Unilock Construction in Sunnyvale, CA | Iron Beam Contractors
We set Unilock sales & service pavers and walls on Sunnyvale’s flat, clay-heavy former orchard lots every month, so we know how their profiles, thicknesses and base requirements actually behave under local grading and winter drainage loads. We’re an independent installer with no authorization, partnership or warranty endorsement from Unilock. What we do have is hands-on experience with Brussels Block, Stoneridge, Beacon Hill and Sierra wall block on real Sunnyvale projects from the 94085 ZIP up through 94087 and 94088, and we price every job with a written line-item quote before a single paver gets touched. Call (833) 756-5936 for a free estimate.
Why Sunnyvale Residents Choose Us for Unilock Service
Most contractors can lay pavers. Far fewer can tell you why a paver driveway on a Sunnyvale clay subgrade will rut at the apron within three winters if the excavation never hits compacted aggregate. Nolan Driscoll, our owner, built Iron Beam Contractors on the idea that a homeowner should know exactly what’s in the ground before we open it, not after. That’s why our Sunnyvale General Contractor work on Unilock projects always starts with a base inspection, not a sales pitch.
We stock genuine Unilock units for color-matched repairs, and we carry quality domestic aggregate, polymeric joint sand and geogrid that perform as well as or better than brand-specific base products. When your existing patio is sound but the joints have washed out, we repair the base and restraints rather than tear the whole field out. When the structural units are cracked through or the base has failed under the entire field, we say so and price the replacement honestly. One contractor, every phase. That’s the whole point.

Common Unilock Construction Problems We Solve in Sunnyvale
- Efflorescence haze and sand-joint washout after wet winters. Sunnyvale’s Mediterranean climate dumps rain between November and March, and pavers laid on a thin base with no edge restraint on flat lots hold water at the surface. The white haze is efflorescence from moisture migrating through the units; the sandy joints wash out when grade doesn’t carry water away. We fix both with proper base correction, drainage and joint re-stabilization.
- Rutting and lippage at driveway aprons. On Sunnyvale’s clay-heavy soils, a paver driveway that wasn’t excavated deep enough will move under vehicle load. You see it first at the apron where tires turn. The subgrade gets over-excavated to clean aggregate before any Unilock unit goes back down.
- Chipping and spalling along sawn edges of Brussels Block. Dry cuts and uneven tamping leave fractured edges that chip under foot traffic within a year. Our crews wet-cut and tamp in sequence, and we replace spalled units with genuine Brussels Block so the color and profile match.
- Segmental retaining wall bulging. Sierra-type blocks built without geogrid on saturated backfill begin to lean at the middle course. On Sunnyvale’s flat lots, backfill saturation is common where drainage wasn’t designed into the wall. We rebuild with proper geogrid reinforcement and drainage stone.
- Patio settlement over agricultural fill. Sunnyvale was orchard land before it was subdivisions. Fill sits under many lots, and it settles unevenly. Patios that sink in year two or three usually trace back to base prep that never accounted for what was under the topsoil.
Unilock Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Sunnyvale sits at the center of Silicon Valley’s teardown-and-rebuild economy. Much of its post-war single-story ranch housing stock, especially in the 94085, 94086 and 94087 ZIPs, is being scraped and replaced with larger two-story homes, ADUs and multi-unit infill. That means our Unilock in Santa Clara work here rarely happens on a clean, undisturbed lot. We’re usually tying a new paver patio or driveway into a construction site where the original 1950s lot lines, old irrigation and orchard remnants are still in the ground. Digging base for a paver patio or driveway on Sunnyvale’s former orchard lots routinely turns up old orchard tree roots, buried irrigation lines and agricultural fill, so our paver base excavation here often becomes a mini site-clearing job that a typical suburb never sees. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam.
Unilock Models & Products We Service in Sunnyvale
We work across the Unilock lines most common in Sunnyvale residential projects. Brussels Block and Stoneridge handle patios and walkways where a tumbled, natural stone look fits the mid-century neighborhood character. Beacon Hill gives a cleaner, more contemporary edge for two-story rebuilds and modern infill. Sierra wall block handles low retaining walls, planter perimeters and grade transitions on flat lots.
For parts and matching, we source genuine Unilock units and edge restraints where color and dimension continuity matter. The base is built from quality domestic materials, not brand-specific upcharges. What’s in stock locally in Sunnyvale keeps typical patio repairs and driveway edge fixes moving fast without waiting on special orders. If you want to know what a repair looks like before we touch anything, we’ll walk your site and tell you.

FAQs – Unilock Construction in Sunnyvale
Because Sunnyvale was orchard land before it was residential, and what’s under your topsoil isn’t always predictable until the excavator opens it. Old root mats, buried irrigation lines and agricultural fill often mean additional over-excavation and clean aggregate before we can build a stable base. We quote the visible scope first and walk you through any below-grade findings before adding cost. Call (833) 756-5936 for a free site assessment.
Yes, if the base is built correctly. The failures we see in Sunnyvale are almost always from thin base, no edge restraint or poor drainage on flat grades. With proper excavation to compacted aggregate and edge restraint, Unilock driveways handle the rainy season well. We build for drainage first, pavers second. Call (833) 756-5936 and we’ll check your current driveway.
We use genuine Unilock units when color, profile and dimension continuity matter on your project. For base materials, we use quality domestic aggregate, polymeric sand and geogrid because they perform as well or better than brand-specific versions and don’t inflate your cost. We’ll tell you exactly what goes into the job.
Repair is usually the answer if the structural units are sound. The white haze is efflorescence from moisture movement, and shifting joints mean the base and edge restraint need correction. We repair the base, re-set the joints and re-stabilize the field rather than tear out a patio that still has decades of life. If the base has failed under the whole field, replacement is the honest call. Call (833) 756-5936 for a patio inspection.
Yes. Much of our Unilock in Cupertino patio work in Sunnyvale is tied to new ADUs and additions, where the paver field has to integrate with new footings, drainage and grade transitions. On a rebuild in the 94087 ZIP, our crew was setting a Brussels Block patio behind a new two-story replacement home when the excavator hit an old orchard root mat and buried irrigation under the planned base. We over-excavated to clean compacted aggregate, added edge restraint on the flat lot and re-laid the field, and the patio now drains away from the new ADU instead of pooling against its footing. Call (833) 756-5936 to plan your project.
