Unilock Construction in Highgrove, CA | Timberline Contractors
We install and repair Unilock paver systems across Highgrove, from Brussels Block driveways to Umbriano patios and Turfstone permeable grid. The work here is shaped by one thing most contractors from outside the area miss: Highgrove is unincorporated Riverside County, so every paver job runs through county permitting, and a lot of the yards we work in sit on split-off citrus and dairy parcels with private wells and septic lines crossing exactly where you’d want to lay a patio. That changes how we grade, where we put edge restraint, and how we build the base. If you’re pricing Unilock work in Highgrove, call us at (866) 253-5808 for a free estimate, and we’ll walk the site before quoting.
Why Highgrove Residents Choose Us for Unilock Service
We’ve been laying Unilock systems long enough to know the difference between a paver that failed and a base that was never built right in the first place. Most Unilock problems in Highgrove aren’t the paver. They’re what’s underneath. Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years on residential and commercial builds across the LA basin before running Timberline Contractors. He’s the first one to tell a homeowner that replacing the pavers without fixing the base is just paying for the same failure twice. Do it right the first time or explain yourself twice.
We’re an independent Unilock installer, not an authorized or sponsored dealer. That’s not a technicality. It means we can tell you when a Turfstone grid is the wrong call for a dusty Highgrove yard or when a concrete slab would outlast any paver system on a steep west-facing slope. We carry OEM-correct polymeric joint sand, edge restraint, and geotextile separation fabric for fast turnaround on Highgrove jobs, and our crews know the county’s inspection sequence well enough to keep your project moving.

Common Unilock Construction Problems We Solve in Highgrove
- Rutting and sett rotation on Brussels Block driveways. The small-format tumbled setts look great but demand a properly compacted base. When the base is built to a light residential standard and the driveway carries a full-size truck or trailer, the setts rotate and ruts form. We see this constantly on Highgrove ranch properties where owners park work vehicles or horse trailers. The fix is lifting the course, rebuilding the base, and relaying with proper compaction, not just adding sand.
- White efflorescence bloom on Umbriano and smooth slabs. Highgrove’s hot, dry summer pulls moisture up through the paver, and the first winter rain carries salts to the surface, leaving a chalky white bloom. Homeowners often think the finish is defective. It’s not. It’s a moisture issue, and we can clean it and adjust the base drainage to reduce recurrence.
- Edge and joint sand loss on slopes at the foot of the Box Springs Mountains. Santa Ana winds and sheet flow during winter rains strip joint sand out of paver systems on sloped Highgrove lots. Once the sand goes, the setts start shifting. Edge restraint and a re-sand with the correct polymeric product restores the system, but the restraint has to be anchored properly or the same thing happens next year.
- Turfstone and permeable paver clogging from windblown dust. Highgrove’s dry, dusty conditions push fine sediment into permeable grid openings until infiltration drops and water ponds at low points. Permeable systems need periodic vacuuming and occasional media replacement here, far more than they would in a coastal climate. We inspect and service these systems before they become a drainage liability.
- Driveway replacement on split-off parcels with unknown base history. Highgrove’s older housing stock includes lots that were split from citrus and dairy land decades ago. A lot of those driveways were never permitted, never documented, and never built to a spec anyone wrote down. When a paver driveway fails on one of these parcels, the whole base usually needs to come out. We work with the county’s records to figure out what’s actually under the surface before we quote.
Unilock Service in Highgrove: What Local Conditions Mean for Your Equipment
Here’s the part that separates Highgrove from Riverside and Moreno Valley when it comes to Unilock work. Highgrove is unincorporated Riverside County, so a paver driveway or patio here is permitted and inspected through the county building department, not a city. That’s more than a paperwork detail. On split-off citrus and dairy parcels, the paver edge often meets private well and septic infrastructure routed across the same yard. We’ve had jobs where the leach field sits ten feet from where the homeowner wanted a U-shaped driveway, and the county’s setback requirements changed the entire layout. A contractor who only works in incorporated cities won’t think to check well logs and septic as-builts. We do, because in Highgrove it’s routine. The result is a paver system that gets approved the first time and doesn’t create a five-figure septic repair three years later.
We tore out a rutted Brussels Block driveway on a split-off ranch lot near the Box Springs foothills in Highgrove, where the old base had been compacted to light-duty only. Standard loads had rotated the setts and the county permit file showed no base spec at all. We re-graded, rebuilt with geotextile and proper compaction, and re-laid the original units with fresh edge restraint and polymeric sand. The pavers were fine. The base was the failure.
Unilock Models & Products We Service in Highgrove
We work with the full range of Unilock product lines commonly installed across Highgrove: Brussels Block tumbled setts, Beacon Hill flagstone-look pavers, Umbriano smooth-faced slabs, and Turfstone permeable grids. Unilock doesn’t sell pavers as user-replaceable parts, so the honest repair work happens at the base layer. We stock OEM-correct polymeric joint sand, edge restraint, and geotextile separation fabric locally for fast Highgrove turnaround. When a course has pulled, we lift and relay rather than overlay, which means the repaired area actually stays level. If a different paver or even a different material would serve you better, we’ll say so before you spend a dollar.

FAQs – Unilock Construction in Highgrove
Yes, in most cases. Highgrove is unincorporated, so Riverside County’s building department handles permitting and inspection for hardscape work that meets the county’s size and structural thresholds. A patio over a certain square footage, a driveway that changes drainage patterns, or any paver work near septic infrastructure will typically trigger a permit. We pull the permits ourselves and manage the inspections, so you don’t have to navigate the county’s process alone. We also offer Colton Unilock service with the same full permit support. Call (866) 253-5808 and we’ll check your specific parcel before you plan a thing.
That white haze is efflorescence, not a failed finish. Highgrove’s hot, dry summers draw moisture up through the paver, and when winter rain arrives, the salts crystallize on the surface. It’s especially common on Umbriano and other smooth-faced slabs. We can clean it, but the real fix is usually drainage at the base layer. We’ll evaluate the patio, identify the moisture path, and correct it so the bloom doesn’t recur every season.
Yes, faster than in coastal or wetter climates. Highgrove’s windblown dust and dry conditions push fine sediment into the permeable openings, and over time infiltration drops until water ponds at low points. We recommend a maintenance schedule that includes vacuuming and occasional media replacement, and we service these systems before they fail. If you’re considering turfstone but want an honest assessment of the upkeep for this specific lot, or need Unilock repair in Loma Linda, call (866) 253-5808 for a free estimate.
Almost never. Brussels Block setts are dense and durable. The problem is almost always the base underneath, especially on Highgrove lots where the original driveway was compacted to a light-duty standard and the loads are heavier than the installer planned for. We lift the affected courses, rebuild the base with proper compaction and geotextile, and relay the original units. The pavers go back in, the ruts stay gone.
More than most homeowners expect. On split-off citrus and dairy parcels, private well heads, septic tanks, and leach fields often run through the same yard where you want the patio or driveway. County setbacks apply to that infrastructure, and a paver system has to work around it without disrupting drainage or access. We check county records and site conditions before we quote, so the design accounts for what’s underground, not just what’s visible. Call (866) 253-5808 to schedule your free estimate.
