Unilock Construction in Riverside, CA | Penhallow Remodeling Riverside
Unilock paver and wall work in Riverside calls for a contractor who understands both the product and the ground it sits on. We’re Penhallow Remodeling Riverside, an independent service provider, and our crews handle Unilock paver driveways, patios, and retaining walls across every Riverside neighborhood from the Wood Streets to Orangecrest. The thing that makes our work different here is simple: Riverside’s deep crawlspaces and shifting clay don’t behave like most of Southern California, and we build accordingly. Call (341) 895-1170 to get a written price before any work starts.
Why Riverside Residents Choose Us for Unilock Service
We’ve spent the better part of two decades working as a General Contractor in Riverside and across the Inland Empire, and our crews have put in real hours in the Arlington neighborhood where older homes keep you honest about what’s behind the walls. Trevor Nash, our owner, grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College, where the first lesson was knowing what you’re getting into before you swing a hammer. That’s how we approach Unilock work. We don’t guess at base conditions. We pull back the old pavers, see what’s actually underneath, and then give you a real number. We stock genuine Unilock replacement units for Brussels Block, Town Hall, Richcliff, and Umbriano locally, which means shorter turnaround when you need a repair that has to match existing Units. And because we’re part of the Kingswell family of companies, every job carries the written price, defined arrival window, and 365-Day Done Right Promise.

Common Unilock Construction Problems We Solve in Riverside
Riverside’s inland climate and older housing stock create specific failure patterns we see on Unilock installations. Here are the ones we fix most:
- Efflorescence and surface pitting from hard water: Riverside’s water supply leaves mineral residue that works its way up through Brussels Block pavers, especially installations over ten years old with worn joint sand. The white, chalky deposit isn’t structural, but it looks terrible. We clean the surface and re-stabilize the joints with fresh polymeric sand.
- Fading and UV degradation on south-facing driveways: Summer surface temperatures on Richcliff and Town Hall pavers can exceed 140°F in Riverside. Pigment fades unevenly between shaded and exposed areas. We can replace individual faded units with factory-matched replacements, and we’ll tell you bluntly when a full overlay looks better than spot patching.
- Settling and edge raveling in expansive clay soils: In Riverside’s Wood Streets and Magnolia Center neighborhoods, older homes often sit above deep crawlspaces of stone and redwood, and the void creates soil movement patterns we don’t see in younger tract areas. Paved edges start to drift, walkways sink, paver courses pull apart.
- Weed and ant intrusion after winter rains: Heavy rain followed by rapid drying pulls poly sand joints apart across the city. Weeds seed in the gaps and harvest ants push up through the broken sand, loosening pavers. Re-pointing with stabilized joint material solves most cases.
- Base washout near old foundation drains and crawlspace access: Riverside’s pre-1980 homes often have unconventional drainage paths. Water finds a route into deep crawlspace voids well below grade, taking a paver base with it. This is the Riverside problem most out-of-town contractors miss.
Unilock Service in Riverside: What Local Conditions Mean for Your Equipment
Riverside sits in the Santa Ana wind corridor, and from October through March those winds move three or more days a week on some stretches of the city. It’s not just dust on your patio, it’s airborne grit at 40-plus miles per hour scouring the joints. We see Unilock installations where the top eighth-inch of joint sand is gone within a week, replaced by fine powder that holds water and sprouting weed seed and then the whole paver field starts working loose, one edge at a time. Older Riverside neighborhoods like the Wood Streets and Magnolia Center have original 1920s-era basements and crawlspaces that are unusually deep for Southern California, extending four, sometimes six feet below grade. A new Unilock paver patio poured over shallow base material near one of these voids can settle three or four inches in the first rainy season, a problem a contractor in Corona or Moreno Valley rarely sees because those cities were built on slab foundations with no deep voids. Our crews routinely compact crushed rock in four-inch lifts and lay geotextile fabric where hidden crawlspace voids are suspected, reinforcing the edge restraints before the first paver goes down.
On a 1920s Craftsman on Magnolia Avenue, we came out for our Bathroom Remodeling in Riverside crew to fix a sunken Town Hall paver driveway. The homeowner’s sprinkler system had been overwatering for years, and the original sand base had washed out into the home’s unusually deep basement access, leaving a two-foot depression along the edge. We pulled up the affected field, excavated down to undisturbed soil, installed new geotextile fabric and a half-inch crushed rock base compacted in four-inch lifts, then relaid the salvaged Town Hall units with fresh polymeric sand. We capped the sprinkler heads to redirect water away from the driveway. The surface has stayed flat through two dry Santa Ana seasons.
Unilock Models & Products We Service in Riverside
We work on all four main Unilock product families common in Riverside: Brussels Block, Town Hall, Richcliff, and Umbriano. For discontinued lines like old Rivercrest or Mattoni, we source genuine Unilock replacement units whenever the color and dimensional match matter, which is almost always on a front-facing driveway or patio. For structural components like base panels and geogrid, we use only engineering-specified OEM or equivalent products. We also keep a rolling inventory of matching sand and edge restraints suited to Riverside’s clay and decomposed granite soils, so a small repair doesn’t wait two to six weeks on a factory backorder. If you’re expanding an existing Unilock patio, we’ll match your current units before we cut into the field. Learn more about our Unilock sales & service approach.

FAQs – Unilock Construction in Riverside
Deep crawlspaces under pre-1980 Riverside homes create hollow zones that make the soil above them settle differently than compacted native ground. The fix is deeper excavation, geotextile fabric, and reinforced edge restraints before the base and pavers go down. If the ground shifts later, the edge holds and the interior doesn’t drop into the void.
Yes. We source genuine Unilock replacement units whenever possible, and we match color, dimensions, and mold texture from the existing field. Richcliff fades unevenly on south-facing Riverside patios, so we often blend several replacement units across the seam rather than cluster new pavers in one patch. Call (341) 895-1170 and describe the color shift; we’ll tell you over the phone if a match is realistic.
That’s efflorescence, a cosmetic reaction between water, mineral salts, and cement that’s especially common in Riverside’s hard-water neighborhoods. It’s not structural damage and doesn’t shorten the paver’s life. We clean it with a diluted efflorescence cleaner, never acid, then re-stabilize the joints so water stops wicking upward.
At 25 years, most Unilock walls show splitting, bulging joints, or base settlement, and spot patching a dozen blocks usually costs more per square foot in labor than a clean rebuild. If the wall is under four feet and structurally intact, we repoint and restore it. If it’s taller or showing lean, we recommend a full rebuild with OEM-specified geogrid.
Wind-driven grit wears through the top layer of joint sand fast, and once water enters the gaps, the sand underneath dries and crumbles, exposing the base. We re-point with a stabilized poly sand that sets harder than standard products and holds up through Riverside’s windiest months. A quote for re-pointing is free, just call (341) 895-1170.
