Unilock Construction in Mentone, CA | Polaris Contractors
We’re an independent Unilock installer serving Mentone and the San Bernardino Mountain foothills, not a manufacturer-authorized dealer. That distinction matters here: most paving crews working Mentone lots learned their trade on flat suburban ground down in Redlands or Highland, and it shows in the failures we get called to repair. If you’re planning a paver driveway, patio, or retaining wall in Mentone, call (855) 473-6535 for an estimate from a crew that understands what this terrain actually demands.
Why Mentone Residents Choose Us for Unilock Service
Our crews have laid Unilock pavers, walls, and fire-feature elements across Mentone’s uneven, wind-exposed lots for years, and we’ve also handled Yucaipa Unilock service calls from nearby foothill homeowners. We work directly from Unilock’s published installation specs and ICPI best practices, not from a dealer badge. Rick Sondermann, our owner, learned construction at Saddleback College and has spent nearly three decades building and renovating homes across Southern California. His father was a finish carpenter who believed in doing something once and doing it right. That philosophy shapes every base we compact, every joint we fill, and every drainage detail we specify on a Mentone slope. When you call us, you get one accountable team from the roof down to the pavers, not a patchwork of subs who’ve never seen a wildland-urban interface inspection.

Common Unilock Construction Problems We Solve in Mentone
- Efflorescence bloom on grey-toned pavers. Mentone’s hard irrigation water, combined with dry Santa Ana cycles, draws mineral salts to the surface of Brussels Block and Olde Quarry units as a chalky white film. It looks like a defect. It’s usually water chemistry, and we know how to treat it and adjust the irrigation so it stops coming back.
- Sand-joint washout on sloped driveways and patios. Mountain-grade runoff doesn’t get captured on the larger, uneven lots above the valley floor. When bedding sand washes out from under Unilock pavers, the units migrate, heave, and the edge eventually collapses. We rebuild the base with proper drainage, not just re-sand the joints and hope.
- Retaining wall lean or bulging on Estate Wall and SienaStone systems. Mentone’s stepped, slope-cut lots put real lateral pressure on walls. Built without geogrid reinforcement and proper drainage behind the block, a Unilock wall will start leaning within a few seasons. We rebuild them with the reinforcement Unilock’s own specs call for.
- Ember and UV degradation on wall caps and pillar units. Along the wildland-urban interface, caps that aren’t rated for this exposure crack and spall under intense heat and sunlight. Joint sand erodes under wind-driven debris. We spec caps and polymeric sand that hold up where defensible space meets hardscape.
- Paver migration where runoff off the mountain isn’t intercepted. Mentone sits at the foot of the San Bernardino Mountains, and flash-flood runoff moves fast. Without a proper swale or channel drain at the top of a paved slope, water gets under the pavers and pushes them downhill. That’s a base problem, not a paver problem.
Unilock Service in Mentone: What Local Conditions Mean for Your Equipment
Here’s the one thing most contractors miss until the County stops the job: Mentone is unincorporated, so paver and wall projects are permitted through San Bernardino County building and fire, not a city building department. That means your Unilock hardscape plans get reviewed for defensible-space and ember-resistant detailing alongside the roof. A crew used to Redlands or Highland permitting won’t think to spec a SienaStone pillar setback that satisfies the WUI inspector. We do. On a slope-cut lot off Crafton Avenue, our crew tore out a heaved Brussels Block driveway apron where runoff had washed the bedding sand clean out. We lifted the sound units, rebuilt the base with drainage and geogrid, re-set them with fresh polymeric joint sand, and tied the new edge into a SienaStone pillar that met the County’s WUI defensible-space setback. That driveway has held through two Santa Ana seasons since. Do it right the first time – the second time always costs more.
Unilock Models & Products We Service in Mentone
We install and repair the full Unilock line relevant to foothill properties: Brussels Block and Brussels Dimensional for driveways and patios, Beacon Hill for a more formal joint pattern, Estate Wall for structural retaining walls, SienaStone for wall and pillar systems, and Olde Quarry for walls with a split-face texture. For repairs, we source genuine Unilock units and Unilock-recommended polymeric joint sand and cap adhesives so color and dimensional match is exact. Where the spec permits, we use quality aftermarket geogrid, drainage aggregate, and base materials. No reason to pay a brand premium for buried stone. Pavers that are sound get lifted, re-based, and re-set. Only cracked, spalled, or discontinued units get replaced, because full replacement on a Mentone slope is usually a base problem wearing a paver costume.

FAQs – Unilock Construction in Mentone
Yes. Mentone is unincorporated, so San Bernardino County building and fire review your paver and wall plans, and the WUI overlay means they check for defensible-space setbacks and ember-resistant detailing alongside the hardscape. We handle that paperwork and design around it from the first site visit. Call (855) 473-6535 if you’re unsure whether your project triggers review – we’ll tell you straight.
In Mentone, it’s almost always runoff washing out the bedding sand from below, not the wind stripping the joints from above. Santa Ana winds make the symptom visible, but the water off the mountain is doing the damage. We rebuild the base with proper drainage and use a polymeric sand rated for sloped, wind-exposed applications. Call (855) 473-6535 for an assessment before the pavers start migrating.
No. It’s efflorescence, and in Mentone it’s driven by hard irrigation water meeting dry Santa Ana evaporation cycles. Grey-toned units like Brussels Block and Olde Quarry show it more. We can treat the surface and adjust your irrigation so it stops recurring. The pavers themselves are fine.
Usually, yes. If the units are sound – no cracks, spalling, or discontinued patterns – we lift them, rebuild the base with correct drainage and compaction, and re-set them with fresh polymeric joint sand. You save the cost of new pavers and get a patio that behaves like it was just installed. Full replacement is for units that can’t be salvaged, not for base failures.
When they’re built with geogrid reinforcement and drainage behind the block, Estate Wall and SienaStone systems hold up well on Mentone’s stepped, slope-cut lots. When they’re built like a flat suburban garden wall, they lean and bulge within a few seasons. The difference is in the base and the reinforcement, not the block itself. Call (855) 473-6535 if you see a wall starting to move – catching it early is a repair, not a rebuild.
