Unilock Construction in Westminster, CA | Square Deal Contractors
Square Deal Contractors provides independent Unilock paver and retaining wall installation, repair, and replacement across Westminster’s 92683, 92684, and 92685 ZIP codes, and also serves nearby areas with Unilock in Midway City. We’re not manufacturer-authorized, and we don’t pretend to be. What we are is a general contractor that’s spent years watching how Unilock’s segmental systems hold up on Westminster’s specific mix of clay subgrade, settling 1950s – 70s tract slabs, and Santa Ana wind exposure. If your paver driveway off Bolsa Avenue is rutting or your side-yard patio near Little Saigon is washing out, call (866) 623-7205 and we’ll give you a straight answer.
Why Westminster Residents Choose Us for Unilock Service
Most hardscape crews in Westminster can lay pavers. Far fewer can tell you why a Brussels Block driveway failed three years after install, or whether that Sierra Stone wall needs a drain retrofit before it gets worse. We can, because we’ve torn out enough failed bases and rebuilt enough edges to know exactly how Unilock products behave on Westminster’s soils. Nolan Breckett, our owner, grew up in Lake Forest and learned construction fundamentals through Saddleback College’s construction technology program. That background shows up in how we sequence hardscape work: utility locating before excavation, base compaction in lifts, drainage addressed before the first paver goes down. Our Unilock sales & service work spans the full scope, from driveway rebuilds to patio and seat wall integration.

Common Unilock Construction Problems We Solve in Westminster
- Rutting and lippage on Brussels Block driveways. When the original clay subgrade under a 1960s tract driveway isn’t fully re-excavated, winter rains saturate the soil and the base shifts. We see this most on the older streets west of Beach Boulevard, where decades-old clay hasn’t been touched since the house went up. The pavers drop, edges lip, and puddles form. Fix is a full re-excavation to a compacted aggregate base, not a patch job.
- Polymeric sand washout on sloped commercial aprons. Bolsa Avenue strip-center parking aprons catch Santa Ana wind-driven debris, and once the joint sand erodes, weeds follow. We re-sand with a quality aftermarket polymer and reset edge restraints so the slope drains instead of flushing the joints every storm.
- Efflorescence and spalling on older Sierra Stone walls. When original drainage wasn’t tied into the property’s clay sewer footprint, water sits behind the wall, salts bloom through the face units, and the surface starts to flake. We add proper drainage aggregate and weep points, then replace the damaged units with genuine Unilock stock so color stays consistent.
- Edge restraint heave on shallow foundations. Westminster’s 1960s – 70s tract driveways frequently sit on thin, settling slabs. Without a solid edge restraint anchored below grade, the outside courses of pavers spread and heave within a couple of seasons. We reset restraints at proper depth and re-compact the base before relaying the field.
- Side-yard patio settlement over old utility trenches. When a patio goes over ground that was trenched decades ago for clay sewer laterals, differential settlement is almost guaranteed. We probe and mark utilities first, then over-excavate problem areas before compacting fresh aggregate.
Unilock Service in Westminster: What Local Conditions Mean for Your Equipment
Westminster’s Little Saigon households frequently want side-yard paver patios and open-air cooking areas built for multigenerational gatherings, similar to the projects we handle with Unilock in Garden Grove. That’s not a generic backyard patio request. These side yards are narrow, they carry real foot traffic during weekend family cookouts, and many of the lots still have their original clay sewer laterals running beneath them. Clay pipe from the 1960s is brittle and shallow, and an excavator bucket doesn’t care how old it is. Before we dig any Unilock base in these neighborhoods, we probe the ground and mark every utility line we can identify. It’s slow, careful work, and it’s the reason we don’t hit what we can’t see. Know what you’re getting into before the first nail goes in, and before the first shovel breaks ground, too.
Unilock Models & Products We Service in Westminster
We work with the Unilock lines most common on Westminster properties: Brussels Block, Uni-Stone, Beacon Hill, and Sierra Stone. For visible hardscape, we source genuine Unilock units and matching accessories so color and profile stay consistent from patch to field. For base aggregate, edge restraints, and polymeric sand, we use quality aftermarket materials where performance matters more than a logo on a bag. That’s the honest split, and we’ll tell you exactly why. Structural base failure isn’t a parts problem, it’s an engineering problem, and we’ll tell owners when re-laying over the old subgrade is throwing money away versus a full rebuild.

FAQs – Unilock Construction in Westminster
Most residential paver driveway replacements in Westminster don’t require a building permit so long as the footprint and drainage pattern aren’t changing. But if we’re adding a retaining wall over three feet, altering grade, or tying into the public right-of-way, the City of Westminster will want plans and an inspection. We handle that. If your project needs permits, we pull them and call for the inspections. Call (866) 623-7205 and we’ll tell you whether your specific job triggers a permit before you spend a dollar.
Sinking and heaving almost always trace back to the base, not the pavers. Westminster’s 1950s – 70s tract homes were often built on shallow foundations and untouched clay subgrade. When a paver driveway goes over that without deep re-excavation and proper compaction, winter moisture and seismic settling do the rest. We see it constantly on the older streets west of Beach Boulevard. Pavers don’t fail on their own; bad preparation fails them.
Yes, but not carelessly. Westminster’s Little Saigon side yards often hide original clay sewer laterals from the 1960s, and those pipes are brittle and shallow. We probe and mark utilities before any excavation, and we can build a patio over a lateral if the line is in decent shape and we lay a properly compacted base above it. If the clay is already deteriorating, the smarter move is replacing or lining the line first. We’ll tell you which situation you’re in.
For driveways in Westminster, Brussels Block handles our winter rains well when the base is done right, and its color hides the fine dust Santa Ana winds leave behind. For walls, Sierra Stone has the mass to stand up to wind-driven debris, but only if drainage behind the wall is correct. No Unilock product overcomes a bad base or missing drainage. Ask us and we’ll show you what’s actually on Westminster driveways and which ones are still flat five years later, including work we’ve done with Unilock service in Huntington Beach.
Sometimes, over the life of the driveway, yes. Patching a heaved Brussels Block driveway on a failed base costs less today, but you’ll pay again in two seasons when the same area shifts. We quote both options honestly, and when re-laying over the old subgrade is a waste, we’ll say so. Call (866) 623-7205 and we’ll give you numbers for both a patch and a proper rebuild.

On a 1960s tract home off Bolsa Avenue, our crew pulled up a heaved Brussels Block driveway laid over the original settling slab, re-excavated to a compacted aggregate base, reset the edge restraint, and reinstalled with fresh polymeric sand. We tied a Sierra Stone seat wall into the new side-yard patio for the family’s outdoor cooking setup, and the owner finally had a driveway that drained instead of puddling after winter storms. That’s the work we do in Westminster. Call (866) 623-7205 to schedule your free estimate.
