Unilock Construction in Colma, CA
We install and repair Unilock paver patios, driveways, and walkways across Colma’s 94015, and also offer Unilock service in South San Francisco. Garden Grove Contractors is an independent hardscape crew, not a Unilock dealer or authorized rep. What makes our Unilock work in Colma different is drainage: this town sits in a fog belt where the ground stays damp ten months a year, and a paver base built to inland standards fails here within a season or two. Call (877) 373-9230 for a free estimate on paver installation or a re-set of failing Unilock work.
Why Colma Residents Choose Us for Unilock Service
Noel Cardenas grew up in Garden Grove and came up through the trades at Santiago Canyon College before spending years on residential and commercial builds across Southern California. He brought that same hands-on approach to the Bay Area, and our crew has laid and repaired Unilock pavers in Colma long enough to know exactly how Brussels Block and Beacon Hill behave under persistent coastal fog. We use genuine Unilock units, matching edge restraint, and the correct polymeric joint sand for each series. We are not authorized by Unilock, and we won’t pretend otherwise. What we are is a general contractor with full-scope capability, from Unilock sales & service to roofing, windows, and interior remodels, so your hardscape isn’t a handoff to a specialist who disappears after the pavers go down.

Common Unilock Construction Problems We Solve in Colma
- Efflorescence bloom on Brussels Block and Beacon Hill faces. Colma’s fog keeps paver surfaces damp well past noon. Moisture wicks up through the units and leaves white mineral deposits on the face. The fix is not just scrubbing: it’s correcting the drainage and capillary break beneath the units so water stops moving upward through them.
- Joint sand washout and rocking units. Cool, moist soils in Colma never fully dry, and capillary wicking pulls the fine joint sand out from between pavers. Once the sand is gone, the units shift and rock under foot. We re-sand with polymeric material rated for damp-climate work, but only after confirming the base drains.
- Edge restraint corrosion from salt-laden air. Colma sits just south of San Francisco, close enough to the coast that the air carries salt. Steel and standard aluminum edging corrode faster here than inland, and when the edge fails, the whole field loses its lock. We spec corrosion-resistant restraint on every Colma job.
- Settlement and lipping at apron and threshold transitions. Cemetery and retail site work in Colma leaves behind mixed fill, and pavers set over thin base or old concrete without over-excavation sink within a year. The result is tripping hazards at driveways and door thresholds. We over-excavate and recompact before anything gets laid.
- Base failure from trapped moisture. The standard inland paver spec, a thin sand-set over compacted fill, ponds and wicks in Colma’s high water table. When the base traps moisture, no sealer or re-sanding fixes it. The base gets pulled and rebuilt with free-draining aggregate and geotextile separation.
Unilock Service in Colma: What Local Conditions Mean for Your Project
Colma’s commercial and cemetery sites share a single fog-belt water table that stays high and cold year-round. That means a Unilock paver base here needs a free-draining, geotextile-separated aggregate section with positive fall to a defined outlet. The exact same paver spec laid inland will pond, wick, and bloom its joints within one Colma season. We learned this the direct way on a retail pad near El Camino Real in 94015, where our crew re-set a worn Unilock Beacon Hill walkway. The original thin sand-set base had trapped fog moisture and the joint sand was completely gone, leaving the units rocking underfoot. We pulled the field, over-excavated to a drained aggregate section with separation fabric, set fresh edge restraint that can handle the salting air, re-laid the Beacon Hill with polymeric sand, and left the surface falling to a new outlet so it sheds water instead of soaking in it. That’s the difference between a Colma paver job that lasts and one that fails before the next fog season ends.
Unilock Models & Products We Service in Colma
We install and repair the Unilock lines most common in Colma’s commercial and residential work: Brussels Block, Beacon Hill, Town Hall, and Estate Wall. Our approach to parts is straightforward: we use genuine Unilock units and matching accessory pieces, edge restraint, polymeric joint sand, and cap profiles made for the specific series. Mismatched aftermarket sand and generic edging are where most fog-belt paver failures start. If the base is sound and only the surface is tired, a lift-and-relay with new sand saves the field and cuts the cost well below a full rebuild. If the base has failed from trapped moisture, no sealer or re-sanding fixes it, and the base gets rebuilt properly.

FAQs – Unilock Construction in Colma
A paver driveway in Colma runs $7,000 to $18,000, and a paver patio runs $3,500 to $11,000. The range depends on square footage, base depth, drainage corrections, and whether we’re replacing an existing surface or starting fresh. Colma’s high water table tends to push base prep toward the upper end because skipping it means the pavers fail within a season. Call (877) 373-9230 for an exact quote, or learn more about our Home Remodeling in Colma; estimates are free.

We use genuine Unilock units, edge restraint, cap profiles, and polymeric joint sand made for the specific series we’re installing. Generic aftermarket sand and edging are the root cause of most fog-belt paver failures we see in Colma, so we don’t cut that corner.
