Unilock Construction in Austin, TX | Penhallow Remodeling Austin
Unilock paver driveways, patios, and walkways in Austin need a contractor who understands two things at once: how Unilock products are built, and how Central Texas clay, sun, and water rules try to tear them apart. We’re Penhallow Remodeling Austin, Unilock specialists and an independent service provider, and we handle both halves of that equation every week. Our crews diagnose base failure, edge restraint problems, joint sand loss, and surface wear across Austin’s older slab-on-grade ranches and newer Hill Country builds alike. Call (325) 225-5429 for a free estimate on any Unilock repair or new installation.
Why Austin Residents Choose Us for Unilock Service
Trevor Nash founded Penhallow Remodeling, a General Contractor in Austin, on a simple arrangement: tell you what the work costs before we start, and stand behind it after we leave. That’s not a slogan around here. It’s how we run every Unilock job, from a single paver reset in Brentwood to a full driveway replacement in Allandale. Trevor learned construction fundamentals at Los Angeles Trade-Technical College and has spent well over a decade serving Austin homeowners, so when he talks about expansive clay or UV-stable joint sand, it’s because he’s watched both fail on real Austin job sites, not because he read a brochure.
We’re an independent Unilock service provider. That means we source genuine Unilock pavers from the manufacturer’s regional distributors in Central Texas, but we don’t claim any factory authorization. What we claim is simpler: we show up when we said we would, we give you a written price before any work begins, and every repair carries our 365-Day Done Right Promise in writing. If something fails inside that year, we come back and fix it at no charge. Background-checked, uniformed technicians handle every visit, and a live person answers our phone 24/7. You can reach us at (325) 225-5429.

Common Unilock Construction Problems We Solve in Austin
- Edge restraint failure on paver borders. Austin’s drought-to-flood cycles make expansive clay soil heave and contract, and a plastic or aluminum edge restraint that would hold fine in stable soil gets pushed outward here. We see this constantly on Brussels Block driveways in neighborhoods like Cherrywood, where pavers along the border start spreading and the clean line of the driveway turns wavy within a few seasons. The fix starts with excavating the border, resetting the restraint with longer spikes, and re-compacting the base before relaying pavers.
- Joint sand erosion from heavy rain runoff. Sloped Austin lots, especially in the hills west of MoPac, send serious water across paved surfaces during storms. When joint sand washes out from between Courtstone pavers, the individual units lose the friction that locks them together, and the first vehicle that rolls over them shifts the whole field. We re-sweep and re-compact polymeric sand after any repair, but on steep grades we often recommend a different joint compound that holds up better under repeated sheet flow.
- Surface efflorescence and UV fading. White, chalky mineral deposits on Richcliff paver faces are common in western Austin, where full afternoon sun and high heat pull moisture through the paver and leave salts behind. Add Austin’s intense UV exposure and colored pavers that looked rich on day one can look washed out after three or four summers. We clean efflorescence with the right paver-safe products and can discuss sealers that slow UV degradation without trapping moisture, which would create a different problem entirely.
- Base settlement under walkways on poorly drained sites. In the Save Our Springs jurisdiction and other areas with drainage restrictions, a Unilock walkway installed over a standard compacted base can become a series of dips and tripping hazards once water finds a path underneath. The aggregate base washes out, the pavers drop, and you’re left with a wavy surface. We excavate, install a geotextile fabric, and rebuild the base in lifts with proper compaction so water moves around the installation rather than through it.
- Discontinued color matching. Unilock changes and retires color lines over time, and Austin homeowners with a 15-year-old Beacon Hill Flagstone patio often can’t find the exact shade anymore when a section needs replacement. We salvage undamaged pavers from the existing installation first, then source the closest available match from regional distributors. If the only option is a different color, we’ll tell you that plainly and show you samples before anything gets installed.
Unilock Service in Austin: What Local Conditions Mean for Your Equipment
Here’s the piece most paver pages won’t tell you about Austin. In the Save Our Springs watershed, a Unilock paver driveway or patio is only treated as a pervious surface if it’s installed over an engineered open-graded base with no fines. Otherwise, the city counts it the same as impervious concrete for site coverage limits. That single rule changes everything about how we design Unilock hardscapes in the Barton Springs Zone. We regularly have to adjust base design, swap the aggregate mix, and get water-quality sign-off before adding a Unilock driveway or patio on properties in that area. It’s not a paperwork annoyance. It determines whether your installation passes inspection and whether your lot drains the way it’s supposed to. Our crew replaced a 1980s concrete driveway in the Allandale neighborhood with a Unilock Courtstone paver driveway after clay soil movement cracked the original slab and created a drainage slope toward the foundation. We excavated 12 inches, installed a geotextile and TXDOT flex base, then used a plate compactor in phases to prevent future settlement. After paver installation, we sealed the joints with polymeric sand and reset the edge restraint. The finished driveway sheds water away from the home and has held level through two record rain events. That’s the difference between knowing pavers and knowing Austin.
Unilock Models & Products We Service in Austin
We install and repair the full Unilock lineup you’re most likely to see on Austin properties: Brussels Block, Courtstone, Richcliff, and Beacon Hill Flagstone. Each one behaves differently in Central Texas. Brussels Block’s tumbled edges hide minor shifting, which helps on clay-heavy lots. Courtstone’s clean lines show misalignment immediately, so edge restraint and joint sand matter more. Richcliff’s larger face format looks great on patios but absorbs more heat in full sun. Beacon Hill Flagstone’s varied surface means repairs need careful color matching. For parts, we stock common joint sand and edge restraint components locally for fast Austin turnaround. Genuine Unilock pavers come from the manufacturer’s regional distributors in Central Texas, so color and dimensional match are as close as you can get without pulling pavers from your own existing installation. When a color is discontinued, we salvage first and match second, and only with your approval.

