For Dam, Lock & Waterway Hydrodemolition
You Need the Concrete Surgeons

When your prime contract includes hydrodemolition, selective demolition, or concrete removal on a dam, lock, or federally regulated waterway structure — you need a specialty sub that plans ahead, shows up prepared, and keeps the job moving.

Aggregate Technologies is that sub. Headquartered in Houston, Texas with offices in Baton Rouge and Orlando, our concrete removal work takes us across the entire country. Founded in 1997, we've spent nearly 30 years executing dam, lock, and waterway scopes for general contractors, engineers of record, federal agencies, USACE, and private dam owners. We partner with contractors, engineers, and owners from the start — identifying risks and solving problems before they hit the field.

We come prequalified — ISNetworld, Avetta, and HASC current, a 0.74 EMR safety rating, and federally registered as a small business eligible for USACE set-aside procurement.

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

THE PROBLEM

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.

WITH US

We take that off your plate.

We own one of the largest hydrodemolition fleets in America. We don't rent. We don't improvise. We are certified trainers for our own equipment and recognized leaders in the industry — backed by a full range of concrete cutting and removal methods when the scope demands it.

Tidal and navigation access windows

THE PROBLEM
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.
WITH US

That's not a problem you'll have with us.

We plan around facility timing before we ever mobilize. And our extended reach capabilities — not available on the open market — mean less equipment movement, fewer setups, and more production inside every window.

Federal Safety & Compliance Liability

THE PROBLEM
On Army Corps and waterway structures — federal or otherwise — 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.
WITH US

With us, that's already handled.

We arrive with ISNetworld, Avetta, and HASC current and on file, a 0.74 EMR safety rating, and we are fully insured and bondable upon request. You're not chasing paperwork. We are.

Water capture and treatment is part of our scope. Our mobile treatment centers process water to the required pH levels — ready to be reused or safely released back into the environment.

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.

▸ Rebar, Substrate & Vibration Control on Structural Rehab

On dam and lock rehabilitation, rebar preservation isn't a best practice — it's the whole point. Chipping hammers create vibrations that cause microcracks in surrounding substrate. Hydrodemolition doesn't. We take that distinction seriously on every project.

▸ Waterway infrastructure experience, nationwide:

Every dam and lock project is unique — different waterways, different regulatory bodies, different stakeholders. We come ready to learn what your project requires and partner with you to make sure every party, from the contractor to the federal agency or private owner, gets what they need.

▸ 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.

▸ What Happens to the Water?

Water capture and treatment is part of our scope. Our mobile treatment centers process water to the required pH levels — ready to be reused or safely released back into the environment.

▸ Fully Insured and Bondable

We carry full insurance and are bondable upon request — so you're protected from day one and have one less thing to manage on your prime contract.

"On dam and lock rehabilitation, you want a subcontractor who has done the work before and comes prepared — the more that's solved in advance, the better the outcome on 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.
