- Strong-Seal® MS-2®A 60 lb. bag is a cost-effective, fiber-reinforced, spray-applied cementitious mortar designed to stop infiltration and restore structural integrity in concrete and masonry structures. Engineered to create a durable, impervious monolithic liner, MS-2®A fills all voids and achieves a mechanical and chemical bond to the existing substrate. When applied to a minimum 1/2-inch thickness, this product forms a robust protective layer with compressive and flexural strengths that exceed those of the original structure. Compared to its counterpart, MS-2®C, which offers higher early strengths and added protection in mild hydrogen sulfide environments, MS-2®A is the ideal solution for projects focused on cost efficiency and long-term structural rehabilitation. Both products are designed to handle a wide range of infrastructure repairs, including manholes, pipelines, tanks, and tunnels, providing lasting protection and performance in even the most demanding conditions.
- Versatile Application: Adaptable to vertical, horizontal, and overhead repairs
- Infiltration Prevention: Effectively stops inflow and infiltration, providing a robust liner to prevent leaks and groundwater intrusion
- Zero Shrinkage: Maintains dimensional stability with no shrinkage (ASTM C596) at 28 days
