Unilock Construction in Interlaken, CA | Timberline Contractors
We install and repair Unilock paver patios, driveways, and retaining walls across Interlaken as an Interlaken General Contractor and independent hardscape crew. The one thing that makes our Unilock work here different is drainage design, because Interlaken’s flat Pajaro Valley floor pools stormwater instead of shedding it, and a paver base that isn’t pitched and edged correctly will fail within two or three wet winters. If you’re planning a Unilock patio or fixing a heaved one in ZIP 95019, call (866) 253-5808 for a free estimate.
Why Interlaken Residents Choose Us for Unilock Service
Nelson Fung, our owner and general contractor, learned the trade formally at Los Angeles Trade-Technical College before spending years on remodels and commercial builds across the LA basin. He’ll tell you exactly where a cheaper base prep makes sense and exactly where it will cost you twice as much in three years, and he still geeks out over the difference between a properly compacted aggregate base and one that just looks flat. For Unilock sales & service, that obsession matters.
We work with the full Unilock line, from Brussels Block to Beacon Hill Flagstone, and we stock genuine Unilock units and matching ArmorTec accessories for color-consistent repairs. Interlaken homeowners call us for Unilock service in Freedom and nearby because we know the difference between a paver job that holds up through wet winters and one that starts shifting by March. Do it right the first time or explain yourself twice.

Common Unilock Construction Problems We Solve in Interlaken
- ArmorTec face chalking on Cambridge pavers. Salt-laden marine fog off Monterey Bay settles on paver surfaces, and when sealer is skipped or applied unevenly, the ArmorTec face can chalk and dull faster than inland. We clean, re-seal, and restore the finish so the color stays consistent across the whole field.
- Polymeric sand washout on flat grades. Interlaken’s table-flat terrain means water doesn’t run off a patio, it sits on it. Heavy winter storms push water across Brussels Block joints and wash out polymeric sand, leaving gaps that invite weeds and shifting. We re-sand with a high-performance joint stabilizer and correct the base pitch so it stops happening.
- Bulging or leaning Brussels Dimensional Stone walls. Retaining walls built without geogrid and free-draining gravel backfill lean after one or two saturated winters. We see this on older Interlaken lots where the original hardscape was done by someone who skipped the drainage layer. We rebuild the wall properly or repair the section, depending on how far the movement runs.
- Efflorescence on Beacon Hill Flagstone. White mineral blooms form when base prep traps moisture under the pavers, and Interlaken’s older lots with poor surface drainage make it worse. We identify where the moisture is coming from, fix the drainage, and clean the bloom so it doesn’t return.
- Heaved paver driveways after winter storms. When the flat Pajaro Valley floor pools water under a paver driveway, the base goes soft and units start heaving. We re-excavate, compact a proper aggregate base with positive slope, and reset the pavers so the driveway sheds water instead of absorbing it.
Unilock Service in Interlaken: What Local Conditions Mean for Your Hardscape
Here’s what most paver installers miss about Interlaken: the Pajaro Valley is so flat that stormwater doesn’t run off naturally, which means every Unilock patio, walkway, and driveway here needs a pitched base and perimeter drainage designed before the first unit is laid. On a recent job off the flat farm-belt streets of ZIP 95019, our crew pulled up a heaved Brussels Block patio where winter water had nowhere to go and the base had gone soft. We re-excavated to a compacted aggregate base with a positive slope and a gravel-and-drain edge, reset the ArmorTec pavers, and finished with fresh polymeric sand. That patio has shed two rainy seasons since without shifting. Inland paver jobs can skip this step and get away with it. In Interlaken, the drainage layer isn’t optional, it’s the job.
Unilock Models & Products We Service in Interlaken
We install and repair the full Unilock line, including Brussels Block, Cambridge Pavingstones with ArmorTec, Beacon Hill Flagstone, and Brussels Dimensional Stone wall units. For repairs, we source genuine Unilock units and matching ArmorTec accessories so color and dimension stay consistent with the existing field. We don’t substitute off-brand units that fade or dimension differently over time. Where a patio or walkway has isolated damage, we reset and re-sand those units. Full replacement is only warranted when base failure or wall movement runs under the whole field. If you’re in Interlaken service area, we can take a look and tell you which path makes sense before you spend a dollar.

AfterUnilock Service Pricing in Interlaken
Unilock hardscape pricing in Interlaken depends on the size of the field, the condition of the base, and whether drainage needs to be corrected. Here are the market-calibrated ranges we work within:
| Service | Price Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
What drives the cost most in Interlaken is how much base re-excavation and drainage correction the site needs. A paver patio on a lot that already drains costs less than one where we have to add a pitched base and perimeter drain because the flat valley floor pools water. Every free estimate includes a written line-item quote with fixed pricing and no change orders. Call (866) 253-5808 for an exact number.

FAQs – Unilock Construction in Interlaken
Yes, Unilock pavers hold up well in Interlaken, but only when the base is pitched for drainage and the surface is sealed against marine fog. The two failure points we see are water pooling on flat grades and salt-laden fog dulling ArmorTec faces when sealer is skipped. A properly pitched base with perimeter drainage and a quality sealer solves both. Call (866) 253-5808 for a free drainage assessment.
Yes, efflorescence shows up on Unilock pavers in Interlaken when moisture gets trapped under the units, especially on older lots with poor surface drainage. The white bloom is mineral deposits left behind as water evaporates. Fixing it means finding where the moisture is coming from, improving drainage, and cleaning the surface. A quick cleaning without fixing the drainage just means it comes back. We include drainage correction in our repair scopes, and estimates are free at (866) 253-5808.
A Unilock paver patio in Interlaken typically runs $3,500 to $11,000, and a paver driveway runs $7,000 to $18,000. Your exact number depends on the field size, base condition, and whether we need to add drainage correction for the flat Pajaro Valley grade. Every quote is line-item and fixed. Call (866) 253-5808 to schedule a free estimate and get a real number.
Yes, if the wall movement is isolated to a section, we can repair it. If the geogrid and gravel backfill were never installed or the whole wall is leaning, rebuilding is the honest answer. We’ll tell you which one applies to your wall after we look at it. Call (866) 253-5808 for a free inspection and written recommendation.
