Unilock Construction in Midway City, CA | Timberline Contractors
We provide independent Unilock paver installation and repair across Midway City, California, including driveways, patios, walkways, and the structural issues that surface years after the original pour. What makes our work different here: Midway City is unincorporated Orange County, so every Unilock layout we build gets checked against OC Public Works zoning and legal-nonconforming-lot setback rules, not a city counter. That changes base depth, edge restraint, and drainage decisions in ways a contractor working one block over in Huntington Beach never has to think about. Call (866) 253-5808 to schedule a free estimate.

Why Midway City Residents Choose Us for Unilock Service
Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years on residential and commercial builds across the LA basin before founding Timberline Contractors. He’s the guy who will tell you exactly why your paver driveway is sinking at the apron and exactly what it costs to fix it right. Our team has laid Unilock Brussels Block, Beacon Hill Flagstone, Holland Stone, and Copthorne across the small post-WWII lots that make up most of Midway City, and we’ve rebuilt enough failed paver bases here to know where shortcuts show up first. We are an independent installer, not authorized or sponsored by Unilock, and we follow the manufacturer’s written installation guidelines on every job. Our Unilock sales & service work starts with a site check and a straight answer, not a brochure.

Common Unilock Construction Problems We Solve in Midway City
- Edge restraint failure and paver spread on driveways. On narrow Midway City lots, the toe of the base often ends up too thin against a county-required setback line. The edge restraint pops, pavers migrate outward, and the driveway edge turns into a loose mess within a season or two. We rebuild the base with proper geotextile and set Unilock edge restraint on both sides.
- Efflorescence and loose joint sand on shaded north-facing patios. The marine layer sits over Midway City most mornings, and patios tucked behind rear additions never get enough sun to dry out. Moisture wicks up through the pavers, leaving that chalky white film, and the joint sand stays damp and washes out. We address the sub-base drainage first, then re-sand with Unilock’s recommended polymeric joint sand.
- Rutting and settlement over old garage-conversion aprons. Midway City has a lot of converted garages, and the original slab or fill underneath the paver apron was rarely compacted in lifts. Brussels Block and Holland Stone start to rut where the third car parks every day. We pull the pavers, compact the sub-base properly, and re-lay the same material whenever the base can be salvaged.
- Santa Ana wind grit and joint erosion. Exposed driveways in Midway City take a beating during wind season. Fine grit blasts the joint sand out, and if polymeric sand was skipped on the original install, weeds follow. We re-sand with Unilock’s polymeric product and check the edge restraint while we’re at it.
- Driveway replacement when the sub-base is gone. Sometimes the base is so far gone that salvaging pavers doesn’t make sense. In Midway City, we often see this on lots where decades of over-parking and county drainage issues have undermined the base. Full replacement is recommended only when the sub-base or a setback issue kills the layout completely.
Unilock Service in Midway City: What Local Conditions Mean for Your Equipment
Because Midway City is unincorporated, our Unilock driveway and patio layouts are checked against OC Public Works zoning and legal-nonconforming-lot setback rules rather than a city counter. That means a paver apron or widened driveway that a Huntington Beach crew would pull without a second thought can require a county variance before we set base. On a 1950s stucco bungalow lot off Hazard Avenue, the homeowner wanted a widened Unilock Brussels Block driveway apron for a multi-generational household parking a third car, but the existing garage sat inside the county’s nonconforming setback. We pulled the layout tight to the legal line, rebuilt the base in compacted lifts, set Unilock edge restraint on both sides, and sweated the drainage away from the rear ADU so the marine-layer runoff didn’t pond at the joint line. That’s the difference between a paver job that survives county scrutiny and one that gets flagged two years later when the homeowner tries to sell. For details on how we cover the area, see our Midway City service area page.
Unilock Models & Products We Service in Midway City
We install and repair the full range of Unilock in Westminster and surrounding areas, including concrete pavers common on Midway City lots: Brussels Block, Beacon Hill Flagstone, Holland Stone, and Copthorne in both standard and permeable formats. Our parts approach is straightforward: we use Unilock’s own edge restraint, joint sand, and recommended geotextile and base materials so the system stays under the manufacturer’s installation guidelines. Existing pavers get salvaged and re-laid wherever the base can be rebuilt. Full replacement only happens when the sub-base fails or a county setback issue forces a new layout. We keep common Unilock edge restraint and polymeric sand stocked for fast Midway City turnaround, so a repair doesn’t stall waiting on a distributor.

FAQs – Unilock Construction in Midway City
Does Midway City’s unincorporated status change how you install a Unilock paver driveway? Yes. Midway City goes through OC Public Works, not a city building department, and many lots are legal-nonconforming. That means a standard driveway widening can require a county variance before we set base. We handle the plan check and variance paperwork so the paver work doesn’t get held up at inspection. Call (866) 253-5808 to find out if your lot triggers a variance.
Can you match Unilock Brussels Block that’s already on my Midway City patio? If the pavers are structurally sound, yes. We salvage and re-lay the original Brussels Block wherever the base can be rebuilt. If the base is shot but the pavers are fine, we re-lay the same material on a new compacted base. Replacement pavers are ordered from Unilock distributors in matching color and size.
Why do pavers on shaded patios behind rear additions in Midway City go chalky? That’s efflorescence from marine-layer moisture wicking up through the pavers and leaving salt deposits on the surface. The patio behind a rear addition never gets enough sun to dry out. We fix the sub-base drainage first, then address the surface. Sealing alone won’t stop it if the drainage underneath is the problem. Call (866) 253-5808 and we’ll take a look.
My neighbor across the street is on a Huntington Beach permit – does that affect my Unilock repair in Huntington Beach or my project? Yes, and it’s one of the quirks of Midway City. The county line runs right through this area, so your project goes through OC Public Works while your neighbor’s goes through Huntington Beach’s building department. The setback, drainage, and variance rules are different. We’ve worked both sides, so we know where the differences bite.
Do Santa Ana winds damage Unilock paver driveways in Midway City? The winds themselves won’t crack quality concrete pavers, but the grit they carry erodes joint sand fast. If polymeric sand was skipped on the original install, the joints open up and weeds follow. We re-sand with Unilock’s polymeric product and check the edge restraint during the annual dry season. Call (866) 253-5808 if your joints are disappearing after wind events.
