Sag correction system

The Sag Correction System from Advanced Construction Products is a three-section machine assembled inside the manhole that uses a combination of high-frequency vibration and an internal lift mechanism to raise the pipe and remove low spots in PVC sewer lines, eliminating excavation. Intense vibration allows the pipe bedding material to flow around and underneath the pipe as it is lifted. Sags of any length can be removed by moving the machine in increments and lifting the length of the sag. The system corrects sags in 8-, 10- and 12-inch-diameter pipe. 503/359-4670; www.advancedconstructionproducts.com.

Composite pipe wrap

ENECON's DuraWrap composite is a combination of high-performance polymers and carbon fiber technology designed to repair, rebuild, reinforce and restore the integrity of often severely deteriorated piping, tanks and other fluid flow systems, extending their service life and eliminating the need for replacement.

The wrap system can be applied to the interior and exterior of piping and equipment to seal and strengthen the components. When applied to the interior walls of underground and other inaccessible piping, the wrap can repair and restore pipe integrity without excavation or replacement. 888/436-3266; www.enecon.com.

Service line tool

The Wedge service line replacement tool from Footage Tools is a low-cost alternative to open-trench methods for replacing defective 3/4- to 1-inch water services. Users make small entrance and exit pits, then insert a 3/8-inch aircraft cable through the existing water service and connect to a single-edge Wedge SE (for copper and galvanized pipe) or triple-edge Wedge (for PVC and PE pipe). The back of the unit offers adapters to connect the new service line. Users attach the cable grip, then connect it to the bucket of a backhoe or heavy-duty winch and begin pulling or splitting out the old service and replacing the new service at the same time. This method adds value by minimizing the costs of replacing landscaping. 888/737-3668; www.footagetools.com.

Slide rail system

The Slide Rail Shoring System from American Shoring can be used in a number of configurations, including for the bore pits commonly used to bore under roadways, streams or other obstacles.

The system can also be equipped with a doghouse panel to accommodate the casing pipe. 800/407-4674; www.americanshoring.com.

Reinstatement cutter

The Dominator 430 from Bowman Tool Company is a reinstatement cutter designed to operate in 6- to 30-inch relined pipe. Performance is improved by the unit's streamlined design because there is no external air tube, and its stability in the pipe because of its 72-pound construction from a solid billet of stainless steel. The cutter's head assembly incorporates a pinionless, quick-change design and one adjustable gib to reduce adjustment time and maintain accuracy. Lateral reinstatement is achieved with the 0.8 or 1.2 hp cross flow air motor. For optimum cutting performance in 8-inch and larger pipe, the 2.5 hp geared air motor can decrease reinstatement time by about 80 percent.

Maintenance is simple because the unit can be disassembled and reassembled in about 30 minutes with only eight moving parts. All electric motors are isolated at the end of the cutter in a watertight chamber eliminating water-damaged motors and allowing for easy and quick access. The unit is made of temper-hardened stainless steel and bronze enabling it to cut tough liners, including UV-cured lines. 717/432-1403; www.bowmantool.com.

Internal joint seal system

The HydraTite internal pipe joint seal from Cretex Specialty Products is trenchless remediation for the repair of pipe joints. It eliminates infiltration and exfiltration with a mechanical seal that has a rubber seal (EPDM or nitrile) spanning the joint and steel retaining bands. Each seal is custom-made to ensure compliance with project specifications. The system can be used in almost any type of pipe (iron, concrete, clay or plastic) from 24 to 216 inches in diameter. Seals are available in 11-, 14- and 21-inch widths.

Retaining bands are made from carbon steel, 304 stainless, 316L stainless or AL-6XN. The thickness of the bands varies with the size of the seal. A stainless steel backing plate can be added behind the seal for added support when spanning voids in the pipe wall, such as the remediation of expansion joints, sealing off abandoned laterals, or when repairing deteriorated joints. The joint seal system is able to withstand the corrosive effects of hydrogen sulfide and offers a cost-effective alternative for small repairs where structure of the pipe is not compromised. 800/345-3764; www.cretexseals.com.

All-terrain drill

The JT30 All Terrain horizontal directional drill from Ditch Witch is equipped with a 119 kW, Tier 4i engine. The machine operates with high efficiency with full power available to all functions.

Relining system

Prep From The Main from LiquiForce allows for relining of sewer laterals without the cost, inconvenience and liability associated with the installation of a clean-out. The system enters through the manhole and traverses to the point of the lateral connection. From this location, various cleaning, video inspection and measurement tools are inserted as far as necessary up the lateral to prepare it for lining. Each of these processes takes only a few minutes and many laterals can be readied for lining in an eight-hour shift.

The data is immediately transferred to the manufacturing facility (via the Web) for liner production, without copying and errors. The system operates in various sizes of mains and negotiates laterals from 4 inches and larger. The system follows the cleaning equipment down the main from the manhole to the lateral, where it sends a custom-built liner up the lateral and attaches it to the main with a gasketed seal that stops leaks and root intrusion. 800/265-0863; www.liquiforce.com.
