Unilock Construction in Belmont, CA | Framework Contractors
We’re Framework Contractors, and we provide our Unilock services across Belmont, CA. We are not Unilock-authorized, and we tell you that straight. What sets our Unilock work here apart is simple: we build bases and drainage for Belmont’s clay hillsides and landslide-prone slopes, because that’s what decides whether a Unilock patio, driveway, or retaining wall actually survives. Call (844) 681-3590 for a free estimate on your Belmont Unilock project.
Why Belmont Residents Choose Us for Unilock Service
We’ve installed Unilock pavers, walls, and steps on Peninsula hillside lots long enough to know exactly how they behave when Belmont’s winter rains saturate the ground and runoff finds every weak spot in the base. Noel Carbajal, our owner, spent his early years watching his uncle patch stucco and reroof porches, and he carried that habit of looking past the surface into every job since. When we take on a San Carlos Unilock service or Belmont project, we look at slope, drainage, and what’s under the paver before we ever set the first unit. That’s why homeowners here call us for repairs other crews won’t touch, and why we’re the crew people call after a wall has started to lean.
We use genuine Unilock units for color and dimensional match on visible faces, and quality aftermarket geogrid, filter fabric, and base aggregate where spec allows. Those hidden components, not the paver itself, decide whether your wall or driveway holds through a Belmont winter. We’d rather explain that before the estimate than after the failure.

Common Unilock Construction Problems We Solve in Belmont
- Efflorescence and salt bloom on Brussels Block and Beacon Hill pavers. Belmont’s clay soils stay wet through the rainy season, and when the base doesn’t drain, moisture wicks up through the paver and leaves that white chalky deposit on the surface. We fix the drainage first, then treat the bloom. If we just cleaned the surface without fixing the base, you’d be calling us back next spring.
- Paver edge settlement and joint sand loss on sloped driveways. The western hillside streets in Belmont are notorious for this. When a base wasn’t over-excavated and separated with geotextile fabric on expansive clay, the edges sink and the joints blow out within a few seasons. We see it constantly. We repair localized settlement and re-sand rather than tear out a sound Unilock field.
- U-Cara and Pisa2 retaining walls tilting or bulging. On hillside lots, a wall without proper geogrid reinforcement and gravel drainage behind it will eventually lean. The soil behind the wall gets heavy with winter rain, hydrostatic pressure builds, and the wall starts to move. We take the wall down, rebuild the drainage, and add the reinforcement that was never there.
- Polymeric joint sand washing out and moss staining on north-facing patios. Belmont’s winter shade and runoff keep north-facing patios damp for months. Cheap joint sand washes out in the first heavy rain, and moss takes hold where the sun never reaches. We re-sand with a proper polymeric product and address the surface grading so water stops pooling.
- Full base failure under a Unilock driveway. Sometimes the paver field looks fine on top but the base has turned to mush underneath. That’s when the driveway ripples or sinks after a heavy rain. We only recommend full replacement when the base has actually failed. If the pavers are sound, we repair what’s underneath and re-lay the same units.
Unilock Service in Belmont: What Local Conditions Mean for Your Equipment
On Belmont’s western hillside streets, even a modest patio or driveway project can trigger a geotechnical review because the lots sit on ancient landslide terrain. That’s not a bureaucratic nuisance; it’s the reality of building on ground that has moved before and will move again. What it means for Unilock owners is that base design and drainage have to be engineered for slope movement, not just laid on compacted dirt the way you might get away with on a flat lot in the flats near El Camino Real. We over-excavate below the clay line, lay geotextile fabric between the native soil and the aggregate, and pitch everything away from the structure. On a hillside lot off the western neighborhoods above El Camino, we tore out a heaved U-Cara retaining wall and a Brussels Block patio where the original base had been laid directly on clay with no drainage, a problem we’ve also solved with San Mateo Unilock service. We over-excavated, added filter fabric and a gravel drainage chimney, set geogrid in the U-Cara courses, and re-laid the Brussels Block on a compacted aggregate base pitched away from the house. After the following winter’s runoff, the wall stayed plumb and the patio drained clean. That’s the difference between a Unilock project that lasts and one that fails in three seasons.
Unilock Models & Products We Service in Belmont
We work with the full range of Unilock product lines common on Belmont properties: Brussels Block, Beacon Hill, Pisa2, and the U-Cara retaining wall system. Each has its own failure habits on clay soil, and we know them all. When a repair calls for replacement units, we source genuine Unilock pavers and blocks so the color and dimensional match stay true on the visible face. For the structural components nobody sees, geogrid, filter fabric, and base aggregate, we use quality aftermarket materials that meet or exceed the spec. That’s what keeps your cost reasonable without cutting the corner that matters.

FAQs – Unilock Construction in Belmont
Yes, but only if the base is built for slope movement. On Belmont’s landslide-terrain lots, we over-excavate past the clay, lay geotextile fabric between native soil and aggregate, and grade the base away from the house. Laid directly on compacted clay, Unilock pavers will heave in a few wet winters. Call (844) 681-3590 for a site assessment and free estimate.
The most common cause in Belmont is missing geogrid reinforcement and poor gravel drainage behind the wall. Water builds up in the clay soil, pressure pushes outward, and the wall blocks tilt. We rebuild U-Cara and Pisa2 walls with proper gravel drainage and geogrid at the right course heights. Call (844) 681-3590 to have us look at the wall before it fails completely.
That’s efflorescence, and in Belmont it usually traces back to wet clay soil under the pavers. Moisture wicks up through the paver, carrying salts that crystallize on the surface. Cleaning the bloom helps temporarily, but the fix is fixing the drainage below the paver field. Call (844) 681-3590 and we’ll diagnose it properly.
Sealing isn’t required for structural reasons, but it helps protect the paver surface from Belmont’s wet winters and reduces moss and staining on shaded driveways. It runs $250 to $700. We’ll tell you honestly whether your driveway would benefit or whether the money’s better spent on drainage. Call (844) 681-3590 for a straight answer.
In Belmont, a paver patio typically runs $3,500 to $11,000, and a paver driveway $7,000 to $18,000. Hillside lots on the western side run higher because of over-excavation and drainage work. Call (844) 681-3590 for an exact quote on your property; estimates are free.
