Unilock Construction in Corralitos, CA | Daly City Construction
Daly City Construction provides independent Unilock construction service across Corralitos, with crews who understand how these paver and wall systems actually perform on steep, clay-rich mountain lots. We are not a Unilock manufacturer affiliate or authorized dealer. We are a general contractor with hands-on experience installing and repairing Unilock product lines under the specific conditions Corralitos throws at hardscape: wildfire code requirements, post-CZU water tank placement, and drainage that fails fast when it is not engineered for winter rain. Call (866) 505-5254 to schedule a free estimate.
Why Corralitos Residents Choose Us for Unilock Service
Unilock makes a solid paver. But the paver is only as good as the base under it, and in Corralitos the base is usually the problem. Clay-rich soil expands and contracts through wet winters and dry summers. Steep grades shed water in sheets. A paver driveway that is flat and true in a Watsonville subdivision needs an entirely different foundation here. That is what we plan for from the first site visit. Noel Cabrera, our owner, grew up working on fog-weathered Daly City homes and trained in construction technology at City College of San Francisco before spending years on residential jobs across San Mateo County. When we quote Unilock work in Corralitos, the base, drainage, and reinforcement are always part of the conversation, because skipping them is how any hardscape fails in this terrain. We are a full-scope general contractor, so the same crew can handle the paver patio, the retaining wall, the home addition, and the roof over it. One contractor, every phase. For broader Unilock sales & service questions, we have the product range and the installation record to back up what we quote.

Common Unilock Construction Problems We Solve in Corralitos
- Paver shifting and joint sand loss from clay heave. Corralitos clay swells when wet and shrinks when dry, which works Unilock pavers apart over a few seasons. We see driveways where the Brussels Block pattern has opened up an inch at the joints. The fix is not just more sand; it is addressing the base and, where needed, adding a permeable joint system that moves with the soil instead of cracking against it.
- Tilting and bulging Unilock walls from poor drainage. Winter rain on a steep Corralitos slope saturates the backfill behind a wall and pushes it forward. We have seen Series 3000 retaining walls leaning 6 degrees within three winters. The repair means pulling the wall, regrading, and installing proper drainage aggregate and pipe before anything goes back in place.
- Scorched or degraded paver finish near wildfire-prone edges. After the 2020 CZU Lightning Complex fire, we started paying closer attention to exposed hardscape in the wildland-urban interface. Embers can scorch and dull Unilock surface finishes, especially on patios backed by chaparral. We recommend fire-rated assemblies and, where the budget allows, pavers with a finish that tolerates heat better.
- Retaining wall failure on slopes without geogrid reinforcement. This is the one we see most from DIY installs and contractors who mostly work flat ground. A 4-foot Unilock wall on a 30-degree slope holds a lot more lateral pressure than the same wall on flat ground. Without geogrid layers tied into the fill, the wall eventually bulges or kicks out at the base. We rebuild these with proper reinforcement every year in Corralitos.
- Base material erosion under Unilock patios from runoff. Steep lots shed water fast. If the patio edge does not have a swale or other diversion, the water scours the crushed rock base out from under the pavers. The paver never failed. The base left. We address the drainage first, then reset the pavers.
Unilock Service in Corralitos: What Local Conditions Mean for Your Equipment
Since the 2020 CZU fire, rebuilds in the Corralitos hills face a requirement most contractors in urban counties have never dealt with: dedicated water-supply tanks for firefighting. These tanks have to go somewhere defensible and accessible to engine crews, and that placement reshapes the hardscape around them. A paver driveway that was originally designed as a simple ribbon from the road to the garage now has to accommodate a 5,000-gallon steel tank, a fill port, and a fire-access turnaround, all while grading water away from the foundation. We design Unilock patios and driveways around tank placement and fire-access of requirements rather than treating the tank as an afterthought. On a steep lot off Browns Valley Road, we rebuilt a Unilock Brussels Block driveway that had settled from clay soil and poor drainage. After regrading and installing a geogrid-reinforced base, we reinstalled the pavers with a permeable joint system and added a swale to divert runoff, meeting both county fire-access and erosion-control requirements. This is not standard hardscape planning. It is Corralitos planning. For a look at how we apply this same thinking elsewhere in the mountains, see our Corralitos service area coverage.
Unilock Models & Products We Service in Corralitos
We work with the Unilock product lines most common in Corralitos: Brussels Block for driveways and walkways, Beacon Hill for patio surfaces with a tumbled, relaxed finish, Series 3000 for larger retaining walls and seat walls, and Olde Quarry for a weathered stone look. Tell me what the house needs, not what you think it needs, then we will figure out the right fix. For replacements, we source genuine Unilock pavers so the color and dimensions match the original installation. On base and drainage materials, we use aftermarket aggregates selected for Corralitos’ clay and slope conditions, not whatever is cheapest at the yard. We keep common Brussels Block and Olde Quarry sizes in regional inventory, which shortens turnaround for Corralitos jobs by a few days compared to special ordering.

AfterUnilock Service Pricing in Corralitos
Unilock paver work in Corralitos prices differently than the same project on flat ground. The cost driver is almost always the base, not the paver. Steep slopes need more excavation, more geogrid, more drainage infrastructure, and sometimes concrete collar footings the plans did not originally include. Fire-access requirements around a water tank can add square footage and grading work as well.
| Service | Typical Range in Corralitos |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |

FAQs – Unilock Construction in Corralitos
Yes. Unilock concrete pavers are non-combustible, which matters when the county requires a non-flammable zone immediately around a structure. The paver itself is fine. What gets you into trouble is the planting and mulch right up against the edge. We install pavers with the clearance and drainage details that satisfy Corralitos’ WUI setback rules, and we offer Freedom Unilock service throughout the region. Call (866) 505-5254 and we can tell you what applies to your lot.
We treat the geogrid and drainage as the primary system, not an upgrade. On Corralitos slopes over 15 percent, we build retaining sections in stages, backfill in lifts, and tie everything together with geogrid anchored into the slope. The pavers go on last. The wall has to hold before the first block is set.
Two things matter here more than anywhere else: joint sand and drainage. Wet winters wash fines out of joints, and clay movement opens them further. We recommend checking joints each fall and addressing any low spots before the rains arrive. Keep drainage swales clear. A paver patio that drains well will look nearly the same in ten years, whether it’s in Corralitos or you need Unilock repair in Interlaken.
Localized paver reset work typically falls between $1,500 and $4,000 depending on the area affected. A full rebuild with base and drainage work starts around $7,000 and goes up from there on steep lots. The exact number depends on what we find under the surface. Call (866) 505-5254 for an exact quote, estimates are free.
Yes. For walls near structures in Corralitos, we install Unilock Series 3000 systems with engineered drainage and non-combustible backfill detail where the county requires it. We pull permits and schedule inspections so the wall is documented, not just built. That paperwork matters for insurance and resale in this area.
We design for that explicitly. The tank needs a level, stable pad, fire crew access, and separation from the structure. The driveway or patio around it has to account for overflow drainage and fill-port access. We plan Unilock hardscape around the tank before the first paver is ordered. Call (866) 505-5254 and we will walk your site with the tank location in mind.
