Strong Seal Systems: before and after

The Strong-Seal Systems for Manhole Rehabilitation

The Strong-Seal® System offers a complete family of cost-effective engineered products, specifically designed to rehabilitate municipal concrete and masonry structures and effectively stop inflow, infiltration and exfiltration.

MS-2®A and MS-2®C are fiber-reinforced spray-applied cementitious mortars. The result, when spray-applied to a minimum 1/2” thickness, is an impervious monolithic liner with compressive and flexural strengths exceeding that of the original structure. MS-2®A is the most cost-effective solution for stopping infiltration and restoring structural integrity, while MS-2®C provides high early strengths and added corrosion protection in mild sulfide environments.

Strong-Seal® High Performance Mix is a pure-fused calcium aluminate mortar. This product stops infiltration and restores structural integrity and is specifically designed for protection against microbiologically induced corrosion. As the pH evolves downward, Strong-Seal® High Performance Mix regulates microbial activity, providing maximum corrosion protection, while ordinary portland and silica fume cements exhibit ongoing corrosion.

Strong-Seal® Profile Plus is a calcium aluminate cement-based product used for building back deteriorated substrates to original dimensions to provide a smooth surface for application of an epoxy topcoat.

Strong-Plug® is a rapid-set (60 seconds) hand-applied cementitious product for stopping infiltrating water and making repairs which require high early strength. Strong-Plug® may be applied in a dry form directly to minor infiltration or mixed with water to a thicker consistency for application to more active leaks. Strong-Seal® QSR is a rapid-set (10-15 minutes), high early strength, acid resistant, hand mixed and hand applied, calcium aluminate cement-based product for filling voids and repairing inverts in concrete, brick or other masonry constructed structures.
