new gravel to thin areas, Ensure drainage ditches clear. EVERY 3-5 YEARS: Add 1-2 inches new gravel over entire surface, Recompact if rutted. TIPS: Keep vehicles in same tracks (prevents rutting), Remove vegetation promptly, Install speed bumps for long driveways. Cost: DIY maintenance (minimal), Professional regrading: $300-800, New gravel: $400-1,200. Much easier than asphalt or concrete maintenance.
YES! Geotextile fabric is essential: Benefits: Prevents gravel mixing with soil underneath, Reduces rutting and potholes dramatically, Improves drainage, Extends gravel life 2-3x, Reduces maintenance costs. Installation: Place fabric after excavation, Overlap seams 12 inches, Pin or stake edges, Add gravel on top. Cost: $0.50-1.00/sq ft (well worth it!). Snohomish clay soils make fabric especially important. Without fabric: gravel sinks into clay, constant ruts and potholes, need frequent regrading. All our installations include proper fabric.
Yes, with proper installation: Requirements for heavy loads (RVs, trucks, equipment): 6-8 inch gravel depth (instead of 4 inches), Larger base rock (2-3 inch quarry spalls), Extra compaction in lifts, Geotextile fabric mandatory, Proper drainage to prevent softening. Our RV/equipment pads: Designed for 10,000+ lb loads, Use commercial-grade materials, Heavy compaction with vibratory roller, Crown for drainage. With proper installation, gravel handles heavy vehicles better than thin asphalt. We’ve built hundreds of RV pads throughout Snohomish County.
