1 GRUNDOCRACK PNEUMATIC PIPE BURSTING SYSTEM PIPE BURSTING SUCCESS STARTS HERE TT Technologies is the world leader in pipe bursting equipment and experience. For over 20 years contractors have relied upon GRUNDOCRACK pipe bursting systems to help them refurbish failing infrastructure. Superior quality materials and unparalleled experience go into each GRUNDOCRACK pipe bursting tool.

2 The Proven pipe bursting system Bursting Success For Gas, Water, Sewer, Power & Telephone Since 1980, thousands of miles of pipe have been successfully replaced using pipe bursting equipment from TT Technologies. In fact, over 90% of pipe bursting projects in North America have been accomplished with a pneumatic system like the GRUNDOCRACK system from TT Technologies. The GRUNDOCRACK system is effectively used where existing pipes are undersized or have failed beyond the possibility of point repair. Cost Savings 90% of the pipe bursting projects worldwide have Projects using the used a PNEUMATIC system pneumatic pipe like GRUNDOCRACK bursting method with GRUNDOCRACK cost less than open trenching. The savings are not limited to direct project costs, but also include positive social factors like minimal surface disruption that keeps traffic flowing and landscaping intact. This is especially beneficial in neighborhoods, busy Replace size-for-size or urban areas as well upsize with: as environmentally PE pipe sensitive areas. PVC Fiberglass Use GRUNDOCRACK for the replacement of these utilities: Gas Water Sewer Telephone Power The Process Simple, Effective Process During the pneumatic pipe bursting procedure, the GRUNDOCRACK is placed into the host pipe at an entry pit or manhole. A constant tension GRUNDOWINCH, based at the exit area pit and attached to the head of the tool, guides it through the host pipe. Continuous percussion from the pneumatic tool fractures the host pipe. The combined effect of the percussive action of the GRUNDOCRACK and constant tension from the GRUNDOWINCH enables the tool to effectively hammer its way through the host pipe, displacing the fragments into the surrounding soil, while simultaneously pulling the new pipe, usually High Density Polyethylene (HDPE), into place behind it. The GRUNDOCRACK can be used to burst fracturable pipes such as cast iron, clay, concrete, RCP, ABS and some plastics. GRUNDOCRACK pipe bursting tools are capable of bursting and replacing pipe from 4 inches to 60 inches in diameter. Each tool is effective in bursting a wide range of pipe diameters through the use of a variety of expanders. Pipe bursting is the only trenchless method of replacement that allows for the upsizing of the original pipe. The GRUNDOWINCH : A Constant Force in Bursting The GRUNDOWINCH is the premier pipe bursting winch in the industry and is essential to bursting success. The constant tension, variable speed GRUNDOWINCH makes adjustments for conditions that affect line speed during operation, providing constant and consistent pulling force and preventing slack from developing in the line. That is especially important for projects point repairs. When the bursting tool reaches a repair it slows down as it works its way through. After the repair is burst, Pneumatic pipe bursting with GRUNDOCRACK is like driving a nail through wood with a hammer. Repeated blows progress the nail through straight and clean.

3 The percussive action of the GRUNDOCRACK effectively bursts the host pipe. An expander attached to the tool displaces the fragments into the surrounding soil while the new pipe is pulled in simultaneously. there is less resistance and the tool speeds up quickly. The GRUNDOWINCH s exclusive design incorporates twin capstans with twin motors and gearboxes to protect the cable and cable drum from extreme stress levels. Guide Head: A Guide to Bursting Success Years of TT bursting experience has led to the development of guide head technology. Use of a guide head can be instrumental in the success of a bursting job especially involving cast iron pipe. Cast iron pipe tends to break several feet in front of a standard pipe bursting tool. This causes the potential for two major problems. First, the shards of cast iron pipe are sharp and can actually cut winch lines. Second, pipe fragments can build up making the host pipe impassable. This can cause the tool to change direction and veer off course. can be used in conjunction with a guide head, allowing the tool to successfully burst difficult host pipes, like cast iron as well as many point repairs like PVC. GRUNDOMUDD : Making Sure Bursting Goes Smoothly The GRUNDOMUDD is another important component in pipe bursting operations. The GRUNDOMUDD mixes and delivers bentonite lubrication to help reduce friction during the pipe bursting process. The weight of large diameter HDPE, as well as the depth of the host pipe contribute to pipe bursting friction. Some soils, like beach sand, will not remain in the expanded state long enough for the installation of new product pipe. The GRUNDOMUDD is also used in these situations to help maintain the annular space created as the tool travels through the host pipe. GRUNDOCRACK bursts: Clay Concrete Cast Iron PVC A guide head attached to the front of the GRUNDOCRACK pipe bursting tool adds needed tool length, allowing the tool to get into the pipe and break it at its weakest point, the inside. Besides adding tool length, the guide head helps protect the winch line. Cutting blades The completely self-contained GRUNDOMUDD is a high performance pumping unit. With the ability to mix and deliver fluid lubricants, the GRUNDOMUDD is ideal for providing the Bentonite lubrication needed for difficult bursting operations.

5 Versatility for specialty applications Reverse Removal GRUNDOCRACK straight barrel tools (PCG) can be reversed automatically with a quick throw of a lever on the in-line lubricator. Once the burst is complete, the expander is removed and the tool is reversed out through the newly installed PE pipe. Eliminating the need for an exit pit, this method is perfect for bursting to a manhole or from manhole to manhole. The speed and convenience of this method can reduce costs dramatically in many applications. Proven Method Since ;@ ;@ ;@ ;@ 1 2 Straight barrel tools are ideal for samesize bursting including 6-inch through 18-inch diameter pipes. A one-size upsize is also possible with the correct front expander configuration. Eight different size diameter straight barrel tools are available from TT Technologies with automatic reverse capabilities. ;@ ;@ 3 Lateral Bursting Experts For replacing lateral connections, small GRUNDOCRACK tools can be launched from the confined space of a manhole. A variety of pneumatic and hydraulic winches are also available for manhole applications and tight working areas. The GRUNDOCRACK can pull in a variety of lateral replacement pipe, including polyethylene, PVC, and fiberglass. ;@ ;; ;; ;; Manhole Removal GRUNDOCRACK tools help limit disruption to traffic and city streets by offering contractors a trenchless means for pipeline rehabilitation and replacement. MINI-GRUNDOCRACK tools allow contractors to utilize manholes as launch and exit pits for bursting operations. The tool is easily positioned inside of a manhole to begin the bursting run. When the tool completes the burst it is quickly removed through the next manhole eliminating the need for additional pits. ;@ ;@ GRUNDOCRACK tools are protected by Advantica patents.
