Pipebursting
A semi- trenchless method of installing factory-manufactured pipes and service connections in place of severely damaged water, sewer and commercial pipes and service laterals. An ideal solution for upsizing capacity of existing lines ranging from 6 to 36 inches in diameter.
Advantages
Because it requires minimal excavation, pipebursting is a preferred solution for installing new pipes in high-profile areas where disruption to surrounding businesses, resident and the environment is an important consideration. It also reduces overflow in wet weather and minimizes the need for bypass pumping.
Slip Lining
A trenchless method of installing new factory-manufactured pipe and service connections inside existing sewer, water and commercial lines. Accomplished by pulling a new liner pipe into the existing pipe, creating a slight decrease in the inside diameter. Best for pipes ranging from 8 to 96 inches in diameter.
Advantages
Sliplining can be performed rapidly, without disturbing adjacent services or requiring bypass pumping. It makes it possible to repair long lengths of pipe with minimal disruption. Because the liner is structurally sound, it solves problems related to leakage and structural deterioration.
Microtunneling
A trenchless method of constructing new sewer and water pipe without requiring man-entry. Typically used for pipes ranging from 18-inches to 54-inches in diameter and 40- to 50-feet in depth.
Advantages
Our microtunneling method uses a ``closed system;`` water and mud removed from the ground are separated, decreasing the risk of environmental contamination. Because we complete microtunneling projects using safe, laser-guided equipment, there is minimal disruption to surface activities. Microtunneling is particularly effective in below-groundwater conditions and unconsolidated soils and where above- and below-ground obstructions exist.
Pipe Jacking
A specialized, man-entry tunneling method used to install new factory-manufactured pipes with minimal surface disruption. While used primarily for new sewer construction, it also can be used to rehabilitate and reline sewers and other pipe systems with diameters ranging from 54- to 120-inches.
Advantages
Pipe jacking is an economical alternative to and much less disruptive than using open-cut construction to install new underground pipes. Because it is performed with a closed system, pipe jacking decreases the risk of environmental contamination during construction.
Shotcrete
A technique used to rehabilitate large-diameter sewers ranging from 6 to more than 20-feet in diameter that cannot be cost-effectively rehabilitated with sliplining or cured-in-place pipe. Entails spraying a concrete coating to the interior surface of the structure being rehabilitated. Also an excellent solution for odd-shaped sewers, manholes, vaults, pumping stations and other concrete and brick structures.
Advantages
The shotcrete process effectively seals old concrete or brick to lengthen the service life of the existing structure. Resembling precast concrete when complete, it produces successful, long-lasting results.
Tunneling
A method of constructing new large-diameter pipelines in busy urban areas and challenging geological conditions. Because tunneling requires man-entry, it is ideal for construction of large-diameter tunnels, ranging from 5- to 26-feet in diameter.
Advantages
Tunneling is an economical, long-term solution for increasing the capacity of an existing wastewater and storm water collection system. It is often the best method for transporting large volumes of water. By eliminating the need for pump stations, new interceptor and relief tunnels can save millions in utility costs over the long term. Insituform® has the state-of-the-art equipment and expertise to work in a broad range of geological conditions.
Manhole Rehabilitation
SprayWall® is a spray-applied, cured-in-place manhole rehabilitation process. We use it to solve infiltration and groundwater problems in manholes by creating a durable, corrosion-resistant ``manhole-within-a-manhole`` that is designed to withstand hydrostatic pressure from groundwater. Often completed in conjunction with other rehabilitation projects.
Advantages
Because SprayWall® is applied tin a fast, one-step process, downtime and traffic disruption are kept to a minimum. Once the installation is complete, the manhole can be returned to service immediately, typically eliminating the need for bypass pumping.
Video Inspection Services
A method of evaluating and creating a permanent video record of underground pipe conditions. Insituform® will conduct evaluation video inspections for communities that wish to assess the overall condition of their pipe systems and develop priorities for repair programs. Preliminary inspections are completed immediately preceding a repair project to ensure the line is free of debris and to create a record of the line`s open and capped service connections. Following completion of a project, a post inspection video is shot to provide a permanent record, both of the repairs themselves and of the service connections that have been reinstated.
Advantages
Insituform® has one of the industry`s most flexible and technologically advanced video inspection systems. All new video footage is recorded digitally and downloaded to a central library, where it can be converted to the format (CD, DVD or VHS) that best meets each customer`s documentation needs. To ensure consistent high quality, all of Insituform®`s videos are reviewed by a team who has completed training from the National Association of Sewer Service Companies, an organization dedicated to developing standardized codes of sewer observation. With nearly 100 television crews throughout North America, Insituform® has the capacity to handle inspection assignments of all sizes.
PE Close-fit
A high-density polyethylene lining method of rehabilitating potable water transmission mains and other pressurized systems. Ideally suited for larger-diameter pipes of 16 to 48 inches in diameter.
Advantages
This solution created a tight-fitting, jointless pipe that can be installed in long lengths. While stopping leaks and preventing further corrosion in structurally sound piping, this process offers the money-saving benefits of polyethylene pipe and eliminates flow capacity reductions common in other rehabilitation methods.
