Commercial Hydrodemolition Contractors

“Unmatched Excellence in Long-Lasting Concrete Removal and Repairs”

Introducing HydroDemolition

Stone Restoration HydroDemolition is our state-of-the-art solution for concrete, coating, and sealant removal. This advanced method outperforms traditional demolition techniques, offering superior results and enhanced safety. Hydrodemolition employs high-pressure water jets delivered through a computer-controlled robot to precisely eliminate unwanted materials without causing micro-cracking in the remaining concrete, ensuring the structural integrity of your surfaces.

This environmentally friendly process minimizes waste and disruption, making it a cost-effective and time-efficient choice for your commercial property. Stone Restoration HydroDemolition surpasses traditional jackhammering in efficiency, preserving your concrete substrates and reducing downtime. Embrace the future of concrete restoration with our innovative HydroDemolition service.

Traditional Concrete Removal Damages What You Are Trying to Save

Jackhammering and pneumatic chipping are blunt methods. They remove deteriorated concrete, but the impact energy travels into the surrounding material. The result is micro-cracking in substrate that looks sound but has compromised bond strength as well as rebar damage from mechanical impact. . New overlays applied to micro-cracked substrate bond poorly and delaminate ahead of schedule. The failing overlay gets replaced. The cycle repeats.

On parking decks, bridge decks, and industrial slabs, delaminated overlays are frequently caused by inadequate substrate preparation rather than material or product failure. Selecting the right removal method from the start eliminates that failure mode and the cost that comes with it.

SRA’s Hydrodemolition Capabilities

Stone Restoration of America owns and operates the robotic hydrodemolition equipment and high-pressure pump rig. The crews are trained in hydrodemolition operations. This is not subcontracted work.

That end-to-end capability matters on real projects. The same contractor that removes the concrete can complete the replacement, repair, and coating or sealant application. One contractor, one schedule, no handoff between trades to manage.

We maintain a Conjet 327 Robot as well as a Hammelmann 307 Pump capable of up to 20,000 PSI water pressure.

Where is HydroDemolition Used?

Parking Structures

Deteriorated concrete on parking deck surfaces, ramps, and structural members is selectively removed without damaging the reinforcing steel or the adjacent sound concrete. Hydrodemolition is well-suited to partial-depth repairs and full-depth deck rehabilitation on occupied parking structures.

Industrial Floors and Slabs

Failed coatings, delaminated overlays, and contaminated concrete surfaces in industrial facilities are removed without the vibration that would damage adjacent equipment, expansion joints, or connected slabs. Downtime is reduced compared to mechanical removal on large surface areas.

Tunnels and Below-Grade Structures

Equipment configurations compatible with confined-space conditions allow hydrodemolition in tunnels, below-grade parking structures, and other applications where traditional equipment access is restricted.

Bridge Decks

NCDOT and SCDOT departments accept hydrodemolition as a standard method for bridge deck rehabilitation. Robotic water jetting removes delaminated and chloride-contaminated concrete to precise depths with minimal disturbance to structural integrity and the surrounding material.

Building Facades and Structural Elements

Paint and coating removal as well as Deteriorated concrete on columns, beams, spandrels, and facade panels is removed to expose corroded reinforcing steel for treatment and re-encasement. Hydrodemolition is precise enough for vertical and overhead applications on occupied commercial structures.

HydroDemolition Frequently Asked Questions?

What is Hydrodemolition?
Hydrodemolition uses high-pressure water jets with up to 40,000 PSI, delivered through a computer-controlled robotic system, to remove deteriorated concrete, coatings, and sealants. The water jet removes compromised material while leaving sound concrete intact. Because water does not transmit impact energy into the substrate the way a mechanical tool does, there is no micro-cracking in the remaining material.

The surface profile left by hydrodemolition is rough, aggregate-exposed, and chemically clean by removing chlorides, oils, and laitance that would interfere with overlay adhesion, which mechanical prep can’t fully achieve. It bonds to overlays, repair mortars, and new concrete better than surfaces prepared by mechanical means. Better substrate preparation produces repairs and overlays that last.

Why Does Robotic Hydrodemolition Outperform Traditional Methods?
No micro-cracking. The water jet does not transmit impact energy into the substrate. Mechanical demolition methods do. The difference shows up in overlay bond performance and how long the repair lasts.

Superior surface profile. Hydrodemolition leaves a roughened, aggregate-exposed surface that provides better mechanical bond for overlays than grinding, milling, or chipping.

Selective removal. Computer-controlled depth control removes only what needs to go. Sound material stays in place. On partial-depth repairs, that precision reduces the volume of concrete replaced and shortens project timelines.

Reduced dust and vibration hazard. There is no silica dust generation from hydrodemolition, which addresses an OSHA-regulated exposure risk in concrete demolition work. There is also no vibration transferred to adjacent structures or occupied areas.

Water recapture, containment and treatment of PH levels can be included as part of the Hydrodemolition process.

What is the difference between hydrodemolition and jackhammering?
Jackhammering transmits impact energy into the surrounding concrete, causing micro-cracking in material that appears intact. Hydrodemolition uses high-pressure water to remove material without mechanical impact. The remaining concrete is undamaged, and the surface profile is better suited to overlay bonding. The practical difference shows up in how long the repair lasts
What factors affect hydrodemolition cost?
Project cost depends on the area to be treated, the depth of removal, the concrete’s compressive strength and condition, how accessible the work surface is, and schedule requirements. Contact SRA for a project-specific quote.
What surfaces can hydrodemolition be used on?
Hydrodemolition works on horizontal surfaces such as parking decks, bridge decks, and slabs, vertical surfaces including columns, walls, and spandrels, and overhead applications. Both partial-depth and full-depth removal are possible depending on project requirements.
