Unilock Construction in Garden Grove, CA | Alder Contractors
We’re Alder Contractors, and we provide independent Unilock paver installation and repair across Garden Grove, CA. We’re not manufacturer-authorized or affiliated with Unilock, and that’s exactly what makes our work here different: we build paver driveways, patios, and walkways to Unilock’s own installation specifications, but our recommendations come from walking your lot, reading your grade, and knowing what Garden Grove’s 1950s and 60s tract homes actually need. Call (833) 467-7020 for a free estimate.
Why Garden Grove Residents Choose Us for Unilock Service
Nelson Ibarra, our owner here at Alder Contractors, grew up in the Inland Empire and has spent the better part of three decades on job sites that taught him one thing: the base is never the place to cut corners. He picked up his construction fundamentals at Chaffey College in Rancho Cucamonga, working hands-on with building technology while his father, a drywall finisher, had already dragged him to weekend job sites years prior. That grounding shows up in every Unilock field we set in Garden Grove.
We work from Unilock sales & service specs, not a dealer counter. When a Garden Grove homeowner asks us to re-face a cracked 1960s driveway or build a paver patio behind a new rear addition, we’re looking at what the soil, slope, and original pour actually demand. Because we’re independent, our answer is never about moving a particular SKU. It’s about whether the base has to come out, whether the edge restraint will hold at a tight property line, and whether the grade still sheds water away from the house.
As a whole-home contractor, we bring something a standalone paver installer can’t: when your patio job reveals a drainage problem that traces back to a roofline or a re-graded addition, we can address it under one contract instead of handing you a referral. From the roofline to the backyard, we handle the coordination so you don’t have to.

Common Unilock Construction Problems We Solve in Garden Grove
- Base failure on shallow slab-on-grade lots. Original 1950s and 60s Garden Grove driveways were often poured thin, right over native soil with no aggregate base. Lay a new Unilock field over that old bed and the pavers settle unevenly within a season, joints opening like a cracked smile. We over-excavate and set a proper compacted base before a single paver goes down.
- Joint sand washout and efflorescence from Santa Ana winds. Garden Grove’s late-summer and fall Santa Ana events drive sand right out of open joints on Brussels Block and Cambridge Cobble fields. Add hard local water leaving white efflorescence bloom on the paver face, and homeowners often assume the product is defective. It’s not. It’s joint maintenance and water chemistry, and we correct both.
- Edge restraint kick-out at tight property lines. On 6,000 to 7,000 square foot lots with narrow driveways and detached garages, pavers frequently butt against a neighbor’s line or a block wall with no real edge restraint. The field creeps. The outside course spreads. We rebuild those edges with Unilock’s own restraints, not a strip of plastic that fails in two years.
- Drainage reversals after ADU or addition work. When a rear-yard ADU or addition goes in, the original lot grading toward the street gets disturbed. Pavers that drained fine before suddenly pond, because runoff now sheets toward the house instead of away from it. This is a chronic Garden Grove problem, and it’s one of the first things we check.
- Thin original pours under driveways that no longer carry the load. Multigenerational households who have added living space often find their original driveway is now working harder than it ever did. We see it in the 92843 and 92844 neighborhoods all the time: the old slab has hairline cracks spreading from the garage apron, and the replacement has to be engineered for real weight.
Do it right the first time – the callback always costs more than the extra hour up front.
Unilock Service in Garden Grove: What Local Conditions Mean for Your Equipment
Garden Grove’s Little Saigon corridor in 92843 and 92844 drives some of the heaviest owner-occupied renovation demand in Orange County. Multigenerational households have already added a rear addition or a detached ADU to a 1950s tract lot. That means a large share of our Unilock work is re-facing front yards and driveways where the lot has been re-graded after the original drainage plan was drawn. The paver grade has to be re-tied to a surface that no longer matches the 1950s blueprint. Near Brookhurst Street, we regularly find the original sewer laterals and undersized electrical panels forcing utility upgrades before the first paver permit sign-off, and the new paver field has to be coordinated with those trenching schedules, not installed in isolation. That’s not a generic Unilock problem. It’s a Garden Grove problem, and we’ve solved it enough times to know exactly where the conflicts land.
Unilock Models & Products We Service in Garden Grove
We install and repair the full range of Unilock product lines you’ll find across Garden Grove, including Brussels Block, Cambridge Cobble, Beacon Hill, and the Treo permeable paver. For repairs, we specify Unilock’s own edge restraints, joint sand, and base aggregate rather than generic substitutes, because the paver face is rarely the weak point. The base and the edge are. When a field is structurally sound, we re-sand, re-level, and re-set rather than sell a full replacement. When the old base has to come out, we say so plainly and explain why. If you’re looking at a full driveway or patio, see how Unilock fits into a broader whole-home scope on our Unilock sales & service page.

FAQs – Unilock Construction in Garden Grove
No, not if you want a field that stays flat. Garden Grove’s original driveways were typically poured thin over native soil with no aggregate base, and laying pavers over that is a recipe for settlement within a season. In almost every case on these 1950s and 60s lots, the old slab has to come out and a proper compacted base has to go in first. Call (833) 467-7020 and we’ll tell you honestly what your slab can and can’t carry.
Only if the grade is wrong. When an ADU or addition goes in on a shallow Garden Grove lot, the original drainage toward the street often gets disturbed, and pavers that would have drained fine before start ponding because runoff now sheets toward the house. We re-grade the paver base away from the foundation and tie it to a swale or drain. Done right, it fixes the flooding rather than adding to it. Call (833) 467-7020 for a drainage and grading review before you pour.
Because Garden Grove’s Santa Ana events carry strong, dry gusts that strip loose sand from open paver joints, especially on Brussels Block and Cambridge Cobble fields with wider joints. The fix is a properly compacted polymeric or Unilock-specified joint sand, installed correctly, not a quick sweep of play sand. Once it’s set, it stays through the wind season. Call (833) 467-7020 and we’ll re-sand your joints the right way.
Most paver driveway and patio replacements in Garden Grove are considered routine hardscape work, but if the job involves regrading, drainage changes, or work in the setback, the city may want a look. We handle permits when they’re required and coordinate with the utility upgrades that often come with older Garden Grove lots. Estimates are free, and we’ll tell you exactly what your project triggers before any paperwork starts.
For some lots, yes. Treo’s permeable system lets water pass through the joints into an open-graded base, which helps on shallow lots where drainage is a struggle after an ADU or addition. But Treo isn’t right for every soil condition, and it needs a deeper base than standard pavers. In Garden Grove’s tight lots, we’ll assess your soil and grade before recommending it. Call (833) 467-7020 for a free evaluation.
