Project Overview
EARTHTEK Paving and Grinding Inc completed this commercial pavement maintenance project for RC Pacific in Sunnyvale, CA. Our crew performed targeted asphalt repair on damaged sections, applied protective sealcoating across the lot, and finished with fresh parking lot striping — restoring the pavement's performance and giving the property a clean, like-new appearance.
This repair-sealcoat-stripe sequence is the most cost-effective way to extend the life of commercial pavement. Repairs stop active failures, sealcoating protects the entire surface from water, UV, and vehicle fluids, and new striping restores safe traffic flow and code compliance — all at a fraction of the cost of repaving, and with minimal downtime for tenants and visitors.
Scope of Work
- Asphalt repair and crack sealing
- Protective sealcoating application
- Parking lot striping and pavement markings
Why This Project Was Needed
Commercial lots in the South Bay take constant traffic and year-round sun exposure. These are the signs that made this maintenance cycle the right call:
- Cracks and localized failures — open cracks let water into the base, where damage compounds; small repairs now prevent full-depth failures later
- Oxidized, gray asphalt — UV exposure dries out unsealed pavement, making it brittle and accelerating cracking
- Faded striping — worn stalls and markings create parking confusion, wasted capacity, and unsafe pedestrian movement
- ADA compliance — accessible stalls, access aisles, and signage markings must stay current to avoid fines and lawsuits
- Tenant and visitor impressions — a worn lot reflects on every business at the property; a maintained one signals professional management
- Asset protection — sealcoating every 2–3 years can double the service life of commercial pavement
Our Asphalt Repair Process
- Lot assessment — Map cracks, potholes, and failed sections across the property; prioritize repairs in drive lanes and high-traffic areas.
- Failed-section removal — Saw-cut and remove damaged asphalt down to stable base.
- Base restoration & patching — Compact the base, then fill, grade, and compact hot mix asphalt patches flush with the surrounding surface.
- Crack sealing — Rout, clean, and fill cracks with hot rubberized sealant to stop water intrusion.
Our Sealcoating Process
- Surface preparation — Clean the entire lot of dirt, debris, and vegetation; prime oil spots so the sealer bonds.
- Sealcoat application — Apply commercial-grade sealer by spray or squeegee in two uniform coats, phased by section so the property stays accessible.
- High-wear reinforcement — Add coverage in entrances and drive lanes where wear is heaviest.
- Curing — Allow 24–48 hours per section before reopening to traffic.
Our Parking Lot Striping Process
- Layout verification — Confirm stall dimensions, drive aisles, fire lanes, and ADA-accessible spaces meet current code before restriping.
- Measuring & marking — Snap reference lines over the cured sealcoat for straight, uniform layout.
- Striping application — Apply traffic-grade paint with a line striping machine for crisp, high-visibility lines.
- Stenciling & specialty markings — Add ADA symbols, directional arrows, crosswalks, fire lanes, and no-parking zones.
- Curing & reopening — Allow paint to dry (typically 30–60 minutes per coat), then reopen the lot.
Equipment Used on This Project
- Skid steer and saw-cutting equipment for repairs
- Plate compactors and rollers for patch work
- Hot rubberized crack sealing kettle
- Sealcoating spray rig and squeegee equipment
- Line striping machine, stencils, and layout tools
- Crew trucks and material transfer
The Result
A protected, refreshed commercial lot for RC Pacific — active failures repaired, the full surface sealed against water and UV damage, and crisp, code-compliant striping restored. The property gained years of pavement life and a clean, professionally maintained appearance without the cost or disruption of repaving.
