Unilock Construction in Oak Hills, CA | Polaris Contractors
We provide independent Unilock construction and repair across Oak Hills, CA and nearby communities including Unilock repair in Hesperia – no manufacturer affiliation, just crews who know these paver and wall systems from the base up. What makes our Unilock work different here comes down to one thing: we plan every install around Oak Hills’ raw, unincorporated parcels, not around a flat subdivision lot with city utilities already in place. That changes how we grade, how deep we excavate, and how we sequence the job. If you need a Unilock driveway, patio, or retaining wall built or repaired in Oak Hills, call (855) 473-6535 for a free estimate.
Why Oak Hills Residents Choose Us for Unilock Service
Most contractors in the high desert know one or two paver brands. We’ve worked with Unilock products long enough to know which models hold up on an exposed Oak Hills lot and which ones fight you every year. Brussels Block, Beacon Hill, Rivercrest Wall, U-Cara – we know how each one behaves under intense sun, sustained wind, and winter freeze nights. That’s the difference between a patio that still looks tight five years in and one that’s heaving and spreading by the second spring.
Rick Sondermann, our owner, grew up in Corona del Mar and spent nearly three decades building and renovating homes along the Newport Beach coastline. He learned construction fundamentals at Saddleback College in Mission Viejo, where the estimating and building technology coursework gave him a foundation he still draws on. That background matters here: Oak Hills parcels don’t forgive shallow base work or skipped drainage. Do it right the first time – the second time always costs more.
We’re a full-scope general contractor, which means your Unilock hardscape doesn’t get orphaned from the rest of your project. If the patio ties into a new addition or an ADU, we manage the whole sequence under one contract. One team, full scope. That’s how we work in Oak Hills.

Common Unilock Construction Problems We Solve in Oak Hills
- Joint sand stripped by sustained wind and monsoon sheet-flow. Oak Hills gets strong winds that keep working on paver joints week after week. When sand-joint pavers lose their joint sand, blocks shift and edge restraint starts to separate. We re-sweep with polymeric joint sand and address the base and edge problems that let the shifting start in the first place.
- Efflorescence and sun-fading on lighter-toned pavers. Intense high-desert UV with no shade cover and no irrigation runoff to wash salts through means lighter Unilock colors can chalk and fade unevenly. White mineral deposits bloom across the surface. We clean and re-seal where appropriate, and when a paver line keeps fighting the sun, we’ll tell you which Unilock colors hold up better out here.
- Freeze-thaw spalling and heaving at elevation. Winter nights in Oak Hills drop below freezing, and ground that freezes and thaws will move pavers if the base wasn’t cut deep enough. We see this constantly – drives and patios built to valley frost standards that start heaving within a couple of seasons. The fix is re-excavation to proper desert frost depth, new aggregate, and re-compaction.
- Retaining wall bulge from inadequate drainage and geogrid. Rivercrest and U-Cara walls bulge when wind-driven rain drains off an ungraded raw parcel and saturates the backfill. Without proper geogrid and drainage behind the wall, hydrostatic pressure pushes the face out. We rebuild the base, install drainage, and reset the block rather than capping over a structural failure.
- Base failure on unstabilized or undersized aggregate. Lots in Oak Hills are often raw desert with no prior compaction history. A base built for a suburban backyard won’t hold up here. We re-excavate, lay fresh aggregate in lifts, compact each one, and use geogrid where the soil or slope demands it.
Unilock Service in Oak Hills: What Local Conditions Mean for Your Equipment
Oak Hills is unincorporated high desert in the shadow of the San Gabriel Mountains. Nearly every home sits on a lot large enough to require its own well, septic, and access – there’s no municipal water, no city sewer, and often no paved road frontage. That single fact shapes Unilock construction here more than anything else. A hardscape tied to a new addition or ADU can stall at permit unless the well and engineered septic are certified first. So we sequence Unilock patio and driveway work around that utility sign-off, which a valley crew never has to plan for. We’ve done it repeatedly on parcels along El Centro Road and throughout the 92344 zip code. The pavers go in after the well pass and septic approval clear, because digging a trench line through a fresh Brussels Block driveway to fix an uncertified septic is a cost nobody should eat twice.
On a multi-acre parcel off El Centro Road, we tore out a heaving Brussels Block driveway whose base had been cut too shallow for the freeze nights at this elevation. We re-excavated to desert frost depth, re-compacted with fresh aggregate and geogrid, reset the Brussels Block, and locked the edges with polymeric joint sand so the wind couldn’t strip the joints again. That job taught us exactly what Oak Hills base work has to look like, and we apply that standard on every Unilock install we touch out here.

What drives the cost on an Oak Hills job isn’t the paver price – it’s the base work, the grading, and the access. A raw parcel with no paved driveway approach means bringing in more aggregate, doing deeper excavation, and often working around well and septic setbacks. Your free estimate includes an on-site look at the base, the drainage, and the access path, so you know the real number before anything starts. Call (855) 473-6535 to schedule yours.

FAQs – Unilock Construction in Oak Hills
Yes. A raw parcel with no paved access just means the base work, compaction, and edge restraint have to be done right from the start – which is exactly the kind of site we’re used to in Oak Hills. We grade for drainage, excavate to desert frost depth, and compact the aggregate in lifts so the driveway holds up under both vehicle load and freeze-thaw cycles. Call (855) 473-6535 for a free estimate on your specific parcel.
Walls bulge in Oak Hills because wind-driven rain drains off ungraded raw parcels and saturates the backfill behind the wall. Without adequate drainage and geogrid, hydrostatic pressure pushes the face out, and Rivercrest and U-Cara walls are especially vulnerable when the base was never engineered for that water load. We rebuild the base and drainage rather than capping over the damage, because a bulging wall means the structure underneath has already failed. The honest call is replacement, not a cosmetic fix.
Often, yes. Oak Hills is unincorporated with no municipal sewer or water, so if your hardscape ties to a new addition or ADU, the permit can stall until the well and engineered septic are certified. We sequence our Unilock patio and driveway work around that utility sign-off so you don’t end up cutting through new pavers to fix an uncertified system. Call (855) 473-6535 and we’ll explain how this applies to your project.
We specify Brussels Block and Beacon Hill more often than lighter-toned paver lines for exposed Oak Hills lots, because they resist sun-fading and hide wind-blown dust better over time. Lighter tones chalk and bloom with efflorescence under intense UV and no irrigation runoff to wash salts through. Your choice depends on shade cover, elevation, and exposure – we’ll guide you to the right material rather than defaulting to whatever is in stock.
We use polymeric joint sand and make sure the edge restraint is set so tightly the joints don’t flex and open up. Polymeric sand locks when it cures, which stops sustained high-desert wind from stripping the joints the way ordinary sand gets stripped within a season or two. We also address the base and edge conditions that let shifting start in the first place. For an exact quote on your lot, call (855) 473-6535 – estimates are free.
