Unilock Construction in Foster City, CA | San Bruno Construction
We install and repair Unilock paver driveways, patios, and retaining walls throughout Foster City. We’re an independent hardscape and construction crew, not a Unilock dealer or authorized service provider, and we say that plainly because it matters. What makes our Foster City work different is that we treat the base as the real spec: the lagoons, the fill, the water table, and the salt air dictate what we dig, what we lay, and what we specify. If you’re pricing a Unilock paver project in the 94404, call Noel Carvalho and the team at (866) 472-1908 for a free estimate.
Why Foster City Residents Choose Us for Unilock Service
We’ve spent years working on bay-front and lagoon-adjacent properties where ordinary paver specs fail. Foster City homeowners call us after another crew laid pavers on four inches of sand and a prayer, and the field started pumping water through the joints within one rainy season. We understand Unilock’s product line deeply, including Brussels Block, Cambridge Pavingstones with ArmorTec, Estate Wall, and Beacon Hill Flagstone, but we understand Foster City’s ground even better. Noel Carvalho grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, learning to read plans and think through load paths before a single tool comes out of the truck. His crew has run hardscape projects across San Mateo County, including lagoon-front homes in Foster City where digging meant dewatering before compacting. We use genuine Unilock units and their edge-restraint systems, but we’ll tell you when the existing pavers are fine and the base beneath them is the actual problem. Our Unilock sales & service work spans the full scope: paver driveways, paver patios, concrete driveways, and retaining walls.

Common Unilock Construction Problems We Solve in Foster City
- Polymeric sand washing out after winter rain. Foster City’s flat fill lots hold water, and when the base never fully drains, the joint sand pumps out and re-settles, leaving soft joints and wobbly pavers. We re-spec the base and drainage, then re-sand with a mix matched to the traffic load.
- Salt-air corrosion of steel edging and fasteners. The Bay’s salt-laden air eats plain steel edging stakes and border fasteners years before the Unilock pavers show wear. We use corrosion-resistant edge restraint and check existing borders for stake rot on every repair call in Foster City.
- Differential settlement and lippage. It’s common for half a patio to sit on engineered fill and half on an old slab or footing, creating trip edges and ponding across a Unilock paver field. We re-level the affected section and re-compact, rather than tearing out sound pavers.
- Efflorescence on light-colored pavers. High groundwater wicks moisture up through an open-graded base that wasn’t separated with filter fabric, leaving white mineral staining on Unilock faces. We correct the separator and often save the pavers.
- Lagoon-side excavation hitting water. Digging footings or base rock near a lagoon channel in Foster City often hits water before you reach grade. We plan for dewatering from the start, which changes the schedule and the spec, but avoids a half-excavated mess.
Unilock Service in Foster City: What Local Conditions Mean for Your Equipment
Foster City is almost entirely built on engineered fill and bay marshland. Dig anywhere near a lagoon channel and you’ll likely hit water before you hit stable bearing soil. A paver driveway or patio excavated in a lagoon-adjacent neighborhood, like the homes along the channels off Edgewater Boulevard, is often a dewatering job before it is ever a paving job. That means submersible pumps, silt control, and a base built up in lifts with heavy compaction, because if the base doesn’t drain and settle evenly, the Unilock field above it will move. For parcels fronting the lagoons, the Bay Conservation and Development Commission’s shoreline rules can add a permit layer the inland tracts of Foster City and Highlands-Baywood Park Unilock service areas never touch. This is why our quotes for lagoon-side Unilock work are line-itemed honestly: the pavers cost the same as anywhere else, but the ground preparation here is a different animal, and anyone who prices a Foster City lagoon project without accounting for water and BCDC review hasn’t done it before. Good construction doesn’t announce itself, it just works, year after year.
Unilock Models & Products We Service in Foster City
We install and service Unilock Brussels Block, Cambridge Pavingstones with ArmorTec, Estate Wall, and Beacon Hill Flagstone. We stock common edge restraint and joint sand in our trucks and can typically order matching units fast for Foster City repairs. When it comes to parts, we use genuine Unilock units and their matching edge-restraint and joint-sand systems, but we treat the base as the real spec. If an existing paver field is sound but settling, we’d rather re-lay those same Unilock pavers on a corrected base than push a full tear-out just to sell product.

FAQs – Unilock Construction in Foster City
Because Foster City sits on engineered bay fill with a high water table, and a paver driveway excavated near a lagoon channel regularly needs dewatering and a deeper, heavier compacted base to prevent pumping and settlement. San Mateo Unilock service sits on more stable ground. Call (866) 472-1908 for a free estimate and we’ll show you exactly where the base costs land on your lot.
It can. If your parcel fronts a lagoon and the work touches the shoreline area, the Bay Conservation and Development Commission’s review process may apply, adding a permit layer inland Foster City parcels never face. We check this early so it doesn’t surprise you mid-project.
They can if the open-graded base isn’t separated with the right filter fabric. High groundwater wicks moisture up through the base, carrying minerals that dry as white staining on light-colored Unilock faces. We correct the separator and re-lay affected pavers so the problem doesn’t return.
Unilock’s concrete pavers themselves are dense and hold up well, but the salt air attacks steel edging stakes and fasteners first, so we spec corrosion-resistant edge restraint for any Foster City border. The paver faces rarely fail; the metal holding the field together does.
Mostly we re-level. If the Unilock units are intact, we lift the settled area, correct the base and filter fabric, and re-lay the same pavers on compacted fill. Full replacement only makes sense when the pavers themselves are cracked or heavily worn. Call (866) 472-1908 for an exact assessment, the quote is free.
