H&M New Braunfels Concrete Works serves San Marcos with stamped concrete, driveways, patios, and foundations, and we understand the Blackland Prairie clay soils and Hill Country rock that make concrete work here different from anywhere else. We respond within one business day.

San Marcos homeowners near the historic downtown and the Hill Country edge often want surfaces that look as good as the surroundings - without the upkeep of natural stone or pavers. Our stamped concrete services create custom patterns for driveways, patios, and pool decks that hold up in the Texas Hill Country climate.
Concrete is the standard for residential driveways in San Marcos, and the clay soils on the east side of the city make the quality of the subgrade prep more important than almost anywhere else. We build driveways designed to handle soil movement without cracking prematurely.
Outdoor space matters in San Marcos, where mild winters and long springs make a backyard patio usable for more of the year than in most parts of the country. A concrete patio built with the right drainage slope keeps water away from the structure during the area's heavy spring rain events.
San Marcos has sloped properties on the Hill Country side of town and low-lying areas near the San Marcos River that need grading and erosion control. Concrete retaining walls provide lasting stability in both conditions and hold up better than timber in the wet-dry cycles that characterize the local climate.
New construction in San Marcos's growing northern and eastern subdivisions requires slab foundations suited to the local soil. The Blackland Prairie clay in those areas expands and contracts with moisture, so post-tensioned or reinforced slab designs are often more appropriate than a basic monolithic pour.
The commercial corridor along I-35 through San Marcos sees constant vehicle traffic, and concrete parking lots hold up better than asphalt under that kind of sustained use. We build and resurface commercial lots for retail, restaurant, and light industrial properties along the corridor.
San Marcos sits right at the edge between two very different soil environments. The western and hillier parts of the city sit on thin soil over limestone, where digging a few feet hits rock and drainage runs fast. The eastern parts of the city, including many of the newer and faster-growing subdivisions, sit on Blackland Prairie clay. That clay shrinks to a hard crust in a dry summer and swells back up when the rains return. Every wet-dry cycle puts pressure on whatever concrete is sitting on top of it - driveways, sidewalks, patio slabs, and foundations all feel that movement over time. A contractor who knows which side of town they are working on, and who prepares the subgrade accordingly, produces work that lasts years longer than one who uses the same spec everywhere.
The heavy university presence in San Marcos also creates a concentration of rental properties near Texas State that turn over tenants regularly and often need exterior work between leases. Driveways, walkways, and patio areas in those neighborhoods see more foot traffic than average residential properties, and the deferred maintenance typical of rental housing means repair and replacement jobs are common. Across the commercial corridor on I-35, heavy truck traffic wears pavement surfaces faster than in residential areas, creating steady demand for parking lot and flatwork repair. According to the USGS, the Blackland Prairie soils that dominate the east side of San Marcos are among the most expansive in the country, making subgrade preparation the single most important factor in how long concrete flatwork lasts here.
Our crew works in San Marcos regularly, and we understand the local conditions that affect concrete work here. San Marcos is the county seat of Hays County, served by the City of San Marcos development services department for permits, and the city has specific requirements for work near its flood-prone areas - particularly properties near the San Marcos River and low-lying drainage channels. We know how to identify those situations early and factor the right drainage design into jobs before work begins, not after problems show up.
San Marcos is a city divided by its geography and by its population. Ranch Road 12, State Highway 80, and I-35 are the main routes that connect the older downtown and university neighborhoods to the newer residential areas spreading north toward Kyle and east toward Lockhart. Working across those different neighborhoods - from the older streets near the courthouse square to the brand-new subdivisions where concrete is going in for the first time - gives us a realistic picture of what San Marcos properties actually need. We also regularly serve nearby communities including Wimberley to the west and Kyle to the north.
Call or use our contact form and we will get back to you within one business day. We work around your schedule for the site visit.
We come out and look at the site in person - soil type, drainage slope, access, and any existing concrete. This is where we address your cost questions and set clear expectations before you commit to anything.
We prepare the subgrade correctly for San Marcos soil conditions, set forms, and pour. Summer pours are timed for morning hours and use curing methods that protect the slab in high heat.
We leave the site clean and walk you through curing timelines before we go. You will know exactly when the surface is ready for foot traffic and when it is ready for vehicles.
We serve all of San Marcos, TX - from near Texas State to the newest subdivisions on the edge of town. No obligation, just an honest assessment.
(830) 402-1980San Marcos is the county seat of Hays County, located roughly halfway between Austin and San Antonio along the I-35 corridor. The city has grown well past 60,000 residents and has been one of the fastest-growing cities in the United States for over a decade. Texas State University, one of the largest universities in Texas, sits in the heart of the city and shapes both its character and its housing stock. The neighborhoods closest to campus have a mix of older single-family homes, duplexes, and apartments that see frequent tenant turnover. Farther from the university, newer subdivisions have spread outward in all directions, particularly to the north toward Kyle and to the east.
The San Marcos River, a spring-fed river known for tubing, kayaking, and clear water, runs through the city and is a defining local feature. Properties near the river and in low-lying areas are in recognized flood zones and face drainage challenges that inland properties do not. The historic downtown centered on the courthouse square gives the city a distinct sense of place, and that older core sits alongside the fast-growing residential areas that have made San Marcos one of the most active construction markets in Central Texas. We also serve the nearby communities of Wimberley and Seguin.
