APM SpinCaster
For cities with sufficient manpower, the City Self-Install Program for sanitary and storm manholes and catch basins is a dollar-saving choice. Factory training and the bidirectional SpinCaster from APM enable a three-person city crew to reinforce, seal and protect four to eight structures per day. Supervisors schedule crews as they are available on a day-to-day basis, and cities typically save $250,000 or more by doing 100 to 500 structures during the season. The system includes a pneumatic, spark-free, explosion-proof motor. The bidirectional rotation ensures and even application even with the rotation of 3,500 rpm to maximize radial impingement of mortar to the substrate. The high rpm speed keeps the unit centered in the structure and applies material at the best design thickness calculated for the diameter, depth and conditions of the existing pipe. 515-276-9610; www.waterlinerenewal.com/apm
HammerHead Trenchless HydroBurst 100XTR
The HydroBurst 100XTR from HammerHead Trenchless gives operators the ability to take on a wide range of sewer, water and gas line replacement jobs with just one machine. The unit’s 100-ton capability is rated for up to 16 inches in diameter, yet it is compact enough for use on pipe down to 4 inches. It comes with an easy-to-learn, easy-to-use radio remote control. Freeing operators from the pit allows them to position themselves for the best view of a bursting operation and increases workspace in the pit for rod handlers. Its lightweight, heat-treated alloy rods feature an API-style joint that resists buckling under the greater thrust loads required by longer burst runs, sweeping bends and encrusted and collapsed lines. Used in combination with specialized tooling, operators can burst the toughest steel and ductile steel pipes. 800-331-6653; www.hammerheadtrenchless.com
Perma-Liner Industries Perma-Main Top Gun
The Perma-Main Top Gun from Perma-Liner Industries is a manhole-to-manhole, continuous inversion lining system. It is specifically designed to rehabilitate 8- to 24-inch-diameter pipelines in only a few hours with no excavation or disruption in substrate. The liner is air-inverted through existing manholes and steam cured in as little as 90 minutes using compact 750,000 Btu dry steam generators. This minimizes repair time, road closures and reconstruction, and allows for safe reactivation of the repaired pipeline in just hours. Because the system can be continuously fed, there is no limit to the length of material it can invert. Depending on the infrastructure, the installation lengths for liners typically average 300 to more than 600 feet. Prep time is minimal because all liner materials are premeasured and delivered to the repair location pre-saturated. 866-336-2568; www.perma-liner.com
Chemical Grout
Avanti International injection grouts
Infiltration enters underground systems every day through defects or faulty joints in manholes, causing system capacity issues, overload at treatment plants and possible injury to the community. Avanti International injection grouts have historically proven to be an economic and long-term solution to combatting infiltration entering all areas of a collections system, including manholes. Injection grouts are engineered to stop leaks, stabilize soil and control groundwater, and be used in precast barrel joints, brick and concrete masonry units, pipe penetrations, vertical or horizontal cracks, void fill and pinholes. Each technique enables the technician to stop several leaks at once and helps to extend the life of the structure. 800-877-2570; www.avantigrout.com

Insert
Simple Solutions Distributing Wolverine Brand Manhole Odor Filter Insert
Hydrogen sulfide-based sewer odors emanating from manhole covers are an extreme nuisance for residential homeowners or users of nearby public facilities. Simple Solutions Distributing offers the Wolverine Brand Manhole Odor Filter Insert to combat the issue. Made with durable and corrosion-free high-density polyethylene copolymer, each odor insert is made to order based on specific manhole measurements. The insert sits flush on the rim so it won’t interfere with the installation or removal of the manhole cover. They install easily with no tools necessary. Each insert comes with the initial 20 pounds of Norit Darco’s H2S Sulforsorb activated carbon, and its H2S breakthrough indicator to let the user know when maintenance is required. The insert requires no routine maintenance other than occasional replacement of the carbon, which is easily replaced and does not require removal of the insert from the manhole. 866-667-8465; www.industrialodorcontrol.com
Manhole Liners
AGRU America Monoform PLUS
Monoform PLUS from AGRU America is a manhole and wet well rehabilitation solution that combines HK Solution’s Monoform technology with AGRU-ULTRA GRIP. The technology comprises a concrete forming system installed within existing manhole structures. Inner forms wrapped with ULTRA GRIP pair with the existing structure, which serves as the outer form. Concrete is then poured between the two forms to create a new structure. The concrete cures around the anchors, making the liner mechanically bonded permanently into the structural frame. The solid construction meets the Cooper E-80 locomotive load testing criteria. It offers equal performance and design life compared with a typical replacement job, with the benefit of minimal traffic disruption, cost-effectiveness, faster installation, no required external bypass pumps, and no compaction issues. Finish most sites in two days without being taken out of service. 843-546-0600, www.agruamerica.com
Epoxytec CPP Sprayliner MH
CPP Sprayliner MH from Epoxytec is designed to rehabilitate sanitary sewer collections system assets and other underground, cylindrical and/or small box structures in contact with hydrogen sulfide and in need of I&I mitigation with sealed lining. It performs in areas subject to chemical attack and, as a seal preventing oxidation while holding back water migration, I&I and hydrostatic pressure. The material can be sprayed ultra-high-build, up to 1/4 inch per pass. Blended with reinforcing agents and various fibers, the material when cured creates reinforcement lining as a fiber-reinforced polymer, with high-strength and flexural properties for partially or fully deteriorated structures. 877-463-7699; www.epoxytec.com
Sprayroq SprayWall
SprayWall from Sprayroq is a rigid polyurethane material that provides structural integrity and infiltration control to underground infrastructure assets. It is a 2-1-ratio product that is applied via a heated, plural component spray system. It begins to gel in about eight seconds and is tack-free after two minutes. Within 30 to 60 minutes, the initial cure is complete and the structure is capable of accepting flow. The benefits include its structural capacity, which provides for protection against multiple load components within an underground asset including water, soil and traffic loads. In addition, it allows an asset owner to return a structure to service quickly, creating a huge savings on bypass cost, as well as decreasing the overall downtime for a given structure. It is also third-party tested and most recently has undergone significant successful evaluations through AASHTO. 205-957-0020; www.sprayroq.com
The Strong Company Strong-Seal System
Strong-Seal MS-2A and MS-2C from The Strong Company are designed to rehabilitate municipal concrete and masonry structures, and effectively stop inflow, infiltration and exfiltration. When spray-applied to a minimum of a 1/2-inch thickness, the cementitious mortars are impervious monolithic liners with compressive and flexural strengths exceeding that of the original structure. Made with Portland cement, MS-2A is the most cost-effective solution for stopping infiltration and restoring structural integrity. MS-2C provides high early strengths and added corrosion protection in mild sulfide environments. High Performance Mix is a pure-fused calcium aluminate mortar that stops infiltration, restores structural integrity and protects against microbiologically induced corrosion in sanitary sewer systems with harsh sulfide conditions. 800-982-8009; www.strongseal.com
