University Park Sits on Old Chalk With Even Older Homes
University Park is one of the most desirable addresses in Texas, and one of the hardest on foundations. The entire city sits on the Austin Chalk formation — a layer of Cretaceous-era limestone and marl that runs beneath the Park Cities west of the White Rock Escarpment. Chalk sounds stable, and compared to the Eagle Ford clay on the east side of Dallas, it is. But “more stable” doesn’t mean trouble-free. The topsoil above that chalk is loaded with pockets of reactive clay that still swell and shrink with the seasons. And the chalk itself erodes underneath a slab over decades, creating voids that let sections of a foundation drop.
The bigger issue in University Park is age. This city was incorporated in 1924, and most of the original housing stock went up between the late 1920s and early 1950s. Neighborhoods like Windsor Place, Volk Estates, and the streets surrounding SMU are full of homes that are 75 to 100 years old. Even the ones that have been gut-renovated usually kept the original slab. A foundation poured in 1938 wasn’t engineered for the loads and soil stresses we understand today. Add decades of oak and pecan root systems pulling moisture out of the clay, and you get slabs that have moved significantly.
Our Dallas office is about 15 minutes north at 14875 Preston Rd, Suite 550. We run crews through University Park regularly — the Park Cities are one of our busiest service areas. Every inspection starts with elevation readings across your full slab, a drainage and grading check, and a soil assessment on all four sides. Everything goes in a written report. If your foundation doesn’t need piers, we’ll tell you. We have completed over 20,000 inspections in the DFW area and walked away from plenty of jobs that didn’t require repair. When work is needed, we match one of our three engineered pier systems to your specific soil conditions and get most jobs done in a single day.
University Park covers just over 3.7 square miles, but the foundation conditions are remarkably consistent across the city. The entire area sits on the Austin Chalk formation, with a varying layer of residual clay on top. That clay is thinner here than the deep Eagle Ford deposits east of the escarpment, but it’s still reactive enough to cause real movement — especially when large trees dominate the lot, which they do in most of University Park.

Austin Chalk Erosion
The Austin Chalk beneath University Park is a soft limestone that weathers slowly but steadily. Over 50 to 100 years, water dissolving through the chalk creates small voids beneath a slab. When a section of the foundation loses support from below, it drops. This is a different failure mechanism than clay heave — it’s quieter, more gradual, and often missed until the settlement is significant.
🌳
Mature Tree Root Systems
University Park is a tree-covered city. Live oaks, pecans, and elms with canopies spanning 60 feet or more are everywhere. Those root systems pull enormous amounts of moisture from the clay layer under and around a foundation. During a dry summer, the soil on the tree side of a home can shrink dramatically while the opposite side stays wetter. That imbalance is one of the most common causes of differential settlement we see in the Park Cities.

Pre-War and Post-War Slab Construction
Many University Park foundations were poured between the late 1920s and 1950s. Some of the oldest homes along streets like Purdue, Haynie, and McFarlin sit on slabs with minimal steel reinforcement by today’s standards. Even homes built during the 1940s and 1950s expansion used thinner wire mesh and shallower beam depths than modern code requires. Eighty years of soil cycling eventually catches up.
🔄
Tear-Down Rebuilds on Original Pads
University Park has seen a wave of tear-downs over the past two decades. A 1940s cottage gets demolished and a 5,000-square-foot home goes up on the same lot. Sometimes the builder pours a new slab. Sometimes they build on the existing pad or a modified version of it. Either way, the new home puts significantly more load on soil that has already been cycling for 80 years. We’ve repaired homes that were only five years old because the new structure overwhelmed the ground beneath it.
Drainage is also a factor, especially on the smaller lots closer to SMU where homes sit tight against each other. If your neighbor’s lot drains toward your foundation, or your downspouts dump water at the slab line, that accelerates everything. We evaluate drainage during every free inspection.
Signs Your University Park Home May Need Foundation Repair
In older Park Cities homes, some of these warning signs have been present for years and get written off as “character.” They shouldn’t be. If you’re seeing two or more, it’s worth getting elevation data on your slab.
→Diagonal cracks in plaster or drywall radiating from door and window corners
→Doors that stick, drag, or won’t latch, particularly interior doors that used to close easily
→Stair-step cracking in exterior brick mortar joints, common on the side of the home nearest large trees
→Floors that slope noticeably when walking from the center of the home toward a perimeter wall
→Gaps opening between crown molding and ceilings or between built-in cabinetry and the wall
→Windows that no longer open or close smoothly, especially original wood-frame windows in older homes
A single crack in a 90-year-old home doesn’t automatically mean the slab is failing. Plaster cracks as it ages, and some settling is normal over that kind of time frame. What matters is whether your slab is actively moving or has moved far enough to cause structural concern. We measure that with elevation data across every square foot of your foundation.

