We’ve worked with Unilock in Sherman Oaks long enough to know how their hardscapes behave in our local conditions. The valley’s expansive clay soils, summer heat that regularly pushes past 100°F, and winter rain patterns that concentrate in January and February all stress paver installations differently than coastal climates do. Our crews have rebuilt Unilock driveways near the Galleria corridor and installed Beacon Hill patios on hillside parcels off Ventura Boulevard where drainage and slope stability are genuine engineering concerns, not afterthoughts.

We are not affiliated with, authorized by, or endorsed by Unilock. We are an independent construction firm that sources genuine Unilock replacement materials when available and uses matching-quality alternatives when a specific color or texture has been discontinued. Our expertise comes from field hours, not a manufacturer’s certificate.

Why Trust Rowan Construction Group Sherman Oaks for Your Unilock Construction?

Grant Rowan, our owner, studied construction technology at Los Angeles Valley College in Valley Glen before he ever ran a paid crew. That formal training in reading structural drawings shows up in how we approach Unilock work. We don’t guess at base depth or drainage slope. We measure, specify, and document.

Our technicians are background-checked and uniformed, and every visit produces a documented photo record that the homeowner receives. Not as an upgrade. As standard. When we quote a Unilock paver driveway replacement in Sherman Oaks, the price is flat, written, and includes the full scope: demolition, base preparation in compacted lifts, bedding layer, paver installation, edge restraint, polymeric sand, and compaction. Under Clause 1 of the Haven Standard, that written price is delivered before any work starts. No exceptions.

We’ve kept projects within a few percent of the agreed cost across 4,000-plus jobs since 2007. The discipline is simple: no change proceeds without a signed change order. A homeowner who wants to widen a Unilock patio mid-project gets a written amendment with a precise dollar amount, signs it, and only then do we order additional Beacon Hill pavers. This is the administrative practice Haven acquired Rowan for, and it protects both parties from the surprise invoices that plague this industry.

Grant still walks sites regularly. He can tell when a subbase isn’t sitting right by feel, and he’s particular about edge restraint alignment on Unilock installations because that’s where driveways fail first under the turning radius of SUVs common in Unilock in Van Nuys and Sherman Oaks garages.

Common Unilock Construction Problems We Fix in Sherman Oaks

• Efflorescence bloom on Brussels Block and Cambridge pavers after winter rains. The white, chalky film that appears in January and February is calcium hydroxide migrating to the surface as moisture moves through the concrete. It is not failed sealer, and it does not mean your pavers are defective. In Sherman Oaks, where winter rains are concentrated and followed by dry heat, efflorescence typically resolves after one or two wet-dry cycles. We distinguish this normal condition from spalling or freeze damage, which are genuine failures requiring replacement. Power washing too aggressively can drive salts deeper and make the bloom recur.
• Edge chipping and joint sand loss on Beacon Hill pavers from vehicle tracking. Beacon Hill’s tumbled surface and beveled edges look excellent but are vulnerable at driveway margins where tires repeatedly scrub. The 1960s ranch homes common in Sherman Oaks often have narrow driveways with tight turning radii, amplifying this wear pattern. We address it with concrete edge restraints set in a haunch rather than plastic spikes, and we specify polymeric sand with a higher resin content for these high-shear zones.
• Base settlement and paver lippage on sloped driveways. Sherman Oaks hillside properties above the 405/101 interchange present cut-and-fill grading that moves seasonally. When the aggregate base is not installed in lifts with plate compaction between each, pavers settle differentially and create trip hazards. We’ve rebuilt installations where the original contractor dumped six inches of base and compacted once. Our spec calls for lifts no thicker than four inches, compacted to 98% Proctor density, with geotextile separation on native soils with high clay content.
• Retaining wall block cracking or bowing from hydrostatic pressure. Unilock Estate Wall and similar segmental retaining walls fail when drainage is omitted. Sherman Oaks’ winter rains saturate backfill, and without weep holes, drainage swales, or a perforated pipe behind the wall, hydrostatic pressure builds until blocks crack or the wall leans. We inspect for these conditions during our initial site visit and specify drainage remediation as a separate line item when it’s missing. A wall without drainage cannot be patched; it must be rebuilt with proper water management.
• Color mismatch in repairs where original pavers have weathered. Unilock’s color-through manufacturing holds up well, but UV exposure and traffic polish surface texture over years. A new Brussels Block paver dropped into a five-year driveway reads as a patch. We source from multiple production lots when possible, and we counsel homeowners that strategic paver redistribution - removing weathered units from less visible areas for the repair zone - often produces a better result than a single obvious replacement.

Unilock Parts & Our Repair-vs-Replace Approach

For Unilock repairs, we source genuine replacement pavers and wall blocks when the exact color and texture remain in production. Unilock runs multiple manufacturing facilities, and color drift between lots is real. When we cannot match the original, we use equivalent-quality products from Belgard or Techo-Bloc with comparable compressive strength and absorption specs, disclosed in writing before work proceeds.

Our repair-versus-replace decision is straightforward. Isolated cracked pavers or localized joint erosion? We swap units and repoint. Widespread settlement exceeding three-eighths inch of lippage, or base contamination from tree root intrusion or broken irrigation? The affected area gets rebuilt. Patching over a failed base is a temporary fix that costs more in the long run, and we don’t quote them. Our written scope specifies which approach applies to each zone of your project.

We stock polymeric sand, concrete edge restraints, and geotextile fabric locally for fast turnaround on Unilock service in Encino and Sherman Oaks repairs. For full installations, Unilock pavers typically deliver within two weeks from regional distribution. Call (213) 221-0788 and we’ll confirm current lead times for your specific product.

