Unilock Construction in Glen Avon, CA | Square One Builders
We install and repair Unilock paver driveways, patios, and retaining walls across Glen Avon as an independent contractor. The difference here is that we set base, drainage, and jointing to Unilock’s published specs while also handling the unincorporated Riverside County permit path, septic setbacks, and old-lot grading that define this pocket of Jurupa Valley. Call (877) 688-9930 for a free estimate on any Unilock hardscape project.

Why Glen Avon Residents Choose Us for Unilock Service
Most of the Pedley Unilock service work we take on in Glen Avon starts with someone else’s failure. A paver driveway that settled two inches in one winter. A Brussels Block patio where the joint sand washed out after the first real rain. An Onyx retaining wall leaning forward because it was stacked on uncompacted native soil. We get called because we actually read Unilock’s installation specs and we know this area’s soil, drainage patterns, and county inspection quirks well enough to do it right the second time.
Brent Calloway, our owner and Glen Avon General Contractor, has spent nearly three decades working on homes throughout this county, and his approach hasn’t changed: if the base is wrong, the surface will fail no matter how good the paver looks. We use genuine Unilock pavers, wall units, caps, and edging so color lots and coursing match the existing field. For everything under the surface, we spec quality aggregate and geogrid, not whatever the closest landscape supply has on sale.
You’re getting one contractor who takes accountability for the entire hardscape system, from excavation to final jointing. That matters on Glen Avon’s older lots, where the hidden conditions underground make or break the job. You can learn more about how we approach Unilock sales & service across the region.

Common Unilock Construction Problems We Solve in Glen Avon
- Efflorescence and salt bloom on Brussels Block and Beacon Hill pavers. Glen Avon’s older grading often sends water beneath the paver surface instead of away from it. When base wasn’t compacted and water wicks up through the joint sand after winter rain, you get white mineral deposits that can’t just be pressure-washed off. The fix is addressing the drainage path, not scrubbing the surface.
- Polymeric joint sand washing out on driveways graded toward a septic leach field. This is a pattern we see on half-acre Glen Avon lots where the original owner graded runoff toward the back of the property. The sand erodes, pavers start shifting, and edges drop. Re-grading plus proper base correction is the only durable answer.
- Onyx retaining walls bowing or leaning on expansive native soil. Glen Avon’s unengineered original grading often leaves clay-heavy soil that expands when wet. Walls stacked without geogrid and without a compacted base course start tilting within a season or two. We tear them down and rebuild with proper embedment and reinforcement.
- Surface spalling and color fade under Santa Ana wind-driven grit and summer UV. Unilock pavers are dense and well-made, but a sealer applied over damp or dirty pavers traps moisture and causes surface damage. Glen Avon’s heat and wind accelerate the problem. We strip failed sealer, let the surface breathe, and apply correctly or advise you to skip sealing entirely.
- Settled paver edges and cracked perimeter bands on driveways. Without a proper edge restraint, pavers migrate outward with vehicle load. On Glen Avon’s large driveways, the perimeter is often the first thing to fail. We reset edges with proper restraint and compacted base.
Unilock Service in Glen Avon: What Local Conditions Mean for Your Equipment
Glen Avon’s unincorporated county status is the thing most contractors miss. A paver driveway or retaining wall here often needs a separate permit and inspection path from what Eastvale or Jurupa Valley proper would require. More importantly, on lots with septic systems, we have to locate and protect leach fields and drain lines before any base excavation starts. Dig into a leach field with an excavator and you’ve just turned a patio project into a county health department problem. We pull county records, flag the septic boundaries, and design the hardscape so runoff moves away from the system, not toward it. That’s the difference between a patio that lasts twenty years and one that gets flagged the first time an inspector drives by. It’s also why a generic Unilock installer from outside the area gets into trouble here. If you want to know more about what we handle across the Glen Avon service area, we’ve laid out the scope of our local work there.
Unilock Models & Products We Service in Glen Avon
We install and repair the full range of Unilock hardscape products common on Glen Avon properties: Brussels Block for that tumbled, old-world driveway look; Beacon Hill for flagstone-texture patios and walkways; Onyx wall block for segmental retaining walls and seat walls; and Brussels Dimensional or Copthorne for permeable and standard slab applications. When we repair an existing installation, we source genuine Unilock units so the color lot and texture match what’s already in the ground. For base and drainage, we spec quality aggregate and geogrid. We don’t substitute cheap base rock or off-brand joint sand to shave a bid. If a section can be saved, we tell you. If the base is gone or a wall lacks embedment, we tell you that too, straight.

FAQs – Unilock Construction in Glen Avon
Yes, in most cases a new paver driveway or a full replacement triggers a Riverside County permit because Glen Avon falls under unincorporated county jurisdiction. The county also checks for encroachment into drainage easements and septic setbacks. We pull the permit and coordinate inspections through the county building department as part of the project. Call (877) 688-9930 and we’ll tell you exactly what your property triggers.
That white residue is efflorescence, which happens when water moves up through the paver base and evaporates on the surface, leaving mineral salts behind. On older Glen Avon lots, it usually means runoff is getting trapped under the paver surface instead of draining away. Losing joint sand at the same time points to a drainage failure, not a paver defect. We fix the grading and base first, then reset sound pavers with fresh polymeric joint sand.
Yes, and we do it regularly on the half-acre horse properties that make up much of Glen Avon. The county may require a separate permit for retaining walls adjacent to equestrian structures, and we’ll design the wall with proper geogrid reinforcement for the extra load. Onyx wall block is a good fit for corral and barn areas because it handles soil pressure well when built to spec. Call (877) 688-9930 for a site evaluation.
We locate the septic tank, leach field, and all drain lines before any excavation starts, then design the driveway grading so runoff moves away from the system. On Glen Avon’s older lots, original grading often slopes toward the leach field, which is exactly the condition we correct. We keep heavy equipment off the leach field boundary and use hand compaction where needed. This isn’t optional on unincorporated county lots; it’s the difference between passing inspection and failing it.
Usually not right away. Sealing over new pavers in Glen Avon’s summer heat, especially when the surface is hot or has residual moisture, is a common cause of spalling and trapped efflorescence. If a sealer makes sense for your project, we wait for the surface to cure and apply it in the right temperature window. In many cases, we recommend leaving Unilock pavers unsealed here because the product holds up well on its own. Get an honest recommendation by calling (877) 688-9930.
