Unilock Construction in Sacramento, CA

Unilock Construction in Sacramento, CA | Rowan Construction Group

Unilock construction service in Sacramento means working with pavers that face two enemies at once: expansive clay soils that heave and shrink through the year, and summer heat that bakes joints and surfaces. We’re Rowan Construction Group, and we install, repair, and replace Unilock paver driveways, patios, and walkways across Sacramento’s residential neighborhoods, from Land Park bungalows to Natomas flood-zone properties. What makes our Unilock work different here is that we build for the soil movement, not just the aesthetic. Call (470) 298-9650 for a free estimate on any Unilock project.

We’re an independent Unilock service provider. That means we’re not manufacturer-affiliated or an authorized dealer, but we know these products the way a Sacramento contractor should: having installed and repaired Unilock Brussels Block, Courtstone, Richcliff, and Town Hall lines on real local jobsites for years.

Why Sacramento Residents Choose Us for Unilock Service

Sacramento homeowners don’t need another contractor who treats pavers like they’re being installed in San Diego. They need someone who knows what happens when a wet winter swells the clay under a Land Park walkway, then a 100°F July shrinks it back and the pavers shift a quarter inch. That’s the cycle we build for.

We’re led by Grant Rowan, who trained in construction technology at Los Angeles Trade-Technical College and has spent two decades working on residential and light commercial projects across California. His approach is simple: measure twice, say it once, show your work. For Unilock installations and repairs, that means we document the base condition, the compaction, the drainage profile, and the finished surface with photos on every visit. You get a written price before we start and a written scope that says exactly what we’ll do. No ambiguity, no “we’ll figure it out on site.”

We use genuine Unilock replacement pavers whenever possible to ensure color and texture match on existing installations. But we also source high-quality aftermarket edge restraints and polymeric sand that outperform the original in Sacramento’s soil movement. The difference matters. If you’re in Sacramento service area neighborhoods like Curtis Park or East Sacramento, your pavers are sitting on ground that moves more than almost any other California market.

Common Unilock Construction Problems We Solve in Sacramento

• Paver shifting and edge separation from clay soil heave. Sacramento’s adobe clay swells during the November-through-March rainy season and shrinks hard in summer. That cyclical movement pushes Unilock pavers outward at the edges, especially on driveways and walkways without proper edge restraints. We rebuild with geotextile-separated base and reinforced edging that holds the pattern through the cycle.
• Settling and sunken areas over poorly compacted base. The 1950s-1970s slab-on-grade ranch homes across South Sacramento and Arden-Arcade often sit on base material that was never compacted for paver loads. We see sunken depressions where the original base failed. The fix is excavation, re-compaction, and re-laying, not just adding sand on top.
• Efflorescence and surface spalling from hard water and UV. Sacramento’s dry summers concentrate mineral salts at the paver surface, leaving a white chalky film on older Unilock pavers. Prolonged UV and triple-digit heat also degrade the surface layer over time. We clean and reseal where the paver is sound, and replace individual units when spalling has gone too deep.
• Joint sand erosion and paver rocking from winter runoff. Poor drainage on Sacramento properties channels runoff through paver joints during the rainy season, washing out sand and leaving pavers loose. We re-sand with high-performance polymeric sand and, where needed, correct the grading so water moves away from the installation.
• Base failure in flood-zone properties. In the Natomas basin, behind the levees and inside FEMA Special Flood Hazard Areas, standard paver bases can wash out entirely during high-water events. We install permeable base designs and elevated perimeters so floodwater drains without destroying the setting bed.

