Why Communications Hill Residents Choose Us for Unilock Service
We’ve worked with Unilock products long enough to know that a Brussels Block driveway behaves differently on a 12% grade than it does on a flat Campbell lot. The manufacturer makes a good paver. The base, the edge restraint, and the drainage plan are what determine whether it stays locked. That’s where our Unilock sales & service work focuses.
Glen Sorrento, our owner, grew up in Foster City watching lagoon-side homes get built and rebuilt. That taught him early that water moves the way it wants to, and anything you build on top of it had better account for that. On Communications Hill, where every street is a terrace and every downhill neighbor inherits the uphill runoff, that lesson applies double. We also bring Unilock in Seven Trees the same water-smart approach. We’re a full-scope general contractor, not a paver-only outfit, so when we install Unilock on a hillside lot we’re also thinking about the roof drainage, the downspouts, and the retaining walls that feed water into the ground beneath your pavers.

Common Unilock Construction Problems We Solve in Communications Hill
- Paver migration and joint sand loss on sloped driveways. Winter storms channel runoff down the terraced streets of Communications Hill, and uphill lot runoff scours the open-graded base under sloped driveways. You’ll see pavers drifting toward the street and joints emptying out within a season or two. We rebuild the base with proper compaction and replace joint sand with Unilock’s own polymeric product.
- Efflorescence on light-colored pavers. Mineral-rich water wicking up through a saturated base leaves white, chalky deposits on Unilock pavers, especially the lighter Elegance and Umbriano lines. This isn’t a paver defect. It’s groundwater saturating the base from below, which is a drainage problem first and a cosmetic problem second.
- Base failure and differential settling over engineered fill. Communications Hill was built on fill. If the fill wasn’t compacted to spec before pavers went down, you get low spots, lippage between pavers, and eventually paver cracking. We excavate to the fill, compact properly, and rebuild the base rather than patching the surface.
- Edge restraint separation at driveway aprons. The transition where your driveway meets the street takes the worst of it. Water concentrates there, and without proper edge restraint the pavers spread. We saw this exact failure on Communications Hill Boulevard, which we’ll get to below.
- Retaining wall drain failures undermining paver patios. On terraced lots, a failed drain behind a retaining wall doesn’t just wet the wall. It can saturate the soil under a patio twenty feet downhill and slowly undermine the paver base from below. By the time you see the patio sinking, the water has been working for months.
Unilock Service in Communications Hill: What Local Conditions Mean for Your Equipment
Communications Hill sits on engineered fill and retaining-wall terraces, which means a Unilock paver driveway or patio here is only as good as the drainage that carries uphill runoff around it. On streets like Cottle or Communications Hill Boulevard, water from an uphill neighbor’s downspout or a failed retaining-wall drain can surface in a downhill home’s garage, and that same water is what undermines a paver base from below. You won’t see this failure mode on flat, grid-platted streets—or over in Unilock service in Cambrian Park. That’s why we read the hillside drainage pattern and HOA palette before we ever quote a Unilock driveway or patio in this community. The paver is the visible part. The base and the water are the job.
Here’s a field vignette from our own work. On a Communications Hill Boulevard driveway, we pulled a Unilock Brussels Block apron that had heaved and spread at the street transition after winter runoff from an uphill neighbor’s downspout saturated the base. We excavated to the engineered fill, re-graded to a positive slope, installed a new open-graded base and Unilock edge restraint, and tied the downspout into a proper drain. The pavers have stayed locked through two rainy seasons since. That’s what proper Unilock construction looks like on this hill: fixing the water before we lay the paver.
Unilock Models & Products We Service in Communications Hill
We install and repair Unilock’s core paver lines: Brussels Block, Elegance, Umbriano, and Beacon Hill. Each line has its own profile and intended use. Brussels Block reads like an old-world cobble and takes a beating on driveways. Elegance gives you a tighter joint and a more contemporary face. Umbriano’s shot-blasted surface handles pool decks and patios where barefoot traffic and wet conditions are common. Beacon Hill, with its tumbled edges, suits walkways and courtyard settings.
We use Unilock’s own edge restraints and joint sand on every job. The reason is simple: the base and the edge are where hillside installs fail, not the paver face. If a patio or driveway has a solid base and only surface wear, we reset and re-sand rather than replace. If the base has failed, we rebuild it. No shortcuts, and no upselling you into a full replacement when the pavers themselves are still serviceable.

FAQs – Unilock Construction in Communications Hill
Yes, if the base is built right and the edge restraint is properly installed. The pavers themselves won’t slide. What fails on a slope is the base beneath them and the edge holding them in. We install Unilock edge restraints and compact the base in lifts, then grade the drainage so water doesn’t run through the base and carry the joint sand with it. Call (833) 589-8103 if your driveway is already showing spread at the apron.
That’s efflorescence, and on Communications Hill it usually means water is wicking up through a saturated base. The white deposit is mineral salt left behind as the water evaporates. It’s not a paver defect. The fix is resolving the drainage that’s keeping the base wet, then cleaning the surface. We can diagnose where the water is coming from and correct it.
Communications Hill has a narrow builder palette of Mediterranean and Spanish-style elevations, and most HOAs here enforce material and color ranges. Unilock’s tumbled and cobble-style lines like Brussels Block and Beacon Hill often read as compatible with that palette, but every HOA is different. We can help you prepare the submittal with product specs and a sample. It’s worth checking your CC&Rs before you commit to a product.
It affects it directly. On a flat lot, you’re paying for excavation, base, and pavers. On a terraced Communications Hill lot, we’re usually adding drainage, sometimes retaining wall repair, and always more base compaction to handle the slope. That pushes the cost toward the upper end of the $3,500 to $11,000 patio range. A free estimate will give you an exact number. Call (833) 589-8103 to book one.
Usually, yes. If the base is intact and the issue is surface-level joint sand loss or minor edge spread, we reset the affected area and re-sand it without pulling the whole driveway. If the base has failed, we rebuild it, often reusing the same pavers. Pavers don’t wear out the way concrete does. The base is what fails.
