When concrete experiences damage and require repairs, non-shrink grout provides an excellent solution. Non-shrink grout is a type of cement-based grout specially formulated not to shrink as it sets. Typically these types of grout mixes require some sort of grout admixture. Fritz-Pak’s NS-7 produces a more uniform non-shrink grout with less water and extended set times.
When NS-7 mixes with water, it starts producing hydrogen gas that causes the mix to expand. The expansion of the gas continues as it sets up, overcoming any shrinkage that might occur within the mix. Additionally, NS-7 increases the flow of the grout mix to ensure that it fills every crevice and leaves behind no voids.
Non-Shrink grout is typically used to repair voids in formwork, ICF structures, and other concrete projects that are prone to experiencing honeycombing. When properly mixed, the grout flows in and fills the void and then hardens to increase the durability of the building project. If there is any shrinkage as the grout dries, it could compromise the integrity of the repair. That is why having a non-shrink grout admixture like NS-7 is so important.
