Chemical Grouts
Avanti International AV-202 Multigrout
AV-202 Multigrout from Avanti International is a hydrophilic injection grout engineered for long-term infiltration control and soil stabilization. Its high-viscosity chemistry helps the grout stay in place during injection — often used in combination with oakum — allowing it to effectively seal active leaks in cracks, joints and penetrations. It offers exceptional versatility and can be used at ratios from 1-1 to 10-1, providing moderate expansion and superior adhesion to create a durable seal. Once cured, it forms a resilient, rubber-like flexible foam that accommodates moving cracks and joints while maintaining a long-lasting seal. It is NSF/ANSI/CAN 61 certified for Drinking Water System Components, making it a dependable solution where performance and regulatory compliance are critical. 800-877-2570; www.avantigrout.com
CUES Easy Grout
The Easy Grout graphical user interface from CUES leads the user intuitively through the grouting process. The computerized grout control system is designed to consolidate all the valves, electrical controls, etc., into an instrumentation cabinet that can be mounted in any location. The system and user interface includes help files and tool tip descriptions to assist new users and refresh users who have been away from operating for some time. Automated entry logic provides recommended settings for the grouting process automatically based on the basic inputs of pipe size, depth, etc. Because the grout panel is now a computer user interface, it is no longer physically tied to the grout process equipment and can be located virtually anywhere a computer connection, wired or wireless, can be made. 800-327-7791; www.cuesinc.com

The chimney seal has a 50-year design life and is available in four widths, allowing complete chimney coverage up to 24 vertical inches with a single seal. 800-345-3764; www.cretexseals.com
Manhole Odor Eliminator MOE
The MOE from Manhole Odor Eliminator is a passive odor control device designed to mitigate hydrogen sulfide and other sewer gases at the point of release. Installed beneath standard manhole covers, the system incorporates activated carbon filtration and a variable‑volume bladder that responds to pressure fluctuations within the sewer system. By buffering pressure changes and treating intermittent peak gas releases rather than continuous airflow, the device is intended to extend media life and reduce routine maintenance demands. This approach allows odor control to occur locally without the need for active ventilation or chemical dosing. Because the system operates without electricity, fans or external power sources, it can be applied in locations where centralized or powered odor control infrastructure is impractical. Installation and cartridge replacement can be completed using standard tools, supporting routine maintenance activities with minimal surface disruption. 209-545-1663; www.manholeodoreliminator.com

Front jets thoroughly clean any grease, sludge or mud at the bottom. 844-285-5770; www.usb-usa.com
Safety Equipment
LightRing
Safe access during jetting and inspection operations starts with reliable visibility at the point of entry. LightRing delivers powerful, hands-free illumination directly at the manhole opening, giving crews the clear sightlines they need to work confidently during rehabilitation, cleaning and CCTV inspections without juggling handheld lighting. Lightweight and easy to deploy, it enhances operator safety by covering the manhole, containing spray and mist generated during jetting. The system also serves as a physical barrier to prevent accidental falls into an open structure and keep tools from being dropped in or lost during service. During cold-weather inspections, it helps limit temperature variance by reducing cold air intrusion, minimizing camera lens fogging and keeping inspections on track. By improving visibility, control and operator protection, departments may qualify for available workplace safety grant funding. 515-290-8295; www.lightringinc.com
So Safe Equipment Power Lifter
Manual manhole cover removal remains one of the most injury-prone tasks in municipal and utility operations. The Power Lifter from So Safe Equipment replaces manual lifting with a controlled, mechanical solution designed to reduce back strain, pinch-point injuries and lost-time incidents in the field. Lightweight and easy to operate, the tool mounts quickly to jetters, CCTV trucks, combo units or virtually any service vehicle using a standard 2-inch receiver hitch, bringing safer lifting capability directly to the point of work without additional setup or transport equipment. The system is powered by a rechargeable Milwaukee or DeWalt battery platform, eliminating the need for dedicated power sources and simplifying fleet integration. By minimizing physical strain on operators, departments may qualify for available workplace safety grant funding. In addition to injury prevention benefits, many crews report up to two times productivity gains compared to traditional manual lifting methods. 844-767-2334; www.shopsosafe.com
