Cambridge Pavers Home Additions & ADU: The Fort Worth Owner’s Guide
Adding square footage with Cambridge Pavers hardscape materials typically runs $45,000 – $130,000 in Fort Worth, depending on foundation type, roofline tie-in, and whether you’re building out or up. Most owners call us because an existing paver patio, walkway, or retaining wall is failing underneath a planned addition, or they’re designing an ADU and need the paver work integrated with new footings and drainage. The failed part isn’t always the paver itself. It’s usually what’s beneath it.
Curtis Lane has pulled enough failed Cambridge Paver installs in Fort Worth to know the difference between a product problem and a base problem. The pavers hold. The subgrade gives. That distinction drives every scope we write.
Which Cambridge Pavers Models This Applies To
We work with the full Cambridge Pavingstones with ArmorTec lineup: the RoundTable collection, Ledgestone, Sherwood, Maytrx, and the 60mm commercial-grade systems used on driveways and heavy pedestrian traffic. Here’s the compatibility gotcha most homeowners miss: Cambridge 60mm pavers and 80mm pavers are not interchangeable, even when the face dimensions match. A 60mm Cambridge paver on a residential driveway in Fort Worth’s clay soil will fail where an 80mm paver won’t, because the heavier paver won’t flex when the clay heaves and shifts.
Identifying your paver is straightforward. Flip one over. Cambridge stamps the mold pattern and production date on the underside. The mold number tells us the exact color blend and texture profile. If you can’t find the stamp, measure the thickness with a tape. That number alone tells us whether the original install used the right spec for the application. Cambridge also runs distinct color blends by region, so a Cambridge paver bought in Phoenix won’t always match the same named color sold in Fort Worth. We source through regional distribution to keep blend consistency.
For ADU hardscape, Cambridge offers the same paver lines but the engineering matters differently. The paver field has to tie into the ADU’s foundation drain and swale. We’ve seen more than one garage conversion in Fort Worth where the previous contractor laid Cambridge pavers directly against the slab with no filter fabric separation, and the first big rain washed the joint sand right out.
Styles & brands we work with
Signs Your Cambridge Pavers Home Additions & ADU Is Failing
- Settling at the slab edge. If pavers along the house or new addition’s foundation are sinking below grade, the base wasn’t compacted in lifts. Fort Worth’s black gumbo clay expands and contracts hard, and a poorly compacted base moves with it. The fix requires pulling pavers, re-compacting, and reinstalling.
- Washed-out joints after rain. Joint sand loss means water is moving through the field instead of across it. This is a pitch problem. Cambridge pavers are dense; they shed water well. If water is pooling, the subgrade slope is wrong, not the paver.
- Cracked pavers in the field, not just at the edge. Cambridge pavers are rated for 8,000+ psi compressive strength. A cracked field paver almost always means a void in the sand bed underneath, not a product defect.
- Efflorescence that keeps returning. White chalky film that comes back after cleaning is moisture wicking up through the paver. Cambridge’s ArmorTec treatment resists efflorescence better than most, but no paver stops groundwater. If it keeps coming back, there’s a drainage issue under the field.
- Wobbling or rocking underfoot. Loose, rocking pavers on a walkway to an addition or ADU mean the bedding layer is spent. This gets worse fast, and it’s a code issue for ADU access in Fort Worth if the path to the entrance isn’t stable.

Every price we give is in writing before we start. That’s The Garrison Standard, and it’s not optional. The written price includes the demolition, base work, paver materials from Cambridge, edge restraints, joint sand, and cleanup. The 365-Day Done Right Promise covers the completed work for a full year. If a paver settles or cracks inside that window, we return and correct it at no charge. Most contractors in this market won’t put that in writing. We’ve been doing it since 2004 through the Garrison Partners family.
DIY or Call Us?
You can safely identify your Cambridge paver by flipping it and reading the mold stamp. You can check for obvious settling with a level. That’s where the safe homeowner work ends. Lifting and re-bedding pavers against a new addition’s foundation means cutting the base right, compacting in lifts, and matching the existing color blend. A wrong pitch sends water toward the slab instead of away, and Fort Worth’s clay makes that mistake expensive. If the failure is under a structure or ties into ADU drainage, don’t touch it. We stock Cambridge-compatible edge restraints, joint sand, and base material on the truck. Call (682) 204-4897 and we’ll put eyes on it.
FAQs
Cambridge Pavers with a properly compacted base can last 30 to 40 years in Fort Worth, though the Texas clay and summer heat mean the base typically needs re-compaction every 15 to 20 years while the pavers themselves keep their color and integrity. The ArmorTec surface treatment resists fading better than an unsealed paver. What shortens paver life here is not the product, it’s the water and soil movement underneath it. Call (682) 204-4897 for a free evaluation of your base.
Yes, if the failure is localized to a settling edge or a small washout, we can pull the affected section, re-compact the base, and reinstall the same pavers, which typically costs less than a full replacement and we can match the existing blend from the mold stamp. If the base is failing across the entire field, repair buys you a year at best, and we’ll tell you that straight before quoting anything. Call (682) 204-4897 and we’ll tell you which one you have.
A paver patio or walkway replacement around an addition usually takes 3 to 5 working days in Fort Worth; a full addition or ADU with integrated hardscape runs 8 to 16 weeks depending on permitting and foundation work. We sequence the paver work with the foundation and drainage so there’s no waiting between trades. Call (682) 204-4897 and we’ll give you a written timeline with the price.
We stock common Cambridge paver sizes and edge restraints on the truck for fast repair work, and we order full pallets from regional Cambridge distribution for addition and ADU projects so the color blend stays consistent from day one. Cambridge product runs vary slightly by production date, so we order the full job at once rather than adding on later and risking a color mismatch. We also stock and install materials from KraftMaid, Cambria, and Silestone for the interior side of addition and ADU work, so one scope covers the whole build. Call (682) 204-4897 to get your written price.
