Unilock Construction in Highgrove, CA | Milpitas Construction
We’re Milpitas Construction, and we provide independent Unilock paver, wall, and step installation and repair across Highgrove’s 92313 zip code. The one thing that separates our Unilock work here from anyone else’s is simple: we’ve spent years resetting pavers on graded pads and canyon-edge parcels where the original drainage was cut decades ago, before the county started scrutinizing slope stability. If your Brussels Block driveway is heaving or your Estate Wall terrace is losing its batter, call (877) 752-4194 for a free estimate. We’re not authorized or sponsored by Unilock, which means we quote every Highgrove job on its own merits, using Unilock’s own matched units where it counts and proven aftermarket base materials where the spec allows.
Why Highgrove Residents Choose Us for Unilock Service
Most Highgrove properties sit on large lots that were graded long before anyone thought about hardscape drainage. That’s the work we know best. Our crews have installed and repaired Unilock Brussels Block, Beacon Hill, Umbriano, and Estate Wall systems across the Box Springs foothills, where summer heat and Santa Ana winds test every joint and edge, and we also offer Unilock in Grand Terrace. Ken Stafford, our owner, grew up around construction and still approaches every job the way he learned it: look at the base first, because the paver is only as good as what’s under it. We spec materials by name, so you know exactly what’s going into your Highgrove home. And because we’re a full-scope general contractor with access to more than 50 brand-name product lines, we can handle the concrete, drainage, and even a new retaining wall on the same contract, not as three separate phone calls.

Common Unilock Construction Problems We Solve in Highgrove
- Efflorescence and salt bloom on Brussels Block and Beacon Hill pavers. Highgrove’s hard irrigation water plus 95 to 105 degree summer heat creates rapid wet-dry cycles that pull minerals to the paver surface. We clean and reseal affected areas, but we also check whether your irrigation overspray is hitting the hardscape, because that’s usually the real source.
- Paver heave and joint sand loss on graded pads. Along the Box Springs foothills, many pads were cut decades ago and the surface drainage was never re-cut after the original retaining wall went in. Water moves under the pavers, the base shifts, and joints lose sand. We re-grade, re-base, and re-sand with polymeric joint sand suited to slope conditions.
- Edge spalling and corner chip on Brussels Block driveway aprons. Highgrove’s ranchette lots often have unpaved-to-paved transitions where vehicle loads and tire scrub concentrate on paver edges. We reset damaged units with Unilock’s matching block and add edge restraints so corners stop breaking.
- Wall block settling and batter loss on Estate Wall terraces. The original sub-base under many Highgrove terrace walls was compacted for a wall built thirty or forty years ago, not for today’s loads. We rebuild the base, reset the block, and restore the batter so the wall leans back into the slope instead of creeping forward.
- Driveway replacement where the old base has failed. When the aggregate below the pavers has turned to dust or the block faces are too spalled to reset, we recommend tear-out and a new Unilock driveway with proper base compaction and edge restraint. We only pull the trigger on replacement when re-laying isn’t the honest call.
Unilock Service in Highgrove: What Local Conditions Mean for Your Equipment
Highgrove sits in unincorporated Riverside County, which means paver driveways and patios on 92313’s canyon-edge parcels are permitted and inspected by the county rather than a city building department. That distinction matters more than most homeowners expect. Hillside pads graded decades ago often require a drainage and slope-stability review before any new hardscape goes down, and the county’s reviewers ask questions a flat-land city inspector would never raise. We’ve been through enough of those reviews to know what gets flagged. A paver patio on a level lot in Riverside might sail through permitting, but the same patio on a graded Highgrove pad above an old retaining wall can trigger a drainage study, a geotech letter, or a requirement to re-cut the swale before the first paver is set, similar to what we see with Colton Unilock service. We plan for that from day one. On a graded pad off the Box Springs foothills, our crew pulled up a heaving Brussels Block driveway apron where the old base had never been re-graded to shed water away from a 1960s retaining wall. We re-cut the slope, re-based with compacted aggregate and geogrid, reset the salvaged block, added Unilock edge restraints, and re-sanded the joints with polymeric sand so runoff now moves off the pad instead of under it. That’s the difference between installing Unilock in Highgrove and installing it in a neighborhood where the ground was never touched.
Unilock Models & Products We Service in Highgrove
We work with the Unilock lines that show up most often on Highgrove properties: Brussels Block for driveways and walkways where a tumbled, classic edge suits mid-century homes, Beacon Hill for larger-format patios and pool decks, Umbriano for a smooth, contemporary finish on slopes, and Estate Wall for terracing and retaining applications. When we repair visible faces and corners, we source Unilock’s own matching units, caps, and edge restraints so courses, colors, and textures stay consistent. For base aggregate, geogrid, and polymeric joint sand, we use quality aftermarket materials that meet or exceed the spec. That keeps your Unilock job honest on cost without cutting corners on what shows. Our access to Unilock sales & service resources means we can pull matching units quickly for Highgrove repairs, not wait weeks for a special order.

FAQs – Unilock Construction in Highgrove
Yes, in most cases Riverside County requires a grading and drainage review for new hardscape on hillside pads, and a new paver driveway over a certain square footage usually triggers a permit. We handle the paperwork and know what the county will ask before they ask it. Call (877) 752-4194 and we’ll tell you exactly what your specific lot will need.
That white bloom is efflorescence, and in Highgrove it’s driven by hard irrigation water hitting the pavers during 95 to 105 degree heat, which creates rapid wet-dry cycles that pull minerals to the surface. We clean the affected units, but we also check your sprinkler throw pattern, because if the overspray keeps hitting the same section of pavers, the bloom will come back, just as we do for Unilock repair in Loma Linda. Call (877) 752-4194 for a free look at your specific situation.
Usually, yes. If the block faces aren’t too spalled and the base is still structurally sound, we re-lay and re-base the existing units, which saves you up to half the cost of a full replacement. We only recommend tear-out when the base has failed or the block faces are too damaged to reset.
We start by checking the condition and compaction of the original sub-base and whether the lower retaining wall is still holding its batter. If the lower wall has settled, we re-compact its base, reset the block, and only then build the Estate Wall terrace above it. Sequencing matters on slopes; putting a new wall on top of a failing one just moves the problem uphill.
We use polymeric joint sand with a high binding agent ratio for sloped patios, because dry Santa Ana winds will strip plain sand out of wide joints within one season. The polymer sets up after wetting and resists both wind erosion and washout. Call (877) 752-4194 if your patio joints are disappearing, and we’ll quote the re-sand, or reach out about Unilock service in Rubidoux.
