Unilock Construction in Running Springs, CA | San Mateo Construction
We provide independent Unilock paver and retaining wall installation across Running Springs, and the one thing that separates our work here is drainage. At 6,000 feet with heavy snow and steep lots, a Unilock system is only as good as the base underneath it. San Mateo Construction installs and repairs Unilock driveways, patios, and walls throughout the 92382 ZIP, and we re-grade and drain before a single paver goes down. Call (855) 901-7266 for a free estimate.
Why Running Springs Residents Choose Us for Unilock Service
We’ve installed Unilock sales & service systems across the San Bernardino Mountains long enough to know exactly how their engineered units behave under snow load and freeze-thaw swings. Noel Carrington, our owner, grew up learning concrete and footing work from his father, and that foundation-level understanding shapes how we approach every paver job. We’re an independent installer, not authorized or endorsed by Unilock, which means we recommend their systems because they perform, not because a contract says we have to.
Most Running Springs work starts with a slope. The original cabins here weren’t built with engineered drainage, so we routinely re-cut grades and daylight drain outlets before laying base aggregate. That’s the step that makes or breaks a paver driveway in this climate. We carry genuine Unilock units, matching edge restraints, and polymeric joint sand, and we stock quality aftermarket base aggregate and geogrid that meets spec for Unilock repair in Lake Arrowhead and surrounding areas. If an existing installation is sound but under-drained, we repair and re-sand rather than tear it out.

Common Unilock Construction Problems We Solve in Running Springs
- Efflorescence bloom and surface spalling. Meltwater refreezes in paver joints during Running Springs snowmelt, pulling minerals to the surface and eventually flaking the top layer of the unit. When the base was underbuilt, this accelerates. We correct the drainage first, then address the surface.
- Joint sand washout and paver heaving. Driveways graded too flat for freeze-thaw cycles let ice lenses form under units, lifting them every spring. We see this constantly on older cabin driveways. Fixing it means re-grading with positive slope and rebuilding the base in compacted lifts.
- Retaining wall block creep on steep lots. Seneca and Brussels Dimensional walls set without engineered geogrid shift under slope load. On a 30-degree Running Springs hillside, a wall without geogrid will start to bulge within a few seasons. We rebuild with proper reinforcement.
- Moss, algae, and staining on shaded north-facing patios. Pine canopy plus snowpack lingering into April creates persistent moisture. Polymeric sand with a proper drainage plane keeps water from pooling, which reduces the staining cycle.
- Failed bases from unpermitted original work. Many mid-century cabins had weekend-warrior paver additions with no base at all. We pull them, re-grade, and install a proper compacted base before laying fresh Unilock units.
Unilock Service in Running Springs: What Local Conditions Mean for Your Equipment
Running Springs’ mid-century cabins were often built as weekend retreats without engineered drainage, so Unilock paver and wall installs here routinely require us to cut and re-grade the original slope and daylight a new drain outlet before any base goes down. That step rarely comes up on flatter, newer lots down in Redlands or Unilock repair in Highland. Here it’s the standard opening move. On a steep lot off the upper stretch of Live Oak Drive, we tore out a heaved Brussels Block driveway where meltwater had been pooling against a pier-and-beam cabin with no real drainage. We re-cut the grade, added a perforated drain daylighting downhill, rebuilt the base in lifts, and re-laid the Unilock units with fresh edge restraint and polymeric sand. The driveway has ridden through two snow seasons without a lifted paver.
Unilock Models & Products We Service in Running Springs
We install and repair the full Unilock line that fits mountain conditions: Brussels Block for dimensional driveways and borders, Beacon Hill for that irregular flagstone-look patio under a pine canopy, Brussels Dimensional Stone for wall systems, and Seneca retaining blocks where you need real structural height. We use genuine Unilock units and their matching edge restraints and polymeric joint sand so the system performs as designed. For base aggregate and geogrid, we source quality aftermarket products that meet or exceed spec. Full replacement only happens when units are spalled through or the base has failed. Otherwise we repair and re-sand.

FAQs – Unilock Construction in Running Springs
No. We’re an independent general contractor who installs Unilock systems because they hold up under mountain conditions. We’re not authorized, sponsored, or endorsed by Unilock, which lets us recommend repair over replacement when that’s the honest call. For an exact quote on your project, call (855) 901-7266.
Sometimes, but not usually in Running Springs. Efflorescence is a mineral deposit drawn out by water moving through the paver. If the water is just surface moisture, it may fade over a season. If it’s coming from trapped meltwater under the pavers, it won’t stop until the drainage is fixed. Call (855) 901-7266 and we’ll tell you which one you have.
Most driveway repairs run three to five working days, weather permitting. Full paver driveway installations on steep lots typically take one to two weeks depending on the drainage scope. Snow season obviously compresses the window, so spring and fall are when most Running Springs homeowners schedule. Call (855) 901-7266 to get on the calendar.
