Lowry Crossing Sits on Some of the Deepest Clay in Collin County
Lowry Crossing is about six miles southeast of our McKinney headquarters on Custer Road. It’s a small town — under 2,000 people — but we’ve been out there plenty. The community sits right along Farm Road 546 near the East Fork of the Trinity River, and the soil in that river corridor is some of the heaviest Blackland Prairie clay in the county. Homes on the larger lots that define Lowry Crossing deal with the same foundation issues as the rest of Collin County, but the low-lying terrain near the East Fork makes drainage problems worse.
If your doors are sticking, your brick has stair-step cracks, or your floors feel uneven when you walk across a room, your slab is probably moving. The clay under Lowry Crossing can contain over 60% smectite, which means it swells significantly when it absorbs moisture and contracts hard during a dry summer. That constant push and pull is what breaks slabs over time. But not every crack means you need piers. We see plenty of homes where what looks alarming is just normal concrete curing or minor settling.
We offer a free inspection with no obligation. Our crew drives out from McKinney, takes elevation readings across your entire slab, checks your grading and drainage, and evaluates the soil conditions around your home. Everything goes into a written report. If you don’t need piers, we’ll tell you straight. We have done over 20,000 inspections across DFW and walked away from a lot of jobs that didn’t need repair. When your home does need work, we use one of our three engineered pier systems and get most jobs done in a single day.
Lowry Crossing sits squarely in the Blackland Prairie, the geological band of dark, high-plasticity clay that runs through central Collin County. The town’s position near the East Fork of the Trinity River means the clay here tends to be deeper and wetter than what you find on the higher ground closer to McKinney or Princeton. That combination — deep clay with a high water table nearby — creates conditions where foundations take a beating over time.

Blackland Prairie Clay
The soil under Lowry Crossing is classified as Vertisol — heavy, dark clay with a high smectite content. It can swell dramatically when saturated and crack several inches wide during summer drought. The shrink-swell cycle puts constant pressure on your slab, and homes on the larger acreage lots in Lowry Crossing often have more exposed soil surface around the foundation, which amplifies the effect.

East Fork Trinity River Proximity
The East Fork of the Trinity River runs just south and east of town. Homes closer to that floodplain deal with higher moisture levels in the soil, especially after heavy rain events. The water table is shallower here than on the ridges to the north, which means the clay stays saturated longer. When a drought finally hits, the rapid drying causes sudden, uneven contraction under the slab.
🏠
Acreage Lots and Septic Systems
Lowry Crossing has traditionally been a community of one-acre-plus lots, many with septic systems instead of municipal sewer. A leaking septic line or poorly routed drain field can push moisture into the clay on one side of your foundation while the other side stays dry. That difference in moisture is exactly what causes differential settling — one corner drops while the rest holds.

The 2022 Drought-to-Flood Cycle
The summer of 2022 brought extreme drought across Collin County. The clay under Lowry Crossing dried out completely, forming deep cracks in the ground. Then heavy rain returned in the fall and saturated everything fast. That whiplash — bone-dry to soaked — is the worst thing that can happen to a slab on expansive soil. We saw a spike in inspection requests from this area that year from homeowners who had never noticed a single issue before.
The combination of deep Blackland clay, river-adjacent terrain, and large lot drainage challenges makes Lowry Crossing a high-risk area for foundation movement. Proper drainage and gutter management make a real difference. We check all of that during every free inspection.
Signs Your Lowry Crossing Home May Need Foundation Repair
Some of these develop slowly over years. Others show up after a single dry summer or a heavy rain season. If you notice two or more, it’s time to get a professional look.
→Cracks running diagonally from door or window corners through the drywall
→Interior doors that drag, stick, or refuse to latch when they used to work fine
→Stair-step cracking in exterior brick, following the mortar lines
→Floors that slope or feel uneven when you walk from one room to the next
→Gaps forming between walls and ceilings, or between window frames and the surrounding wall
→Cracks in the garage slab or driveway that weren’t there a year ago
A single hairline crack doesn’t always mean trouble. New slabs crack as the concrete cures, and that’s normal. What matters is whether your slab is actually moving. We figure that out with elevation data across the full footprint of your home. If it’s just cosmetic, we’ll let you know.
Foundation Repair Systems We Install in Lowry Crossing
Recent Lowry Crossing Project
Acreage Home Off FM 546, Built 2003
A homeowner on a one-acre lot south of FM 546 called us about doors that had stopped closing and a visible gap between the garage wall and the ceiling. The home was built in 2003 on deep Blackland clay. Our elevation survey showed 1.75 inches of settlement along the south perimeter, with saturated soil on that side from a septic drain field that had been directing moisture toward the foundation for years.
We installed 14 ST3 piers along the south and east walls, brought the slab back within a quarter inch of level, and finished by early afternoon. Total cost was $5,600. The homeowner said the master bathroom door latched properly for the first time in two years.
Every Lowry Crossing home is different, and the right pier depends on what’s going on underground. We carry three systems. Your inspector will recommend the one that fits your soil depth and your home’s load. How much the slab has already moved factors in too.
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 good option where the Blackland clay is shallower and the home has moderate settling.
Starts with 3 ft of steel, then concrete. Punches through shallow hard layers and reaches about 50% deeper than the ST1. This is our go-to system for Lowry Crossing and the surrounding Collin County area. The deep Blackland clay here usually calls for it.
Starts with 10 ft of double-walled steel, reaching about 2x the depth of the ST1. We reserve this for severe cases where the active clay goes deep. Homes near the East Fork floodplain sometimes need it because the clay stays wet far below the surface.
Most Lowry Crossing jobs wrap up in one day. Our crew digs 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 the whole time.
Your free lifetime transferable warranty starts the day we finish. If you sell your house later, the warranty transfers to the buyer at no cost. We also offer 0% interest financing with 6, 12, or 24-month terms and no payments required.

Foundation Repair FAQs — Lowry Crossing
Most foundation repairs in Lowry Crossing fall between $2,500 and $15,000. The total 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.
Lowry Crossing sits on deep Blackland Prairie clay near the East Fork of the Trinity River. The clay contains high levels of smectite, which swells when wet and shrinks when dry. That constant cycle stresses foundations over time. The proximity to the river floodplain keeps the water table shallow, and when drought hits, the rapid drying causes uneven contraction under slabs. Homes on larger acreage lots with septic systems face additional risks from uneven moisture distribution around the foundation.
Diagonal cracks in drywall near door and window corners. Doors that stick or won’t latch. Stair-step cracks in exterior brick. Floors that slope or feel uneven. Gaps between walls and ceilings or around window frames. Cracks in the garage slab or driveway that weren’t there before.
Yes. Every inspection is free, no obligation. We drive out from our McKinney headquarters, take elevation measurements across your full slab, check your drainage and grading, and evaluate the soil conditions. You get a written report with everything we find. If you don’t need repair, we’ll tell you. Our office is about six miles from Lowry Crossing at 1402 Custer Rd #904 in McKinney.
Most repairs finish in a single day. The crew digs at each pier location, presses the piers to refusal, and lifts the slab back toward level. Steel brackets hold everything in place. All holes are backfilled and compacted before we leave. You do not need to move out.
We use three systems: the ST1 (concrete pressed piers, most affordable), the ST3 (steel and concrete hybrid, our most-installed system in Collin County), and the ST10 (deep steel piers for severe settlement or deep active clay near the East Fork floodplain). Your inspector picks the right one based on your soil conditions and how much movement has occurred.
