Unilock Construction in Redwood City, CA
We install, repair, and re-lay Unilock paver systems across Redwood City Home Remodeling areas, and we’ve been doing it long enough to know the difference between a paver job that survives ten Peninsula winters and one that starts settling by the second. What makes our Unilock work different here comes down to one thing: we understand what mature redwood roots and Redwood City’s clay soils do to a paver base, and we build for it from day one. You’re not getting a manufacturer’s rep. You’re getting a crew that has dug into Redwood City’s specific ground conditions and learned what holds up.
Call (877) 373-9230 for Unilock service in Redwood City. Written estimates are free, and we’ll walk your project with you before we quote a number.
Why Redwood City Residents Choose Us for Unilock Service
We’re a licensed Redwood City General Contractor with a hardscape division that has installed Unilock products across the Peninsula for years. But here’s the thing most homeowners don’t find out until after a job goes sideways: the paver is rarely the problem. The base is. And base design in Redwood City is different from base design in San Carlos or Menlo Park, because your lots are tighter and your trees are bigger.
Noel Cardenas grew up in Garden Grove and came up through the construction trades at Santiago Canyon College before spending years running projects in every phase of residential builds. When he talks about a Redwood City paver job, he’s thinking about stormwater, root intrusion, and whether the edge restraint will still be holding in ten years. That’s the standard we bring to every Unilock installation we touch.
We stay brand-current, too. Our team has worked with Unilock products long enough to know which lines hold up under vehicle loads and which ones belong on a patio, not a driveway apron.

Common Unilock Construction Problems We Solve in Redwood City
- Base settlement on clay. Redwood City’s soil runs heavy with clay near the Bay flats, and clay expands and contracts with moisture. When a base is built too thin or without proper compaction, pavers sink within two or three years, especially where downspouts and winter runoff saturate the same spots. We rebuild the base correctly and re-lay the pavers so they stay put.
- Redwood root lift in side yards. On narrow lots with 6 – 8 ft setbacks, paver walkways often run directly over root zones. Mature redwoods push roots toward any available moisture, and those roots will lift a base and shift pavers. We hand-dig around roots and install barriers before rebuilding.
- Efflorescence on light pavers. Dry Redwood City summers plus irrigation overspray plus dust equals a white, chalky bloom on light-colored Unilock pavers. It’s not a product defect. It’s mineral salts wicking to the surface. We clean it and, more importantly, adjust the drainage and irrigation pattern so it doesn’t come back.
- ArmorTec face spalling at driveway aprons. The edges of a paver driveway take the most abuse from tires, and Redwood City’s occasional freeze-thaw nights can chip the face of pavers at street transitions. We replace damaged units and reinforce the edge restraint so the next round of rain doesn’t make it worse.
- Joint sand washout. Narrow side runs and sloped driveways channel water fast during rainy season. When joint sand washes out, pavers shift and crack. We use polymeric sand where it suits the drainage, and we grade so water moves away from the paver field entirely.
Unilock Service in Redwood City: What Local Conditions Mean for Your Project
Here’s the detail most paver contractors won’t tell you about working in Redwood City: the 6 – 8 ft side setbacks in the historic downtown neighborhoods, around ZIPs 94061 and 94063, mean your paver walkway isn’t running through open lawn. It’s running right along the root zone of mature redwoods that were planted when these bungalows went up in the 1920s and 1930s. A redwood root system can extend well past the canopy, and it will find the moisture trapped under a paver base. Crews in San Carlos or West Menlo Park rarely deal with this, because their lots are wider and their trees are further from the structure. In Redwood City, we hand-dig the base when roots are present, lay a root barrier, and use a heavier geotextile than we’d spec on an open lot. That one difference is often the difference between a walkway that stays flat and one that looks like a wave pool after two years. We’ve seen it enough times to know which one you’re going to get if you skip the root work.
This is why our Redwood City service area work starts with a site walk, not a phone estimate. We need to see the trees, the drainage, and the grade before we quote.
Unilock Models & Products We Service in Redwood City
We install and repair the Woodside Unilock service lines that make sense for Redwood City lots. Unilock Brussels Block remains the workhorse for driveways and parking pads, especially where a classic cobblestone look fits the neighborhood. Unilock Cambridge Pavingstones with ArmorTec hold up well on high-traffic walkways and pool surrounds. Unilock Beacon Hill Flagstone gives a flagstone feel without the cost of natural stone and works nicely on Redwood City patios. For retaining walls and planter edges, we spec Unilock Estate Wall products.
On parts, we use Unilock’s OEM edge restraints, joint sands, and polymeric sands where specified. But we don’t hesitate to substitute aftermarket base materials, geotextiles, or drainage components when Redwood City’s soil conditions call for a heavier build-up. The paver is the face. The base is what survives.

A driveway on a flat lot with no trees is a very different number from a driveway squeezed between a bungalow and a mature redwood with a 6 ft setback.

FAQs – Unilock Construction in Redwood City
Yes, if the crew knows what they’re doing. We hand-dig the base around significant roots, use a root barrier to redirect future growth, and avoid cutting any structural root larger than 2 inches in diameter. The tree stays healthy; the pavers stay level. We’ve done exactly this on several 1940s-era Redwood City bungalow jobs.
Rain between November and March can delay base compaction and joint sand work. We still install through the rainy season, but we schedule around heavy downpours and cover exposed work with tarps. If you want your patio or driveway ready by spring, late summer and early fall are the best windows to start. Call (877) 373-9230 and we’ll give you an honest timeline for your specific project.
Unilock Brussels Block is our most common choice for Redwood City driveways on narrow lots. The unit size handles vehicle loads well, and the pattern holds together even when the driveway has to make a tight transition into a 6 ft side setback.
Efflorescence appears when water wicks mineral salts to the surface of the paver, then evaporates in the dry summer air. In Redwood City, irrigation overspray and dust accelerate it. It’s cosmetic and cleanable, and we also address the water source so it doesn’t come back every August.
When failure is isolated, we repair the section and reinforce that area’s base and edge restraint. When the base is compromised across the whole field, we recommend a full re-lay, because patching a failing base is just paying twice. We’ll tell you which one you’re looking at, and we’ll quote both. Call (877) 373-9230 for a free assessment.