Unilock Service in Sacramento: What Local Conditions Mean for Your Equipment

Here’s the information you won’t find on a generic Unilock page. In Sacramento’s Natomas basin, behind the levees and inside FEMA Special Flood Hazard Areas, Unilock paver driveways and patios must be installed with permeable base designs and elevated perimeters that allow floodwater to drain without washing out the setting bed. This is a requirement that coastal California contractors rarely encounter, because coastal cities don’t sit behind levee systems with groundwater pressure pushing up from saturated soils. When floodwater rises, a standard compacted-base Unilock installation in Natomas can lose its setting bed in days, leaving pavers floating and misaligned. We design for that from day one: open-graded aggregate layers, geotextile separation, and edge restraints rated for hydrostatic pressure. It’s not a premium upgrade here; it’s the only responsible way to build.

Our crew rebuilt a 1980s Arden-Arcade ranch home’s front walkway after years of differential settling had cracked and heaved the original Unilock Brussels Block pavers. We excavated the expansive clay, installed a geotextile-separated aggregate base, and re-laid the same pavers with fresh edge restraints. The result corrected a 3-inch grade drop near the street without replacing the whole system. That’s the kind of repair that only makes sense when you understand what’s happening under the surface.

Unilock Models & Products We Service in Sacramento

We work with Unilock’s core residential lines, including Brussels Block, Courtstone, Richcliff, and Town Hall. Brussels Block is the classic tumbled-edge paver we see most often on Sacramento driveways and walkways, especially in Midtown and East Sacramento. Courtstone and Richcliff are popular for patios and pool decks, where the larger format reads more contemporary. Town Hall shows up frequently on South Sacramento ranch homes, where the clean linear profile fits the mid-century aesthetic.

For repairs, we use genuine Unilock replacement pavers whenever possible. Color and texture match on an existing installation depends on using the same product from the same manufacturing run when available, and older Unilock pavers often have a distinctive patina that aftermarket products can’t replicate. We stock common Unilock replacement units locally for faster Sacramento turnaround, and we special-order for unusual colors or discontinued lines. Edge restraints and polymeric sand are the exception: we use aftermarket products rated for expansive soil movement, because the original materials often fail first in Sacramento conditions.

FAQs - Unilock Construction in Sacramento

How do I stop my Unilock paver patio from sinking in Sacramento’s clay soil?

The patio is sinking because the base wasn’t built deep enough or compacted enough for Sacramento’s expansive clay, which swells when wet and shrinks when dry. The fix is to excavate the clay, install a geotextile separator, lay a properly compacted aggregate base, and re-lay the pavers with new edge restraints. Patching the surface won’t work if the base has failed. Call (470) 298-9650 for an exact assessment and a written repair quote.

Can you match my existing Unilock pavers if I need a repair in an older neighborhood like Curtis Park?

Yes. We use genuine Unilock replacement pavers whenever possible, and Curtis Park’s pre-war homes often have original installations from specific manufacturing runs. We’ll identify the product line, source matching pavers, and blend them with the existing surface so the repair doesn’t look like a patch. Call (470) 298-9650 and we’ll assess the match before quoting.

Do I need a permit to replace a driveway with Unilock pavers in Land Park?

In most cases, yes. Sacramento requires permits for driveway replacement when the work affects the public right-of-way or changes the grade, and Land Park’s Heritage Tree Ordinance can add an arborist review if a protected tree’s root zone is impacted. We handle the permit process and the tree review as part of the written scope. Call (470) 298-9650 for a site assessment and permit estimate.

Why is my Unilock paver patio covered in a white chalky film after a dry summer?

That’s efflorescence, a mineral salt deposit left when Sacramento’s hard water evaporates from the paver surface during the dry season. It’s cosmetic, not structural, but it indicates the pavers have absorbed mineral-rich moisture. We clean and reseal to prevent recurrence, and we’ll tell you if the pavers need replacement instead. Call (470) 298-9650 for a surface assessment.

How long do Unilock paver driveways last in Natomas’s flood-prone soil?

A properly built Unilock driveway in Natomas, with a permeable base designed for flood conditions, should last 25 to 30 years before needing major base work. A standard installation over compacted soil may fail in 10 to 15 years due to floodwater saturation and soil movement. The base design matters more than the paver brand. Call (470) 298-9650 for a flood-zone-specific quote.
