Services
Trenchless Pipe Repair
Our trenchless pipe repair utilizes CIPP technology to rehabilitate damaged sewer lines without excavation. This method creates a durable, jointless pipe within existing infrastructure, lasting up to 50 years. Ideal for repairing clay, cast iron, or asbestos pipes, this minimally invasive solution reduces costs by 30-50% compared to traditional replacement while maintaining structural integrity.
Backflow Prevention
We provide certified backflow testing, installation, and maintenance services to protect public water supplies. Our specialists comply with Louisiana Administrative Code Title 51 regulations, offering annual testing, device repairs, and cross-connection surveys. We coordinate testing during off-hours to minimize business disruption and submit results directly to water purveyors for compliance documentation.
Mainline Inspection
Our mainline camera inspections use steerable 6-48 inch diameter equipment to identify cracks, root intrusions, and blockages. Each inspection includes a detailed video report with repair recommendations. We offer CIPP rehabilitation for identified defects, eliminating the need for traditional excavation while restoring pipe functionality to meet industry standards.
Facility Maintenance
We provide comprehensive facility maintenance covering industrial/commercial plumbing systems. Services include drain jetting, fixture repairs, gas line maintenance, and water heater servicing. Our preventive maintenance programs reduce emergency failures by 60% through regular inspections and proactive repairs, ensuring continuous operation for businesses.
Sewer Rehabilitation
Our Site Sewer Rehabilitation Program includes diagnostic assessments of entire wastewater systems. We inspect fixtures, piping, lift stations, and treatment plants to identify critical deficiencies. Using trenchless technology and traditional methods, we implement repairs that extend system lifespan while maintaining compliance with environmental regulations and minimizing site disruption.
