Unilock Construction in Felton, CA | Iron Beam Contractors
We install and repair Unilock hardscapes across Felton as a Felton General Contractor, not a manufacturer-authorized dealer. The work here isn’t flat-lot paving. Every paver base, retaining wall, and driveway apron we build in Felton is engineered around slopes, redwood roots, and winter storm runoff that drains toward the San Lorenzo River. Call (833) 756-5936 for a free estimate on any Unilock project in the 95018.
We source genuine Unilock units through the brand’s regional distributors, which means you get real Brussels Block, Beacon Hill Flagstone, and Pisa2 wall components, not lookalike substitutes. Pair that with our drainage and hillside experience, and you have a hardscape that actually holds in Felton’s conditions.
Why Felton Residents Choose Us for Unilock Service
Nolan Driscoll, our owner, cut his teeth on structural work where the ground doesn’t cooperate. He grew up in Orange County’s Friendly Hills, spent enough time at Santiago Oaks to read clay and grade before most engineers open a laptop, and came up through the Building and Construction Technology program at Santiago Canyon College. Then he spent two-plus decades framing, pouring, and reinforcing everything from single-family additions to commercial tenant improvements. The lesson that stuck: tell the homeowner what’s in the wall before you open it, not after.
That matters in Felton because Unilock work here is never just pavers on sand. It’s base excavation through redwood duff, drainage that carries winter sheet flow away from foundations, and walls stepped into hillside grade with proper batter and geogrid. We handle Unilock sales & service as one accountable team, which means the paver work, the retaining wall, the French drain behind it, and the stormwater exit all fall under the same contract. No finger-pointing between a paver crew and a drainage guy.
We’re fully licensed and insured, and every quote is a written line item with fixed pricing. You’ll see the paver cost, the excavation cost, the drainage cost, and the geogrid cost separately. No change orders hiding behind vague “site conditions” language.

Common Unilock Construction Problems We Solve in Felton
- Efflorescence bloom on Brussels Block and Beacon Hill pavers. Wet winters saturate the base course. When it dries slowly on redwood-shaded lots, salt migrates to the paver surface and leaves that chalky white haze. It’s cosmetic, not structural, but it looks wrong. We clean and reseal with the right products, and we address the drainage that kept the base wet in the first place.
- Pisa2 retaining wall courses bowing or settling. This is the most common hillside failure we see in Felton. A wall built on a flat-lot spec, no batter, no geogrid tie-back, no stepped base. Two wet winters later the top courses lean toward the house. That’s a rebuild, not a patch job.
- Polymeric sand washing out of paver joints. On sloped driveways and patio edges, winter sheet flow concentrates and scours joints clean. Without an underdrain, the sand goes first, then the pavers start shifting. We regrade, install drainage, and re-sand with a quality polymeric product.
- Heaved and shifted pavers along driveway aprons. Redwood roots and freeze-thaw cycles in shaded soil push pavers out of plane. The real cause is usually base excavation that stopped at organic duff and never got below the root zone. We pull, excavate properly, and recompact.
- Patio-edge failure where hardscape meets slope. The outboard edge of a paver patio on a Felton hillside carries the most load and the most water. Without an edge restraint and a drain, the corner drops and cracks. We rebuild edges with proper restraint and positive drainage.
Unilock Service in Felton: What Local Conditions Mean for Your Equipment
Here’s the thing most paver contractors from San Jose, Unilock in Scotts Valley, or Watsonville don’t internalize about Felton until the first storm season. Felton lots sit on redwood-shaded hillsides above the San Lorenzo River corridor. Ground that looks firm in August is saturated, slow-draining duff and clay by February. A Unilock retaining wall or paver patio here is fundamentally a drainage and slope-stability project wearing a hardscape finish.
Base excavation has to go below the organic layer and root zone, not just scrape the surface flat. The subgrade needs a French drain or underdrain tied to a legal stormwater exit, or the whole assembly becomes a sponge holding water against your foundation. If the hardscape sits near the structure, CAL FIRE defensible-space clearance and Chapter 7A ignition-resistant detailing apply to material choices and layout. These are Felton-specific constraints. Flatland specs don’t address them. 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 in this case, before we lay a paver.
On a sloped parcel off Graham Hill Road, we rebuilt a failing Pisa2 retaining wall that had been set on grade with no batter or geogrid, so the top courses had bowed toward the cabin after two wet winters. We excavated to stable soil, stepped the base down the slope, tied in geogrid and a French drain behind the wall, and relaid Brussels Block on a compacted, underdrained patio above it. The runoff that used to sheet into the cabin foundation now exits below the wall, and the hardscape held through the following storm season.
Unilock Models & Products We Service in Felton
We work with the full Unilock residential line available through regional distributors: Brussels Block and Beacon Hill Flagstone pavers for patios, walkways, and driveway aprons; Pisa2 for segmental retaining walls; and Copthorne and Town Hall pavers for driveways and larger surfaces. Our parts approach is straightforward: we order genuine Unilock units and matching Unilock-branded wall components so color blends and dimensional runs line up with existing hardscape. We spec quality polymeric sand and geogrid, not house-brand substitutes that fail faster in Felton’s wet-dry cycle.
Isolated cracked or heaved pavers are usually worth repairing. A wall that’s bowing or a base that’s washing out is a rebuild of the base and drainage, not a spot fix. We’ll tell you which one you have before we quote.

AfterUnilock Service Pricing in Felton
Costs vary with slope, access, and drainage scope. Felton parcels often mean more excavation, more geogrid, and more drainage than a flat subdivision job, so a straight price-per-square-foot figure from a flatland contractor will miss what your lot actually needs. Here’s where our Unilock work typically lands:
| Service | Typical Felton Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Home Addition (foundation/site work adjacent to hardscape) | $45,000 – $130,000 |

FAQs – Unilock Construction in Felton
Efflorescence is salt migrating to the paver surface as a saturated base dries out. On redwood-shaded, slow-drying Felton lots, winter moisture lingers in the base course and pulls minerals upward. It’s a cosmetic issue, not a structural one, but the fix starts with drainage that lets the base dry. Call (833) 756-5936 and we’ll assess whether you need a cleaner, better drainage, or both.
Yes, and most of the engineering lives in what you don’t see: stepped base excavation, batter into the slope, geogrid tie-backs, and a French drain behind the wall. Skip any of those and the wall bows within a couple of wet seasons. We’ve rebuilt plenty that failed exactly that way. Call (833) 756-5936 for a slope-specific quote.
Pavers themselves are non-combustible, which helps near the immediate 5-foot zone, but the full assembly, including base, layout, and surrounding vegetation, has to satisfy Santa Cruz County and CAL FIRE requirements. If your driveway or patio sits adjacent to the structure, we spec the hardscape and surrounding clearance together so the whole package passes inspection, not just the paver surface.
Root intrusion and slow-draining redwood-shaded soil are the usual culprits. The base wasn’t excavated below the organic duff or root zone, so roots lift pavers and saturated soil loses bearing. The fix is excavation, root pruning where safe, proper compaction, and an underdrain. An estimate is free, call (833) 756-5936.
Yes. We order genuine Unilock units through authorized distributors so color runs and dimensions align with what’s already installed. We’ll bring samples to your site and do a dry lay before committing, so you can see the match in Felton’s actual light, not a showroom. Call (833) 756-5936 to set it up.
