2 About Us An HDPE after mechanical insertion into an egg-shaped brick work sewer sized 1400 x 2100 mm (or 56 x 84 inch) I. D. Following insertion the is inflated to the defined pressure to fit closely against the existing surface. Who we are... History of Trolining Trolining GmbH, a medium-sized company located in Troisdorf / Germany, is recognized as a leader worldwide in the field of trenchless pipe rehabilitation. Trolining started operations in the late 80 s, serving the German sewer market as a business unit of plastics processing giant Hüls Troisdorf AG. An ambitious development program was started at this time with the goal of creating a lining method for pipes satisfying key requirements for transport of wastewaters and in particular highly polluted wastewaters: - guaranteed 100 % water-tightness - outstanding chemical and environmental resistance - high cost efficiency, long service life. HDPE was the obvious material choice based on its successful track record spanning over 40 years in highly demanding lining applications in the landfill, tunnel and water engineering sectors. The TROLINING process was developed in 1992; Trolining began operations as an autonomous company in the same year. In 2004 Trolining was sold by HT TROPLAST AG to private investors and the company underwent further streamlining, utilizing advanced management techniques to operate in even closer accordance with customers needs. Our established worldwide network of sales and installation partners has served local markets successfully for many years. TROLINING ready-toinstall liners are fabricated exclusively at our Troisdorf facility, ensuring consistent quality. Offering a broad range of capabilities and resources, Trolining GmbH is in a position to satisfy users requirements however diverse they may be.

Section lengths of up to 200 m are available depending on the specific line I. D. to be rehabbed. This innovative lining system incorporates special floor texturing which provides outstanding self-cleaning and substantial maintenance savings in long-term operation. Deposits on the liner surface are swept-up through turbulences created by the texturing and transported off downstream. The floor texturing also provides improved footing and enhanced safety for workers within the line. Installed TROLINING Self-Cleaning System in a 800 mm (or 32 inch) I. D. line.

4 TROLINING Systems TROLINING systems are available for a wide variety of application requirements, permitting cost-effective solutions even for complex rehabilitation problems. Basic System System Double System Lateral connections Lateral Epoxy sock Inverted saddle Electrofusion wire Basic System System Double System Lateral Connections The heart of the TROLINING pipe rehabilitation system is the, an HDPE liner with specially designed embedment studs on its outer surface. Following fabrication and QC testing in the production plant, the is transported to the site and drawn into the host line, providing a smooth inner surface which is ideal for fluid conduction. The annular void between the host pipe surface and the is filled with TROLINING injection grout, the. The grout permeates into the existing surface, completely filling voids caused by cracks, loose fragments and deteriorated joints of brick work sewers. The direct full-surface bond between the and the host pipe surface ensures secure placement and also prevents thermal expansion as encountered in conventional polyethylene liners. In steel and reinforced concrete pipelines, the grout provides further benefits as its alkalinity provides effective protection against corrosion. With the TROLINING System, a which is smooth on both sides is inserted into the line prior to installation of the studded. This creates a defined annular void volume which is sealed on its inner and outer surfaces, permitting exact definition of the injection grout volume required to fill the system wall. The System is used in rehabilitation of lines with lateral connections to prevent obstruction or closure of the laterals with the grout. If the pipe to be rehabilitated is near or below groundwater level, the System is required to ensure dilution-free grouting. Encapsulating the rehabilitated line, the effectively prevents inward seepage of groundwater, rainwater run-off as well as chemical pollutants. Double-liner systems are used in applications requiring additional structural load-bearing capacity and high-security containment. These systems are made by combining Basic and / or Systems concentrically as required. Installation of each system layer is carried out separately, even for large-diameter and specialty systems. The peripheral grouting around each layer bonds it securely to the adjacent outer layer, resulting in an interlocking PE / concrete composite structure. In addition to conventional connection methods such as grout or resin injection and open-cut installed PE or PVC saddle flanges, Trolining offers the following state-of-the-art solutions for lateral connections: Inverted HDPE saddle After reopening of the lateral line, an inverted HDPE saddle is inserted and welded to the installed liner system with defined parameters and geometry by means of integrated electrofusion wires. The connector incorporates a fabric sleeve which is impregnated with a 2-component epoxy resin and joined to the lateral line. A robotic welding module carries out welding, applies contact pressure and accelerates curing of the impregnation resin. Manual Connection with PE Pipe Section A PE pipe section with custom-made dimensions for the connection at hand is inserted into the lateral line and connected to the liner system by an extrusion welding seam. Circumferential grooves cut around the pipe section ensure secure mounting of elastomeric and / or expansion sealing gaskets. 6 7

5 Placement of an inflatable sealing plug into an inserted What we do... The TROLINING trenchless pipe rehabilitation system is based on various HDPE liner components which can be combined in a wide range of alternative configurations. The heart of the system is the with its V-shaped embedment studs. The annular void created by the studs is filled with, a specially engineered injection grout. This high-strength grout fixes the permanently in place and provides the load-bearing shell of the system. The system is suitable for lining of pipes ranging from 250 mm to 2000 mm (or 10 to 80 inch) I. D., regardless of whether the line cross-section rehabbed is circular, egg-shaped or a special geometry. HDPE corner guide Hydrostatic/pneumatic pressure source Injection grout infeed Hydrostatic/ pneumatic pressure head Vent line Pressure head in compliance with EN 1610 Segmental lining sheets are offered for rehabilitation of lines greater than 2000 mm (or 80 inch) I. D. and of elbows and corners in man-sized lines. Inflatable plug Water Water Annular void Schematic diagram of liner insertion: The pipe section to be rehabilitated is plugged off at both ends, cleaned and visually inspected. A cable winch is then used to unroll each HDPE liner from its transport drum and draw it through the line into position. Schematic diagram of annular void grouting: The HDPE liners are drawn into position and welded securely together at both ends. They are then inflated with a specified hydrostatic pressure. Air can also be used in place of water as the inflation medium in small diameter lines. Inflation is done through passages in the temporary plugs closing the ends of the line section. When the required inflation pressure is attained, the annular void is filled with TROLINING injection grout fed from the down stream end. 8 9

6 Robotic Systems Rehabilitation of non-man-sized lines in the range of 250 to 600 mm (or 10 to 24 inch) I. D. is done with the aid of proprietary robot technology which executes cutting and lateral connections in accordance with stateof-the-art standards. Exceptional connection quality is achieved with our inverted HDPE saddle.
