Products and Services

A leader in providing environmentally solutions, in 2009 IPR was ranked No.4 on the Crain's list of largest Environmental Companies for best practices in green technology, including our non-invasive Expanda spiral-wound lining technology, which rehabilitates existing pipes from above ground without releasing harmful chemicals into the environment. IPR's dedication to excellence was recently recognized when the company received the prestigious INC Award.

The innovative trenchless pipe rehabilitation methodologies provided by IPR are more cost-effective and less intrusive than traditional open cut pipeline repairs. Trenchless rehabilitation technologies allow for the completion of underground repair or replacement projects with minimal disruption to surface traffic, nearby homes and businesses, or environmentally sensitive areas. Industrial infrastructure repairs and maintenance require many of the same skill sets and capabilities that IPR uses in its municipal end market. Currently, IPR is working with several large industrial companies, including oil and pharmaceutical organizations. In addition, IPR has expanded its efforts into the Department of Transportation sector where our technologies and expertise are being put to work in the area of highway repair.

 

Environmentally Friendly Solutions

Cities seeking to reduce waste-water treatment expense desire a cost-effective alternative to sewer pipe replacement and above ground repair of leaking pipes, and aging storm drains and culverts. Both the public and private sector are seeking an environmentally friendly solution which minimizes the disruption to the environment. This solution is known as "RibLoc."

The pipeline is first cleared of debris and obstructions. The Expanda Pipe winding machine is lowered into the access chamber. HDPE or PVC profile is then spirally wound into the host pipe. The process continues until the liner has been expanded for the full length of the deteriorated pipeline. All RibLoc lining technologies provide a seamless, watertight structural liner resistant to chemical attack and corrosion.

Sizes:  RibLoc offers both close fitting and fixed diameter pipeline solutions ranging from 6” to over 100” in diameter.

The revolutionary spiral wound process provides a cost-effective structural renewal solution for aging sewers, storm drains and culverts.  To date, RibLoc has been utilized to rehabilitate more than 4 million feet of buried pipelines in over 30 countries.

RibLoc offers both close fitting and fixed diameter pipeline solutions ranging in diameters from 6” to over 100” and are available in PVC and HDPE.  Our close fitting solutions include Expanda Pipe, which is applicable for pipelines ranging from 6 to 30 inches.  For pipelines 32 to 76 inches, we offer Rotaloc.   For fixed diameter sliplining applications, we offer Ribline.  All RibLoc lining technologies provide a seamless, watertight, structural liner resistant to chemical attack and corrosion, and can be installed in live flow conditions.

The Expanda pipe lining system consists of a single strip of PVC which is spirally wound into the existing pipeline via a patented winding machine positioned in the base of a manhole or access chamber.  The edges of the strip interlock as it is spirally wound to form a continuous watertight liner inside the host pipe.  Once installed, a patented process is used to expand the liner to fit tightly against the inside wall of the host pipe.  The ends of the liner are sealed and rendered to make them smooth with the host pipe.  Lateral connections can be immediately reinstated. 

The Rotaloc process is a solution for restoring hydraulic efficiency, reliability and integrity of aging sewers, storm drains and culverts.  The Rotaloc winding machine progressively winds PVC profile inside the host pipeline.  The edges of the profile are interlocked forming a continuous watertight liner.  The Rotaloc winding machine can alter diameter as it traverses the pipeline to produce a liner of optimal diameter.  Rotolac liners can structurally rehabilitate brick, concrete, glass reinforced plastic or corrugated metal sewer and storm water pipelines.

The Ribline system consists of a single strip of steel reinforced HDPE profile which is wound into the existing pipe by the Ribline machine.  The process continues until the liner reaches the end of the pipeline.  The edges of the profile are welded together by the Ribline machine, forming a continuous watertight liner.  The fully encapsulated steel reinforcement is designed to provide a liner of optimum stiffness and structural integrity.
