Unilock Construction in Bloomington, CA | Square One Builders
Square One Builders provides independent Unilock paver and retaining wall installation and repair across Bloomington’s 92316 ZIP. We work with Unilock product, not for Unilock – no dealer or manufacturer authorization is implied. What makes our Unilock work here different is that we plan for Bloomington’s sandy alluvial soils, county-island permitting, and Cajon Pass wind corridors before we set a single paver. Call (877) 688-9930 for a free estimate.

Why Bloomington Residents Choose Us for Unilock Service
Bloomington’s housing stock leans heavily toward post-war and mid-century ranch homes on generous lots, and those lots often came with owner-built additions, detached shops, and hand-laid hardscape that predates current San Bernardino County code. When a paver driveway starts spreading at the apron or a retaining wall leans into a slope, Bloomington homeowners need a contractor who understands both the Unilock product and the county’s expectations for base depth, drainage, and setback documentation. Brent Calloway, our owner and general contractor, has spent three decades working on homes throughout the Inland Empire, and he started in this trade doing ground-level work – hauling material, reading plans, asking questions until the answer made sense. That instinct against waste of materials and time still drives how we approach every Unilock job in Bloomington, and it’s the same standard we bring to our Unilock repair in Glen Avon.
We’re also Unilock sales & service specialists in the sense that we specify genuine Unilock-compatible pavers, matching edge restraint, and polymeric joint sand so color, thickness, and chamfer match the existing field. Where performance matters more than brand label, we source quality aftermarket base aggregate and geogrid. That’s the honest approach: genuine product where appearance and fit matter, aftermarket where the buried structure does the work.

Common Unilock Construction Problems We Solve in Bloomington
- Base and joint failure from settlement. Bloomington’s sandy alluvial soils and seasonal downpours in the wash areas wash out bedding sand and open joints. Brussels Block and Beacon Hill pavers rock, shift, and grow weeds along driveway and patio edges. We re-grade and compact a proper aggregate base before resetting the field.
- Wind-driven sand abrasion and efflorescence. Santa Ana and Cajon Pass winds blast fine grit across exposed paver fields, scuffing the surface and driving the pale bloom common on Brussels Block and Town Hall faces when moisture migrates through open joints. We clean, re-sand, and seal where the field is still sound; we replace where the surface is worn past saving.
- Edge restraint and soldier-course blowouts. Pavers laid on big rural lots without proper edge restraint or polymeric joint sand creep outward under vehicle load and heat cycling. Soldier courses on driveway aprons separate from the field. We reset the edge with proper restraint and fresh joint sand.
- Retaining wall block creep and drainage failure. Brussels Dimensional Stone walls built against slopes without geogrid and drainage weep relief lean or bulge after heavy rain, especially where downspouts dump onto the wall. We rebuild with proper drainage behind the wall so water never pushes it again.
- Driveway apron rutting from owner-built drainage. We regularly see runoff from older detached shops cutting across Unilock driveways, washing out base material and leaving ruts. We fix the drainage path, not just the pavers on top of it.
Unilock Service in Bloomington: What Local Conditions Mean for Your Equipment
Because Bloomington is an unincorporated county island wedged between Fontana, Rialto, and Colton, most paver driveways, patios, and retaining walls here are permitted through San Bernardino County rather than a city counter. The county wants grading, drainage, and setback detail that a homeowner-built shop or horse-paddock wall often skipped. So before we set a single Unilock paver on a Bloomington lot, we document base depth and drainage. That’s the difference between a patio that holds flat for fifteen years and one that heaves the next wash season. On a deep rural-residential lot off the Bloomington flats, a homeowner’s Brussels Block driveway had heaved and spread at the apron where years of runoff from an owner-built detached shop poured across it. We pulled the field, re-graded and compacted a proper aggregate base, reset the Brussels Block with new edge restraint and polymeric joint sand, then routed the shop downspout to a dry well so the water quits cutting the drive. The owner got a flat, stable apron that handles the summer heat and the wash-season downpours without the old rutting.
Unilock Models & Products We Service in Bloomington
We install and repair the Unilock lines most common on Bloomington’s large-lot ranch properties: Brussels Block tumbled concrete pavers for driveways and walkways, Beacon Hill Flagstone for patios and pool decks, Brussels Dimensional Stone for retaining walls and planter borders, and Town Hall flagstone-style pavers for the wider, formal look. We keep genuine Unilock-compatible edge restraint and polymeric joint sand on hand for fast Bloomington turnaround, and we match color, thickness, and chamfer to existing fields when only part of a driveway or patio needs work. If a paver field is settling over a failed base, we tell owners honestly that re-laying the base is the only real fix – topping sand over trouble just postpones the call back.

FAQs – Unilock Construction in Bloomington
Generally yes. Bloomington is unincorporated county land, so paver driveways, patios, and retaining walls over a certain height or with grading changes are permitted through San Bernardino County rather than a city counter. For an exact answer call (877) 688-9930 – we’ll tell you what the county typically wants for your specific lot.
They will if the base is built right. Sandy alluvial soils drain fast, but they also move under load and wash out in seasonal downpours. A proper compacted aggregate base with edge restraint and polymeric joint sand is the difference between a flat field and one that shifts in a year. We document base depth before we set any paver.
Yes. We match genuine Unilock-compatible pavers by color, thickness, and chamfer to your existing Brussels Block, Beacon Hill, Town Hall, or Brussels Dimensional Stone field. Older pavers may have some fade, but we’ll get as close as the product allows and tell you honestly if a patch will be visible.
Drainage behind the wall and proper base preparation. A Brussels Dimensional Stone wall without geogrid and weep relief will lean or bulge after heavy rain. We rebuild with drainage gravel and weep holes so water pressure never pushes the wall again. Call (877) 688-9930 and we’ll walk your slope.
Paver driveways run $7,000 – $18,000, paver patios $3,500 – $11,000, and driveway replacement $5,000 – $14,000, depending on size, base condition, and drainage work. Estimates are free – call (877) 688-9930 for an exact quote on your lot.
