CWS Driveway & Pavers Nationwide

CWS Driveway & Pavers: The Pomona Owner’s Guide

We stock and install CWS-compatible driveway and paver components in Pomona, with replacement work typically running $5,000-$14,000 for full driveway replacement and $250-$700 for sealing and minor paver restoration. Most CWS paver and driveway issues we see in Pomona are diagnosed same-day, with parts sourced from our network of fifty-plus vetted brands including Belgard and Techo-Bloc. The first sign of trouble is usually settlement cracking near the garage apron or paver shifting after winter rain, when the decomposed granite base beneath CWS installations washes out faster than the manufacturer spec anticipates in clay-heavy Pomona soil.

Which CWS Models This Applies To

CWS driveway and paver systems span three product generations, and the part you need depends on when your surface was installed. Pre-2018 CWS installations used a 60mm paver on a 4-inch aggregate base with polymeric sand jointing, while 2018-2023 systems moved to 80mm pavers with a modified binder layer. The current CWS specification calls for 80mm pavers over 6 inches of class 2 base with geotextile separation fabric.

To identify your system, check the edge restraint. Pre-2018 CWS used plastic paver edging with 10-inch galvanized spikes; 2018 and later switched to aluminum edging with 12-inch spikes. The model designation is sometimes stamped on the underside of a lifted corner paver, though in Pomona’s inland heat that marking fades within three years. If you can’t find it, measure paver thickness and base depth at an expansion joint, that’s enough for us to match the correct replacement profile and bedding sand specification.

We are an independent service provider, not affiliated with CWS. For OEM-equivalent performance, we source from Belgard and Techo-Bloc, whose dimensional tolerances match CWS specs within 1mm, critical for interlock integrity on replacement sections. Aftermarket pavers save 15-20% on material cost without the CWS brand markup, and we warranty the installation the same either way.

Signs Your CWS Driveway & Pavers Is Failing

• Paver lifting or “popping” at the garage transition. This happens when the concrete apron settles independently from the paver bed, usually because the CWS base wasn’t tied into the garage footer with rebar dowels. In Pomona’s expansive clay soils, that gap opens every dry season and closes in winter, cycling the pavers until they crown.
• Water pooling in the center of the driveway after light rain. The CWS cross-slope specification calls for 2% drainage, but if the screed layer compacted unevenly or the base washed, you’ll get birdbaths. Standing water accelerates paver efflorescence and weakens the bedding sand’s polymer bond.
• Joint sand washing out between pavers, leaving gaps. Polymeric sand degrades faster in Pomona’s UV exposure and occasional hard rain. Once the joint seal fails, the base layer begins eroding from underneath, and the pavers lose the friction that keeps them locked.
• Cracking in concrete driveway sections, especially radiating from the control joints. CWS concrete driveways use fiber mesh reinforcement, but if the subgrade wasn’t properly compacted to 95% standard Proctor density, differential settlement cracks the slab. These cracks rarely stay hairline; they widen as vegetation takes hold.
• Color fading or surface spalling on decorative CWS finishes. Pomona’s inland sun exposure, 20% higher than coastal baselines, degrades integral color hardeners within 7-10 years. Spalling, where the surface flakes, indicates freeze-thaw damage or salt intrusion from de-icing products used in nearby mountain communities.

Replacement Cost & What’s Included

The range depends on three things: how much of the base layer has failed, whether we need to bring in engineered fill for Pomona’s clay soils, and paver material grade. Under Clause 1 of the Haven Standard, the price we write is the price you pay; no change order moves forward without your signature. Every driveway job carries our 365-Day Done Right Promise and a documented photo record of base conditions before we cover them.

DIY or Call Us?

There’s a honest split here, and we’ll show you where it falls.

What you can safely check yourself: Lift one paver at the failure edge and measure base depth with a screwdriver. If you hit solid aggregate within 4 inches, the base is probably intact and you’re looking at a bedding layer issue. Check the slope with a 4-foot level, water should run off, not pool. These checks tell you whether you’re facing a $700 seal-and-refresh or a $7,000 base rebuild.

Where DIY goes wrong: Excavating and recompacting base material requires a plate compactor rated for 5,000 pounds of centrifugal force, minimum, and most rental units in Pomona don’t hit that spec for clay soils. More critically, if your CWS driveway ties into municipal sidewalk or curb, any cut beyond the property line requires a City of Pomona encroachment permit, and unpermitted work there triggers a stop-work order we’ve had to clean up more than once. “Measure twice, then we can talk” applies to permits too.

Call (626) 606-1081 and we’ll diagnose it on-site, no charge for the estimate, with a written price before any work starts.
