This contractor dual-component FLEXKIT-1300 includes all you need to repair dry, wet, or actively leaking cracks, joints, and various voids in below-grade foundations and concrete structures. It permanently and immediately prevents and stops actively leaking cracks, then quickly expands and cures to form a flexible gasket in the voids. It then creates a compression seal that remains flexible.

FLEX-1300 is a dual component, low-range viscosity, high-quality crack repair resin designed explicitly for floor cracks between 3/32" to 1/2" wide, and can be used with either gravity feed or injection method.

We purchased this product to seal a large crack between our concrete slab and the exterior wall. We filled the crack with sand and then applied the Flexomeric. It worked great! Easy to use and very little smell. We were very pleased with the results.
