Round Rock and the ground under it
Round Rock is a big Williamson County city north of Austin, with an aging center and plenty of 1990s-2010s subdivisions.
Slabs in Round Rock are constructed on clay that changes volume with moisture, so every home moves slightly through the year. None of this is a finding about a foundation. A leak is a plumbing problem, and foundation questions go to a foundation contractor.

What is under Round Rock floors
Round Rock has homes from a number of decades, so what is under a given floor depends on when it was built. One of the first questions from a crew in Round Rock is what you have already looked at.
Copper wears where it rubs a hard edge as the ground moves. Polybutylene tends to fail at fittings. PEX typically leaks at a single point.
In Round Rock, what steers a repair is where the leak is, how many have occurred and what sits above the line. Phones are answered around the clock for Williamson County calls.
What tends to show first
The usual first signs of a Round Rock slab leak are a warm spot, a higher bill, a hiss at night or a water heater that keeps running. For mixed-age homes on expansive clay, this is one of the first things a crew asks about.
A wet baseboard is not always near the leak, because water moves under the slab and comes up where it can. The cause is confirmed by a technician, and finding the leak always comes before opening a floor.

Round Rock specifics
Newer subdivisions grew quickly here. A leak in a home that new is more frequently a single fitting or a damaged spot than general wear. This site does not advise on warranties. It locates leaks and connects you with a crew.
Large trees along older streets are part of the picture. Roots reach well beyond the canopy. Roots can also enter and block drain lines. That is a drain-clog topic this site does not cover.

How a Round Rock leak is located
The technician isolates lines one at a time and pressure tests them, which tells which line to search. Acoustic equipment next listens along the Round Rock floor for escaping water, and thermal imaging can show a warm path under tile or wood.

Your first move
Turn off everything that uses water, including the ice maker and any irrigation, and watch the Round Rock meter’s leak indicator or low-flow dial for a few minutes.
If the Round Rock floor is wet, close the main if it is safe, protect valuables and call. Do not try to open the floor yourself. See water meter leak check. In Williamson County, crews plan the visit around what you describe on the call.

Round Rock on both sides of I-35
Round Rock grew rapidly from the 1980s onward, and most of its neighborhoods were built in the 1990s and 2000s. The old town near Brushy Creek and the historic downtown has the oldest homes. The city sits on a geological line: land east of I-35 is mostly Blackland Prairie clay, while the west side moves toward the limestone of the Edwards Plateau. That difference affects how much a slab moves with the seasons.
Round Rock's water utility manages meters and billing, with supply from Lake Georgetown and Stillhouse Hollow Lake. Meters are usually near the curb. Water in the area is moderately hard. Homes from the 1990s may have copper or a mix, while most newer homes use PEX.
On the clay side, slabs swell and shrink with moisture, and older copper lines can wear where they meet concrete. On the limestone side, soil movement is usually less, but rock close to the surface can make repair openings slower. Nearly every home has irrigation, so shut it off before checking the meter. When you call, say which side of I-35 you are on, when the house was built and whether you have seen a warm spot, a higher bill or both.
Planning a leak visit in Round Rock
Someone answers Round Rock calls around the clock. A minute or two describing the problem is usually enough for a Williamson County crew to plan the trip. The person answering a Round Rock call asks for the location, the signs and when they started. That short conversation is how a Williamson County crew decides what to bring.
Crews that also cover Hutto and Austin plan their routes around urgent calls first, so describe the situation plainly.
