Unilock Construction in Cedar Park, TX | Penhallow Remodeling Austin
Unilock construction service in Cedar Park, TX covers paver patios, driveways, walkways, and retaining walls built with Unilock’s concrete product lines. As a General Contractor in Cedar Park, Penhallow Remodeling Austin is an independent contractor, not a manufacturer-authorized dealer, which means we repair and rebuild Unilock installations without steering you toward a full tear-out when a color-matched patch or base correction will do. What makes our Unilock work different in Cedar Park is straightforward: we’ve spent over a decade rebuilding installations that failed because the original base never accounted for this city’s expansive black clay. Call (325) 225-5429 for a written estimate before any work starts.
We handle Unilock sales & service across the Austin metro, and Cedar Park keeps us busy for a reason. Most of the homes here were built from the 1990s forward, which means the original hardscaping, patios, and driveways are now hitting the age where bad base prep finally shows itself. We know Unilock Brussels Block, Umbriano, Lineo, and Town Hall the way a good mechanic knows a particular engine: what fails, when it fails, and what actually fixes it.
Why Cedar Park Residents Choose Us for Unilock Service
The short version: we write down the price before we touch your pavers, and we stand behind the work for a full year. Trevor Nash, the owner here at Penhallow Remodeling Austin, came up through Los Angeles Trade-Technical College and spent years on foundation repairs and full kitchen rebuilds before building this company on one idea: give the customer a real number on day one, then do exactly what you said you’d do. That’s the Kingswell Way, and it’s been our operating standard since 2004.
In Cedar Park specifically, we know what the HOA expects, we know which neighborhoods sit on the worst clay, and we know that a paver patio that looks flat in January might be heaving by April. Our techs are background-checked and uniformed, and a real person answers the phone 24/7. When you call about a sinking paver driveway or a retaining wall pulling away from a sloped lot, you’re talking to someone who has fixed that exact problem twenty times within ten miles of you.

Common Unilock Construction Problems We Solve in Cedar Park
- Clay soil heave under paver driveways causing uneven settling and edge spalling. This is the big one in Cedar Park, especially in Ranch at Brushy Creek and other master-planned communities built on reactive black clay. When the soil swells after spring rains and shrinks in August heat, paver edges crack and spall. The fix is rarely just adding sand, it’s rebuilding the base with compacted limestone and geogrid stabilization so the whole surface moves as one unit instead of buckling at the edges.
- Polymeric sand joint washout after flash-flood rain events. Cedar Park gets hit with fast, intense storms that dump water faster than the ground can absorb it. If your paver patio sits even slightly below grade, that water channels through every joint and flushes the polymeric sand right out. We see loose, shifting pavers all over Cedar Park after a heavy rain. We re-sand with fresh polymeric product and, more importantly, correct the drainage so the water has somewhere to go besides through your joints.
- Efflorescence bloom on dark Unilock Brussels Block in shaded HOAs with constant irrigation overspray. That white, chalky film on dark pavers isn’t a defect, it’s mineral salts wicking up through the concrete. In established Cedar Park neighborhoods with mature tree canopy and sprinkler systems hitting the same pavers every morning, it’s everywhere. We clean it and, where practical, adjust the irrigation pattern so you’re not re-blooming the surface every week.
- Cracked retaining wall blocks from hydrostatic pressure on sloped lots backing to Brushy Creek greenbelts. Water builds up behind retaining walls on Cedar Park’s sloped lots and pushes outward. A wall that wasn’t built with proper drainage behind it will crack, usually within the first three to five years. We rebuild with drainage stone, perforated pipe, and Unilock wall units rated for the load.
- Patio paver settlement along foundation lines due to backfill compaction failure. When tract homes went up fast in the 1990s and 2000s across Cedar Park, the soil around foundations often wasn’t compacted properly. Patios laid over that backfill zone sink unevenly, and you get a visible dip right where the patio meets the house. We remove the pavers, re-compact the subgrade, and re-lay the surface so it stays put.
Unilock Service in Cedar Park: What Local Conditions Mean for Your Equipment
Here’s a fact that matters more than any Unilock brochure: Cedar Park’s Buttercup Creek neighborhood sits on some of the most reactive Houston Black clay in the metro area. A 20-foot Unilock paver patio on that soil can heave up to two inches between a dry summer and a wet spring. That’s not a guess; that’s what we measure when we come out with a level and a straightedge. Georgetown and Round Rock don’t have the same clay concentration, and Austin’s older central neighborhoods sit on shallower soils. A paver installation that survives in Georgetown can shift noticeably in Buttercup Creek within a single wet-dry cycle if the base wasn’t engineered for that movement.
Our techs replaced a failed Unilock paver driveway on Buttercup Creek Boulevard where the original base had only two inches of sand over bare clay. After augering down 12 inches, we installed a geogrid-stabilized, compacted limestone base, then re-laid the owner’s salvaged Umbriano pavers with new edge restraints and polymeric sand. The driveway has stayed flat through two wet-dry cycles, and the HOA approved the color match. That’s the difference between putting pavers on the ground and building a surface that holds up under Cedar Park conditions.
Unilock Models & Products We Service in Cedar Park
We work on the full Unilock product range you see across Cedar Park homes: Brussels Block, Umbriano, Lineo, and Town Hall are the lines we service most often. For repairs, we use OEM Unilock pavers and jointing products to guarantee a color and texture match, especially on older installations where Unilock has changed a finish or discontinued a color. When we rebuild a base, we spec high-density aggregates that meet or exceed ASTM strength standards, and for edge restraints we use aftermarket alloys and PVC that outperform the original plastic in expansive soil. That’s a deliberate choice: the factory edge restraint fails in Cedar Park clay. Ours doesn’t.
For kitchens and bathrooms that sit on the same unstable soil, our crews also handle cabinet installation, countertop replacement, and Cedar Park service area remodel work from slab to finish.

