Unilock Construction in Mountain View, CA | Seaside Contractors
We provide Unilock sales & service for segmental pavers and retaining-wall systems across Mountain View every week, and we work directly from Unilock’s published base, edge-restraint and compaction specs rather than from whatever a truck driver says. The one thing that makes our Unilock work here different: we know Mountain View’s permitting culture means a paver driveway or patio expansion tied to a second-story addition or ADU gets plan-checked against lot coverage and drainage before we can excavate. We’re an independent contractor, not authorized or sponsored by Unilock. Call (833) 589-8103 for a free estimate.
Why Mountain View Residents Choose Us for Unilock Service
We work on Unilock hardscape in our Mountain View service area neighborhoods from Waverly Park to Blossom Valley, and we’ve seen what happens when an edge restraint gets face-nailed into soft soil instead of set against a slab-on-grade Eichler foundation. The pavers creep. Joints open. The plastic edge bends and the whole field starts moving. Our crew knows the difference because we’ve fixed enough of those failures to understand what the original installer skipped.
Glen Sorrento, our owner, studied building construction technology at College of San Mateo and has spent two-plus decades working through nearly every project type the Peninsula throws at a contractor. When we spec a Unilock Brussels Block driveway or a Beacon Hill patio in Mountain View, it’s not a guess. It’s built on years of watching hardscape perform, fail, and get repaired in this exact climate and housing stock. We buy genuine Unilock units and matching edge systems so color and dimension stay consistent with an existing field. We substitute only where Unilock has discontinued a color and a documented near-match is the honest option.

Common Unilock Construction Problems We Solve in Mountain View
- Edge restraint failure on driveways squeezed between an Eichler foundation and the property line. Mountain View’s post-war tract homes sit close to lot lines, and the plastic edge often gets face-nailed into soft soil instead of set against the footing. Pavers creep, joints open, and the field drifts. We reset the edge against the concrete footing where possible, not into dirt.
- Base saturation and pumping on low-pitch patio aprons where roof runoff dumps directly onto the pavement. Mountain View’s rainless summers lull people into ignoring drainage, but the wet winter is when the damage shows. An open-graded base clogs with fines and units rock and settle. We re-grade so water moves away from the slab before we lay a single paver.
- Efflorescence and joint-sand loss on patios installed late in the dry season. A patio built in September without a drainage path looks fine until the first December storm. Polymer sand washes out and white bloom shows on darker Unilock units. We’ve seen it on Beacon Hill patios across Mountain View.
- Unit spalling and corner chip at driveway aprons where construction traffic rolled over foot-traffic-rated pavers. When a second-story addition or ADU brings loaded material trucks onto a paver driveway spec’d for passenger cars, the corners chip. We match the original unit and replace the damaged field. If the base is still sound, we don’t tear out the whole driveway.
- Root heave and settlement on patios built over old tree roots along post-war ranch lots. Mountain View’s mature street trees send roots under hardscape. We excavate, remove problem roots, and set a proper open-graded base with edge restraint so the new patio doesn’t follow the old failure.
Unilock Service in Mountain View: What Local Conditions Mean for Your Equipment
Mountain View’s permitting culture is unusually process-heavy and online-review-driven. A paver driveway, patio expansion, or hardscape tied to a second-story addition or ADU gets plan-checked against lot coverage and drainage before we can excavate. On these small, fully built-out lots, the hardscape square footage is often the item that pushes a project over the coverage threshold and stalls the permit. Our team accounts for that on day one. We don’t wait until the plans come back red-tagged. We measure lot coverage, check the drainage path, and design the hardscape to pass the review the first time. That’s not something a generic paver crew is set up to do. In Mountain View, it’s the difference between a patio that gets built and one that dies in plan check.
Unilock Models & Products We Service in Mountain View
We install and repair the full range of Unilock product lines common on Mountain View’s mid-century ranch and Eichler-style homes. That includes Unilock Brussels Block (the tumbled, chamfered paver for driveways and patios), Unilock Beacon Hill (the flagstone-look paver that shows up on Eichler-era front walks), Unilock Brussels Dimensional Stone (wall block for seat walls and low retaining walls), and Unilock Copthorne (the clay-brick-look paver matched to ranch facades). We keep genuine Unilock units and edge systems in local supply for fast Mountain View turnaround. When a color is long discontinued and the field is otherwise sound, we’ll tell you the truth and offer a documented near-match rather than pretending it’s identical.

AfterUnilock Service Pricing in Mountain View
Hardscape pricing in Mountain View tracks the complexity of the site, not just the square footage. A paver driveway on a flat lot costs less than one that needs drainage re-grading and edge restraint resets against an existing slab foundation. A patio that requires tree-root removal or lot-coverage review adds scope. Here are the ranges we work within:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Concrete Driveway Installation (tear-out comparison) | $4,500 – $12,000 |

FAQs – Unilock Construction in Mountain View
In most cases, yes. Mountain View reviews paver driveway and patio projects against lot coverage and drainage requirements, and hardscape tied to a second-story addition or ADU gets scrutiny on setbacks and neighbor privacy before construction starts. We handle the permit drawings and submissions as part of the project. Call (833) 589-8103 and we’ll check your specific lot before you spend money on plans.
Sometimes, but not as a default. If the concrete has structural cracks, base voids, or slopes toward the garage, an overlay will fail the same way the slab did. On a sound slab with proper pitch, an overlay can work. On the ranch home off Rengstorff Avenue where we replaced cracked concrete with Unilock in Sunnyvale and Mountain View, we pulled the slab because the base was compacted native soil with no drainage. We’ll tell you which situation you have before we recommend a fix.
It means drainage design matters in ways that are easy to miss during the July dry season. Mountain View gets almost no rain from May through October, so a patio with a bad pitch looks fine for months. Then December arrives and roof runoff from low-slope or flat roofs saturates the base, washes out polymer sand, and leaves white efflorescence on darker units. We design the drainage path before we lay the first paver. Call (833) 589-8103 and we’ll check your roof-to-pavement drainage during the estimate.
Yes, often it will. Mountain View’s lots are small and already fully developed. When you add an ADU, the pavers on the front walk or patio expansion are part of the same lot coverage calculation. The hardscape square footage is frequently the item that pushes a project over the coverage threshold and stalls the permit. We measure this early so the hardscape scope doesn’t surprise you after the ADU plans are drawn.
Usually the edge restraint failed. In Mountain View, we see this most on driveways squeezed between a slab-on-grade Eichler foundation and the property line, where the plastic edge was face-nailed into soil instead of set against the footing. If you need Unilock repair in Loyola or nearby Mountain View neighborhoods, we can help. Once the edge lets go, pavers creep outward and joints open, and rain washes the sand through. If the base is sound, we can reset the edge and re-sand without a full tear-out. Call (833) 589-8103 for an exact assessment.
