Cement-based grouts

The highly fluid Fortegrout is intended for filling in holes, grouting equipment and anchoring components into concrete slabs, where a high level of adhesion to the base concrete is required.

The product can be applied to seasoned substrates and its fast accumulation of firmness makes it possible to use it for work that requires minimal technical pauses.

Use Fortegrout for grouting bearing cases and anchoring plates, filling in large joints and cavities, or for reinforcement.

Special features of the product

Anti-Shrinkage Agent

The ASA additive chemically modifies the course of the hydration reaction and compensates for the shrinkage of the concrete mix during setting and hardening time. The use of these additives provides a higher volume stability, which fills in and fixates the space securely. A better shrinkage curve is achieved this way over a longer time span.


Thanks to the SILICA EFFECT, the use of very fine spherical particles in the dry component of the system helps to achieve a lower porosity and consequently lower seepage, increases frost and corrosion resistance, further increases the physical and mechanical properties (compressive and flexural strength and abrasion resistance) and provides higher compactness.
