Unilock Construction in San Antonio Heights, CA | Moreno Valley Builders
We provide independent Unilock paver construction and repair across San Antonio Heights, from new driveway installs to re-leveling patios that have settled on clay. Our crews know the four Unilock lines that matter here: Brussels Block, Beacon Hill, Thornbury, and Umbriano. The difference in San Antonio Heights is the slope and the soil. Every paver job we take in the 91784 ZIP starts with a drainage and base assessment, because flat-lot specs fail fast on foothill grades. Call Moreno Valley Builders at (877) 752-3154 for a free estimate that accounts for your lot’s actual conditions.
Why San Antonio Heights Residents Choose Us for Unilock Service
Noel Trevino grew up in the Sunnymead Ranch area of Moreno Valley and has spent nearly three decades building and renovating homes across the Inland Empire. He learned framing, concrete, and mechanical systems at Riverside City College, then spent years tearing out undersized headers and redoing stucco jobs that went over green framing. That background shapes how we approach Unilock work in San Antonio Heights. We don’t trust a spec sheet until we’ve walked the slope.
Our Unilock sales & service work here covers new construction, repair, and re-leveling. We’re an independent contractor, not a Unilock dealer. That matters because we recommend OEM edge restraints and joint sand when warranty-backed performance calls for it, but we’ll also spec a higher-grade geotextile or aggregate base when the lot demands more than the standard detail. On a hillside lot with expansive clay, the base is the system. The pavers are just the top layer.

Common Unilock Construction Problems We Solve in San Antonio Heights
- Edge restraint failure on sloped driveways. We see this constantly on San Antonio Heights’ steeper streets. Plastic edge restraints rated for flat lots let pavers slide downhill under Santa Ana wind load and runoff. We replace them with concrete curbs and Unilock OEM restraints, then reset the field. If the original restraint failed, the base usually needs excavation too.
- Base erosion from downslope stormwater. Winter rain hits clay soil and runs fast. Where a driveway or patio crosses the natural drainage line, water tunnels through the aggregate base and the pavers sink. We regrade, add a geogrid layer, and often install a channel drain at the uphill seam before resetting anything.
- Efflorescence and staining on lighter pavers. Umbriano and lighter Beacon Hill tones show salt migration faster in our hot, dry summers. It’s cosmetic, but it tells you the base isn’t draining the way it should. We correct the drainage, then clean and reseal the surface.
- Root intrusion on older patios. The 1920s to 1950s foothill cottages often have mature trees close to the house. Roots lift pavers at the edges, crack joint sand, and create trip hazards. We saw-cut the edge, remove the invasive roots, install root barrier, and re-level the patio.
- Frost heave and joint sand loss. San Antonio Heights doesn’t get hard freezes like the high desert, but temperature swings plus clay movement still heave pavers at the seams. We re-compact, top up with polymeric sand, and only replace pavers that are structurally cracked.
Unilock Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights is unincorporated. That single fact changes how paver projects get permitted and built here. A paver driveway or patio on a flat Unilock in Upland lot runs through city permitting with minimal grading review. In San Antonio Heights, the county often triggers a grading and drainage review because the lot sits on expansive clay at the base of the San Gabriel Mountains. We’ve handled enough of these reviews to know what the inspectors look for: slope stabilization, setback drainage, and evidence that the paver base won’t send stormwater onto a neighbor’s property. We build those details into the plan from day one. On a project off Crestview Drive, the original Brussels Block pavers had slid downhill after years of runoff and wind. The plastic edge restraint had failed. We excavated, re-compacted the subgrade with a geogrid layer, poured a concrete curb at the base, installed Unilock OEM edge restraints, and reset the pavers on fresh aggregate. We added a channel drain at the uphill seam. That driveway has held through two rainy seasons since.
If the details aren’t right on paper, they won’t be right in the wall. Or in the base.
Unilock Models & Products We Service in San Antonio Heights
We install and repair Brussels Block, Beacon Hill, Thornbury, and Umbriano. Brussels Block and Thornbury are our go-to choices for driveways in San Antonio Heights because they handle load and thermal movement well. Beacon Hill and Umbriano read more contemporary and suit patios, walkways, and pool surrounds. For Unilock repair in Claremont and nearby areas, we match the original paver line whenever it’s still produced. If it’s discontinued, we source close-match aftermarket units and blend them across the field so the patch doesn’t look like a patch. For base material, we use high-quality aggregate and geotextile fabric that meets or exceeds Unilock’s installation guide. For joint sand and edge restraints, we stay with OEM product because that’s where the warranty lives.

AfterUnilock Service Pricing in San Antonio Heights
Every lot here is different, so we price after a site visit. What drives cost on most San Antonio Heights jobs is base correction, drainage work, and access. A steep driveway with a failed base costs more than a flat patio replacement. Here are the ranges we typically quote:
| Service | Typical Range (San Antonio Heights) |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Your free estimate includes a slope and drainage walk, base inspection, and a written line-item quote. We don’t price over the phone without seeing the lot, and we don’t change the number once work starts unless we hit something hidden, like an old septic line or unexpected fill. Call (877) 752-3154 to schedule yours.

FAQs – Unilock Construction in San Antonio Heights
Do Unilock pavers need a concrete base on sloped San Antonio Heights driveways?
For most residential driveways, no. A properly compacted aggregate base with a geogrid layer handles the grade fine. What matters more on a slope is the edge restraint. We use concrete curbs and Unilock OEM restraints at the base and along the sides so the pavers can’t creep downhill. On steeper lots or where the soil is especially reactive, we may recommend a reinforced concrete sub-base. We’ll tell you why in the estimate. Call (877) 752-3154 and we’ll walk the slope with you.
How does San Antonio Heights’ expansive clay soil affect Unilock paver installations?
Clay expands when wet and shrinks when dry, which means the ground under your pavers is moving seasonally. If the base isn’t thick enough and the drainage isn’t right, that movement shows up as cracked joint sand, sunken pavers, and edge separation. We over-excavate and build a deeper base than the flatland standard, and we add geotextile fabric to keep the clay from mixing into the aggregate. On most hillside lots we also add drainage so water doesn’t pool under the pavers. The fix adds cost up front but prevents the re-level every few years.
Can you match an existing Unilock paver for a repair or expansion?
Yes, for current production lines like Brussels Block, Beacon Hill, Thornbury, and Umbriano, and we offer Unilock service in Montclair too. Color lots vary by production run, so for an expansion we’ll order from a recent batch or blend across the field. For discontinued colors, we source close-match units and stagger them so the transition isn’t obvious. If your existing pavers are structurally sound, we’ll always recommend re-sanding and re-leveling before replacement. It saves thousands.
What permits are needed for a paver driveway or patio in San Antonio Heights?
Because San Antonio Heights is unincorporated, San Bernardino County handles permits, not the city of Upland. A paver driveway replacement usually needs a grading and drainage review. A patio may need one depending on size and slope. We handle the permit set, the county submittal, and the inspections. On hillside lots, expect a condition about erosion control during construction. Call (877) 752-3154 and we’ll tell you what your specific project triggers.
How do you prevent weeds and ants from invading Unilock pavers on hillside properties?
Weeds and ants get through joint sand that’s old, thin, or washed out. On a slope, runoff strips joint sand faster, so gaps open up. We re-sweep with polymeric sand that hardens and resists insects, then add a weed barrier below the base where needed. On hillside properties with mature landscaping, we also install root barrier at the edges so tree roots don’t push through from the side. Regular re-sanding every few years keeps the joints sealed.
