Foundation Leveling Burnet, TX.

What the ground under a Burnet slab is actually doing

Burnet sits in the heart of the Llano Uplift, and that geology shows up under almost every foundation in town. Exposed Precambrian granite outcrops sit beside fractured Edwards and Ellenburger limestone, with only thin, rocky residual soil in between. The result is some of the most variable bearing ground in Central Texas, and it behaves nothing like the deep Blackland clay you find east of the Balcones Escarpment.

Because of that, the problem here is usually uneven bearing, not uniform shrink-swell. One corner of a house may rest on a granite boulder that barely compresses, while ten feet away a footing spans a shallow clay pocket or a solution-weathered limestone seam that opens up over decades. That contrast in stiffness is what cracks the drywall, racks the doors, and slopes the floor, and it tends to show up in one part of the structure rather than across the whole slab.

Diagnosing it takes a different mindset than a clay-dominated lot. Instead of chasing a seasonal moisture cycle, we're looking for where the footing lost consistent support. Pressed-concrete piers are a poor fit for this terrain: a fixed-length pier can terminate on a weathered limestone shelf instead of sound rock, leaving the repair anchored to material that can still migrate. Steel driven to hydraulic refusal doesn't have that ambiguity, it stops only when resistance meets the engineered threshold, whether sound rock is at six feet or eighteen.

How we level, measure, drive, lift, and prove it

Every project opens with a free elevation survey of the structure, mapped to ±0.01 in. (1/64 in.). On Burnet's terrain that survey usually reveals a non-uniform settlement pattern, a clear tell that the slab is reacting to localized bearing differences, not a whole-structure volume change. The contour map drives the pier layout: placement is calibrated to where load concentrates and where the geology makes anchor depth uncertain, never dropped in on a formula.

From there we set galvanized steel piers, driven hydraulically until they refuse against load-bearing strata, then transfer the structure's weight onto steel and recover the target elevation set by the survey. When the lift is done we re-survey, so the result is documented rather than eyeballed from where the cracks happened to show.

Most Burnet projects land between $4,500 and $14,000, depending on pier count, access, and whether drainage work is warranted. The free survey sets a measured, fixed scope before anything is mobilized, the work carries a lifetime transferable warranty, financing is available, and nearly every home stays occupied while crews work from the exterior and access points.

What we check before quoting a Burnet foundation

A few things on this terrain that separate a lasting repair from a short-lived one:

• The settlement pattern. Doors binding on one side, cracks radiating from a single corner, or floors sloping toward one wall point to localized bearing failure, typical where bedrock depth jumps over short distances.
• Surface drainage. Even on rocky ground, water that ponds against the slab saturates residual clay pockets under the footings. We target 6 inches of fall over the first 10 feet away from the structure.
• Pier-and-beam framing. Older Hill Country homes often sit on cedar or rough-sawn pine beams that have dried and shrunk. Beam deterioration can look identical to settlement from inside but needs different remediation.
• Recent or planned grade changes. New irrigation, retaining walls, or fill alter the moisture environment around footings, thin rocky soil holds more water than it looks like it should, so a baseline survey documents conditions first.
• Where water concentrates after a storm. Rain sheets across impermeable granite and limestone and collects at low points, often right where the footings sit; grading and downspout work get evaluated as part of the written plan.
