Applicators

1 // Aries Industries test and seal grouting system
The test and seal grouting system from Aries Industries reduces setup time and provides efficient hands-on control to quickly seal leaking joints. Grout — pumped to a leaking joint — flows through the leak, sealing the surrounding soil to form an impenetrable barrier. Sixty-gallon tanks and continuous-duty mixers provide high volume to seal large voids. Reels for fast deployment and retrieval, as well as high-power winches, quickly move the packer from joint to joint for high productivity. The unit’s 800 feet of color-coded hose allows long runs. The truck comes with a bench, storage and room to work. The operator tests and seals the joints while working in the control room, where test data and the sealing process are easily viewed, recorded and logged. 800-234-7205; www.ariesindustries.com

2 // HyFlex Slinger Spincaster
The Slinger Spincaster from HyFlex allows wastewater contractors to coat manholes with spray-applied mortars with much less entry time into the hole itself. A variable-speed electric motor allows smooth speed control of the spinning plate and more torque to evenly apply on very thick mortars. An angled spinning plate with replaceable hardened blades sends the material out evenly, up to a 30-degree angle, allowing material application outward as well as upward, also allowing effective material application under the ring and along the chimney. An electric winch allows it to be moved smoothly and steadily to give a controlled pass every time. An aluminum case construction and nylon slinging cavity allow easy cleanup. 866-849-6246; www.hyflexcorp.com

Chemical Grouts

3 // Avanti International injection grouting
Every manhole is unique. Therefore, there is no one-size-fits-all rehabilitation method, but it begins with a thorough condition assessment. Manholes are vulnerable to defects and a significant contributor to inflow and infiltration in collections systems, leading to excess flow to treatment plants and increased cost to ratepayers. As a stand-alone solution or first step in a multistep process, injection grouting from Avanti International stops active infiltration, stabilizes surrounding soils and fills voids outside the structure. Complementary to cement coating and epoxy lining, injection grouting can be a first defense against infiltration. There are multiple techniques for grouting manholes: for brick manholes, curtain grouting is recommended to create an impermeable barrier and positive seal outside the structure; for precast manholes, spot repair, vertical crack injection and horizontal joint injection are acceptable methods. Injection grouting can be a low-cost/high-reward, long-term solution for extending manhole service life. 800-877-2570; www.avantigrout.com

4 // SpectraShield Liner Systems SpectraGrout
SpectraGrout from SpectraShield Liner Systems is a single component, hydrophilic polyurethane resin designed to repair cracks, seal around pipe penetrations, open joints and to stop leaks in wastewater structures.
