Customers in this region of the United States can expect to receive expertise in both the design and execution of the services below.

Robotic Services

Drain Pipe Inspection

We specialize in all aspects of pipeline inspection leveraging the use of top of the line pipe camera inspection and video inspection equipment to conduct proper assessments. As a underground inspection and rehabilitation services provider, we are fully compliant and certified with best practices including: Manhole Assessment Certification Program (MACP), Lateral Assessment Certification Program (LACP) and Pipeline Assessment Certification Program (PACP).

We also recognize that certain industries and building structures command a unique approach when assessing their infrastructure and overall pipe system health. This understanding enables us to serve the following industries and building structure types:

  • Hospitals
  • Food Processing Plants
  • Universities & Schools
  • High Rise Buildings

CCTV Inspection

Our Closed Circuit Television (CCTV) inspection services consist of either a push camera or a remotely operated camera mounted on a self-propelled robotic crawler that is connected to a video monitor at the surface. Consistent with our commitment to trenchless rehabilitation, our CCTV services allows for inspection of the inside of pipes without needing to dig trenchless or excavate through the floor on a customer’s property to expose the system.

Preventive inspections are encouraged to be conducted on an annual basis so as to identify clogs before they become expensive problems while also assessing the condition of the pipeline materials themselves.

In sum, our CCTV Inspections allow us to determine:

  • Structural condition
  • Location of structural defects
  • Evidence of inflow & infiltration
  • Size and material of construction
  • Location of service laterals
  • Location of obstructions, such as grease, roots, debris and cross bores


Many municipalities during the planning and development stages of building integrate branches and molded bodies into their sewer networks to prepare for future expansion. However, many times these additional branches end up not being used in the future. The result is a need for sealing these blind connections.

Schwalm Sewer Plug System

Utilizing our Schwalm robots, we have the ability to tightly seal blind connections permanently by utilizing the Schwalm Sewer Plug System’s compression plugs. The plugs are available in four (4) different sizes and are suitable for lateral pipe sizes of 4” – 8” and main line sizes of 8” – 24”.

Robotic Cutting

A critical part of sewer rehabilitation is the reconnection of the laterals once a sewer pipe has been relined. With our Schwalm Robotic and Picote lateral cutters we can reopen connections and get service back up and running in the least amount of time possible.

In addition to lateral reinstatements, we also offer additional cutting services such as grinding out mortar, root removal and concrete removal via high-pressure water or air.

Pipe Sizes Serviced:

  • 4” – 24”

Cutting Services:

  • Lateral Reinstatement
  • Mortar Removal
  • Concrete Removal
  • Root Removal
  • Failed Liner Removal
  • Protruding Pipe Removal
  • Failed Gaskets Removal

Robotic Cleaning

Hydro jetting is an efficient and economical method of cleaning with high-pressure streams of water to remove build up and debris in drain lines, sewer lines, outside drains and storm drains. Using high-pressure water and flexible hosing, we can scrub drains, pipes, flush out residue and dirt, remove tree roots and break up soft clogs such as grease, hair or sediment.

In scenarios where hydro jetting satisfies the cleaning portion of a project but leaves particulate deposits at branches or recesses, we offer robotic cleaning for precise and accurate flushing. Our Schwalm Water Cutter allows for removal of particle deposits where jet cleaning cannot reach, helps to cut through large roots and concrete and can also be used for descaling cast iron pipes.

Pipe Sizes:

  • 4” – 24” diameter pipes with the Hydro Jetter
  • 8” – 24” diameter pipes with the Schwalm Robot

Lining Services

Main Lining

The (CIPP) cured in place pipe rehabilitation process continues to be an economical and efficient alternative to traditional pipe system replacement. Specific to Main Lining, we offer continuous manhole to manhole lining as a means of rehabilitating safely and cost-effectively.

All main lining services are performed following a careful inspection of the pipes to evaluate whether or not there is a need to remove corrosion or clogs prior to lining. In instances where cleaning is necessary, we leverage our hydro jetting equipment to prepare the pipe for effective lining.

