Since the beginning of mankind, aggregates were present directly and indirectly in almost all development achievements of our society. Civil works such as roads, airports, schools, hospitals, among others would not be possible without them.

Our aggregate division produces unbound granular structural materials as well as aggregates for concrete and asphalt, building materials of essential importance in the construction of civil works on Chiloé Island.

Also special rock aggregates are made to order, for which we count on the support of Najar Ingenieros S.A., whose professionals have extensive technical expertise for consultancy in the design and production of special aggregates.
