CIPP Rehabilitation
Custom engineered CIPP liners are installed through manholes or open culverts, creating a structural, tight fit, resin-based liner inside 6- to 108-inch diameter host pipes.

Trenchless portfolio of services that helps ensure vital subsurface infrastructure repairs are completed efficiently and with precision
National Underground Group provides municipalities, engineers and utility companies with the trenchless pipe repair expertise and technologies they need to eliminate the costs and disruptions associated with pipe repair and replacement projects, involving excavation.
Our cured-in-place-pipe (CIPP) rehabilitation enables trenchless repairs to be made to sewer infrastructure and storm drains using CIPP liners. Installed through a manhole or an open culvert, this product creates a structural, tight fit, seamless liner inside the entire run of the existing host pipe. Inspection and testing are performed to make sure the repaired pipe performs as designed and is capable of assuming all functions of the host pipe. The pipe-in-pipe solution is solely sustainable, and the “new” pipe bears all external loads without support from the host pipe, providing a complete, structural solution.
National Underground Group’s lateral connection seal services provide the expertise and technologies needed to ensure safe and efficient repairs are made to damaged or degraded lateral-to-main sewer line connections, while eliminating the disruptions and potential risks associated with traditional excavation methods.
Besides rehabilitation efficiency, we understand that our repairs must completely restore the integrity of lateral-to-main connections to prevent any infiltration or exfiltration of water, which can lead to a host of problems, including groundwater contamination, sewer backups, leaks and pipe failures.
Another offering under our trenchless rehabilitation services is our rehabilitation support. This service enables us to maximize repair efficiency of subsurface infrastructure by eliminating the need to replace or reline entire pipelines or excavate the surface area under which they run. Beyond providing the latest infrastructure rehabilitation methods and technologies, our experienced professionals have the expertise to provide complete, customer-based solutions in-house and effectively and efficiently manage rehabilitation operations, helping to ensure projects meet design and budget requirements.
Subsurface infrastructure rehabilitation stakeholders seeking a dependable and all-inclusive provider will find one with our turnkey solutions services. Our broad knowledge of utility rehabilitation and extensive range of pipe repair technologies make us the perfect partner for those seeking a provider with comprehensive rehabilitation capabilities. We understand the importance of tailoring our services to meet each client’s unique goals and budgetary requirements without unnecessary delays or workovers. Our integrated planning and communication approach creates a collaborative environment, allowing us to thoroughly assess projects, provide informed recommendations, and ultimately deliver the desired results safely and efficiently.
Lateral Connection Seal

Whom We Serve
Municipalities and Government Agencies
When it comes to projects for municipalities and government agencies, on-time delivery is key. National Underground Group’s data-driven approach to pipe and infrastructure inspection enables construction stakeholders to better plan their subsurface repair and installation projects. Accurate and available inspection information enables construction crews to work safely and efficiently, adhere to regulatory standards, and guard against damage to existing infrastructure, project delays and budget overruns. We also offer preventive and proactive solutions that help keep subsurface pipes in optimal condition.
Engineering Firms
National Underground Group’s engineering industry pipeline services include a range of accurate and efficient evaluations. We use advanced closed-circuit television (CCTV) technology to produce Pipeline Assessment Certification Program (PACP) exchange databases, and conduct thorough CCTV lateral launch inspections and engineering CCTV mainline inspections to provide accurate, reliable data that facilitates optimal timing and methods for repair and maintenance. From pipe locating and mapping, cleaning and assessment to trenchless rehabilitation and cross bore inspection, we provide solutions engineers need to satisfy their clients.
Contractors
Contractors who work on subsurface wastewater infrastructure installation or repair projects find the most reliable support from a subsurface pipe specialist with a range of capabilities. National Underground Group provides all the services for an infrastructure project and tailors solutions to the specific requirements of our contractor clients. We know the safest, most efficient and cost-effective methods for performing subsurface pipe inspections, maintenance, installation and repair and use the most advanced technologies to ensure jobs are completed on time and on budget.