What moves those numbers in Cedar Park? Base depth is the biggest factor. A patio on relatively stable ground in Cedar Park Towncenter might need an 8-inch base. The same patio in Buttercup Creek on Houston Black clay may need 12 inches plus geogrid, and that’s real labor and material cost. A paver driveway at the top of the range generally means a larger footprint, deeper excavation, or a substrate that needs significant correction. Every estimate we give is a written line-item price, not a verbal range, and it includes exactly what we’ll do and what it will cost.

FAQs – Unilock Construction in Cedar Park
That sinking is almost always backfill settlement, not paver failure. In Cedar Park’s tract-home developments from the 1990s and 2000s, the soil excavated for the foundation was pushed back in around the slab without proper compaction. Over years of wet-dry cycles, that loose backfill settles, and your pavers sink with it. The fix is to lift the pavers, excavate down to undisturbed soil, re-compact the subgrade in lifts, then rebuild the base. We do this regularly across Cedar Park, and the repair holds because we address the soil, not just the surface. Call (325) 225-5429 if you want a written assessment.
In most cases, yes. Unilock has shifted and renamed colors over the years, but we can often source the matching pavers through our supplier network, even for lines from the early 2000s. When an exact match isn’t available, we pull less-weathered pavers from an edge or under a planter and re-lay the patch so the color difference reads as natural variation, not a visible repair. We’ll tell you plainly if a match is possible before you spend anything.
Yes, in most Cedar Park communities you do. Master-planned neighborhoods like Ranch at Brushy Creek and Buttercup Creek have architectural review committees that govern hardscape materials, colors, and even border patterns. We help you with the application by providing material swatches, a plan sketch, and the spec details the committee wants to see. We’ve worked with enough Cedar Park HOAs to know what triggers a rejection, and we design the plan to pass on the first submission. We also offer our Bathroom Remodeling in Cedar Park with the same HOA-ready planning process.
The answer is never “just add more sand.” Polymeric sand washes out in Cedar Park because water moves through your paver joints faster than it can drain, usually due to a flat grade, a low spot, or a clogged drain. We correct the pitch, install or clear drainage, and then re-sand with the right polymeric product for the joint width. If the water can’t sheet off the surface, no jointing sand will last. We’ll show you exactly where the water is pooling and what it takes to fix it.
If the wall is cracked and leaning, a rebuild is almost always the better value. A cracked block on the face can be replaced, but cracks that come with leaning mean the wall has already lost structural integrity, typically from hydrostatic pressure behind it. We rebuild with proper drainage stone, a perforated pipe, and Unilock wall blocks sized for the load. It costs more than a patch now, but a patch on a failed wall in Cedar Park clay will crack again within a season or two. Call (325) 225-5429 for a straight answer and a written price.
