Rainstopper LLC products

The Stainless Steel Rainstopper is a patented manhole insert designed to eliminate inflow in your municipality’s sanitary sewer system. It also reduces the infiltration of street level contaminants, while simultaneously controlling the escape of undesirable sewage odor and minimizing traffic related manhole noise and cover displacement. The insert is manufactured in the USA to precise, custom specifications from corrosion resistant 304 or 316 stainless steel. Its unique design allows the venting of sewer gases through a non-mechanical device, reducing maintenance costs by eliminating moving parts. Weighing only 10 pounds, it can be easily installed by a single person.

CMS 10K provides a system for the rehabilitation of concrete or masonry structures to stop infiltration, exfiltration, and restore structural integrity where there is no evidence of hydrogen sulfide (biogenic) corrosion. CMS 10K is a Type I/II portland cement based product blended with pozzolans, masonry sand, alkaline-resistant fiberglass reinforcement, and performance enhancing admixtures. It is used to form a structural monolithic liner covering all interior substrate surfaces. CMS 10K is specifically formulated for applications with a pH of 3.0 or higher.

SG Mastic differentiates itself from all other epoxy systems with its exceptionally low pinhole formation rate (< 1%) and bonding capacity. A 2-component, solvent-free, moisture insensitive epoxy system, SG Mastic’s 100% solid, low-odor amine-cured proprietary formula provides exceptional resistance to most organic and inorganic acids. Specifically designed for the protection of sanitary manholes, wet wells, and valve vaults, it cures in the presence of moisture. Formulated to be mixed on site without the need for proprietary equipment, its paste-like viscosity is designed to withstand sagging at thicknesses up to ¼ inch. SG Mastic is recommended for coating horizontal, vertical, and overhead surfaces.

Rainstopper Ring Seal chimney sealant is a two-component, high performance urethane elastomeric coating specifically designed for high build applications. When fully cured, Ring Seal forms an extremely tough, abrasive-resistant rubber coating that provides protection from surface impact as well as corrosion on metal, wood or concrete. Added UV stabilizers provide additional protection from weather and wear.
