Unilock Construction in Communications Hill, CA | Viceroy Construction
Viceroy Construction provides independent Unilock paver, retaining wall, and hardscape installation across Communications Hill. We are not a Unilock dealer and we are not authorized by the manufacturer, but our crew has been laying Unilock systems on these slope-terraced lots long enough to know how they behave on reclamation fill. When a Brussels Block driveway heaves or a Rivercrest wall starts leaning, the base underneath is usually the problem. Call (877) 358-6557 for a free estimate.
Why Communications Hill Residents Choose Us for Unilock Service
Unilock pavers and wall units are only as good as the ground beneath them, and Communications Hill ground is unlike almost anywhere else in San Jose. The community sits on a former quarry and landfill-reclamation hilltop, which means engineered fill, buried debris, and expansive clay show up on nearly every job, a challenge we also handle with Unilock in Buena Vista. Our crew knows to proof-roll before base course goes down. Neil Drummond, our owner, grew up in the Saratoga foothills and trained in the building trades program at West Valley College, where framing, concrete, and structural coursework built the foundation for how he scopes paver and wall work today. He walks every Communications Hill job himself before calling it done.
We use genuine Unilock units, caps, joint sand, and geogrid systems rather than off-brand lookalikes. Color and dimensional match matter when you repair a partial run on an existing terrace. As an independent installer, we are not sponsored or endorsed by Unilock, but we know their product lines cold. Our full Unilock sales & service capability covers the entire Communications Hill service area in ZIP code 95136.

Common Unilock Construction Problems We Solve in Communications Hill
- Paver heave on driveways. Expansive clay soils on the hilltop swell after winter rain. If the base was not over-excavated and separated with geotextile fabric, Brussels Block pavers heave in a wave pattern every wet season. We pull the run, rebuild the base, and re-lay with a permeable joint.
- Retaining wall bulging or leaning. Copthorne and Rivercrest wall blocks set on engineered fill without proper geogrid reinforcement and drainage aggregate eventually lean. This shows up most on the lower terraces of Communications Hill where fill depth is greatest.
- Efflorescence and surface staining. Where slope drainage gets routed toward the foundation, water ponds against the house and leaves white mineral deposits on Brussels Block and Beacon Hill Flagstone. We regrade the slope and rework the drainage before touching the pavers.
- Settled or rocking pavers. Buried quarry debris and reclamation fill that was never proof-rolled before base placement causes pavers to settle unevenly. This is a Communications Hill signature problem. Patching individual units without fixing the base just moves the problem six months down the line.
- Permeable system failures. Eco-Optiloc and other permeable joint systems clog when uphill runoff carries clay fines into the joints. On Communications Hill, drainage design has to account for where the hill sheds water during heavy rain, or the system stops draining.
Unilock Service in Communications Hill: What Local Conditions Mean for Your Equipment
Communications Hill sits on a former quarry and landfill-reclamation hilltop, so Unilock base prep here routinely turns up engineered fill and buried debris that has to be proof-rolled and over-excavated before any paver or retaining wall goes down. That is a step most flat-lot installs never need, and skipping it is why so many hardscape projects on this hill fail within a few wet seasons. On a terraced lot off Communications Hill Boulevard, a homeowner had a Brussels Block driveway where the pavers were heaving in a wave pattern every winter, similar to issues we address with Unilock service in Cambrian Park. We pulled the run and found the base sitting directly on reclamation fill with no separation fabric. We over-excavated, re-compacted, added geotextile and fresh aggregate, then re-laid the Brussels Block with a permeable joint and regraded the slope drainage away from the garage. Two winters later the drive is still flat and the joints hold their sand.
This is the only page that explains why Unilock hardscape work on Communications Hill starts with proof-rolling reclamation fill and drainage design. The base conditions decide whether pavers and walls survive the wet season. Everything we do here starts from that reality.
Unilock Models & Products We Service in Communications Hill
We install and repair the Unilock product families that dominate Communications Hill landscaping: Brussels Block and the Brussels Dimensional System for driveways and patio borders; Beacon Hill Flagstone for patios and walkway landings; Richcliff and Copthorne tumbled wall units for retaining walls and step risers; Eco-Optiloc and permeable joint systems for hardscape drainage; and Ledgestone and Rivercrest wall systems for the terraced retaining walls this community needs.
We stock genuine Unilock caps, joint sand, and geogrid locally for fast turnaround on Communications Hill repairs. When a wall or driveway has failed at the base or drainage layer, we say so plainly. Rebuilding the base beats patching pavers that will just move again.

FAQs – Unilock Construction in Communications Hill
Your pavers are heaving because expansive clay beneath them swells when it gets wet, and the base was likely never over-excavated or separated with geotextile fabric. On Communications Hill the fill is reclamation material with a high clay fraction, so the swelling is worse than flatland San Jose. The fix is rebuilding the base, not resetting pavers. Call (877) 358-6557 and we will tell you what the scope looks like after a site visit.
Yes, but not without geogrid reinforcement and proper drainage aggregate behind the wall. Engineered fill on Communications Hill settles unevenly over time, and Copthorne or Rivercrest walls set directly on it will lean or bulge. We proof-roll the fill, over-excavate where needed, and design the drainage so the wall is not holding water uphill of the terraced streets.
If pavers are heaving, rocking, or settling in a repeating wave pattern, the base has failed. If you see isolated cracks or chipped units with flat, stable surrounding pavers, that is a paver-level issue. On Communications Hill, the base is overwhelmingly the culprit, a pattern we’ve seen providing Unilock in Seven Trees as well. We will pull a section and show you what is underneath before recommending any repair.
On Communications Hill, slope drainage often gets routed toward the foundation when patios and driveways were built without proper regrading. Water pools, then wicks through the pavers and sits against the slab, causing efflorescence and staining on Brussels Block and Beacon Hill. The fix is regrading the slope and reworking the drainage, not just sealing the pavers. Call (877) 358-6557 for a drainage assessment.
A paver driveway in Communications Hill typically runs $7,000 to $18,000 depending on size, base conditions, and access. A paver patio runs $3,500 to $11,000. Reclamation fill and slope work add to prep cost, which is why local pricing sits at the higher end of the Bay Area range. Our estimates are free and itemized, so you see exactly where the money goes.
