Cambridge Pavers Home Additions & ADU: The San Antonio Owner’s Guide
When you’re planning a home addition or ADU with Cambridge Pavers in San Antonio, you’re typically looking at $45,000 to $130,000 for a full build, depending on square footage, foundation work, and how much of the Cambridge product line you’re incorporating into hardscape and outdoor living areas. Most homeowners reach out to us after their existing space stops working: the paver patio drains toward the house, the retaining wall has shifted, or the original installer used an incompatible base material under Cambridge Pavers and now the surface is heaving.
We stock Cambridge Pavers-compatible materials and install additions and ADUs throughout San Antonio. Whether the failing part is a paver section, an edge restraint, or a larger structural issue tied to the addition itself, you’ll get a written price before any work starts, and a crew you can identify by name and photo before they ever step on your property. That’s the whole job before the job starts.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers produces several lines that show up regularly in San Antonio additions and ADU projects, and the compatibility details matter more than most homeowners expect. The Ledgestone and RoundTable collections are the two we encounter most often on ADU patios and perimeter walkways. They use different joint widths: Ledgestone is built for tight, 1/8-inch joints and looks right when the pattern locks closely, while RoundTable’s rounded edges demand a wider 1/4-inch to 3/8-inch joint to avoid chipping at the contact points.
Here’s the compatibility gotcha we see on San Antonio jobs: Cambridge color lots vary by region, and the “Onyx Black” paver you bought in 2019 may not match the “Onyx Black” produced in the current run. If you’re repairing a section of an existing patio rather than building new, we always recommend pulling a sample from the existing installation and matching against it directly. We’re an independent service provider and not affiliated with Cambridge Pavers, but we work with their material daily, and we know what the Austin and Dallas regional lots look like compared to what’s typically available in San Antonio supply yards.
For an ADU or addition, the decision between OEM Cambridge Pavers and a quality aftermarket equivalent is usually simpler than homeowners fear. Cambridge’s proprietary ArmorTec surface treatment is hard to replicate in aftermarket products, particularly on high-traffic walkways. But for under-structure fill and base materials, we regularly use ASTM-spec crushed limestone sourced locally in Bexar County, which is the right product for our expansive clay soils and costs less than a branded alternative with identical performance.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing
- Pavers are sinking or heaving in a defined pattern. This is almost always a base failure, not a paver failure. In San Antonio, the culprit is typically the clay soil expanding and contracting through our wet-dry cycles, which is why the base prep matters more than the paver itself.
- Joint sand is washing out after every rain. If you can see gaps widening between pavers and a fan of sand spreading across the surface after a storm, the edge restraint has failed. Once the perimeter releases, the whole field starts moving.
- Water pools against the foundation after a heavy rain. A Cambridge paver patio that pitches toward the house instead of away from it is a drainage problem and a foundation risk in one. This happens when the original installer didn’t account for San Antonio’s fast, hard downpours.
- The retaining wall is leaning or cracking at the corners. Cambridge wall block is built to last, but no wall survives bad geometry. A leaning section means the deadman anchors or the drainage behind the wall weren’t done right, and that’s a structural issue, not a cosmetic one.
- You can feel movement underfoot when you walk across the surface. A properly installed paver field shouldn’t shift. Any wobble or soft spot means the base has lost compaction, and leaving it alone only accelerates the damage.

You’ll know the cost of the pavers, the base work, the structure, and the labor as separate numbers.

DIY or Call Us?
A homeowner can safely inspect the obvious: look for joint sand washing out, check if the surface drains toward the house, and mark any paver that wobbles underfoot. Those observations help you describe the problem accurately when you call. Where DIY goes wrong is when someone tries to reset pavers on a failed base. If the base has lost compaction or the edge restraint has released, resetting individual pavers is cosmetic work on a structural problem, and it will fail again within a season. San Antonio’s clay soil punishes shortcuts.
If the failure involves a retaining wall, do not attempt to disassemble or rebuild it yourself. A wall holding back several tons of soil can shift suddenly during teardown, and that’s a serious injury risk. That’s contractor work, full stop.

FAQs
A properly installed Cambridge Paver surface in San Antonio should last 25 to 40 years on the surface, but only if the base was built right. What fails first in our climate is usually the base or edge restraint, not the paver itself. Call (254) 269-5071 if you’re seeing movement or drainage issues, and we’ll tell you what’s actually going on.
Yes, if the failure is isolated to one section and the base is still solid underneath. We can lift and reset a localized area, re-compact the base, and match the existing pavers. If the base has failed across the whole field, partial repair just delays the full fix. A site visit will tell you which situation you have, and the estimate is free.
A typical addition runs 4 to 8 months from permit to final walkthrough, and an ADU runs 6 to 12 months, with San Antonio’s permitting timeline and weather both playing a role. We put the schedule in writing alongside the price so you know what to expect before we break ground. Call (254) 269-5071 for a free estimate on your project.
We source Cambridge Pavers directly through our supplier relationships and handle the full material order, including color-lot matching against any existing installation on your San Antonio property.