Recent University Park Project
Lovers Lane Area, Built 1947
A homeowner on Greenbrier Drive contacted us after noticing that the front door had started dragging against the threshold and a long diagonal crack had opened in the living room plaster near the fireplace. The home was a 2,800-square-foot Tudor built in 1947 on Austin Chalk with a thin clay cap. Two large live oaks on the south side of the property had been drawing moisture from under the slab for decades.
Our elevation survey revealed 1.75 inches of settlement along the entire south perimeter, with the deepest drop at the southeast corner closest to the larger oak. We installed 14 ST1 piers along the south and east walls, lifted the slab back to within a quarter inch of level, and finished by early afternoon. Total cost was $5,200. The homeowner called the next morning to say the front door was closing flush for the first time in years.
Every University Park home sits on slightly different ground, and the right pier system depends on what’s happening beneath your specific slab. We carry three systems and your inspector will recommend the one that matches your soil depth, clay reactivity, and the weight of your home.
Most Affordable
ST1 System
Concrete Pressed Piers
Starts with 1 ft of steel, then all concrete. 11,980 PSI cylinders, nearly 2x stronger than the industry standard. A strong fit for University Park homes where the Austin Chalk sits relatively close to the surface and the clay layer above it is thin and stable.
Starts with 3 ft of steel, then concrete. Reaches about 50% deeper than the ST1 and punches through shallow hard layers. This is our most common choice for University Park repairs, especially on lots where mature trees have dried the clay and created unpredictable resistance near the surface.
Starts with 10 ft of double-walled steel, reaching about 2x the depth of the ST1. Reserved for the most severe settlement, particularly on larger University Park homes where a tear-down rebuild added significant load to compromised soil. Also used when chalk erosion has created deeper voids that shallower piers can’t bridge.
Most University Park jobs finish in a single day. Our crew excavates at each pier location along the perimeter, drives the pier to refusal, and lifts the slab back toward its original position. Steel brackets lock everything in place. Every hole is backfilled and compacted before we leave. You can stay in the home during the entire process — no need to relocate.
Your free lifetime transferable warranty starts the day we finish. If you sell your home, the warranty transfers to the new buyer at no cost. We also offer 0% interest financing with 6, 12, or 24-month terms and no payments required.

Foundation Repair FAQs — University Park
Most University Park foundation repairs fall between $2,500 and $15,000. The final cost depends on how many piers your home needs and how far the slab has settled. We offer 0% financing for up to 24 months with no payments.
University Park sits on the Austin Chalk formation with reactive clay in the topsoil. Much of the housing stock dates to the 1920s through 1950s, meaning slabs are 70 to 100 years old with reinforcement that falls short of modern standards. Mature tree root systems pull moisture unevenly from the soil, and decades of chalk erosion create voids beneath foundations. Newer tear-down rebuilds also add heavy loads to aging ground.
Diagonal cracks in plaster or drywall near door and window corners. Doors that stick or drag when they used to work fine. Stair-step cracks in exterior brick mortar joints. Floors that slope from room to room. Gaps between crown molding and ceilings or between cabinetry and walls. Windows that no longer open or close smoothly, especially original wood-frame windows.
Yes. Every inspection is free with no obligation. We take elevation measurements across your entire slab, evaluate drainage and grading, and assess soil conditions on all four sides. You receive a written report with our findings. If your foundation does not need repair, we will tell you. Our nearest office is at 14875 Preston Rd Suite 550 in Dallas, about 15 minutes from University Park.
Most repairs finish in a single day. The crew excavates at each pier location, drives the piers to refusal, and lifts the slab back toward level. Steel brackets secure everything in place. All holes are backfilled and compacted before we leave. You do not need to move out during the repair.
We install three systems: the ST1 (concrete pressed piers, most affordable), the ST3 (steel and concrete hybrid, our most-installed system in University Park), and the ST10 (deep steel piers for severe settlement or deeper soil problems). Your inspector selects the right one based on your soil conditions, home weight, and the extent of movement.
