Slip-Lining
Slip-lining is the backbone of our company. Slip-lining is defined as the process of rehabilitating a structure by inserting a new structure into the existing opening while maintaining or increasing the structural and hydraulic capacity of the original structure.What differentiates us from others is that we can not only perform the installation for all manner of slip-lining projects, but we can assist you in determining the right slip-lining solution for your specific need. Factors to consider that we will take into consideration are:
• Structure size, length, and accessibility
• Hydraulic considerations and open end area
• Depth of cover and height of ground water
• Desired lining material
• Budgetary concerns

Grouting
Grouting is the secret to a successful slip-lining operation and part of the secret to our success. Slip-lining a structure and not properly grouting is the equivalent of putting a bandage on an internal wound. To understand the importance of grouting, one must first understand the purpose of grouting. Grouting not only fills the annular space between the existing structure and the liner, but it also fills all the voids that are almost always present on the outside of the structure. As part of the deterioration process, voids form outside of the structure. Road failures are much more often a result of the voids than the actual structure failing in a structural capacity.Grouting is not only essential, but it is also a highly specialized procedure that must be performed with a high level of expertise. Our grout crews install tens of thousands of cubic yards of grout every year. We often design our own grout mixtures based upon the design considerations of the lining material. It is imperative to have an experienced crew performing the installation to both fill all the voids but also to ensure the structure does not deflect or collapse. In the last 10 years, we have successfully grouted more slip-lining projects than any other contractor. Indiana Reline, Inc. grout crews have performed a considerable amount of grouting for pipe abandonments and bore hole stabilizations.

Spiral Winding
Spiral Winding is a process that has been used worldwide for over 25 years. Indiana Reline, Inc. has become the pioneer for Spiral Winding in the United States. Spiral Winding is a slip-lining methodology for limited access applications. Situations such as; manhole to manhole, Right-of-Way infringement, wetlands, and other environmental friendly applications. Indiana Reline, Inc. has proposed and successfully installed Spiral Wound liner pipe in which no other liner pipe could be used due to sight conditions. Spiral Winding typically provides a larger open end area than comparable solutions, which is beneficial when there are hydraulic concerns.[ Back to Top ]
Pipe Bursting and Ramming
Slip-Lining is a very affordable, long-term solution, but it is not always a viable option. In cases where the existing structure is in such a state of failure that it can not be relined, pipe bursting or ramming is a great solution. Both of these processes are ways to rehabilitate a failed or misaligned pipe.[ Back to Top ]
Horizontal Auger Boring
Horizontal Auger Boring (HAB) is a trenchless technology that allows for the placement of a sewer in a location where an open-cut solution is not feasible, such as; under a highway or building. HAB involves the forming of a bore from a drive pit, by means of a rotating cutting head, and installing a steel pipe that serves as a sewer casing. The process begins with the construction of a temporary horizontal jacking platform with an alignment track in a drive pit at a desired elevation. The casing pipe is then jacked while soil is excavated at the same time.[ Back to Top ]
Hand Mine Tunneling
Hand Mine Tunneling is a viable option to consider when needing to mine an tunnel in the 42" to 60" range. Hand Mining generally uses the finished pipe product as the tunnel liner. Hand Mining is normally limited to reasonable ground conditions in the following soil types: rock - soft or hard, clay, and stiff sand & gravels. In all ground conditions, hand mining is safer and more efficient if it is done from within a shield. The shield not only protects the men but also allows for more control over the "heading" of the tunnel. Many shield can be steered either mechanically or with hydraulic power.[ Back to Top ]
Shotcrete Stabilization
Shotcrete Stabilization is a process that can be taken advantage of to stabilize structures. Shotcrete consists of applying concrete/mortar pneumatically via a pressure hose at a high velocity onto a surface. Shotcrete undergoes placement and compaction at the same time due to the force with which it is projected from the nozzle. It can be impacted onto any type or shape of surface, including vertical or overhead areas.[ Back to Top ]
HDPE Fabrication, Welding, & Fusion
We often deal with situations in which there is a need to custom fabricate a solution. Some of the custom fabrication we have performed include navigating turns in pipes, flow dissipaters and diffusers, wild-life fish ladders, and more.Many large diameter HDPE liner pipe require either an electro-fusion or extrusion welded joint be completed prior to installation. All supervisory and field personnel are certified electro-fusion and extrusion welders. Other projects may require the use of a butt fused joint prior to installation, and again all supervisory and field personnel are certified in butt fusion technology. We can offer these services upon request.

Valve Exercising
Every water system has valves - devices that regulate, stop, or start the flow of water in the distribution lines. Being able to operate these valves at a moment's notice is extremely important. In an emergency, sections of a distribution system may need to be shut down without delay. However, if a valve is not used over a period of time it can seize-up from corrosion and get stuck, making the valve inoperable. A regular valve exercising program will help to eliminate these problems.[ Back to Top ]
Dewatering
Culvert pipe and sewer line rehabilitation generally involves flowing water. Many of Indiana Relines' slip line solutions can be completed under normal flow conditions some, however, require diversion or de-watering of the culvert or sewer. Indiana Reline, Inc. has installed de-watering solutions such as cofferdams, inflatable dams, manhole to manhole bypass pumping, and diversion pipes in lengths of up to ½ of a mile. Indiana Reline, Inc. has the experience, personnel, and equipment to handle de-watering and/or water diversion on many projects.[ Back to Top ]
