Commercial Concrete Contractor
In San Antonio, TX
The Short Answer
Concrete Is Where We Started
GRAMS Construction, LLC self-performs commercial concrete and sitework in San Antonio, Texas: engineered foundations, structural slabs, grade beams, stem walls, commercial paving, curbs and approaches, equipment yards, heavy-duty flatwork, and grading and drainage. We work directly for owners and as a concrete subcontractor to general contractors.
Michael and Rudy Ramirez learned formwork, placement, and finishing working alongside their father, then spent years on heavy industrial sites along the Texas Gulf Coast where tolerances are tight. GRAMS brings that standard to every pour.
Every pour is built to engineered specifications: reinforced beams, compacted base, vapor barriers, and finish tolerances that hold up under Texas soil and Texas weather.
Concrete Scopes We Self-Perform
- Structural slabs and engineered foundations for metal buildings, warehouses, and commercial shells.
- Perimeter stem walls and grade beams, including anchor bolt layouts set to the frame design.
- Commercial paving, curbs, and approaches for parking, drive lanes, and site access.
- Equipment yards and heavy-duty flatwork built for truck and equipment loads.
- Walkways, patios, and site concrete.
- Grading, drainage, and storm-water scope tied into the paving and building pad.
Why Soils Matter In San Antonio
Much of the San Antonio region sits on clay soils that swell when wet and shrink when dry. On a commercial slab, that movement shows up as cracking, doors that bind, and drainage problems. The fix is engineering, not extra concrete: a geotechnical report, a foundation designed to it, proper subgrade preparation and compaction, moisture control, and correctly placed joints. GRAMS builds to the engineer's specification and documents the work in place with daily logs and photos.
Permits For Commercial Concrete
Inside the city, a foundation is part of the commercial building permit issued by Development Services through BuildSA. The City of San Antonio permit process lists flatwork as its own trade permit, linked to the parent building permit. For larger projects, the city's phased permitting lets site work and foundations start in their own phase before the full building is approved.
