Unilock Construction in Loyola, CA | San Mateo Construction
We install, repair, and replace Unilock pavers and retaining walls throughout Loyola, CA. The one thing that sets our Unilock work here apart is how we plan for what’s underground: protected heritage oak root zones, expansive clay soils, and Los Altos planning review. That’s not a generic talking point, it’s the reality of every paver driveway and patio in the 94024 ZIP code. Call (855) 901-7266 for a free estimate and we’ll tell you honestly what your project needs.
Why Loyola Residents Choose Us for Unilock Service
We’ve installed Unilock in Los Altos on Loyola’s mid-century ranch lots and hillside-adjacent properties for years. We know how Brussels Block settles under winter rain, how Beacon Hill wall blocks react to poor hillside drainage, and how Town Hall pavers look after three seasons under a shaded oak canopy. That material-level familiarity means we don’t guess at fixes. We walk the site, look at the grade, check the tree canopy, and then tell you what’s actually going on.
We’re independent Unilock installers, not authorized by Unilock. That matters because we can repair or replace any failed section without pushing a full teardown when a localized fix will hold. Noel Carrington grew up pouring concrete footings in San Mateo County, and after three decades of residential work he still believes the same thing: the base matters more than the paver. If your Unilock patio is failing in Loyola, it’s almost never the paver. It’s what’s underneath it.

Common Unilock Construction Problems We Solve in Loyola
- Brussels Block settling and shifting on driveways. Loyola’s expansive clay soil swells in winter rains and shrinks in dry summers. Without a geotextile separation layer, the base material erodes into the subgrade and pavers sink. We see this on driveways throughout 94024, particularly those built 15 – 20 years ago when base prep standards were looser.
- Beacon Hill wall efflorescence and face spalling. On hillside properties, water collects behind retaining walls during heavy storms. If the wall lacks proper drainage stone and weep holes, that trapped water pushes through the block face, leaving chalky white mineral deposits and eventually flaking the block surface.
- Town Hall paver moss and algae buildup. Loyola’s shaded, tree-lined streets and damp winters create ideal conditions for moss growth on patios. Town Hall’s textured surface is especially vulnerable. We remove it with targeted cleaning and address the drainage or shade issue so it doesn’t return the following spring.
- SiennaStone wall cracking from root intrusion. Loyola’s protected oaks send roots outward aggressively. When roots reach a compacted base, they dislodge it, and the wall above cracks or leans. This is one of the most common wall failures we correct on wooded lots.
- Pooling water against garages and foundations. A poorly graded paver driveway sends runoff toward the structure instead of away from it. Let that go for a winter or two and you’ll be dealing with foundation dampness, not just paver issues.
Unilock Service in Loyola: What Local Conditions Mean for Your Equipment
Loyola is one of the wealthiest, most permit-heavy residential enclaves in Santa Clara County, and we also provide Unilock service in Mountain View. Nearly every construction project here runs through Los Altos planning review, with strict single-story and floor-area-ratio limits, and that scrutiny extends to hardscape. On the tree-lined streets of 94024, a single protected heritage oak can stall or redesign an entire remodel. Arborist reports and tree-protection plans are standard line items on almost every Loyola job.
Here’s what that means for Unilock owners specifically. A standard concrete driveway would be rejected outright if it encroaches on a protected root zone. Unilock’s permeable paver systems, however, give you a code-compliant path forward. Permeable pavers allow water and air to reach the root system, which satisfies arborist requirements that impermeable hardscape cannot. We also use root-friendly base designs like open-graded stone and geogrid reinforcement so the base stays stable even as roots spread underneath. This local knowledge separates us from a contractor who treats Loyola like any other Peninsula suburb. If you’re planning a paver driveway or patio near a heritage oak, call (855) 901-7266 before any concrete gets poured.
Unilock Models & Products We Service in Loyola
We work with the full range of Unilock residential product lines, including Brussels Block, Beacon Hill, Town Hall, and SiennaStone. We source genuine Unilock pavers and wall blocks for repairs and new installations to ensure color and dimensional consistency across the project. For base materials and jointing compounds, we use high-quality aftermarket products that meet or exceed Unilock specifications, including permeable base stone and polymeric sands rated for heavier traffic. If you have an existing Unilock patio or wall that’s failing, we assess whether a localized repair or full replacement makes more financial sense. We’ll tell you if you can save the section and match the color, or if the base is too far gone and needs redoing. For homeowners browsing our broader work, we offer Unilock sales & service across the Peninsula with the same independent, material-specific approach.

AfterUnilock Service Pricing in Loyola
Here’s what Unilock hardscape work costs in the Loyola / Los Altos market, with Unilock service in Los Altos Hills priced similarly. These ranges reflect local permitting requirements, tree-protection compliance, and material costs for genuine Unilock products, so they’ll differ from looser estimates you might see elsewhere.
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
What drives the price? The size of the paver area, whether we’re excavating an old failed base, whether an arborist report and tree-protection plan are required, and the Unilock product line you select. Town Hall costs more than Brussels Block, for example, and a hillside retaining wall with drainage corrections costs more than a flat patio. Your free estimate includes a site walk, a written line-item quote, and a clear answer on whether you need a permit. Call (855) 901-7266 for an exact number.

FAQs – Unilock Construction in Loyola
Yes, in most cases. A permeable Unilock paver system with an open-graded base is one of the few hardscape options that Los Altos planning and arborist consultants will typically approve near a protected oak root zone. You’ll still need an arborist report and a tree-protection plan. Call (855) 901-7266 and we’ll walk the site and tell you whether your specific tree falls under the protection ordinance.
Mostly it’s drainage, not the block. When water pools behind a retaining wall on a hillside lot and can’t escape through weep holes or a drainage layer, it pushes through the block face and causes efflorescence, spalling, and eventual structural movement. We correct that by rebuilding the wall with proper drainage stone, filter fabric, and weep holes. Want to know what’s going on with your wall? Call us for a free inspection.
Any hardscape project in Loyola that involves tree protection, grading changes, or significant impervious surface goes through Los Altos planning review. That typically adds two to six weeks to the timeline, depending on whether an arborist report is needed. We handle the permit package as part of the job, so you don’t need to chase down paperwork. Call (855) 901-7266 for a realistic start date based on your specific property.
We recommend a paver with a smoother surface profile under heavy canopy. Town Hall looks right in shaded settings but its texture invites moss and algae in Loyola’s damp winters. A smoother line like Brussels Block or a sealed finish is easier to keep clean. The real fix is drainage and airflow, not just product selection.
We do both, and we’ll be straight with you about which path makes sense. If the base is intact and it’s localized damage, we repair and match the color as closely as the product line allows. If the base has failed, repairs won’t hold and we’ll say so. Call (855) 901-7266 and we’ll give you an honest assessment.

On a tree-lined street in the Loyola neighborhood, we replaced a failing Brussels Block driveway where winter rains had caused severe settling and pooling against the garage. After an arborist confirmed the protected oak’s root zone, we installed a permeable Unilock base with a geogrid and re-laid the Brussels Block in a herringbone pattern, solving the drainage issue without harming the tree. The homeowner now has a stable, root-safe driveway that meets Los Altos planning requirements.
That’s the level of local detail we bring to every Unilock job in Loyola. Tell us what you actually need, and we’ll figure out the right way to build it. Call (855) 901-7266 to schedule your free estimate.
