Chemical Grouts

Avanti International AV-100

AV-100 chemical grout from Avanti International is used to rehabilitate storm and sanitary sewer systems by eliminating infiltration in manholes, mainlines, joints, laterals and lateral connections before or after various forms of CIPP lining. It is injected after lining seals in the annular space between host pipe and liner, and lateral reinstatement, which are the primary sources of infiltration. It is an ultra-low viscosity, chemically reactive gel with a similar viscosity to water. It can permeate anywhere water can travel and has adjustable cure times from seconds to hours, creating an effective, long-lasting water barrier while providing soil stabilization. 800-877-2570; www.avantigrout.com

Prime Resins SoiLok MH

SoiLok MH from Prime Resins is an extremely thin two-component liquid resin designed specifically for manhole applications. It is a soil binding system (a subterranean grout) used to stabilize and bind loose soil or sand, stop underground water flows and seal weeping leaks in manholes and other below-grade structures. It is an easy-to-use premeasured kit, resulting in predictable set times in noncohesive soils. It has super-low viscosity, nearly as thin as water, allowing for thorough permeation. It contains no suspended solids in the blended product, which means no airborne particulates. It has adjustable gel set times for various site conditions. Achievable compressive strengths are site specific and strongly dependent on sand/soil conditions, composition and particle size distribution. 800-321-7212; www.primeresins.com

Manhole Liner

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. 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

Manhole Parts and Components

CCI Piping Systems WrapidSeal Manhole Encapsulation System

The WrapidSeal Manhole Encapsulation System from CCI Piping Systems consists of an engineered primer and a wraparound, heat-shrinkable sleeve designed to seal joints and prevent groundwater from entering a collections system. This material has a high-shrink membrane (70% stretch and 40% recovery) designed to shrink around any manhole profile. In addition, the high-tensile strength accommodates structural movement while the tough backing resists soil stress and provides suitable abrasion resistance. It can be used for new construction or for the rehabilitation of existing manholes to control infiltration through joints and prevent deterioration, thus eliminating costly maintenance repairs and the added expense of treating groundwater. 800-867-2772; www.wrapidseal.com

Cretex Specialty Products Internal Chimney Seal

Cretex Specialty Products Internal Chimney Seals are mechanical, so there is no need to worry about surface adhesion or stopping active leaks prior to installation. The seals eliminate and prevent manhole chimney inflow. During wet weather, clear water enters the manhole through deteriorated and broken chimney joints, which may burden the collections system. 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

Mr. Manhole Cookie Cutter System

The Mr. Manhole Cookie Cutter System involves drilling a small hole above the utility, using the cutter to remove a 74-inch round asphalt or concrete piece of pavement. This keeps workers 56% below OSHA limits. The removed “cookie” is then lifted out, and a protective cage is placed for vacuum excavating. This method exposes the utility for repair while preserving the road base. The result is a smooth, clean repair aligning with the road’s original design. This approach revolutionizes road and utility repairs, making the process quicker and more efficient. 833-242-2221; www.mrmanhole.com

Sealant

The Strong Company Strong-Seal System

The Strong-Seal System from The Strong Company offers a variety of cost-effective engineered cementitious products designed to rehabilitate municipal concrete and masonry structures and effectively stop inflow, infiltration and exfiltration. When spray-applied to a minimum of 1/2-inch thickness, the cementitious mortars are an impervious monolithic liner with compressive and flexural strengths exceeding that of the original structure. Both MS-2A and MS-2C are fiber-reinforced spray-applied cementitious mortars. 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 (pH of 1.0 or greater). 800-982-8009; www.strongseal.com
