Korjauslaasteet

Korjauslaasteet, often translated as repair mortars or patching compounds, are specialized cementitious or polymer-modified materials used to repair damaged concrete or masonry. They are designed to bond well to existing substrates and provide structural integrity and aesthetic restoration. These materials come in various formulations tailored for different repair situations, including horizontal, vertical, and overhead applications.

The primary function of korjauslaasteet is to fill cracks, spalls, and other surface defects. They can be used for both minor cosmetic repairs and more significant structural rehabilitation. The selection of a specific korjauslaaste depends on factors such as the size and depth of the damage, the environmental conditions, the required strength, and the desired setting time. Some formulations are quick-setting, allowing for rapid project completion, while others offer extended working times for larger or more complex repairs.

Common applications for korjauslaasteet include repairing damaged bridge decks, repairing potholes in roads, restoring facade elements, and fixing concrete structures in industrial environments. The performance of these repair mortars is crucial for extending the service life of concrete structures and preventing further deterioration. Proper surface preparation, including cleaning and sometimes roughening the substrate, is essential for achieving optimal adhesion and long-term durability of the repair.
