Dam, Lock & Waterway Hydrodemolition
Contractor test

Aggregate Technologies is a nationally deployed specialty hydrodemolition and concrete removal contractor headquartered in Houston, Texas, with additional offices in Baton Rouge, Louisiana and a satellite office in Orlando, Florida. Founded in 1997 and in business for nearly 30 years, the company has executed dam, lock, and waterway concrete scopes for general contractors, engineers of record, federal agencies, USACE, and private dam owners across the continental United States. Aggregate Technologies holds current prequalification through ISNetworld, Avetta, and HASC, carries a 0.74 EMR safety rating, and is a federally registered small business eligible for USACE set-aside procurement. When your prime contract includes hydrodemolition, selective demolition, or concrete removal on a dam, lock, or federally regulated waterway structure, Aggregate Technologies is the prequalified specialty sub that shows up ready to produce, not to plan.

Why Concrete Scopes Fail on Dam, Lock, and Waterway Projects

As the prime contractor, a specialty sub's failures are yours to own. Here's what makes selecting the wrong concrete sub on a dam or lock project so costly, and why general contractors across the country keep bringing Aggregate Technologies back to their waterway scopes.

Zero tolerance for vibration damage

Dam and waterway specs call for hydrodemolition for a reason. Mechanical or explosive methods risk adjacent structural concrete and rebar. A specialty sub that doesn't own and operate the right equipment triggers a variance request chain reaction you don't have time for.

Tidal and navigation access windows

Lock schedules, Army Corps navigation restrictions, and tidal windows compress your working time. A concrete sub who isn't prepped and prequalified before mobilization day burns the window before anything is produced. That lost schedule time is gone and it costs you.

Federal safety and compliance liability

On Army Corps and federally regulated waterway structures, your specialty sub's EMR and ISNetworld status become your problem the moment they're on site. An expired certification doesn't just delay the sub. It delays your entire crew and puts a mark on your prime contract relationship.

Dam, Lock & Waterway Concrete Services

Aggregate Technologies has executed the most technically demanding dam, lock, and waterway concrete scopes in the country. Headquartered in Houston with operations across the Gulf Coast and beyond, we mobilize nationally for projects where the scope is large enough to require a specialty sub who has already solved the problem. Here's what we deliver where others can't.

Dam hydrodemolition

High-pressure water demolition on dam faces, spillways, and gate structures. Preserves rebar integrity, eliminates spark risk, and creates ideal bonding surfaces for overlays. The method of choice on dam rehabilitation specs nationwide.

Concrete scarification & surface prep

Dam faces, spillways, and gate structures prepared to meet profile specifications for overlay adhesion. Aggregate Technologies hits those specs consistently across large surface areas and in confined access conditions

Selective & Robotic Demolition

In confined lock chambers and gate bays, our robotic demolition equipment accesses spaces human operators cannot reach. Zero vibration and zero compromise on adjacent structural elements.

Wire Sawing & Core Drilling

Cutting through mass concrete sections, removing gate sill concrete, and creating penetrations through thick structural walls. Aggregate Technologies has executed all of it on active dam, lock, and waterway projects.

Underwater Demolition Support

Aggregate Technologies has operated below the waterline on dam, lock, and waterway structures. From dam toe removal to submerged pile cutting, our below-waterline experience is documented and proven on active projects.

Refractory & legacy material
removal

Older dam, lock, and waterway structures often contain deteriorated legacy materials. AggregateTechnologies removes what the next contractor can't, safely and completely, and documents it to your spec.

What GCs Get When Aggregate Technologies Is on the Scope

  1. Pre-mobilization scope coordination


    Once your contract is awarded and Aggregate Technologies is confirmed as the concrete specialty sub, we review your scope drawings, access constraints, tidal and navigation scheduling requirements, and equipment positioning with your project team before mobilization day. There are no surprises on day one. We show up to produce, not to plan.

  2. Prequalification already handled


    ISNetworld, Avetta, and HASC compliance is current before you call us, whether your project is on the Gulf Coast or anywhere else in the continental United States. We don't make your project team wait on safety documentation. It's ready to go. You verify it and we mobilize. Federal facility background checks are standard for our crews.

  3. Crew mobilization & field execution


    Our field crews are trained, background-checked, and ready for federal and regulated facility access. We bring the equipment, the operators, and the daily accountability to your schedule and we execute to spec without requiring your superintendent to manage us through the work.

  4. Closeout that is clean and on time


    We document the work to your closeout requirements, coordinate waste and water management, and demobilize completely on your timeline. We don't leave loose ends that delay the next trade behind us. When Aggregate Technologies is done, the scope is done.

What Sets Aggregate Technologies Apart on Dam, Lock, and Waterway Work

▸ Federal facility ready before you ask:

Pre-qualified through ISNetworld, Avetta, and HASC. Crews clear background checks and federal access protocols without delay. Our compliance documentation is current and available before your procurement team requests it.

▸ Hydrodemolition specialists, not generalists:

Aggregate Technologies owns and operates its hydrodemolition equipment. We don't rent it and figure it out on your project. Our operators are trained and certified through Aqujet, the hydrodemolition equipment manufacturer, and have run this technology on dam, lock, and waterway structures nationwide.

▸ Zero rebar damage & vibration record on structural rehab:

On projects where rebar preservation is the entire point, dam and lock rehabilitation specifically, our hydrodemolition record speaks for itself. We have never compromised a rebar mat on a structural rehabilitation project.

▸ Waterway infrastructure experience, nationwide:

We know the waterways, the regulatory bodies, and the contractors who manage dam and lock infrastructure. From Gulf Coast waterway systems to federal waterway structures across the country, we have been on these jobs and we know what they require.

▸ Direct, accountable leadership:

One call reaches our leadership on a dam project. There are no layers of management between you and the people running the job. Your dedicated project manager is reachable by email, phone, or text at every phase of the work.

▸ Federally registered small business:

Aggregate Technologies is eligible for small business setaside procurement on USACE and federally regulated waterway projects. SAM.gov active. CAGE Code 35VP7. NAICS 238990.

"On dam and lock rehabilitation work, there's no room to learn on the job. You want a contractor who has already solved the problem you're facing and can prove it before they touch your structure."

Common Questions from General Contractors

▸What is hydrodemolition and why is it required on dam, lock, and waterway projects?

Hydrodemolition uses ultra-high-pressure water jets to remove deteriorated concrete without vibration, sparks, or damage to embedded rebar. On dam, lock, and waterway structures, it is often specified by engineers of record, USACE, and other regulatory bodies because mechanical or explosive demolition risks damaging adjacent structural concrete and rebar mats. That kind of damage can compromise the entire rehabilitation scope. Aggregate Technologies has operated robotic hydrodemolition equipment on dam, lock, and waterway structures across the continental United States for over 10 years, and has been in the specialty concrete business for nearly 30.
