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.

Chemical Grouts

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.

Prime Resins PR10

PR10 acrylamide from Prime Resins is a low-viscosity permeation chemical grout that is injected from within the manhole, wicking into the soil outside or used to curtain-grout the exterior. A high-pressure pump injects grout through the manhole wall into the surrounding soil or is injected directly into the surrounding soil, creating an impermeable barrier. The permeation grout doesn’t expand, but rather saturates the soil immediately outside of the manhole (with a desired gel time) that permanently stabilizes the soil and prevents further groundwater penetration. 800-321-7212; www.primeresins.com.

Sealant

Cretex Specialty Products LSS Internal Manhole Chimney Seal

The LSS Internal Manhole Chimney Seal from Cretex Specialty Products is a mechanical seal installed on the frame and grade ring sections of sanitary sewer manholes. These seals eliminate and prevent manhole frame-chimney inflow. During wet weather and snowmelt, clearwater enters manholes through deteriorated or broken frame-chimney joints. This deterioration can be caused by frost heave, soil movement, traffic loading, thermal expansion and contraction of the surrounding pavement, and poor or antiquated construction methods. Each seal is made up of an EPDM sleeve and type 304 stainless steel expansion bands, and it can be easily removed and reinstalled to allow for future manhole adjustments. It has a 50-year design life and is available in four widths, allowing complete chimney coverage of up to 24 vertical inches with a single seal. 800-345-3764; www.cretexseals.com.
