Unilock Construction in Loma Linda, CA | Timberline Contractors
We’re an independent contractor installing and repairing Unilock paver systems across Loma Linda, and we also handle Unilock repair in Grand Terrace — the quick answer is this: most Unilock work here succeeds or fails on base preparation and drainage, not the pavers themselves. Loma Linda’s high seismic zone and medical-campus grading rules mean your paver driveway needs a compacted base and slope that would pass scrutiny in few other Inland Empire cities. Call (866) 253-5808 and we’ll tell you exactly what your lot needs.

Timberline Contractors has installed Unilock systems across the Inland Empire for years. We’re not manufacturer-authorized, and we’ll say that plainly. What we bring instead is hands-on knowledge of Unilock’s Unilock sales & service specifications, from base depth to joint sand selection, and we build to those specs on every job. If you’re in the 92350, 92354, or 92357 ZIP codes, we’re local enough to know your street’s drainage pattern before we set the first edge restraint.
Why Loma Linda Residents Choose Us for Unilock Service
Nelson Fung runs Timberline Contractors, and he started learning materials the way a lot of builders do: wrong, then right, then never forgetting the difference. That’s the lens we bring to Unilock work in Loma Linda. We read the manufacturer’s installation guides ourselves. We don’t shortcut the aggregate base. We don’t substitute a generic edge restraint and hope nobody notices.
When a Loma Linda homeowner calls about a shifting paver driveway or a patio with white efflorescence bloom, we already know what we’re likely to find. Overwatered Inland Empire lawns pushing irrigation runoff against a paver edge. A 1960s driveway base that was never compacted to anything resembling a modern spec. Santa Ana wind-driven rain that blew joint sand out of the courses. You get a straight diagnosis, not a sales pitch. And when we do the work, we use genuine Unilock pavers and matching Unilock edge restraint with polymeric joint sand, because mismatched aftermarket units show their color inconsistency within a season.

Common Unilock Construction Problems We Solve in Loma Linda
- Efflorescence bloom on Brussels Block and gray-toned pavers. Loma Linda’s hard water, plus runoff from overwatered lawns and drip lines at the driveway edge, keeps paver surfaces damp longer than they should be. That persistent moisture pulls salts to the surface and leaves a chalky white film. We treat the cause, redirecting water and repairing the drainage path, then clean and re-sand the affected area.
- Joint sand washout after Santa Ana wind-driven rain. When a driveway drains toward the garage instead of the street, stormwater channels through the paver joints and strips the sand. We re-grade the slope where possible, replace the washed-out sand with polymeric joint sand, and correct the drainage so future rains sheet toward the street instead of pooling at the structure.
- Base failure on 1950s-70s Loma Linda driveways. Old concrete or decomposed-granite bases were often laid loose and thin by today’s standards. Those bases hold water under the pavers, and that water plus Inland Empire heat cycles creates rutting and dips. The fix is pulling the affected courses, re-compacting a fresh aggregate base to Unilock spec, and re-laying the pavers. Patching over a failed base just fails again in two summers.
- Chipping and spalling at exposed paver edges. Where a Brussels Block or Town Hall border meets an unmortared transition, foot traffic and equipment loads concentrate on the edge course. That’s where we see the most chipping, especially on Loma Linda lots with narrow driveways that force cars to ride the edge. We re-set and, where the edge takes repeated abuse, recommend a mortared transition or thicker restraint.
- Poor drainage against slab edges and fence lines. Loma Linda’s medical-campus building culture means even residential hardscape gets scrutinized for slope and drainage away from structures. A paver patio that ponds against a slab is a future foundation issue. We correct the base slope and tie in a drainage path that moves stormwater off the lot cleanly.
Unilock Service in Loma Linda: What Local Conditions Mean for Your Equipment
Loma Linda sits in a high seismic zone, and that fact shapes even a residential paver driveway here. A Unilock repair in Colton might pass a neighboring city’s plan checker more easily. But Loma Linda’s medical-campus building culture, rooted in the institutional standards of Loma Linda University Health, means residential hardscape here gets held to a stricter slope and drainage standard. Rainwater has to move off the lot without ponding against a slab or fence line. Add the seismic reality: ground movement is a live consideration, so the base under your pavers has to be compacted better than typical. A loose aggregate base in Loma Linda will settle unevenly within a couple of wet seasons. We build to that standard on every Unilock driveway and patio we install or repair here, because the alternative is pulling up a failed job and doing it again.
Near the university, a mid-century single-family lot came to us with a cracked original driveway that sloped toward the garage. We tore it out, re-based it for a Brussels Block paver driveway, and corrected the slope so runoff sheeted to the street instead of pooling at the garage door. Fresh compacted aggregate base, Unilock edge restraint, polymeric joint sand. The owner got a uniform driveway that shed the last Santa Ana rain cleanly. That’s the Loma Linda difference: grade and base are not optional details here.
Unilock Models & Products We Service in Loma Linda
We install and repair the Unilock lines that hold up best under Inland Empire sun and Loma Linda’s drainage expectations: Brussels Block, Beacon Hill, Cambridge Cobble, and Town Hall.

FAQs – Unilock Construction in Loma Linda
Yes, when the base is built correctly and the right joint sand is used. Unilock pavers are manufactured for UV stability and dimensional consistency, so color fade is minimal. Shifting comes from base failure and sand washout, not heat alone. We compact the aggregate base to spec and use polymeric joint sand so the system stays tight through Loma Linda’s hottest weeks. Call (866) 253-5808 for an exact assessment.
Sometimes, but usually not directly. If the concrete is structurally sound and drains correctly, an overlay is possible. Loma Linda’s older driveways often fail on both counts: cracks from seismic settling and slope that drains toward the garage. We’ll pull the failed concrete where needed, re-base properly, and lay the pavers on a compacted foundation. The pavers are only as stable as what’s under them.
It does. Seismic ground movement rewards a base that’s over-compacted and a drainage path that’s deliberately sloped. Loma Linda’s grading standards reflect that. We build every paver base as if it’ll see ground movement and a hospital-adjacent plan check, because here it probably will.
Those white streaks are efflorescence, and they’re common on Loma Linda lots where hard irrigation water and overwatered lawns keep the paver surface damp. The salts wick through the pavers and bloom on the surface. We clean the surface, address the drainage or irrigation source feeding the moisture, and re-sand the joints. If the water source isn’t corrected, the bloom comes back. Call (866) 253-5808 to have us look at your specific drainage pattern.
Brussels Block and Town Hall for driveways, Beacon Hill and Cambridge Cobble for patios and walkways. Brussels Block’s tumbled edges hide chips better than sharper profiles, which matters on narrow Loma Linda drives where cars ride the edge course. Town Hall’s flat profile suits the mid-century single-family aesthetic common in the neighborhood.
