Unilock Construction in Muscoy, CA | Square One Builders
Unilock construction in Muscoy comes down to two things: knowing the paver systems inside and out, and understanding what this unincorporated county island does to them. We’re Square One Builders, and we’ve been installing and repairing Unilock driveways, patios, and retaining walls across Muscoy long enough to know the wind and heat here punish shortcuts. Call us at (877) 688-9930 when your pavers start moving or your wall leans toward the wash.
We’re an independent construction firm. Not a Unilock dealer. Not a manufacturer-authorized shop. What we are is a Muscoy General Contractor who has torn out enough failed Unilock work here to know exactly what proper bedding, compaction, and edge restraint look like in this specific corner of San Bernardino County.
Why Muscoy Residents Choose Us for Unilock Service
Brent Calloway, our owner and general contractor, has spent nearly three decades working on homes where the structural work has to be as clean as the finish. He learned it the slow way, through the Construction Technology program at Golden West College and then years of hauling material and reading plans in parking lots until the work made sense. That’s the standard we bring to every Unilock project in Muscoy.
We spec Unilock’s own edge restraints, caps, and polymeric sand, not whatever generic joint sand is cheapest at the supply yard. Muscoy’s wind-driven dust will scour cheap joints inside two summers. We plan for that from day one. When a paver field shows isolated damage, we handle Unilock service in Crestline-style repairs and re-sand rather than push a full replacement. But when base failure runs wide, we tell you straight: it’s a rebuild with proper geogrid and drainage, or you’ll be calling us again in three years.
If you need Unilock sales & service handled by one accountable team, that’s what we do. One contract, every system, from the ground up.

Common Unilock Construction Problems We Solve in Muscoy
- Wind-blown sand scouring paver joints. The wash and open ground around Muscoy feed loose grit into anything flat. Sand and dust from the wash abrade joint sand and open gaps between Unilock pavers, which leads to shifting and rutting on driveways and patios. We re-excavate, re-compact, and re-sand with polymerics designed to resist that specific abrasion.
- Brittle polymeric sand on west-facing surfaces. Intense summer sun and rapid drying cause polymeric sand to cure brittle and crack, especially on west-facing Unilock Brussels Block surfaces. That loosens joints within a season or two. We adjust the watering and set time for Muscoy’s heat and direct sun exposure.
- Settlement and lippage on older lots. Improper base compaction on Muscoy’s older, sometimes unpermitted lots leads to settlement and lippage across Unilock Beacon Hill or Thornbury installations. We pull the affected field, fix the base, and reset the pavers so they sit flat again.
- Undermined edge restraint on retaining walls. High winds funneling through the Cajon Pass can undermine edge restraint on Unilock Estate Wall when the wall wasn’t engineered for uplift and lateral loads. We rebuild with proper geogrid, drainage, and edge restraint that actually holds.
- Heaved driveways from native-soil base. On large county parcels, we regularly see Unilock Brussels Block driveways laid directly on native soil, no compaction, no Class II base. Wind-blown sand scours the joints and the pavers rock underfoot. This is a full excavation and rebuild. No patch job fixes it.
Unilock Service in Muscoy: What Local Conditions Mean for Your Equipment
Because Muscoy is an unincorporated county island, any Unilock hardscape that touches a shop, addition, or fence line often requires county building review and parcel-map verification before we can set base. That’s a step that doesn’t exist for tract homes inside San Bernardino city limits. Your lot might have an add-on room from the 1980s with no record, or a shop built before the county tightened its rules. When your new Unilock paver driveway butts up against that structure, the county wants to know what’s existing and what’s new. We handle that paperwork-first step so the project doesn’t stall after excavation.
On a large county parcel off Cajon Boulevard, our crew handled Unilock repair in Highland territory and tore out a heaved Brussels Block driveway that had been laid on native soil without compaction. Wind-blown sand had scoured the joints and the pavers rocked underfoot. We re-excavated to 6 inches, compacted Class II base in lifts, set OEM edge restraint, and re-laid the Brussels Block with Unilock polymeric sand. Then we documented the existing shop footprint for the county’s records so the homeowner could legalize the outbuilding at the same time. That’s the kind of dual-purpose job you only run into in a place like Muscoy.

Unilock Models & Products We Service in Muscoy
We work with the Unilock lines that actually show up on Muscoy properties: Brussels Block, the classic tumbled paver for driveways and patios; Beacon Hill, a flat-faced unit good for clean lines; Thornbury, a larger-format paver that speeds up big patio layouts; and Estate Wall, the block system for retaining walls and short seat walls. We treat them differently, because they fail differently here.
We use Unilock’s own OEM edge restraints, caps, and polymeric sand specified for each paver line. We avoid generic joint sand that fails in desert wind. If we need to match an older Brussels Block field that was partially replaced years ago, we measure the original color and take a sample before ordering, so the Unilock repair in Rialto and surrounding areas doesn’t look like a patch. What’s stocked locally for fast Muscoy turnaround is the common base and sand, with pavers ordered per job to match color lots correctly.

FAQs – Unilock Construction in Muscoy
In many cases, yes. Because Muscoy is unincorporated San Bernardino County land, hardscape that touches a structure, alters drainage, or sits on a lot with unpermitted build-outs often triggers county review. We determine what’s needed before we dig, and we include the permit work in our scope.
Two reasons, usually: wind-driven sand from the wash abrades the joints, and the intense summer heat bakes the sand before it cures properly. We re-sand with the right product and set schedule for the surface’s sun exposure, then edge-restrain so the joints don’t keep opening up.
Yes, we can get close. Color lots change over time, so we take a sample from your existing field and order to that sample rather than assuming the new lot will match. The repair won’t be invisible, but it won’t look like a patch either. Call (877) 688-9930 if you want us to look at it.
We check what the county has on file, then we inspect what’s actually there. If prior grading was done without permits, the wall typically needs engineering before rebuild. We rebuild with proper geogrid, drainage, and OEM Estate Wall units so the wind and slope don’t take it down again.
Brussels Block holds up well if the base and edge restraint are done right, because its tumbled profile hides minor movement better than flat-faced lines. For patios with full sun, Beacon Hill and Thornbury work if the polymeric sand is set for heat. The paver matters less than the prep. Call (877) 688-9930 for an exact quote, estimates are free.
