Unilock Construction in Mission District, CA | Iron Beam Contractors
Iron Beam Contractors installs and repairs Unilock paver patios, driveways, and segmental retaining walls throughout our Home Remodeling in Mission District. We’re an independent contractor, not a manufacturer dealer, and the thing that separates our work here is straightforward: most Mission District paver failures start underground, in the filled creek beds and dune sand this neighborhood was built on. If your Unilock surface is settling, heaving, or draining toward your foundation, call (833) 756-5936 for a free estimate.
Why Mission District Residents Choose Us for Unilock Service
We’ve worked Unilock paver fields on lots between Mission and Valencia where the ground underneath hasn’t been touched since the 1880s. That matters because Unilock’s Brussels Block and Beacon Hill units are only as stable as the base they sit on. Nolan Driscoll, who owns Iron Beam Contractors, came up through the Building and Construction Technology program at Santiago Canyon College and spent two decades framing and pouring before he ever touched a paver. He’ll tell you the same thing on every Mission District General Contractor job: if the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam. Or a paver.
We carry OEM-compatible edge restraint and the correct Unilock color blends for the profiles you already have, so a repair doesn’t look like a patch job. And because we’re local to the district, we also know where to find Chinatown Unilock service when needed, and we quote jobs against the actual site conditions here, not a stock photo from a catalog.

Common Unilock Construction Problems We Solve in Mission District
- Edge restraint and joint sand failure over undocumented fill. When a paver field goes down over old Mission Creek mud that was never properly over-excavated and compacted, the edges creep and the joints empty out within two winters. We lift the field, re-cut the base, and re-set with the right Unilock restraint and polymeric sand.
- Rutting at driveway aprons on raised-foundation rowhouses. Mission District’s 1880s-1920s flats sit on soft soil that moves against the structure after a wet winter. Driveway aprons take the worst of it, and we see rutting and differential settlement that no amount of paver-leveling will fix without addressing the base first.
- Drainage ponding against soft-story ground floors. A paver patio pitched off a sample board instead of a real lot survey will send water toward the building. On Mission District’s flat lots, that means ponding against historic facades and soft-story ground floors. We shoot grades and re-pitch the field to shed to the street, like it should have been from day one.
- Sand migration and efflorescence on fog-cooled north-facing patios. The Mission gets sun, sure, but the fog-cooled blocks south of 20th hold moisture longer. Joint sand washes out and white mineral deposits bloom on the paver face. We re-sand and seal correctly for the microclimate, not for a generic Bay Area spec.
- Trip-hazard lips at paver-to-slab thresholds. Original doorways on Italianate and Edwardian flats often sit proud of a settled paver field. We re-level the field to meet the original threshold cleanly, because a quarter-inch lip is a liability and a bad look.
Unilock Service in Mission District: What Local Conditions Mean for Your Equipment
Mission District’s historic street grid was laid directly over filled Mission Creek and former sand dunes. That’s not trivia; it’s the reason excavating for a paver base here regularly turns up old creek-bed mud, undocumented fill, and buried foundations. We’ve dug for a modest rear patio off Valencia near 24th and hit a buried brick foundation from a long-gone outbuilding on the first pass. Because much of the district sits inside a designated conservation area, a rear paver patio or driveway apron can also pull in historic-review conditions that a same-size job in, say, Noe Valley never triggers. For Unilock owners, that means the base prep is the project. The paver face is the easy part. Any contractor who quotes a Mission District paver job without planning for over-excavation and possible permit review is guessing, and you’ll pay for that guess in three years when the field starts moving.
Unilock Models & Products We Service in Mission District
We work with the Unilock lines that show up most often in Mission District yards and driveways: Brussels Block, Brussels Dimensional, Beacon Hill, and the U-Cara retaining wall system. When a repair calls for matching, we order the actual Unilock profile and color blend, not a close-enough substitute from a different yard. We keep common edge restraints and joint sand staged for fast turnaround in the 94110, and we re-do base prep ourselves rather than handing it to a sub who spends the week pouring flatwork. The base is what fails here, not the paver face. See our Unilock sales & service page for the full scope of what we carry and install.

What drives cost in Mission District more than anywhere else is base work. If the soil under your lot is creek fill, we’re over-excavating and bringing in compaction-tested aggregate before a single paver drops. That’s not a change order; it’s the job done right. A free estimate includes a walk of the site, a look at the existing grade, and a written line-item quote. Call (833) 756-5936 to get one scheduled.

FAQs – Unilock Construction in Mission District
Because the Mission’s street grid sits on filled creek bed and dune sand, so a standard 6-inch compacted base often isn’t enough. We excavate until we hit competent soil, then build back up with tested aggregate. That’s the only way a Unilock field stays flat here. Call (833) 756-5936 and we’ll tell you what your lot actually needs.
It can. Much of the Mission District is a designated conservation area, and even a rear-yard scope can pull a historic-review condition, especially if the property is a contributing structure. We document the existing layout and materials before ordering anything, which has cleared review on multiple jobs. If you’re not sure whether your address falls inside the boundary, ask us and we’ll check before you spend a dime.
We shoot the actual fall of the lot and pitch the paver field to drain away from the structure and toward the street. On Mission District’s flat lots, that often means re-grading more of the yard than you’d think. Water against a soft-story ground floor or a 1905 facade is a structural problem wearing a landscaping costume.
Usually, yes. If the base is still sound, we lift the affected area, re-level, re-compact, and re-sand with the matching Unilock profile and joint material. When the base is shot, you can still lift and re-set, but you’ll need base work first. We’ll tell you which one you’re looking at before we quote anything.
On a narrow Mission District parcel, the apron is often original concrete or brick set against the sidewalk, and the driveway field sits directly against the neighbor’s wall line. We saw-cut clean edges, haul off the old material, re-grade for positive drainage, and set the new Unilock field with proper edge restraint. Tight access means hand work and smaller equipment, which is why those jobs land in the $5,000 to $14,000 range. Call (833) 756-5936 for an exact number.
