Core Drilling Services | Clean Openings for Concrete Projects

What Core Drilling Does

Core drilling supports structural modifications, utility penetrations, and large-scale infrastructure work on active commercial and industrial job sites. Our crews utilize job-specific drilling systems to deliver precise, controlled results while maintaining safety, communication, and production throughout the project.

We provide both standard and custom core diameters up to 48 inches. For oversized or engineered penetrations, we mobilize specialized rigs and custom-fabricated core bits to meet exact specifications. In addition to conventional drilling, we have developed advanced solutions for specialized environments, including a pneumatic underwater rock drilling systems successfully deployed by certified divers on U.S. Army Corps of Engineers project sites.

Where Core Drilling Is Used

Core drilling is used across a wide range of construction and infrastructure applications, including:

Utility penetrations for plumbing, electrical, and HVAC systems
Structural modifications in walls, floors, and foundations
Bridge decks, roadways, and heavy civil projects
Industrial facilities, production plants, and clean environments
Geotechnical drilling and deep foundation work
Underwater and marine construction

For larger openings beyond standard core sizes, core drilling can be used in conjunction with wire sawing. Using core drills, we establish access points that allow wire sawing to complete controlled cuts for oversized or nonstandard openings.

How We Perform the Work

Every project begins with evaluation of drilling and site conditions. Our technicians select the proper equipment to maintain clean, controlled drilling. We routinely adapt our approach to meet project demands, including:

Custom rig configurations for oversized and engineered drilling
Precision drilling through reinforced concrete and structural steel
Deep drilling capabilities reaching 74 feet, with capacity up to approximately 140 feet
Integration of robotic drilling systems for confined or high-risk environments
Specialized setups for underwater and production-rate rock drilling

Our crews coordinate closely with our contractors and maintain clear communication from start to finish. This ensures work stays aligned with project schedules and supports maintaining deadlines on active job sites.

You get controlled execution, adaptable solutions, and dependable results that keep your project on track.

Deep and Oversized Core Drilling Capabilities

For projects that go beyond standard drilling limits, ACS provides deep core drilling capabilities reaching up to 140 feet, supporting geotechnical work, deep utility installations, and specialized structural applications.

When openings exceed standard core diameters, we use core drilling in combination with wire sawing to create oversized penetrations. Starter core holes are used to route wire saw systems, allowing us to cut larger-than-standard openings with precision. This method is especially effective in thick or heavily reinforced concrete where traditional drilling alone is not practical, delivering clean edges and controlled removal while keeping your project on schedule.

Sawing Services

Core Drilling

From standard utility penetrations to oversized and deep drilling applications, ACS provides precision core drilling for commercial, industrial, and heavy civil construction. Our experienced technicians utilize specialized equipment to deliver accurate results while maintaining production and project schedules.
Whether your project requires a single core or hundreds of penetrations, our capabilities include oversized drilling, deep core drilling, robotic applications, and challenging access conditions where experience makes the difference.

Flat Sawing

ACS performs flat sawing for everything from roadway construction and bridge rehabilitation to interior renovations and structural modifications. Our fleet includes high-horsepower roadway saws and fume-free electric equipment for occupied buildings and sensitive environments.
With experienced operators, specialized equipment, and the ability to scale crews for demanding schedules, we deliver clean, accurate cuts while helping keep your project moving.

Curb Cutting

Curb cutting provides a fast, efficient alternative to traditional curb removal by creating clean horizontal cuts directly at roadway grade. This process minimizes demolition, reduces restoration costs, and helps keep roadway projects moving.

Beyond driveway access, our curb cutting equipment is also used for bridge railings, retaining walls, barriers, and other applications requiring controlled, linear concrete removal.

Robotics

Remote-operated robotic demolition allows ACS to perform high-production concrete removal safely in confined spaces, elevated work areas, and occupied facilities. Zero-emission equipment makes these systems ideal for interior demolition and sensitive environments.

With multiple attachments available, our robotic fleet can perform demolition, trenching, scarifying, excavation, and specialized structural removals while reducing worker exposure and increasing productivity.

Wall Sawing

Our wall sawing crews provide precise structural openings for doors, windows, mechanical penetrations, and engineered removals. Using remote-operated equipment, we safely perform work in commercial buildings, industrial facilities, bridges, and infrastructure projects.
From routine openings to complex crane-assisted removals, ACS has the equipment and experience to complete challenging wall sawing projects safely and efficiently.

Wire Sawing

When conventional cutting methods reach their limits, wire sawing provides the solution. ACS performs wire sawing for massive concrete structures, heavily reinforced sections, underwater applications, and areas with limited access.
By combining wire sawing with deep core drilling, we can complete oversized removals, thick structural cuts, and unique demolition projects that require precision and control.

Ground Penetrating Radar (GPR)

Before cutting or drilling begins, knowing what’s inside the concrete is critical. ACS uses advanced Ground Penetrating Radar (GPR) technology to locate reinforcing steel, post-tension cables, conduits, and embedded utilities.

Our scanning services help reduce risk, improve safety, and provide contractors with the confidence to proceed without damaging critical structural or utility components.

Concrete Grinding and Scarifying

Proper surface preparation is essential for a successful project. ACS provides concrete grinding and scarifying services for floor preparation, slope corrections, surface texturing, and controlled material removal.

From decorative flooring preparation to large surface removals, our equipment delivers accurate results while HEPA dust collection systems help maintain clean working environments.

Patch Back

ACS provides complete patch back solutions to help move your project from removal to restoration. From plumbing trenches and machine pads to structural repairs and specialized concrete placements, we coordinate the right crews to complete the work to specification.

For larger placements, we partner with trusted concrete contractors who meet the same standards of quality and professionalism as our customers expect from ACS.

Slurry Processing

Keeping your project clean is just as important as completing the work itself. Our Totally Clean Service provides slurry containment, processing, and removal for projects where cleanliness and contamination control are essential.

Designed for hospitals, clean rooms, office buildings, kitchens, and active facilities, our specialized methods help protect surrounding areas while allowing construction to continue safely.
