Unilock Construction in San Antonio Heights, CA | San Mateo Construction
We provide independent our General Contractor in San Antonio Heights Unilock construction service across San Antonio Heights, CA. That means paver driveways, patios, and U-Cara retaining walls on the steep, unincorporated foothill lots here, where base prep and drainage detail are the difference between a field that holds for 20 years and one that heaves after two winters. San Mateo Construction installs and repairs Unilock systems county-permitted and hillside-aware. Call Noel at (855) 901-7266 for a free estimate.
Why San Antonio Heights Residents Choose Us for Unilock Service
Because hillside work is fundamentally different from flatland paving. Most San Antonio Heights homes sit on sloping lots cut into the San Gabriel foothills, and we have been installing Unilock segmental pavers and retaining walls on that exact terrain for years. We know what happens to a Brussels Block driveway when the base is not stepped into grade. We know how U-Cara wall caps shift on a slope without geogrid tie-back. That knowledge matters more than any showroom.
We are an independent Unilock installer, not a Unilock dealer or factory outlet. That means we select the right Unilock line for your site instead of pushing whatever happens to be in stock. Noel Carrington runs our crews, and his approach is simple: “Tell me what you actually need, and we’ll figure out the right way to build it.” We also pull permits through San Bernardino County, because San Antonio Heights is unincorporated and this is not an Upland jobsite. If you want Unilock done right on a hillside, call (855) 901-7266.

Common Unilock Construction Problems We Solve in San Antonio Heights
- Paver rotation and base settlement on sloped driveways. The classic San Antonio Heights problem. The original compacted aggregate base was laid flat instead of stepped into the hillside grade, so the field rotates and dips within a few storm cycles. We pull the pavers, rebuild the base in lifts, and re-set the same units if they are sound.
- Sand joint washout after winter rain and Santa Ana wind. Canyon lots shed water fast, and wind-driven debris scours the joints. When the edge restraint gives way, pavers spread and open up. We repair the edge, re-sand with the right polymeric grit, and stabilize the field before further spreading occurs.
- Efflorescence and surface staining on Brussels Block and Yorkville units. Full Western exposure plus irrigation overspray leaves white mineral bloom and hard-water staining on lighter-toned pavers. We strip the salts, adjust the irrigation pattern, and seal where the homeowner wants a true color lock.
- Leaning or battering U-Cara retaining walls on slopes. These walls fail when built without geogrid tie-back into the hill. Flatland installers skip it because their sites do not demand it. Here, it is not optional. We re-tie the courses with geogrid and reset the caps.
- Discontinued Unilock color matching. If a paver line is no longer produced, a small repair becomes a field-matching headache. We source remaining stock where available, or blend compatible segmental units that do not shout patch job.
Unilock Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights is unincorporated ground. That is not a formality; it changes the whole job. A paver driveway on Euclid Avenue in Upland pulls a city permit and moves. The same driveway on a hillside lot off Mountain View Avenue pulls a San Bernardino County permit, and if the grade exceeds the county threshold, the plan set goes to geotechnical review before we can even order the base rock. We have had to engineer stepped bases and drainage swales on jobs that would have sailed through a flatland city in a day. For Unilock owners, that means your installer has to know what the county reviewer will flag before the drawings go in. We do, because we have done it here repeatedly. That is the local difference, and it is exactly what most contractors who pick up San Antonio Heights work from the valley below miss.
Unilock Models & Products We Service in San Antonio Heights
We install and repair the Unilock lines that hold up on foothill terrain: Brussels Block for traditional tumbled driveways and walkways, Beacon Hill for flagstone-effect patios, Yorkville for large-format antiqued fields, and U-Cara or U-Cara Multi-Face for segmental retaining walls on slopes. When a repair requires new units, we use genuine Unilock block and matching edge restraints and caps wherever the color and profile remain in production. If a line is discontinued, we source compatible segmental replacement units we have verified against the existing field. We do not push a full replacement when the pavers are sound. Lifting and re-setting the existing field on a corrected base is almost always the better call. Unilock sales & service matters only as much as the sub-surface below it. That is where we spend the attention.

FAQs – Unilock Construction in San Antonio Heights
Yes, when the base is stepped into the hillside grade and edge restraint is properly tied, Unilock fields hold on slopes as well as they do on flat ground. The failures we see are almost always base failures, not unit failures. We re-build bases with the slope in mind, not the way the original flatland installer did it. If your driveway is heaving, call (855) 901-7266 and we will assess what is happening underneath.
Yes, and we prefer it. If the Brussels Block or Yorkville units are intact, we lift them, re-grade the base in compacted lifts, re-set the field, and re-sand the joints. Replacement is only the right call when the units are cracked, chipped, or so worn that color matching becomes impossible. Call (855) 901-7266 for an exact take on your field.
In San Antonio Heights, yes, in most cases. Because the area is unincorporated, permitting runs through San Bernardino County, not Unilock in Upland. Sloped drives and large retaining walls often go to geotechnical review as well. We handle the full permit package and inspections. Call (855) 901-7266 and we will map out what your project needs before anything gets built.
Yes, particularly the U-Cara and U-Cara Multi-Face systems, when they are built with geogrid tie-back into the slope. We see U-Cara walls leaning and losing cap course on San Antonio Heights slopes where the original builder skipped geogrid because a flatland code did not require it. Here, the slope does require it. We re-tie failed walls and build new ones so they hold through the next rainy season. Call (855) 901-7266 for an evaluation.
Lighter Brussels Block and Beacon Hill units can show efflorescence and staining, especially where irrigation overspray hits the field in the foothill heat. The salts and hard-water minerals are cleanable with the right acid-blend stripper, and we often pair that with a sealer after cleaning. We also review your irrigation heads so the problem does not come right back. Call (855) 901-7266 for a cleaning and sealing quote.