Our Unilock Service Process - Step by Step

1. 1
   Diagnosis with photo documentation. We arrive, inspect the Unilock installation, and photograph every condition we find: lippage measurements, efflorescence patterns, wall lean angles, drainage presence or absence. You receive these photos with our written findings before any quote is prepared.
2. 2
   Written flat-price quote. Under Clause 1 of the Haven Standard, we deliver a written price with line-item scope before any work starts. For Unilock projects, this specifies paver model, color, quantity, base depth and compaction method, edge restraint type, and joint sand specification.
3. 3
   Repair or installation with signed change-order discipline. If site conditions reveal something our initial inspection couldn’t access - a broken drainage pipe beneath a patio, for instance - we stop, document, and present a written change order with exact cost before continuing. No verbal approvals. No surprise invoices.
4. 4
   Compaction and final inspection. We compact Unilock pavers with a plate compactor fitted with a urethane mat to prevent surface damage, sweep in polymeric sand, activate with water per manufacturer spec, and compact again. For walls, we verify batter angle, drainage function, and cap unit adhesion.
5. 5
   Warranty documentation and photo record. You receive a written warranty, the final photo record of completed work, and our 365-Day Done Right Promise: if it’s not done right, we make it right. The terms are printed, not implied.

Unilock Products We Service & Install in Sherman Oaks

We work with the full Unilock residential line: Brussels Block for traditional driveway and patio surfaces; Beacon Hill for tumbled, naturalistic finishes; Cambridge for cobblestone-pattern applications; and Estate Wall for retaining and freestanding wall systems. We also handle Unilock’s permeable paver options where stormwater management is required by Los Angeles County code on certain hillside or large-impervious-area projects.

For Sherman Oaks’ high-fire-hazard zones above the 405/101 interchange, we specify hardscape materials with appropriate non-combustible ratings as part of defensible-space planning. Unilock concrete pavers qualify, and we document this for permit applications when required by LAMC fire-resistant assembly codes.

We Also Service These Brands

Our sourcing depth runs past Unilock to KraftMaid and Wellborn cabinetry, Cambria and Silestone surfacing, Kohler and Toto fixtures, GAF and Owens Corning roofing, and Belgard and Techo-Bloc pavers. This range matters because many Sherman Oaks projects combine trades - a Kitchen Remodeling project with a paver patio extension, or a bathroom renovation with retaining wall work for hillside access. One written quote, one accountability point, no subcontractor finger-pointing.

FAQs - Unilock Construction Service in Sherman Oaks

Is Rowan Construction Group Sherman Oaks authorized by Unilock? No. We are an independent construction firm with no manufacturer authorization, endorsement, or warranty partnership with Unilock. We source genuine Unilock products through standard distribution channels and install them according to ICPI (Interlocking Concrete Pavement Institute) standards, which govern proper base preparation, edge restraint, and joint sand specification.

Why does my Unilock Brussels Block driveway look white and chalky after the rainy season? That is efflorescence, a natural migration of mineral salts to the paver surface as moisture moves through the concrete. In Sherman Oaks, where winter rains concentrate and summer heat follows, it typically resolves without intervention. If it persists beyond two cycles or appears powdery and loose rather than crystalline, call (213) 221-0788 and we’ll inspect to rule out spalling or sealer failure.

Can you match my existing Unilock Beacon Hill pavers for a repair in Sherman Oaks? We can if the exact color and production lot remain available. Unilock discontinues some colors, and weathering changes surface appearance over time. We source multiple lots when possible and may recommend redistributing weathered pavers from less visible areas to blend the repair zone. We’ll show you samples before any order is placed.

What causes Unilock pavers to sink or become uneven on Sherman Oaks driveways? Base failure from inadequate compaction, insufficient depth, or organic soil contamination. Our valley’s expansive clay soils swell and shrink with moisture changes, stressing improperly prepared bases. Hillside properties add slope-stability challenges. We diagnose the cause before quoting, because the fix differs: localized re-compaction for minor settlement, full rebuild for widespread base failure. Call (213) 221-0788 for a free inspection and written quote.

Is polymeric sand the best choice for Unilock patio joints in this area? Yes, with qualifications. Polymeric sand resists washout better than traditional joint sand in Sherman Oaks’ concentrated winter rains, and it inhibits weed growth. We specify higher-resin formulations for high-traffic or vehicle-bearing areas like driveway edges. It is not appropriate for joints wider than one-quarter inch, where we use a different product and disclose this in the written scope.

Do you need to remove all my Unilock pavers to fix a retaining wall that is bowing? Often yes, if the bowing stems from hydrostatic pressure behind the wall. The drainage system - perforated pipe, gravel backfill, weep holes - must be installed or restored, which requires access to the wall’s back face. We may be able to stabilize a minor lean with tie-backs in limited cases, but we don’t quote structural patches that conceal ongoing water pressure. The written scope will specify exactly what comes out and what goes back.

We recently rebuilt a Sherman Oaks driveway where a previous Unilock Brussels Block installation had settled and was holding water against the garage. Our crew removed the affected pavers, corrected the slope, re-compacted the base in lifts, and reinstalled the Brussels Block with fresh edge restraints and polymeric sand. The homeowner now has a driveway that sheds water properly and no longer trips on lippage. Measure twice, write it down, then build it.

Call (213) 221-0788 to schedule your free estimate. We’ll inspect your Unilock installation, document conditions with photos, and deliver a written flat price before any work begins. The 365-Day Done Right Promise applies to every job we take.
