Commercial Concrete in Schertz: Parking Lots to Foundations
Commercial concrete in Schertz operates in one of the most active business corridors in the San Antonio metro. The I-35/I-10 interchange puts Schertz at the geographic center of a triangle connecting San Antonio, Austin, and Houston — and that position drives commercial development in Selma’s retail hub, along the FM 3009 corridor, and in the industrial areas east of I-35. Businesses in these areas need concrete that meets higher specifications than residential work, handles heavier traffic loads, and meets ADA compliance requirements that residential concrete does not.
In this post, we cover the concrete specifications required for different commercial applications in Schertz, the local conditions that affect commercial concrete performance, permit requirements, and how to plan a commercial concrete project around business operations.

Why Commercial Concrete in Schertz Is Different
The same Guadalupe County clay soils that affect residential concrete also affect commercial slabs — but the consequences of failure are more disruptive in commercial settings. A parking lot slab that settles from clay soil movement requires lane closures and creates liability risk from trip hazards and vehicle damage. A loading dock slab with joint failure creates operational problems for forklifts and deliveries.
Commercial concrete in Schertz also faces higher specification requirements: minimum 6-inch slabs for most commercial applications (vs. 4 inches for residential), higher PSI concrete mixes (4,000–5,000 PSI vs. 3,000–3,500 PSI), and rebar reinforcement with tighter spacing than residential applications. These requirements are not arbitrary — they reflect the real load and traffic conditions that commercial surfaces experience.
Commercial Concrete Applications in Schertz
Parking lots: The most common commercial concrete project in Schertz and Selma. Standard parking lot spec: 6-inch slab, 4,000 PSI concrete, #4 rebar on 18-inch spacing. Expansion joints every 20–25 feet. Drainage design is critical — parking lots are large impervious surfaces and must direct water to drainage structures, not toward buildings or adjacent properties.
Loading docks and truck aprons: Among the most demanding commercial concrete applications. Heavy semi-truck loads require 8-inch or thicker slabs with 4,500–5,000 PSI concrete and steel fiber reinforcement for impact resistance. Joint details at the dock edge must be tight to prevent forklift edge spalling.
ADA-compliant sidewalks and ramps: ADA requirements specify minimum widths, maximum cross-slopes (2 percent maximum), surface texture for detectable warning strips at transitions, and slope requirements for accessible routes. Commercial renovations often trigger ADA compliance requirements that require updating existing sidewalk and ramp configurations.
Equipment foundations and pads: Generators, HVAC equipment, and mechanical units require concrete pads engineered for the specific equipment load. PSI specifications and thickness depend on equipment weight and vibration characteristics.
Dumpster pads: Dumpster pads take repeated heavy-load impacts and need to be built accordingly — minimum 6-inch concrete with rebar to handle the structural demands that regular container service creates.
Drive approaches and curb cuts: Commercial drives entering from public streets must meet city standards for width, slope, and clearance. Permits and city inspection are required for any work in or adjacent to the public right-of-way.
Commercial Concrete Specifications for Schertz Clay Soils
Right Specs for Guadalupe County Commercial Concrete
We specify concrete PSI, slab thickness, and reinforcement based on your actual load conditions and local soil — not generic templates.
Commercial concrete on Guadalupe County clay requires attention to base prep beyond what residential work demands. Key commercial spec considerations:
Base preparation: Minimum 6-inch compacted aggregate base for parking lots on clay soils. Some applications benefit from lime stabilization of the top 6 inches of native clay before placing aggregate — this chemically alters the clay to reduce its expansion and contraction properties.
Concrete PSI: Standard commercial parking lots: 4,000 PSI. Loading docks and heavy-duty applications: 4,500–5,000 PSI. Higher PSI concrete has lower water-cement ratio, which produces denser, less permeable concrete that handles both load and moisture better.
Rebar: Commercial parking lots use #4 rebar (1/2”) minimum on 18-inch centers. Loading docks and heavy-duty areas use #5 rebar (5/8”) or steel fiber reinforcement. Fiber alone is not adequate for commercial vehicle load applications.
Joint design: Commercial control joints in parking lots should be spaced at 12–15 feet on center — tighter than the 10–12 feet typical for residential work — because the larger slab areas and heavier loads require more joint locations to manage thermal and clay-movement cracking.
Permitting for Commercial Concrete in Schertz
Commercial concrete work requires City of Schertz building permits for all new flatwork and significant repair. Commercial projects typically require:
- Building permit application
- Site plan showing property boundaries, existing structures, and proposed concrete areas
- Civil engineering drawings for larger projects
- Stormwater management documentation if impervious coverage is being added
- ADA compliance documentation for accessible route work
Projects near public rights-of-way — drive approaches, adjacent sidewalks — may also require Schertz Public Works review. We coordinate with the appropriate departments and handle permit submission as part of our commercial project process.
Scheduling Commercial Work Around Business Operations
The biggest challenge in commercial concrete is minimizing disruption to ongoing business operations. Strategies we use for Schertz commercial projects:
Phased pours: For parking lots, we section the lot and pour in phases, keeping other sections accessible during each phase. Traffic management cones and signage direct customers during active pour areas.
After-hours and weekend work: For businesses where any daytime closure is unacceptable, we schedule concrete work during off-hours. Extra costs for night or weekend labor are outweighed by the business impact of full-day closures for operations like gas stations, restaurants, and retail.
Sequential planning: When multiple concrete elements are being added — parking lot plus dumpster pad plus sidewalk — planning the sequence to keep the most critical access areas open longest reduces operational disruption.
Frequently Asked Questions
How much does commercial parking lot concrete cost in Schertz?
Standard commercial parking lot concrete in Schertz runs $5–$7 per square foot for 4-inch slabs and $7–$10 per square foot for 6-inch commercial-spec slabs. Loading docks and heavy-duty surfaces with thicker slabs and heavier reinforcement cost $10–$15+ per square foot. Prices reflect local Schertz market conditions and clay soil base prep requirements. See our commercial concrete service page for full detail.
Do I need engineering drawings for commercial concrete in Schertz?
For smaller projects — dumpster pads, minor sidewalk extensions — engineering drawings may not be required. For larger parking lot installations, drive approaches on state or county roads, and projects in areas with stormwater management requirements, engineering drawings are typically required by the permit process. We help determine what documentation is needed for your specific project during the pre-permit review.
How do I schedule commercial concrete while staying open for business in Schertz?
Phased pours are the most common approach — we work through your parking lot or site in sections, keeping other areas accessible. After-hours and weekend scheduling is available for critical operations. Contact us to discuss the specifics of your business hours and access requirements so we can develop a phasing plan before work begins.
