Unilock Construction in Redwood Shores, CA | Toolbox Contractors
Unilock paver and wall work in Redwood Shores has to account for something most hardscape crews never deal with: this city sits on filled bay marshland, and that changes how every base gets built. We’re Toolbox Contractors, an independent Unilock installer serving Redwood Shores with hardscape work that holds up to bay mud, salt air, and winter rains. If you’re planning a paver driveway, patio, or retaining wall here, call (855) 382-3257 for a free estimate. You need a crew that knows what’s under your pavers, not just what goes on top.
Why Redwood Shores Residents Choose Us for Unilock Service
Norm Castellano grew up around half-finished houses and learned early that the foundation work nobody sees is what determines whether a job lasts. That lesson applies double in Redwood Shores, where the “foundation” under a paver patio might be twelve inches of fill over bay mud. Our crews have laid Unilock in Redwood Shores using Brussels Block, Beacon Hill, Rivenstone, and Bristol Valley for years, and we know which products hold up on lagoon-front properties and which need extra base prep before the first paver drops.
We’re an independent contractor, not a Unilock dealer or authorized installer. That means we give you honest repair-versus-replace advice without any brand loyalty getting in the way. When a paver system fails here, the cause is almost always below the surface: inadequate compaction, no dewatering plan, or base material that was never over-excavated. We fix all three. And since we also serve as a Redwood Shores General Contractor who frames, roofs, and remodels, we see the whole property, not just the hardscape. That’s useful when your patio drains toward your foundation or your retaining wall is pushing against a fence post.

Common Unilock Construction Problems We Solve in Redwood Shores
- Efflorescence and salt staining on Brussels Block pavers. North-facing patios near the lagoons get almost no winter sun, so moisture lingers and bay salt wicks up through the pavers, leaving white crusty deposits. Washing alone doesn’t fix it. We treat the salt source and adjust base drainage so it stops returning.
- Settlement and uneven joints in paver driveways. Bay mud compresses unevenly, especially near the canals. We see Brussels Block driveways with a two-inch dip after three or four years because the original installer compacted over native soil instead of over-excavating. The fix is rebuilding the base, not re-screeding sand.
- Joint erosion from salt-laden fog. Polymeric sand breaks down faster in Redwood Shores air than it does in Belmont or Foster City. The salt weakens the polymer binder, joints erode, and pavers start rocking. We spec a higher-grade polymeric sand with better salt resistance and re-set the edge restraints.
- Frost heave and drainage failures in retaining walls. High groundwater from the bay pushes against Unilock wall blocks, and if weep holes are undersized or backfill was skipped, hydrostatic pressure does the rest. We rebuild with proper drainage stone, geotextile, and corrosion-resistant fasteners.
- Standing water on low-slope paver patios. Redwood Shores lots are flat by design, which means surface drainage has to be engineered into the patio pitch. When it isn’t, winter rains pool against stucco and slab edges. We re-grade and re-lay with the right slope for this terrain.
Unilock Service in Redwood Shores: What Local Conditions Mean for Your Equipment
Redwood Shores is a master-planned community built on filled bay marshland, and that fact governs virtually every hardscape decision here. The Bay Conservation and Development Commission, along with city engineered-fill rules, means even a small paver patio off your back door may require dewatering before excavation and a heavily over-excavated or pile-supported base. Contractors from solid-ground Peninsula cities like Unilock in San Mateo routinely skip this step because they’ve never needed it. In Redwood Shores, skipping it means your Unilock patio settles within two years.
On a lagoon-front home off Shell Parkway, we replaced a settled Brussels Block driveway that had rocked visibly over bay mud. After dewatering and over-excavating 18 inches, we compacted in lifts and re-laid the pavers with new edge restraints and polymeric sand rated for salt exposure. That driveway has stayed level through two wet winters. We can’t promise every job needs 18 inches, but we can promise we won’t guess. Tell me what you’ve got and I’ll tell you what it actually needs.
Unilock Models & Products We Service in Redwood Shores
We install and repair the Unilock lines most common in Redwood Shores: Brussels Block for driveways and patio floors, Beacon Hill for a more finished flagstone look, Rivenstone for larger-format surfaces, and Bristol Valley for retaining walls and seat walls. For repairs, we source OEM Unilock pavers and wall units so color and dimension match what’s already down. Where OEM is appropriate, we use it. Where a local job calls for something better, like upgraded polymeric sand or geotextile rated for bay conditions, we say so and spec accordingly. Our Unilock sales & service work covers everything from single-paver replacement to full base rebuilds.

FAQs – Unilock Construction in Redwood Shores
Yes. Redwood Shores sits on engineered fill over bay mud, so a standard 4-inch compacted base that works in Belmont or Foster City is often inadequate here. Most projects need over-excavation, geotextile, and sometimes dewatering before the base goes in. Call (855) 382-3257 and we’ll tell you what your specific lot requires.
Salt-laden air and persistent winter moisture combine to pull minerals through the paver surface, leaving white deposits. Lagoon-front homes get more of both. The fix involves addressing base drainage and surface moisture, not just cosmetic cleaning. We can assess your wall and recommend the right approach.
Yes, in most cases. We source OEM Brussels Block in your color blend and check batch tones against what’s already installed. Some fading is normal, but we’ll lay out a matching plan before installation so you know what to expect. Your patio addition should look like it was always there. Call (855) 382-3257 for a match-check.
It can, especially if your property falls within BCDC’s bay jurisdiction or near the lagoons. Many small patio projects slide through city review without much friction, but engineered-fill requirements still apply. We’ll tell you during the estimate whether your project needs additional review and handle the paperwork if it does.
We rebuild with proper weep holes, drainage stone backfill, and geotextile separation. In high-groundwater areas of Redwood Shores, the wall’s drainage system matters more than the blocks themselves. If your wall is leaning or bulging, call (855) 382-3257 and we’ll diagnose whether it’s a drainage failure or something deeper.
