Non-shrink grouts (NSG)

Non-shrink grouts are used to fill gaps, voids, and anchoring applications. Unlike traditional cement-based grouts, non-shrink grouts are specifically formulated to minimize volume change during the curing process, ensuring that they do not shrink or crack as they harden.

Special grouts for wind turbines

Non-shrink grouts are typically composed of a blend of cement, fine aggregates, BASF additives and water. The materials work together to create a stable and dense mixture that can be easily poured or pumped into the desired area.

Non-shrink grouts are commonly used in structural applications where load transfer, stability, and durability are critical. Wind turbine grouts are a good example.
