Sika has opened a new production facility in Ust-Kamenogorsk with production lines for mortar and concrete admixtures, as well as a modern laboratory. The plant is Sika’s fourth factory in Kazakhstan and is located in a key industrial region in the eastern part of the country. As a leader in construction chemicals, Sika is also involved in large-scale projects in Kazakhstan, a fast-growing market.

With the opening of the new plant in Quito, Sika further strengthens its presence and proximity to customers in Ecuador. This strategic investment enhances Sika’s ability to tap into Ecuador’s full market potential for its mortar solutions, which will be primarily used for interior walls and tile adhesives.