What drives the number up or down on an Austin Unilock job: how much excavation and base rebuild your site needs, whether drainage corrections are required, how accessible the area is for equipment, and which paver line you choose. A flat backyard patio over stable ground costs far less than a sloped driveway that needs 12 inches of excavation and a new aggregate base. Every free estimate includes a written, line-item price so you know exactly what each part of the work costs before we start. Tell me what you need, I’ll tell you what it costs, and we’ll go from there. Call (325) 225-5429 and we’ll schedule a time to walk the site with you.

FAQs – Unilock Construction in Austin
Are you an authorized Unilock dealer or contractor? No. We are an independent Unilock service provider. We install and repair Unilock products using the manufacturer’s published installation specs and source genuine Unilock pavers from regional distributors, but we don’t hold any factory authorization or dealership status. That independence means our recommendations on repair versus replacement are based on what’s best for your property, not on moving inventory.
Do you use genuine Unilock pavers or aftermarket copies? We source genuine Unilock pavers from the manufacturer’s Central Texas distributors whenever adding to or repairing an existing installation. For discontinued Unilock colors, we salvage undamaged pavers from your existing layout first. If that doesn’t yield enough material, we show you a matching option before anything gets installed. No aftermarket parts go into your job without your sign-off.
How long does Unilock paver repair take in Austin? Most edge restraint and joint sand repairs finish in one day. Base settlement repairs that require excavation and re-compaction typically run two to three days depending on access and drainage conditions. A full driveway replacement can take five to seven working days. We’ll give you a written timeline with your estimate, and the arrival window we set is the arrival window we keep.
Which Unilock models do you service in Austin? We work on Brussels Block, Courtstone, Richcliff, and Beacon Hill Flagstone as our primary coverage, but we’re happy to quote repairs on other Unilock lines you already have installed. Bring us a photo of the paver and the area in question, and we’ll identify what you’re working with and whether we can match it.
How do I stop weeds from growing between my Unilock pavers without damaging the Austin water supply? The short answer is polymeric sand, not herbicide. Weeds establish in joint sand that’s been washed out by rain, so the first step is removing existing weeds by hand or with a paver-safe tool, then re-sweeping fresh polymeric sand into the joints and activating it with water. Once cured, the polymer binds the sand and blocks new weed growth without introducing chemicals that run off into Austin’s creeks and the Edwards Aquifer recharge zone. That matters in every part of Austin, but especially in the Save Our Springs watershed. Call (325) 225-5429 and we’ll assess whether your joints need a full re-sand or just touch-up work.
