Insituform® CIPP
Our Insituform® process is the most widely used trenchless method for restoring structural integrity to and removing infiltration from sewers. It has been proven in pipes with a wide range of shapes and in diameters of up to nine feet (2.75 m). In the Insituform® process, a resin-impregnated Insituform® tube is installed into a damaged sewer. This process results in a seamless, jointless ``pipe-within-a-pipe`` with a smooth, continuous inner surface which usually increases flow capacity. We typically complete installations in a single day, using robotic methods to restore active connections from within the line.
Every aspect of our process has been proven through years of use. Our resins have been tested and proven for sewer applications. Our equipment has been specifically designed to ensure safety and achieve peak product performance. With new innovations and enhancements added each year, our Insituform® process is the most dependable and cost effective in the industry.
In addition to main line sewers, our Insituform® process is used to rehabilitate service laterals and seal connections working only from inside the main line. Our Insituform® Trenchless Point Repair™ process can be used to repair localized structural problems in otherwise sound pipe.
Insituform ArmorGRiP™
Insituform ArmorGRiP™ Panels is a product for rehabilitating large gravity sewers and drains with fiber reinforced, filled, thermoset resin panels. It is cost-effective for sewers with equivalent diameters ranging form 54- to 144-inches and even larger in some applications. Because it is a custom-fit solution, it can be installed in sewers of any shape, including:
• Round • Square
• Oval • Horseshoe
• Rectangle • Egg
The panels are manufactured in a factory setting using MVI™ technology (patent pending). Panels can be manufactured in full 360-degree segments or two or more panels can be fitted together to form one 360-degree segment.
Advantages
Insituform ArmorGRiP™ Panels provide a strong, durable, sewer rehabilitation product that can resist groundwater, soil, and traffic loads for 100 years. By increasing either wall thickness or fiber reinforcement, Insituform ArmorGRiP™ Panels can be designed to accept nearly any external load a sewer receives. It can also withstand temporary sewer surcharge loads. This process, which can negotiate bends, is ideal for sewers that change in shape or size. It is an economical solution for large diameter gravity pipes.
Installation
It is a man-entry procedure where panels are fitted together right in the sewer to form a full segment , taking the shape of the original host sewer. Then, the annular space between the Structural Panels and the host sewer is filled with grout to complete the installation.
Insituform CP™ (Composite Pipe)
Insituform CP™ is a high-strength, fiber reinforced composite CIPP gravity pipe product that can be used in the 24``-60`` equivalent diameter range. Its unique ``sandwich`` wall construction provides the same long-term structural value as the non-reinforced Insituform® CIPP product with about half the pipe wall thickness. Insituform CP™ offers excellent structural integrity in circular and non-circular pipe reconstruction.
Materials & Structure
Insituform CP™ is reinforced with carbon fiber and/or corrosion resistant fiberglass materials. The design locates the structural reinforcing materials where they are needed, separated by traditional CIPP material. The Insituform CP™ wall design optimization can reduce the required thickness by about half. As with the traditional inversion Insituform ® CIPP product, there is a polyethylene coating on the inside pipe surface.
Insituform CP™ provides a seamless, jointless ``pipe-within-a-pipe`` that restores structural integrity to and removes infiltration from sewers. It can be inverted into pipes with a wide range of shapes and can navigate bends similarly to Insituform ® CIPP. The thinner wall product is ideal for stabilizing odd-shaped brick sewers by providing the required structural support. Its reduced wall thickness and continuous inner surface provide increased flow capacity relative to the host pipe and more conventional rehabilitation products.
The reduced wall thickness of Insituform CP™ allows a greater length of tube to be impregnated with resin, ``wet out,`` in a factory setting and transported to the jobsite. At the jobsite, the longer tube lengths reduce the number of inversions allowing projects to be executed more rapidly. For similar reasons this product also minimizes the use of on-site wet out requirements, which can make projects more cost-effective.
When projects require setting up in congested traffic environments or within limited access easements, the opportunity to extend the installation limits to reduce project risk or interference can be better provided using the Insituform CP™ product.
Insituform CP™ is an economical solution for medium-sized diameter gravity flow pipes. Insituform CP™ is installed using the inversion process.
Thermopipe®
A polyester-reinforced polyethylene lining system used for the trenchless rehabilitation of water distribution mains and other pressurized systems up to 8-inches in diameter. Thermopipe has a long-term independent internal pressure rating of up to 230 psi. Can navigate most bends.
Thermopipe solves severe internal deterioration problems and improves water quality by providing a continuous, impermeable pressure pipe lining inside the host pipe. It can navigate most bends and allows existing services to be reconnected with new factory-manufactured fittings. Thermopipe minimizes installation time and on-site disruption.