Length of Pipe

  • Lining can be installed up to 600’ in length

Small Diameter “In-House” Rehabilitation

“In-house” pipe rehabilitation refers to pipe rehabilitation where the pipes are generally smaller in diameter relative to municipal sewer pipe.

Just like traditional pipes, the combination of age and corrosion take their toll; resulting in cracks, leaks and blockages. Fortunately, replacement is no longer the only solution. In-House Pipe rehabilitation is less invasive and more cost-effective. This system is affective in homes, apartment and office buildings and many other commercial structures that contain standard plumbing systems.

Small Diameter “In-House” Rehabilitation Services

Inspection and Cleaning
Critical to a full rehab is the effectiveness of the cleaning. TPR uses proven Picote Millers and high-speed cleaning tools for a fast and effective solution.

Pipe Coating
Leverages the Picote epoxy brush coating system for pipes ranging ¾ inch to 2 inches in diameter.

Pipe Lining
Our CIPP solution is recommended for pipes ranging 2 inches to 9 inches in diameter.

What types of pipes and drains fall under “in-house” rehabilitation?

  • Vertical Stacks
  • Soil Stacks
  • Waste Stacks
  • Vent Stacks
  • Rain Leaders
  • Branch Lines
  • Horizontal Sewer Pipe
  • Cast Iron
  • Clay
  • PVC

Lateral Connection Sealing

  • The TYGERPatch Lateral Seal System

The TYGERPatch Lateral Seal System, powered by our Schwalm robot, creates a 360º or 180º CIPP Tee and Lateral connection installed from the main during live flow using the nearest manhole. The system is designed with non-shrinking components, mechanically bonds to all pipe types and is a proven long-lasting solution even in the most aggressive sewer conditions. The TYGERPatch lateral seal is designed to extend 8” into the lateral.

Pipe Sizes:

  • 8” – 12” in diameter for Main Lines
  • 4” – 8” in diameter for Laterals

Extending Green Initiatives
The lateral connection seal systems utilize the most environmentally friendly process and materials available. This environmental consciousness extends all the way down to the choice of resins used. Unlike competitive resins, the silicate resins we use are non-toxic and non-odorous, containing no noxious styrenes or esters or volatile organic compounds (VOC).

Lateral Lining

Via an opening in the sewer, water pipes or drain lines, our technology inserts an epoxy coated liner and inverts it until the resin coats the inside of an existing pipe

It takes roughly 3 hours to cure and is underpinned by third-party tested and certified pipe lining materials that meet or exceed the specifications and standards set by ASTM. This means our materials will exceed a 50-year life-span and are environmentally friendly.

Geopolymer Lining

A Geopolymer is a formulated mortar comprised of aluminosilicate powder with an alkaline activator to form a monolithic mineral polymer with ceramic properties. A geopolymer is not an epoxy or a plastic blended with aggregate.

GeoKrete® Geopolymer cures through a process of polycondensation and possesses proven, high early and long-term compressive strength. Additionally, with superior bond strength, GeoKrete liners can be applied in layers and under multiple mobilizations. The chemical composition of GeoKrete Geopolymer makes it inherently resistant to the microbial induced corrosion prevalent in many sewer environments. Geopolymers contain greatly reduced concentrations of calcium hydrates, commonly found in cementitious mortars, furthering the suitability of GeoKrete in low PH environments.

Features & Benefits

  • Precision blended and mixed material allows for high measures of quality control
  • Forms a monolithic, inorganic polymer structure for much higher resistance to acids and greater surface durability
  • Cures through polycondensation and bonds to itself — the liner can be applied in layers and under multiple mobilizations
  • Easily navigates pipe deformities, deep pipes, pipe bends, non-round pipes, slopes and separated joints

Typical Applications

Pipes, culverts, and tunnels greater than 30 inches:

  • Corrugated metal
  • Concrete
  • Brick
  • Stone
