CWS Driveway & Pavers Nationwide

CWS Driveway & Pavers: The Campbell Owner’s Guide

We stock and install CWS-compatible driveway and paver components in Campbell, with most replacements running $5,000-$14,000 for a full driveway replacement and $250-$700 for sealing work, depending on substrate condition and square footage. Most CWS paver and concrete driveway parts and full assemblies are available same-day through our supplier network, and we carry common edge restraints, drainage channel components, and polymeric sand on our trucks. Campbell homeowners usually discover a problem when they notice pooling water after our winter rains, shifting pavers along the driveway edge near the garage, or hairline cracks spreading from the street apron where the CWS base preparation met the city’s curb cut.

Which CWS Models This Applies To

CWS produced several driveway and hardscape product lines between the late 1990s and mid-2010s, and the part you need depends on which series was originally installed. The CWS Classic Cobble and CWS Pro-Loc permeable paver systems are the two most common in Campbell, particularly in the neighborhoods east of Winchester Boulevard where they were specified by several tract builders in the early 2000s. To identify your series, look for the raised lug pattern on the paver edge: Classic Cobble has a single offset lug, while Pro-Loc uses a double-lug interlock designed for heavier vehicle loads.

We source OEM CWS replacement pavers when the color batch is still available, though several Campbell-area suppliers have depleted their stock of the tan-and-brown blend used in the Pruneyard-adjacent developments. When OEM color-matching is not possible, we use Belgard or Techo-Bloc equivalents with comparable compressive strength (8,000 psi minimum) and document the substitution in your written scope. For edge restraints and drainage components, we typically install Versa-Lok or NDS aftermarket equivalents that exceed the original CWS specifications. Bring a photo of the paver underside and any remaining packaging; if you have the original installation invoice, the CWS lot number is usually stamped in the upper right corner.

Signs Your CWS Driveway & Pavers Is Failing

• Pavers rocking or settling unevenly under tire weight. This usually means the CWS bedding sand layer has washed out or the base compacted improperly during our dry Campbell summers, leaving voids that let individual stones shift with each vehicle pass.
• Standing water more than 30 minutes after rain stops. The CWS permeable paver system relies on a specific aggregate base depth, typically 6-8 inches for residential driveways, and when that base clogs with fine silt from nearby landscaping, water has nowhere to drain.
• Cracks radiating from the garage threshold or street apron. These are the highest-stress zones on any driveway; CWS installations without adequate expansion joints or fiber-mesh reinforcement in the concrete sub-base will telegraph those stresses upward within 8-12 years in our climate.
• Weeds growing through paver joints despite previous sealing. The CWS-recommended polymeric sand degrades faster in Campbell’s combination of UV exposure and occasional heavy winter rain, breaking its bond and creating germination pockets.
• White efflorescence blooming on paver surfaces. This mineral deposit indicates moisture is migrating through the CWS paver body from below, often because the vapor barrier beneath the base was omitted or damaged during original construction.

Replacement Cost & What’s Included

For Campbell properties, CWS driveway and paver work falls into clear price brackets based on what actually needs doing. A full CWS paver driveway replacement runs $7,000-$18,000, while a concrete driveway replacement is typically $5,000-$14,000. Spot repairs, such as re-leveling a settled section or replacing damaged edge restraint, range from $800-$2,500 depending on square footage and whether we need to match discontinued CWS color blends.

Every quote we write in Campbell includes demolition and disposal of the failed surface, base inspection and re-compaction where needed, installation of new material per manufacturer spec, and polymeric sand or sealant application. We pull permits when the project exceeds 200 square feet or involves curb cuts, and we pass inspection before final payment. Under Clause 1 of the Haven Standard, the price you sign is the price you pay; no change order moves forward without your signature, which is how we’ve kept 4,000-plus projects within a few percent of the original number since 2007. Our 365-Day Done Right Promise covers the installation workmanship, and we leave you with a documented photo record of the base condition, compaction test results, and finished surface.

DIY or Call Us?

There is no high-tension danger in driveway work the way there is with garage door springs or electrical panels, but there is a costly mistake we see regularly in Campbell: homeowners pull up a few settled pavers, add fresh sand, and tamp them down without checking the base depth or drainage slope. Six months later the same pavers settle again, and the repair area no longer matches the weathered surface around it.

What you can safely check yourself: verify whether the settling is isolated to a small area (under 10 square feet), look for obvious drainage blockages like compacted leaves in the channel, and photograph any cracks before they widen. What goes wrong with DIY: improper base compaction (a plate compactor rental runs $80/day but requires experience to judge adequate density), incorrect bedding sand gradation (concrete sand, not masonry sand, is the CWS spec), and mismatched paver colors that make the repair obvious from the street. We carry compaction testing equipment, stock Belgard and Techo-Bloc equivalents for discontinued CWS colors, and can usually assess whether a spot repair or full replacement makes financial sense.
