Unilock Construction in Ben Lomond, CA

Unilock Construction in Ben Lomond, CA | Viceroy Construction

Viceroy Construction installs, repairs, and rebuilds Unilock paver patios, driveways, and segmental retaining walls throughout Ben Lomond, CA, and provides Brookdale Unilock service as well. We’re an independent contractor, not a Unilock dealer or authorized service center. What sets our Unilock work apart here is straightforward: Ben Lomond’s steep slopes, expansive clay, and WUI fire-review requirements demand a different build sequence than flatland jobs, and we’ve been doing that work long enough to know what fails and why.

Why Ben Lomond Residents Choose Us for Unilock Service

Most Unilock failures we see in Ben Lomond didn’t start with the block. They started with what went under it. Base material, drainage, geogrid, grading. Get those wrong on a rain-saturated hillside lot and you’ll be rebuilding inside five years. Neil Drummond, our owner, trained in the building trades program at West Valley College and spent decades framing, pouring concrete, and scoping structural work across the South Bay. He brings that structural eye to every Unilock project, because a retaining wall on a Ben Lomond slope is a structural element, not a landscaping feature. We use genuine Unilock units, matching edge restraints, and polymeric sand on every repair so the fix blends with the existing field. And we’ll tell you honestly when a wall needs to come down to its base rather than get patched. The details you don’t see are the ones that matter most.

Common Unilock Construction Problems We Solve in Ben Lomond

• Bulging and cracking Unilock Pisa2 and Thornbury walls. We regularly pull apart walls in Ben Lomond that were backfilled with native clay and no geogrid. After a wet winter, the saturated soil pushes outward, the wall shears, and the face starts to lean. The fix is a full rebuild with engineered geogrid and free-draining gravel, not a fresh course of block on top of the same bad base.
• Settling and rocking Brussels Block pavers. Ben Lomond’s expansive mountain clay swells when it rains and shrinks when it dries. Pavers laid on a thin base over that clay will heave, settle, and rock within two or three seasons, opening joints and pooling water against your foundation or stem wall.
• Efflorescence and surface spalling. Redwood canopy debris, heavy shade, and poor grading keep Unilock surfaces wet for months at a time on some Ben Lomond lots. That trapped moisture pulls salts through the paver, leaving white efflorescence blooms and, eventually, spalled faces that can’t be cleaned off.
• Polymeric sand joint failure on sloped driveways. Storm runoff moving fast down a Ben Lomond driveway scours the joints before polymeric sand can fully cure, especially if the installer skipped edge restraints. Loose joints lead to shifting pavers and creeping edges.
• Water pooling against foundations. When a paver patio or walkway settles even half an inch toward the house, it redirects runoff into the crawlspace or against the pier-and-beam foundation. On Ben Lomond hillside lots, that water doesn’t dry out quickly, and rot and erosion follow.

Unilock Service in Ben Lomond: What Local Conditions Mean for Your Equipment

Here’s something most out-of-area hardscape crews don’t grasp until it bites them: lots under the Highway 9 redwood canopy often can’t meet the WUI defensible-space radius without fuel thinning or tree removal. That means a paver patio or driveway rebuild can stall in Cal Fire clearance and county WUI review before the first course of Unilock block ever goes down. We learned this the hard way years ago and now sequence hardscape permits around the fire review, not after it. On a sloped lot off Highway 9 in Ben Lomond, we rebuilt a failing Unilock Pisa2 retaining wall that had been backfilled with native clay and no geogrid, so it had bulged and cracked after a wet winter. Our crew pulled the wall, installed engineered geogrid and gravel drainage, reset the Unilock units, and tied the patio above into proper grading so storm runoff now sheds away from the pier-and-beam foundation instead of into it. That’s the difference between a Ben Lomond hardscape job done right and one that becomes somebody’s expensive problem in five years.

Unilock Models & Products We Service in Ben Lomond

We install and repair the full Unilock hardscape range, including Brussels Block pavers, Beacon Hill flagstone pavers, Pisa2 segmental retaining wall systems, and Thornbury retaining wall block. For repairs, we use genuine Unilock units and matching edge restraints and polymeric sand, because off-brand blocks won’t color- or dimension-match an existing field, and the patch will always look like a patch. For drainage and base work, we spec quality geotextile, compacted aggregate, and geogrid rather than whatever’s cheapest at the local yard. We keep a working stock of the most common Unilock paver profiles and edge restraints for Ben Lomond repairs, which speeds up small fixes on the Highway 9 corridor.

FAQs – Unilock Construction in Ben Lomond

Can a Unilock paver patio be built on a steep Ben Lomond hillside lot without a big retaining wall? Sometimes, but it depends on the grade and where the water goes. Slopes under about 5% can often be graded and built without a wall. Steeper sites usually need a Pisa2 or Thornbury segmental wall with geogrid to hold the patio and control runoff. Call (877) 358-6557 and we’ll walk the site before you commit to anything.

Why did my Unilock Brussels Block pavers sink and rock after last winter’s storms? Because the base couldn’t handle Ben Lomond’s expansive clay. When clay gets saturated, it swells and softens, and a thin or poorly compacted base will settle unevenly. The fix is pulling the field, excavating the bad material, and reinstalling over compacted aggregate with proper drainage. Patching individual pavers won’t hold.

Does a paver driveway need WUI or Cal Fire review in Ben Lomond? If your lot sits under the Highway 9 redwood canopy and can’t meet the 100-foot defensible-space radius, yes. Cal Fire clearance and county WUI review can precede the building permit. We sequence that into the project schedule from day one so the driveway doesn’t stall mid-build.

Will new Unilock pavers match the older ones already on my property? We source genuine Unilock units in the same color and profile as your existing field. There may be slight surface wear differences between old and new, but the dimensions and color line will match. Off-brand lookalikes won’t.

How do you keep a Unilock retaining wall from failing on a rain-soaked Ben Lomond slope? By building it as a structural wall, not a stacked block wall. That means engineered geogrid layers, free-draining gravel backfill, a proper drainage pipe at the base, and compaction in lifts. Walls built that way handle Ben Lomond winters. Walls built with clay backfill don’t. Call (877) 358-6557 for an exact quote on your wall.
