Unilock Construction in Ben Lomond, CA | San Bruno Construction
We install and repair Unilock paver patios, driveways, and retaining walls across Ben Lomond, CA (95005), and also offer Unilock in Lompico. San Bruno Construction is an independent contractor, not a Unilock dealer or authorized affiliate. The one thing that makes our Unilock work different in Ben Lomond is that we design every base and edge for redwood root zones, saturated hillside soils, and Santa Cruz County permit scrutiny, not for a flat suburban lot. Call (866) 472-1908 for a free estimate on your Ben Lomond paver project.
Why Ben Lomond Residents Choose Us for Unilock Service
Unilock makes solid pavers, but a paver is only as good as what it sits on. Ben Lomond lots are steep, shaded, and full of protected coast redwood roots. That combination breaks flat-lot assumptions fast. Our crew, led by Noel Carvalho, has spent over two decades building and repairing hardscape on hillside and tree-canopied sites across the Bay Area and the Santa Cruz Mountains. Noel studied construction technology at Skyline College in San Bruno, where he learned to read plans and understand load paths before a single tool comes out of the truck. We bring that same thinking to every Unilock install in Ben Lomond and our Brookdale Unilock service: dig shallow where roots demand it, drain water off the downhill edge, and restrain the borders so the field stays flat. We use Unilock’s own matching units, U-Cara components, and edge restraints instead of mixing in generic pavers that won’t dimension or color match. Call us at (866) 472-1908 and we’ll walk your property the way a Ben Lomond contractor should.

Common Unilock Construction Problems We Solve in Ben Lomond
- Root-zone heave. Pavers laid over a base cut too close to protected redwood roots lift and rack out of plane in a season or two. We repair these by re-setting the field on a shallow, free-draining base that respects the root zone instead of fighting it.
- Winter-saturated base failure. Heavy mountain rain pushes water under a shallow, poorly drained base, so pavers pump and settle. This is common on Ben Lomond’s hillside lots and rare on flat valley ground. We rebuild with open-graded aggregate and proper drainage paths.
- Polymeric sand washout. Redwood duff, fog, and winter rain keep joints wet, so sand erodes, weeds seed in, and the field loses interlock. We clean and re-sand joints in a genuine dry window, not on a damp 55-degree day when the sand won’t cure.
- Edge and retaining course failure. On stepped or sloped Ben Lomond installations, unrestrained edges fail under saturated soil and slope creep. We install engineered edge restraint rated for the slope, not a plastic strip meant for a flat patio.
- Paver cracking over old deck footings. Many Ben Lomond patios replace rotted decks, and the old footings stay in the ground. We identify and remove or bridge them before the pavers go down, so you don’t get a cracked field two years after a teardown.
Unilock Service in Ben Lomond: What Local Conditions Mean for Your Equipment
Much of Ben Lomond’s buildable ground is constrained by coast redwood root zones and Santa Cruz County tree protections. A paver patio or driveway here can’t just cut grade to a flat plane. The base often has to be designed as a raised, free-draining, root-bridging structure that keeps excavation shallow, which changes paver spec, base depth, and edge restraint versus a normal flat-lot install. On a recent project off Highway 9 in Ben Lomond, a homeowner wanted a Brussels Block patio where an old deck had rotted out under tree litter and winter fog. Cutting grade for a conventional base would have sliced into a protected redwood root zone, so our crew built it as a shallow, raised, free-draining base with open-graded aggregate and engineered edge restraint, capped with matching Unilock border units and fresh polymeric joint sand set in a genuine dry window. Two wet seasons later the field is still flat and shedding water off the downhill edge instead of pumping. That’s the difference between a Ben Lomond paver design and a generic one.
Unilock Models & Products We Service in Ben Lomond
We install and repair the Unilock lines that actually hold up in the Santa Cruz Mountains. That includes Brussels Block (tumbled concrete paver), Beacon Hill Flagstone (textured slab paver), Townhall (permeable paver), and the U-Cara retaining wall system. We keep matching border and cap units on hand for Ben Lomond repairs, and we order Unilock’s own restraint and edge products when the system calls for them. For repairs, we lift and reset sound units and replace only what’s cracked or heaved. We don’t push a full tear-out when the base is still competent, and we don’t swap in generic pavers that won’t color or dimension match your existing field. If we need to explain your Unilock options before quoting, our team covers Unilock sales & service details on a dedicated page.

FAQs – Unilock Construction in Ben Lomond
Most paver patios in Ben Lomond do not trigger a building permit on their own, but driveways and any work near protected trees or within a creek setback can. Santa Cruz County reviews tree protection and drainage on hillside lots more strictly than flat valley jurisdictions. We check the permit path for your specific parcel before we quote, so there are no stops after the work starts. Call (866) 472-1908 and we’ll assess your site.
Yes, in most Ben Lomond cases. If the base aggregate is still competent and the edges are intact, we lift the affected area, correct the drainage or root issue that caused the settling, and re-set the sound units. We replace only cracked or heaved pavers. A full driveway replacement is only the answer when the base has washed out or root heave has compromised the entire field. Call (866) 472-1908 for a repair assessment.
No. We are an independent contractor that installs Unilock products on Ben Lomond’s steep, tree-canopied lots. We are not authorized or endorsed by Unilock, and we don’t pretend to be. Our credibility comes from knowing which Unilock products survive root zones, winter saturation, and debris loads, and which ones fail here.
Most repair jobs run one to three days, depending on how much base correction is required. We schedule paver sand and joint work around dry windows, which matter more in Ben Lomond than in drier parts of the Bay Area. We’ll give you a firm window once we see the site.
Most Ben Lomond patio repairs fall between $1,200 and $4,500, depending on how many feet of base need re-cutting and whether we’re re-setting a few pavers or an entire field. If the base is still sound, a repair beats a replacement every time. Call (866) 472-1908 for an exact quote, free of charge.
