Post-Tension Slab Cutting & Coring

Almost all modern high-rises, commercial buildings, and parking garages in Miami and Fort Lauderdale are constructed using post-tension (PT) cable slabs. Accidentally severing a high-tension steel tendon during a renovation is a catastrophic, multi-million-dollar mistake that threatens the entire structural envelope. We provide precision slab sawing and core drilling engineered specifically for PT structures, working hand-in-hand with General Contractors to ensure every cut is executed safely and flawlessly.

Pre-Cut Safety GPR Concrete Scanning

Before a blade ever touches the concrete, we mitigate risk. We highly recommend and utilize Ground Penetrating Radar (GPR) scanning to locate and physically mark the exact depth and trajectory of the post-tension tendons and rebar within the slab. This data allows us to map out safe cutting zones and avoid structural disasters.

Structural Openings Precision Slab Sawing

When retrofitting a commercial space to include a new elevator shaft, internal stairwell, or large HVAC ductwork, you need massive geometric openings cut through the floor. Our track-mounted wall saws and heavy-duty slab saws slice cleanly through the concrete between the tension cables, leaving sheer, smooth faces ready for the next phase of construction.

Commercial MEP Specialized Core Drilling

Plumbers and electricians face major hurdles when routing utilities through PT slabs. Our high-torque Weka and Husqvarna core drills allow us to safely bore perfectly cylindrical holes for PVC, conduit, and floor drains. We adjust our RPMs and monitor feed pressure meticulously to ensure we are only cutting the concrete and never forcing through a hidden tendon.

Extreme Liability Protection

Cutting a PT cable can cause the tendon to violently rip through the concrete, causing severe injury and structural failure. We carry comprehensive Workers' Compensation and General Liability Insurance specifically suited for high-risk commercial concrete modifications.

Hydraulic Control

We utilize precision hydraulic equipment (ICS Chainsaws and Wolverine Hand Saws) that gives our operators ultimate feedback and control. Unlike erratic jackhammers, our diamond blades slice exactly where we tell them to, down to the millimeter.

Zero Dust & Fumes

Working inside occupied high-rises or poorly ventilated parking garages demands strict environmental control. Our hydraulic power packs emit zero exhaust, and our wet-cutting methods instantly trap and neutralize hazardous silica dust.

Post-Tension Slab FAQs

What exactly is a post-tension (PT) slab?

A post-tension slab is a concrete floor that is reinforced with high-strength steel cables (tendons) stretched tightly inside protective sheathing. This tension compresses the concrete, allowing it to be thinner and span larger distances without structural support columns. They are standard in modern South Florida high-rises and parking garages.

Why is cutting a post-tension slab dangerous?

Because the steel cables inside the slab are held under immense tension (often over 25,000 lbs of force), cutting one by accident causes it to snap violently. The cable can burst out of the concrete, causing catastrophic injuries, massive property damage, and instantly compromising the load-bearing integrity of the building.

How do you prevent cutting the tension cables?

We mandate that a thorough Ground Penetrating Radar (GPR) scan is completed before cutting begins. GPR technology maps the interior of the slab, identifying the exact depth and layout of the tendons. We physically mark the concrete, creating safe, "green-lit" zones for our diamond blades to pass through.

Can you core drill for plumbing in a PT slab?

Yes. We routinely core drill through PT slabs for commercial MEP contractors laying plumbing lines, electrical conduit, and HVAC drains. By utilizing GPR scanning first, we locate the safe gaps between the tendons and drill precise holes without hitting the steel.

Do you operate in occupied buildings?

Absolutely. We specialize in interior renovations for active high-rises, condos, and retail centers. Our hydraulic equipment produces zero dangerous exhaust fumes, and our strict wet-cutting methods ensure zero airborne silica dust enters the building's ventilation system.

What if structural drawings say it's safe to cut?

We never rely solely on "as-built" structural drawings. Over decades of experience in Miami construction, we know that original blueprints are rarely 100% accurate to how the cables shifted during the actual concrete pour. A live GPR scan is the only way to guarantee a safe cut.
