Repairmörtel

Repairmörtel, also known as repair mortar or patching mortar, is a specialized building material used to fix damage to concrete and masonry structures. It is formulated with a blend of cement, aggregates, and additives that provide specific properties such as rapid setting, high strength, and good adhesion. Unlike standard mortar, repair mortars are designed to withstand the stresses of structural repair and to bond effectively to existing substrates, even in challenging conditions.

The primary function of repairmörtel is to fill cracks, spalls, and other imperfections in concrete surfaces. These repairs can be structural, where the mortar restores load-bearing capacity, or non-structural, focusing on aesthetics and preventing further deterioration. The specific composition of repairmörtel varies depending on its intended application. Some types are designed for shallow repairs, while others are formulated for deep fills or underwater applications. Additives can include polymers to enhance flexibility and bonding, or accelerators to speed up the setting time in cold weather.

When applying repairmörtel, the damaged area must first be properly prepared, which typically involves cleaning, removing loose material, and sometimes roughening the surface to ensure good adhesion. The mortar is then mixed with water or a specific liquid component according to the manufacturer's instructions and applied using trowels, spatulas, or specialized pumping equipment. The cured repairmörtel should seamlessly integrate with the surrounding material, providing a durable and long-lasting solution.
