A culvert is a pipe or enclosed structure that carries stormwater under a road, driveway, or embankment, connecting drainage on one side to the other. When a culvert backs up with sediment and debris, water cannot pass through the pipe and instead flows over or around the road, flooding the area upstream and eroding the embankment and pavement above.
Flotech Environmental provides culvert cleaning, desilting, and trenchless culvert repair for municipalities, contractors, and property managers across Florida. Our fleet of over 30 combination jet vac trucks delivers up to 4,000 PSI of water pressure and 5,000 CFM of vacuum, removing sediment, debris, and vegetation from culverts and storm pipes from 6 inches through 96 inches in diameter. Routine culvert cleaning and desilting helps restore stormwater system capacity to originally permitted design conditions, which is required under Florida’s Environmental Resource Permitting program (Rule 62-330, F.A.C.).
Operation and maintenance are conditions of the permit, and because HOAs and property managers fall outside the MS4 framework, the obligation lands on them directly, including a written O&M plan and periodic inspections confirming the system “continues to function as designed and permitted” (DEP ERP Applicant’s Handbook, 2024). Flotech handles this as a single workflow. Our CCTV inspection crews assess pipe condition from the inside, and when structural defects are identified, we perform trenchless repair using CIPP or sectional point repairs (ASTM F1216/F2599) and chemical grouting, restoring the pipe from the inside without closing the road.
Here are some of the most common questions about our services, response times, and how we support infrastructure projects across Florida.
For commercial developments and industrial sites, the property owner or the homeowners’ association (HOA) is generally responsible for the upkeep of all internal drainage structures. This includes the culverts under site entrances and those connecting on-site retention ponds. We partner with commercial property managers to perform professional jet-vac cleaning and repairs.
Compared to cohesive soils, Florida’s sandy material is prone to rapid erosion, potentially undermining culvert support. You should look for depressions or "soft spots" in the asphalt or landscaping directly above the pipe, sediment being expelled from the culvert outlet during dry weather, or concrete mitered ends that appear to be sinking or pulling away from the roadway. If you notice a whirlpool forming over the pipe during a rain event, it often indicates a structural breach that is sucking soil into the system.
Jet vac cleaning services are commonly used by municipalities, utility departments, HOAs, commercial property managers, industrial facilities, contractors, and engineering firms. These services support the maintenance of sewer systems, stormwater networks, catch basins, lift stations, manholes, and other underground infrastructure assets.
Our high-pressure water jetting and jet-vac desilting services remove heavy sediment and restore flow in box culverts and outfalls. We use powerful vacuum technology to safely extract sand, rocks, and organic debris that collect in these structures, returning them to their full design capacity and preventing upstream flooding.
We use NASSCO-certified technicians and robotic cameras to perform detailed internal inspections of drainage structures. This process allows us to identify cracks, joint separations, and root intrusion, providing the data needed to determine if culvert repairs or trenchless rehabilitation are necessary to maintain structural integrity.
We offer minimally invasive repair solutions to seal leaks and stabilize the soil surrounding damaged culverts. By injecting specialized chemical grouts and installing sectional liners, we stop infiltration and fill external voids without the need for disruptive excavation or road closures.
When unexpected storm events or major debris cause immediate drainage failures, we provide rapid response services to clear the obstruction. Our crews are available to perform the urgent culvert cleaning Florida property managers need to mitigate rising water and protect infrastructure from further damage.
Culverts play a critical role in stormwater management, but without routine maintenance, they can become blocked, damaged, or unstable. Proper care helps prevent failures and extend system life.
Culvert repairs restore flow to the original design capacity to prevent flooding and help prevent costly roadway reconstructions and emergency repairs through early intervention. They enhance public safety by eliminating sinkhole risks and washouts while protecting local water quality by removing accumulated pollutants, trash, and sediment. Using trenchless culvert repairs also minimizes community disruption by avoiding open-cut excavation.
Our work is measured not just by what we complete, but by the trust we build along the way. Here’s what clients across Florida have to say about working with Flotech.
Culverts carry stormwater under the roads, driveways, and entrances a community depends on, and in most Florida communities they are private infrastructure owned by the association. Florida averages 40 to 60 inches of rainfall a year, and a sediment-loaded culvert performs like an undersized one. FEMA identifies deferred maintenance as a reason stormwater structures fail during severe storms, and culvert failures are the expensive kind: washouts, pavement collapse, and a blocked entrance when residents and emergency vehicles need it open. Routine culvert cleaning and desilting prevents that failure and keeps the system at the capacity it was permitted with, and for an association, documented maintenance is also proof the system is being kept up as the permit requires.
From routine maintenance to emergency blockage removal, Flotech provides the cleaning, inspection, and repair services needed to keep your culverts operating at full capacity. Contact us today to get started.
