Unilock Construction in East Foothills, CA | Viceroy Construction
Viceroy Construction installs and repairs Unilock segmental retaining wall and paver systems across East Foothills, and we build every wall to County of Santa Clara steep-slope and WUI standards rather than flat-lot San Jose assumptions. We’re an independent contractor with no affiliation to, or authorization from, Unilock. The short version: if you own a Unilock wall or paver field in East Foothills, call (877) 358-6557 and we’ll walk the slope with you and tell you exactly what’s moving and why.
Why East Foothills Residents Choose Us for Unilock Service
Neil Drummond grew up in the Saratoga foothills and trained in the building trades program at West Valley College, where the coursework in framing, concrete, and structural work still shapes how we scope a wall rebuild. That background matters in East Foothills because Unilock work here is never flat, never simple, and never forgiving of shortcuts. We see walls that were built as if they sat on a Saratoga lot, and that’s exactly the problem. The details you don’t see are the ones that matter most.
We know the Unilock product lines, we know what fails on them in this specific soil, and we know what the county requires before a wall goes in. Residents here get one point of contact who owns the entire scope, from geogrid to capped course, rather than a patchwork of subs who don’t talk to each other. And because we’re general contractors, not a specialty paver crew, we can handle the drainage, the retaining, the concrete, and the hardscaping under one contract.
For Unilock sales & service across this part of the foothills, our approach is simple: rebuild the base, match the units, and build it for the slope it actually sits on.

Common Unilock Construction Problems We Solve in East Foothills
Most of the Unilock failures we see in East Foothills share a root cause: the wall or paver field was built for a flat lot. Here’s what walks through our schedule week to week:
- Racked and leaning Pisa2 walls. East Foothills sits on deep expansive clay that swells every wet season. Where the base wasn’t over-excavated and choked with compacted aggregate, the courses rack and the wall leans. We see it constantly on older walls built without county review.
- Scoured Brussels Block paver fields. Dry-season runoff off the brush slopes above Alum Rock Park moves fast. It jets fines out of open paver joints and drops the field into voids. Flat-lot base prep never anticipated that kind of water velocity.
- Heaved Beacon Hill Flagstone at the toe of slopes. Tumbled pavers tent and lift where a wall’s drain and daylighted footing are missing. That’s the signature of older hillside installations built without permits, and it gets worse every winter.
- Bulging U-Cara wall faces above old retaining tiers. East Foothills has plenty of settled, unpermitted retaining walls. When a new wall is surcharged above one and the geogrid wasn’t designed for that load, the face units separate. That’s a design failure, not a material failure.
- Drainage failures behind walls on steep lots. Unilock wall sections will hold up fine, but only if water moves through them and away. Where the footing drain is missing or clogged, hydrostatic pressure pushes the whole wall downslope. In East Foothills this happens fast.
Unilock Service in East Foothills: What Local Conditions Mean for Your Equipment
Here’s the thing most people miss about East Foothills: it’s unincorporated County of Santa Clara land, not the City of San Jose. That means a Unilock retaining wall or paver driveway here needs a county steep-slope and geotechnical review that a valley contractor’s San Jose permit will not satisfy. Add the WUI fire rules on top of that, and you have defensible-space limits that control how close hardscape can sit to brush. A contractor who pulls a San Jose permit makes a mistake you don’t discover until a county inspector or your insurer gets involved, which is why experience with Unilock in San Jose doesn’t automatically translate to East Foothills compliance. On a steep lot off the Alum Rock Park slopes above 95127, we rebuilt a racked Pisa2 garden wall whose base had been set on native clay without over-excavation or drain gravel. We over-excavated to compacted aggregate, re-set the units with geogrid and a daylighted footing drain, and tied in a Brussels Block patio. The wall has held through the last two rainy seasons.
That’s the whole difference. It’s not the paver brand that fails here. It’s the assumption that East Foothills behaves like the valley floor.
Unilock Models & Products We Service in East Foothills
We service the Unilock lines most common on East Foothills properties: Brussels Block and Brussels Dimensional pavers, the Pisa2 retaining wall system, Beacon Hill Flagstone, and the U-Cara multi-piece wall system. For visible courses, we match Unilock’s own units and caps. For the buried components Unilock doesn’t manufacture, like geogrid, drain gravel, and filter fabric, we use compatible products from proven suppliers. The repair-versus-replace call is made on the slope, not over the phone. If a base and drainage can be rebuilt, we rebuild. We only replace full fields when clay movement has fractured units or undermined the footing beyond re-leveling.
This is work we do across the entire East Foothills service area, and we keep our approach consistent: match the unit, build the base, and don’t send you a bill for work that won’t hold.

FAQs – Unilock Construction in East Foothills
We install a daylighted footing drain wrapped in filter fabric behind the wall, backfill with compacted aggregate, and grade the surface so water never ponds against the back of the units. On East Foothills slopes, that drain is mandatory, not optional. If yours is missing or clogged, we can often add it without tearing out the entire wall. Call (877) 358-6557 and we’ll tell you what your wall actually needs.
No. We’re an independent contractor with no affiliation to, or authorization from, Unilock. That independence means we install what’s right for your slope and your county permit, not what’s easiest for a manufacturer program. We use Unilock’s own units and caps for visible courses and compatible buried components from proven suppliers.
For visible courses we match Unilock’s own units and caps from the same product lines, so the repair blends with the original wall. For geogrid, drain gravel, and filter fabric, Unilock doesn’t manufacture those components, so we source them from proven commercial suppliers that meet county geotechnical specs. If matching is important to you, we’ll tell you before we order.
Most rebuilt wall sections take three to seven days once the county review clears, depending on the height of the wall and how much over-excavation the slope requires. Paver patios and driveways run about five to ten days. The geotechnical review is often the longest single step, and we handle that as part of the permit package. Call (877) 358-6557 for a schedule that fits your site.
Because the county’s steep-slope and WUI fire rules add engineering, over-excavation, drainage, and sometimes defensible-space reconfiguration that flatland work never touches. You’re not paying more for the same wall, you’re paying for a wall that holds. Call (877) 358-6557 for an exact quote on your slope, estimates are free.
