Unilock Construction in Pacifica, CA | San Bruno Construction
We install and repair Unilock paver systems across Pacifica, from Brussels Block patios on the west side of Highway 1 to Pisa2 retaining walls holding back clay hillsides. As a Pacifica General Contractor, we handle every aspect of the job. We’re an independent Unilock service provider, not an authorized dealer, which means our recommendations come from watching these pavers perform in Pacifica’s salt fog and winter rain, not from a manufacturer playbook. If your patio is heaving, your wall is leaning, or your joints keep washing out every rainy season, call (866) 472-1908 for a free estimate.
Why Pacifica Residents Choose Us for Unilock Service
Most hardscape crews in Pacifica know how to lay pavers. Far fewer understand what happens to a Unilock installation three winters later, when the marine layer has been feeding moisture into the joints daily and the clay subgrade has shifted three separate times. Noel Carvalho, owner of San Bruno Construction, grew up in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and understand load paths before touching a tool. We also provide Unilock service in San Bruno. That background matters on Pacifica hillsides where a paver patio is as much a drainage project as a paving one. We’ve been running residential projects across San Mateo County for over two decades, and we approach every Unilock job by asking what the water is going to do first. That’s why Pacifica homeowners call us when other patios fail.
Good construction doesn’t announce itself; it just works, year after year.

Common Unilock Construction Problems We Solve in Pacifica
- Efflorescence and salt-film bloom on Brussels Block and Beacon Hill surfaces. The white hazy staining on pavers that sit in fog-belt shade looks like failed paving, but it’s usually a moisture and cleaning issue. West-facing Pacifica patios that never fully dry develop this constantly. We clean and reseal, but we also address the drainage that keeps the pavers wet.
- Polymeric sand joint loss and paver movement on slopes. Heavy winter rain sheet-flows across Pacifica’s clay-heavy hillside soils and undermines paver bases that weren’t over-excavated and drained. Joints wash out, sand disappears, units shift. We reset the base, add drainage, and re-sand with a coastal-grade polymeric product.
- Corroded wall fasteners and geogrid pull-out on Pisa2 retaining walls. Onshore salt air eats galvanized connections, especially on west-facing bluff-top terraces above the ocean. When grid connections fail, the wall face starts leaning. We rebuild the connection with marine-grade materials.
- Frost-heave-style lippage and edge spalling. Pacifica’s coastal soil shifts seasonally. Pavers laid too tight to a fixed concrete edge crack and chip. We recommend expansion joints that let the pavement move without failing.
- Pooling water against foundations due to bad subgrade drainage. In our experience across Pacifica, most paver failures trace back to one decision: setting units on native clay with no drainage outlet. We fix that by over-excavating, adding a drained aggregate base with geogrid, and re-installing so winter rain sheds instead of pools.
Unilock Service in Pacifica: What Local Conditions Mean for Your Equipment
The fog belt rot pattern is real, and it affects hardscape as much as framing. Houses on the west side of Highway 1 facing the ocean sit in relentless damp salt air that never lets wood, concrete, or paver joints fully dry. A Brussels Block patio on a bluff-side split-level in Pacifica’s Fairway Park can develop joint loss and surface bloom within a few winters. A few blocks inland, east of the highway, the same installation stays tight for a decade longer. That micro-climate divide drives how we spec base aggregate, which joint sand we use, and whether we recommend permeable pavers over standard units. On a bluff-side split-level off the west side of Highway 1, we pulled up a heaved Brussels Block patio where the original installer had set pavers on native clay with no drainage outlet. We over-excavated, added a drained aggregate base with geogrid, reset the units, and re-sanded the joints. The patio now sheds winter rain instead of pooling it against the foundation. That’s the difference local knowledge makes, and it’s why we treat every Pacifica Unilock job as a drainage project first.
Unilock Models & Products We Service in Pacifica
We install and repair Unilock Brussels Block, Beacon Hill Flagstone, the Pisa2 retaining wall system, and the permeable Treo and Ecovia lines for drainage-driven hardscape. We source genuine Unilock units and matching accessories so color, thickness, and interlock geometry stay consistent. Where aftermarket materials outperform the OEM spec for coastal conditions, we use them: quality geogrid, marine-grade fasteners, and polymeric sand rated for wet, salt-heavy environments. We keep common Brussels Block and Pisa2 components stocked locally in Pacifica so repairs don’t wait on a distributor across the Bay.

The biggest cost driver on a Pacifica hillside is subgrade work: over-excavation, drainage, and geogrid. Cutting that corner is how patios fail within three fog-belt winters. A free estimate includes walking the grade, checking for drainage patterns near the foundation, and flagging any Coastal Commission trigger before you spend a dollar. Call (866) 472-1908 to schedule yours.

FAQs – Unilock Construction in Pacifica
It depends on your exact lot and what you’re replacing or adding. Projects that touch grade on Pacifica’s coastal bluffs and clay hillsides can trigger California Coastal Commission review plus slope-stability and drainage scrutiny. A patio or driveway that expands impervious surface is more likely to require a permit than a like-for-like replacement. We evaluate this at the free estimate and tell you honestly whether you’ll need geotechnical input, because nobody wants a stop-work order on a finished patio. Call (866) 472-1908 and we’ll walk your property before you commit.
The white haze is efflorescence, a mineral bloom from moisture migrating through the concrete paver and evaporating at the surface. In Pacifica, the constant marine layer keeps pavers damp and makes the bloom persistent. Cleaning and sealing helps, but the real fix is drainage: if water pools under the units, the bloom comes back. We can assess whether the base is holding water and correct it. Call (866) 472-1908 for a look at your patio.
A Pisa2 wall holds fine on clay if the design accounts for hydrostatic pressure and slope movement. The failures we see on Pacifica hillsides come from three shortcuts: no drainage column behind the wall, undersized geogrid or short grid lengths, and galvanized fasteners that corrode in salt air. Build it with the right geogrid depth, a clean aggregate drainage zone, and marine-grade connections, and a Pisa2 wall lasts decades here. We’ve rebuilt enough failed walls to know exactly what the original installer skipped.
Stop the water before it moves through the joints. On Pacifica slopes, that means over-excavating the clay, installing a drained aggregate base with proper slope, and using a polymeric sand rated for wet coastal conditions. Re-sanding alone won’t fix an undrained base. We can assess your existing base and tell you whether a re-sand is enough or whether the subgrade needs work. Call (866) 472-1908 and we’ll check the water flow on your property.
Sealing buys you time but doesn’t fix structural problems. If your Pacifica driveway has sunken spots, spreading joints, or water pooling against the garage slab, the base is failing from coastal moisture and clay movement. Sealing locks in the deterioration. Replacement with a properly drained Unilock base costs more up front but holds up for decades. Sealing runs $250 to $700; replacement runs $5,000 to $14,000. Call (866) 472-1908 for an exact quote based on your driveway’s condition.
