Precision concrete coring in San Antonio for utilities, HVAC, and structural testing.
Local Concrete Coring Expertise
In San Antonio, concrete coring drills precise holes through concrete for utilities, HVAC systems, plumbing, and structural testing. Whether you're renovating a downtown loft or expanding a Northside warehouse, accurate coring prevents damage to rebar and existing systems. We combine precision drilling with safety protocols that meet San Antonio building codes.
We start with site evaluation and utility location, then drill to exact specifications using diamond-core equipment. Each hole is verified for depth, angle, and integrity before we clean and restore the work area.
We evaluate the concrete surface, locate embedded utilities with scanning equipment, and mark hole locations to exact specifications.
Our technicians mount the diamond-core drill, secure the rig, and set the anchor depth. Water cooling is applied to manage heat and keep dust down.
Once drilling reaches target depth, the core sample is extracted intact. For structural testing, samples are logged and labeled per your requirements.
We remove debris, clean the work area, and verify hole dimensions against your specifications. Documentation is provided for compliance.
You'll always know what's happening next—and when.
We deliver precision coring for commercial, industrial, and residential projects across San Antonio. Each service is paired with utility location and compliance verification.
Coring holes for plumbing runs and HVAC ducts requires exact sizing to prevent fit issues and water damage. In San Antonio's older neighborhoods like Southtown, concrete slabs often hide rebar and post-tension cables. We scan first, then drill vertical or angled holes to specification.
Holes are drilled level, plumb, or at custom angles. Water cooling prevents thermal shock that can weaken concrete. We verify hole diameter and depth before sign-off.

Electrical conduit and data cabling must route through concrete walls and floor slabs without crossing live utilities. Our scanning identifies conduit runs, rebar, and electrical lines before drilling begins.
We drill precise holes at multiple angles and depths to accommodate bundled cables. Each hole is sized to allow conduit insertion without force, protecting both the cable jacket and concrete edge.
Structural engineers and building inspectors rely on core samples to assess concrete strength, composition, and durability. We extract samples per ASTM standards, label them, and prepare documentation for lab testing.
Common in renovation and renovation projects, core sampling verifies existing concrete quality before repair or load-bearing modifications. North San Antonio commercial builds often require testing before tenant buildouts.

Improper drilling can crack concrete, sever utilities, or compromise structural integrity. Precision coring protects both the existing structure and new systems.
San Antonio building codes require utility location and inspection before penetrating concrete. We perform precise coring to route utilities such as plumbing, electrical conduits, and HVAC systems, minimizing the risk of damage or leaks.
Scanning equipment detects rebar, post-tension cables, and embedded conduit before drilling. Our team is trained in safety protocols to protect workers and the work area. Documentation is provided for city inspections.
Diamond-core drilling is slower than traditional jackhammer work, but it produces clean holes without spalling or edge cracking. This is critical in finished buildings where aesthetics and structural integrity matter.
Holes drilled at angles or depth require precision rig setup and operator skill. We verify every hole against your specifications before cleanup. Mistakes in coring are expensive and time-consuming to repair.
We work throughout San Antonio, from downtown renovation projects to North San Antonio commercial construction, South San Antonio warehouses, and surrounding neighborhoods.
San Antonio's mixed building stock—from historic masonry to modern concrete structures—requires flexibility in drilling approach. Older Southtown buildings often feature thicker concrete and complex reinforcement. Newer commercial parks use lighter slabs with post-tension cables that demand careful scanning.
We've worked on tenant buildouts downtown, HVAC upgrades in residential developments, plumbing retrofits in Alamo Heights area properties, and structural testing for commercial expansion projects across the metro area. Every site presents unique challenges; we adapt our approach to match your concrete type and specifications.
From downtown lofts to North San Antonio logistics facilities, we bring the same precision and safety focus to every job.
Concrete coring (also known as concrete core drilling) is the mechanical process of drilling a precise circular hole in concrete structures such as walls and floors. It's used when utilities, HVAC ducts, or other systems must route through concrete, and when engineers need core samples to test concrete strength and quality.
Common questions about concrete coring in San Antonio
We use ground-penetrating radar (GPR) or electromagnetic scanning to locate rebar, conduit, and cables before drilling. This allows us to adjust hole placement and drilling technique to avoid damage.
Yes. Diamond-core rigs can be positioned to drill vertically, horizontally, or at custom angles. Overhead drilling requires proper safety rigging and operator certification, which we provide.
Permitting requirements depend on the project scope and location within San Antonio. We advise contacting the City's Development Services Department early in planning. We provide documentation to support your permit application.
We core holes from 1 inch to 12+ inches in diameter and up to 18 inches deep in standard applications. Deeper or larger holes require specialized rigs. Contact us with your specifications.
Water is used as a coolant and dust suppressant during drilling. We manage water runoff and clean the area after work is complete. Dust containment can be arranged for sensitive environments.
Yes. We extract intact cores per ASTM standards, label them according to your engineer's requirements, and prepare documentation for lab analysis or structural assessment.
