Drizoro - fast-setting repair mortar PCC low-shrink Maxmorter F

Maxmorter F is a one-component mortar containing microsilica which, when mixed with water, produces a fast-setting repair mortar with high mechanical parameters. It is intended for filling cavities in concrete. It is a mortar with low shrinkage and very good adhesion to concrete and steel. The product is available in a basic version and in a variant with reduced technical parameters Maxmorter F / 1.
