Unilock Construction in Mentone, CA | Toolbox Contractors
We install and repair Unilock paver driveways, patios, and retaining walls across Mentone’s foothill lots, from Pisa2 driveways off Crafton Avenue to Brussels Block patios on the graded parcels above. Most of what we do here comes down to one thing: Mentone’s slopes and winter storm runoff punish shallow paver bases harder than any flat tract in the valley below. We’re an independent Unilock installer, not authorized or sponsored by the manufacturer, and every quote we write includes the base, edge restraint, and drainage as one system. Call (855) 382-3257 to schedule a free estimate.
Why Mentone Residents Choose Us for Unilock Service
Unilock work in Mentone isn’t the same job as Unilock work in Redlands. The lots here rise and fall, the winter rain sheets off the San Bernardino Mountain slopes, and a surprising number of patios sit behind retaining walls that were never engineered by anyone. We’ve built and repaired enough Unilock systems on these parcels to know what fails first and why. This matters because Unilock sales & service only delivers when the contractor understands the ground under the pavers, not just the pavers themselves.
Norm Castellano runs Toolbox Contractors out of San Bernardino, and he grew up in the Muscoy area just northwest of here, where half the houses on his street were always mid-project. He went through the construction technology program at San Bernardino Valley College before spending the better part of two decades doing residential framing, roofing, and full kitchen gut-and-rebuilds across the Inland Empire. When he looks at a Mentone service area paver job, he’s looking at the slope, the drainage path, and what’s under the base. That’s the difference between a patio that lasts fifteen years and one that heaves after two winters.

Common Unilock Construction Problems We Solve in Mentone
Here’s what we see most often on Mentone’s foothill properties.
- Edge restraint failure on graded driveways. When a concrete or polymer edge is set shallow on a sloped driveway, the pavers creep downhill. Santa Ana wind-driven grit works the joints loose, and within a season or two the outside course is fanning toward the road. We pull the edge, set a deeper restraint, and re-lay the field so it stays put under load.
- Base washout after winter storm runoff. Water sheeting off a mountain slope will undercut a compacted aggregate base fast. A driveway that looked flat in July heaves and dips by February because the water has carved a channel through the base from underneath. We re-grade the slope path and re-compact before the pavers go back down.
- Joint sand loss on steep, sun-baked slopes. Decomposed granite blow-sand from the foothills fills paver joints before polymeric sand can fully cure. The result is loose joints, shifting units, and weeds coming up through the gaps. Our fix includes cleaning the joints properly and using a joint sand that actually cures in Mentone’s heat and wind.
- Retaining wall settlement behind patios. This is the one we find on nearly every third job in Mentone. A homeowner-built retaining wall sits behind the patio, unreinforced and never engineered. When we open up the pavers, we find that tier quietly pushing the Unilock courses out of line. The patio fails because the wall fails.
- Premature unit spalling on older driveways. When a base has compacted unevenly over years of heat and runoff, individual pavers take point loads they were never meant to handle. Corners chip, faces spall, and the whole drive looks tired. We replace the damaged units, but only after the base has been corrected underneath.
Unilock Service in Mentone: What Local Conditions Mean for Your Equipment
Here’s the thing that separates Mentone from every flatland city around it: large foothill parcels here are full of homeowner-built and third-party structures. A paver job in Mentone often starts by exposing an unpermitted, non-engineered retaining wall behind the patio. That means the Unilock install only holds once that wall is rebuilt to handle slope load and drainage. We’ve opened up patios off the upper streets near Crafton Avenue where the retaining tier behind the pavers was nothing but stacked block and hope. The Unilock courses above looked fine from the lawn, but underneath, the whole field was creeping forward a quarter-inch every wet season. Contractors offering Unilock service in Redlands don’t factor this in because they don’t see it. We do, because it’s half of what we walk up to in the 92359 ZIP.
Unilock Models & Products We Service in Mentone
We work with Pisa2, the tumbled-edge paver that shows up most often on Mentone driveways and patios. We also build and repair Brussels Block, the traditional tumbled paver that handles foot traffic well but still needs a proper edge on a slope. Estate Wall is our go-to for segmental retaining walls, and Beacon Hill is the flat-profile choice when a homeowner wants a smoother paver with a flagstone face mix. When we repair a run, we source genuine Unilock units and their matching edge restraints and caps so color and dimension stay consistent with the existing field. We use quality compacted aggregate base and polymeric joint sand rather than bargain substitutes. When a run is only settled or edge-failed, we lift, re-base, and re-lay the existing pavers. Full replacement is reserved for crushed or spalled units or a base that can’t be corrected.

FAQs – Unilock Construction in Mentone
Yes, and we do it regularly in Mentone. A graded foothill lot usually means a load-bearing question: what’s above the wall, what’s behind it, and where the water wants to go when it rains. We build Estate Wall systems with proper drainage and a base that accounts for slope pressure. If we find an existing wall that was never engineered, we rebuild it before the Unilock courses go back down. Call (855) 382-3257 and tell us what you’ve got and we’ll tell you what it actually needs.
No. We’re an independent Unilock installer. That means we’re not tied to Unilock’s warranty program or their dealer pricing. What we offer is the freedom to repair or replace only what actually needs it, using genuine Unilock units and matching edge restraints and caps so the repair blends with the existing field.
We source genuine Unilock paver units and their matching edge restraints and caps. For base and joint materials, we use quality compacted aggregate and polymeric joint sand that holds up to Mentone’s summer heat, Santa Ana winds, and winter slope runoff. We don’t cut the paver itself with a bargain substitute.
For a typical paver patio repair, plan on two to four days depending on what we find underneath. A full driveway replacement with re-grading on a sloped lot runs longer, usually five to eight working days, plus dump time if we’re removing old concrete or a failed base. We sequence the job so your access is blocked as little as possible. Call (855) 382-3257 for a schedule specific to your project.
A Unilock paver driveway in Mentone typically runs $7,000 to $18,000 depending on slope, square footage, and whether the existing base can be salvaged. A full driveway replacement, including tear-out and re-grading, typically lands between $5,000 and $14,000. If your lot has a failed retaining wall behind the drive, that work is quoted separately. Estimates are free. Call (855) 382-3257 to get an exact number for your property.
