Unilock Construction in North Tustin, CA | Toolbox Contractors
We install and repair Unilock paver driveways, patios, retaining walls, and walkways across North Tustin as an independent contractor. We source directly from Unilock and work only with ICPI-certified crews. The thing that separates our Unilock work here from anywhere else? North Tustin is unincorporated Orange County, so any paver job that touches grading or drainage runs through OC Public Works plan check, not a city counter. That shapes sequencing, engineering, and timelines on nearly every estate-scale project we take on. If you’re planning a Unilock driveway, patio, or wall in the 92711 ZIP code, call (855) 382-3257 for a free estimate.
Why North Tustin Residents Choose Us for Unilock Service
Norm Castellano runs Toolbox Contractors, and he grew up in the Muscoy area just northwest of San Bernardino, where half the houses on his street were always mid-project and the other half needed to be. He learned the trade through San Bernardino Valley College’s construction technology program, then spent the better part of two decades framing, roofing, and rebuilding kitchens across the Inland Empire. These days he leads a tight crew that has handled everything from Brussel Block driveways to estate-scale front entries on half-acre lots in North Tustin, plus Unilock service in Orange and surrounding areas. We know how Unilock systems hold up under foothill sun, Santa Ana winds, and county plan-check demands. We use Unilock OEM pavers and compatible polymeric sand and edge restraints for repairs and replacements, and we will not color-mismatch an old installation with a non-OEM look-alike. Tell me what you’ve got and I’ll tell you what it actually needs.

Common Unilock Construction Problems We Solve in North Tustin
- Efflorescence bloom on Brussels Block and Beacon Hill surfaces. After hard Santa Ana wind events, white mineral deposits surface on pavers where inland foothill humidity swings and irrigation runoff combine. We address the source, not just the stain, and can re-sand affected joints with compatible polymeric material.
- Polymeric sand joint failure and paver heave on older driveway and patio installs. Many North Tustin homes were built in the 1950s through 1970s, and the original paver bases were compacted for a different drainage reality. When the base fails, pavers shift and joints open. We re-grade, re-compact in lifts, and relay with OEM Unilock pavers.
- Edge restraint displacement at slope transitions. Graded estate lots concentrate runoff at property lines. When edge restraints push out on sloped Unilock installations, the perimeter loses integrity and pavers begin to drift. We reset restraints with proper anchoring and re-establish positive drainage.
- Color fade and surface etching on darker Unilock units. Years of unfiltered inland sun and hard, caliche-laden irrigation water take a toll. We can match replacement pavers to the existing color range and discuss sealing options that slow further degradation without changing the surface texture.
- Driveway replacement where a patch won’t hold. The honest stance we take in North Tustin: if more than about a third of a wall or driveway has settled or heaved, a localized patch is a temporary fix. A full re-base-and-relay is the only repair that lasts.
Unilock Service in North Tustin: What Local Conditions Mean for Your Equipment
Because North Tustin is unincorporated, Unilock driveway and patio builds that touch grading or drainage fall under OC Public Works plan check rather than a city counter. That means a paver job here often needs engineered drainage and slope detail submitted before a single base course is compacted. On tree-lined roads like Newport Boulevard and Cowan Heights Drive, where homes sit on graded half-acre lots, runoff concentrates at property lines and county reviewers want to see a positive drainage path toward a designated infiltration point. It’s a different permitting path than Santa Ana or Tustin proper, and one that shapes scheduling and plan-check timelines on nearly every big project. We have taken that path enough times to know what reviewers flag first and how to front-load the engineering so a driveway or patio doesn’t stall in plan check.
Unilock Models & Products We Service in North Tustin
We work across the Unilock line: Brussels Block (tumbled, dimensional pavers), Beacon Hill (flagstone-look pavers), Uni-Stone (tumbled wall block), and Pisa2 (permeable interlocking pavers). For repairs, we source OEM Unilock units and compatible polymeric sand and edge restraints. We keep common Brussels Block and Beacon Hill color blends moving through our supply pipeline so North Tustin repairs don’t stall waiting on material. For estate-scale driveways and patios, we order directly from Unilock and stage delivery to align with the county plan-check timeline.

FAQs – Unilock Construction in North Tustin
Yes, in most cases you do. Since North Tustin is unincorporated, paver driveway and patio projects that touch grading or drainage run through OC Public Works plan check, not a city building counter. We handle the submittal and engineering coordination for you. Call (855) 382-3257 for an estimate that includes the permit path.
Efflorescence is mineral deposit pushing to the paver surface, and in North Tustin it is driven by Santa Ana wind cycles, humidity swings in the inland foothills, and irrigation runoff. We identify the water source and correct it, then re-sand the joints with compatible polymeric material. For a site-specific assessment, call (855) 382-3257.
Yes. We use OEM Unilock pavers and match the existing color blend as closely as the manufacturing run allows. We will not patch with a non-OEM look-alike that clashes. If the settlement has spread beyond about a third of the driveway or patio, we will tell you the full re-base-and-relay is the only lasting fix. Call (855) 382-3257 for a free estimate.
Paver patios are non-combustible, so they fit well within defensible-space guidelines for canyon-edge properties in North Tustin. The bigger issue is grading and drainage, which OC Public Works will review. We design paver patios to satisfy both fire-safety setback requirements and county drainage expectations. Call (855) 382-3257 to have us look at your lot.
We compact a graded aggregate base in lifts, usually 4 to 6 inches depending on slope and soil, then set bedding sand and Unilock pavers on top with a proper edge restraint. On North Tustin estate lots, we re-grade for positive drainage toward the county-required infiltration point before the base course goes down. This isn’t a shortcut job, and we will not compact over poor soil. Call (855) 382-3257 to schedule a site walk.

Book Your Unilock Service in North Tustin Today
On a tree-lined half-acre ranch estate in North Tustin, our crew tore out a heaved Brussels Block driveway where the original base had failed and the edge restraint had pushed out at the slope. We re-graded for positive drainage toward the county-required infiltration point, re-compacted the base in lifts, reset the OEM Brussels Block on a fresh restraint, and re-sanded the joints. The homeowner got a level, draining driveway that held through the next Santa Ana wind season. That’s the standard we bring to every Unilock job in North Tustin.
