Unilock Construction in Colma, CA | Workshop Contractors
We’re an independent hardscape and general contracting crew installing, repairing, and rebuilding Unilock paver systems across Colma, CA. What separates our Unilock work here from anywhere else on the Peninsula is ground preparation: Colma’s cemetery-substrate soil moves water differently than typical Bay Area clay, and that changes how a paver base gets compacted, how walls get anchored, and how joint sand gets specified. We’ve been working this ground for years, and we build Unilock systems to hold up under fog, wind, and the town’s unique excavation rules. Call (844) 384-3361 for a free estimate on any Unilock project in Colma.
Why Colma Residents Choose Us for Unilock Service
Colma isn’t a typical residential hardscape market. The buildable land between the cemeteries runs along El Camino Real and the Mission Street edge, dominated by commercial showrooms, civic buildings, and monument-adjacent plazas. That means the Unilock work here lands on memorial walkways, dealership frontages, and columbarium plinths, not backyard patios in a subdivision. Our crew has worked those sites, and we know what the town’s sandy, drained soil does to a paver base when fog settles in for months at a time.
Noel Figueroa, Owner & General Contractor at Workshop Contractors, grew up around tradesmen who framed houses by hand, and he brought that same “build it right the first time” standard to every hardscape job we run. His grandfather built the family home in Pomona with his own hands, and that’s the lens Noel brings to a Unilock installation in Colma: if the base isn’t right, the prettiest pavers in the catalog won’t save you. We’re a single-source contractor and our General Contractor in Colma team means the crew that excavates your Colma site is the same crew that lays the Unilock units and the same crew that stands behind the finished work.

Common Unilock Construction Problems We Solve in Colma
- Brussels Block efflorescence and joint-sand washout. Colma’s sandy, drained cemetery substrate moves water fast. After a wet winter, we see Brussels Block fields where the edge restraint heaved and the joint sand washed out completely, leaving units loose and uneven. We re-compact the base, reset the units, and spec polymeric joint sand that actually holds in the coastal damp.
- Beacon Hill flagstone cap cracking on memorial plinths. Near El Camino Real, irrigation runoff pools against columbarium and memorial structures. When saturated mortar beds hit a cold snap, the Beacon Hill caps crack. We remove the failed caps, address the drainage that caused the saturation, and reset them on properly sloped beds.
- Estate Wall settling and rotation on cemetery-adjacent lots. The sandy fill around Colma’s cemetery edges never got the compaction a structural wall needs. Estate Wall units start to settle, rotate, and the wall loses its batter. We dismantle, re-compact in lifts, and rebuild with Unilock OEM units and proper geogrid where the wall height calls for it.
- Lineo Wall staining and pitting on commercial facades. Showrooms and funeral homes along the Mission Street edge sit in the salt-fog zone. Lineo Wall’s smooth-face units stain and pit when installers used standard steel anchors. We replace with corrosion-resistant stainless anchors and clean the units with methods that won’t etch the face.
- Driveway and patio base failure from rapid drainage. Colma’s sandy substrate drains so fast that an under-compacted base settles unevenly within a year. We see paver driveways and patios with dips and ridges where the base was never keyed into the native soil properly. We fix it by excavating to stable ground and rebuilding the base in compacted lifts.
Unilock Service in Colma: What Local Conditions Mean for Your Equipment
Here’s the thing about working in Colma that no generic Unilock page will tell you: because the town’s ground is essentially cemetery substrate, any excavation for a paver patio, driveway, or retaining wall can trigger a mandatory archaeological and cultural monitor requirement. That’s not a suggestion. It’s a condition of disturbing soil in Colma, and it can stop a job cold if the schedule doesn’t account for it. Our base-prep and grading plan gets sequenced around monitor availability, not just crew schedule. We coordinate the excavation windows with the monitor’s visits so the job keeps moving. That requirement simply does not exist on a typical Peninsula hardscape job in Daly City or Unilock service in South San Francisco. It’s unique to Colma, and it’s the first thing we plan for when a client calls about Unilock work here.
On a memorial-plaza paver walk near El Camino Real, our crew pulled up a failing Brussels Block field where joint sand had washed out and the edge restraint heaved after a wet winter. We re-compacted the sandy base, reset the units on a fresh aggregate bed with polymeric joint sand and stainless edging, and coordinated the work around the cultural monitor’s scheduled visits so the job never stopped cold. The walk now drains away from the columbarium plinths instead of pooling against them.
Unilock Models & Products We Service in Colma
We install and repair the Unilock lines that show up most often on Colma’s commercial and monument-adjacent sites: Brussels Block for paver fields and walkways, Beacon Hill flagstone for caps and plinth work, Estate Wall for retaining walls on cemetery-adjacent lots, and Lineo Wall for smooth-face walls against showroom and funeral-home facades. We stock Unilock OEM segmental units, caps, and geogrid for structural walls and visible hardscape. For base aggregate, polymeric joint sand, and fasteners, we spec quality aftermarket materials that outperform OEM in Colma’s salt-fog and sandy-soil conditions. That’s the right mix: OEM where the unit is visible or structural, aftermarket where coastal conditions demand better than factory spec.

FAQs – Unilock Construction in Colma
No, not reliably. Any ground disturbance in Colma can trigger a mandatory archaeological/cultural monitor, and skipping that step puts the project at legal risk. We sequence the excavation around monitor availability so the job keeps moving. Call (844) 384-3361 and we’ll tell you whether your specific site is likely to need one.
Yes, if the base and joint sand are done right. Brussels Block is a solid paver, but Colma’s damp, foggy conditions will wash out joint sand fast if the edge restraint isn’t sturdy and the base isn’t keyed into the sandy soil. We use polymeric joint sand and stainless edging specifically for the coastal damp. Call (844) 384-3361 to get a base assessment.
We repair them whenever the units are still sound. A settled Estate Wall or Lineo Wall in Colma usually means the sandy fill was never compacted properly. We dismantle, re-compact in lifts, and rebuild with OEM units and proper geogrid. Replacement is only the call when base failure or wall movement makes re-laying unsafe. Call (844) 384-3361 for an assessment.
For a typical Colma paver patio, budget $3,500 to $11,000 depending on square footage, base condition, and whether the cultural monitor requirement applies to the excavation. The base is where the money goes, not the pavers themselves. Call (844) 384-3361 for a line-item estimate on your specific site.
Yes. Unilock’s color blends are consistent across production runs, so we can source matching units for a repair or extension. The bigger factor in Colma is weathering: the existing field has been in the fog and salt air, and new units have not. We can sometimes blend the transition with proper cleaning and joint sand. Call (844) 384-3361 to discuss your specific match.
