EXPANDIT® and OPTONIT®
Our additives for renders, mortar & co.
GRIMM Metallpulver GmbH offers a range of functionally effective products for preventing cracks, also in combination with technical improvements and suggestions for formulation and cost optimisation. The elimination of cracks can only be achieved by removing or reducing shrinkage in dry mortar products. Our EXPANDIT® and OPTONIT® products achieve a slight, targeted swelling in the structure and thus reduce the shrinkage.
