Unilock Construction in Simi Valley, CA | Elmstead Remodeling Ventura
We provide independent Unilock paver and retaining wall service across Simi Valley, from Texas Tract driveways to Wood Ranch slope walls. What makes our Unilock work different here is simple: we build for adobe clay soil that swells in winter and shrinks to dust in summer, because that’s the one factor behind nearly every Unilock failure we see in this city. Call (341) 218-4316 for a free estimate on paver driveways, patios, and U-Cara walls. We’re not a Unilock dealer or authorized service center; we’re a General Contractor - Simi Valley who installs and repairs their products every week.
Why Simi Valley Residents Choose Us for Unilock Service
Graham Stein spent two years in the building technology program at Los Angeles Trade-Technical College studying framing, finish work, and reading structural plans before he ever picked up a client’s key. That background matters when you’re laying a Brussels Block driveway on clay that moves an inch or more between seasons. Our crew knows which Unilock product lines hold up under Santa Ana winds and slab-level shifts, and which need extra base prep before a single paver goes down.
Most Simi Valley paver failures aren’t the paver’s fault; they’re the base’s fault. We’ve pulled up driverways and patios across this city where the original sand base had turned into mudstone from decades of irrigation runoff meeting shrink-swell clay. That’s the problem we solve, and it’s why homeowners call us when a fly-by-night “paver guy” laid Hollandstone directly on native soil and it crept apart in two summers.
We extend the Unilock sales & service knowledge we’ve built over more than a decade to every new install and repair in Simi Valley. Written price before any work starts, every time. Drop cloths and shoe covers on every visit. And a 365-Day Done Right Promise: if it’s not done right, we make it right.

Common Unilock Construction Problems We Solve in Simi Valley
- Brussels Block driveway settlement and edge chipping: The original 1960s and 70s ranch slabs under many Simi Valley driveways are cracked from decades of clay expansion, and the pavers above them shift every wet winter. We see chipped edges where the slab has tilted and vehicles catch the paver lip.
- Hollandstone walkway creep and blown sand joints: When summer heat bakes out soil moisture, the sand between joints dries, blows out, and the pavers begin to creep apart. Walkways in Wood Ranch and central Simi Valley show gaps that widen every August.
- U-Cara Multi-Face retaining wall lean: Adobe soil swells behind walls after winter rains, and walls without drainage behind them lean outward or crack at the soldier-course top. This is especially common on Wood Ranch slopes with west-facing sun exposure.
- Efflorescence and surface spalling from hard irrigation water: Simi Valley’s water plus repeated wet-dry cycles leave a white chalky residue on Richcliff and other Unilock lines. Left untreated, the surface can spall in small flakes.
- Uneven paver settlement from original sand-only bases: Ranch homes built on expansive clay often had original paver work done with a thin sand bed over native soil. That base turns to mudstone within a decade, causing the surface to dip and shift.
Unilock Service in Simi Valley: What Local Conditions Mean for Your Equipment
Simi Valley requires a geotechnical soils report for any retaining wall over three feet or any paver project that changes drainage on a hillside lot. Our Unilock work in Texas Tract almost always triggers that requirement because of the city’s strict hillside grading ordinance tied to the adobe clay shrink-swell cycle. Here’s what that means in practice: if you want a U-Cara Multi-Face wall on a slope, or a paver patio that redirects runoff, the city wants to know what’s under the surface before you move dirt. We handle that paperwork, coordinate the report, and build the base to satisfy the engineer’s recommendations. It adds a step, but it’s the reason our walls don’t lean out after two wet winters while the neighbor’s wall does.
What we learn from those geotechnical reports shapes every job. In Texas Tract specifically, the clay layer under the topsoil can hold moisture for months, then contract dramatically in summer. The base prep that keeps a driveway level in Ventura won’t work here without a geogrid or geotextile separator. That’s the difference between a paver job that lasts fifteen years and one that dips in three.
Unilock Models & Products We Service in Simi Valley
We work with Brussels Block, Hollandstone, Richcliff, and U-Cara Multi-Face product lines. For any repair where less than about 10% of a surface needs re-leveling, we source genuine replacement pavers and matching joint sand from Unilock’s local distributor, not generic big-box pavers. The color and chamfer on Unilock molds are specific; a big-box “close enough” paver will always read as a patch. Beyond that threshold, we recommend a full paver reset with a geotextile separator over the clay to prevent future heave.
We keep common Unilock joint sands and edge restraints in our local supply run for fast turnaround on Simi Valley repairs. For full driveways and patios, we order direct from the distributor so the dye-lot matches across the entire surface.

AfterUnilock Service Pricing in Simi Valley
Pricing for Unilock work in Simi Valley depends on how much base correction the clay demands. A simple paver patio on a flat lot costs less than a Brussels Block driveway on a 1972 ranch slab that needs a full base rebuild with geogrid. Here’s what we quote across the city:
| Project | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |

FAQs – Unilock Construction in Simi Valley
Yes, when the affected area is under about 10% of the surface, we source genuine Brussels Block pavers from Unilock’s local distributor and match the joint sand so the repair blends with the original mold and chamfer. We never use generic big-box pavers as substitutes. If your driveway has settled in the middle like many 1970s Texas Tract ranches, we may recommend resetting the whole surface instead of patching half, because the base under the undamaged half is usually failing too. Call (341) 218-4316 and we’ll come look at it.
Re-sanding alone won’t work because the clay below your walkway is shrinking in summer and the sand joints are blowing out as the pavers creep apart. The long-term fix is pulling the Hollandstone, installing a compacted Class II base with a geotextile separator over the native clay, then relaying the same pavers with polymeric sand. That stops the creep and keeps the weeds out. Call (341) 218-4316 for a free estimate.
Under three feet typically doesn’t require a permit, but Simi Valley’s hillside grading ordinance means any wall on a slope or any project that changes drainage may still need a geotechnical soils report. Wood Ranch and Texas Tract lots frequently trigger this. We’ll check your specific property before you commit to anything, and we handle the paperwork if a report is required. Call (341) 218-4316 and we’ll walk the site with you.
That’s efflorescence, and in Simi Valley it’s driven by hard irrigation water plus repeated wet-dry cycles. Mineral salts in the water wick through the paver surface and crystallize as a white film. We can clean it and apply a breathable sealer that slows the cycle, but the real fix is adjusting your irrigation so it doesn’t soak the paver surface every day. Call (341) 218-4316 and we’ll take a look.
If the pavers themselves are intact, yes. We pull them, rebuild the base with Class II compacted stone and a geotextile separator over the clay, then relay the same Hollandstone pavers. The creep you’re describing is almost always a failed base, not failed pavers. If some pavers are cracked or spalled, we’ll match them from the distributor so the color stays consistent. Call (341) 218-4316 for an exact quote.
