When Minas de Aguas Tenidas, S.A.U. (MATSA), needed domes to cover their crushed ore stockpiles in Andalucía, Spain, they turned to Geometrica.
When Barrick's Zaldivar mine needed a 95m dome to cover its ore stockpile, it selected Geometrica for several reasons: First, it had considerable experience with these types of domes in Chile (Mantos Blancos, Escondida, Pucobre, and others). Second, the Geometrica offered a lower lifetime price than competitive structures. Third, the installation program was fast even while the stockpile remained in operation.
One hundred meters. It's a nice round number, about the length of a football field. Or one thousandth the distance to space. And a heck of a long way for any roof to span without columns.
Geometrica domes provide the most efficient cover for a limestone blending bed because they are lightweight and can span large areas without intermediate supports.
Environmentally-responsible mines use domes to prevent and control dust emissions.
Geometrica's efforts in Aviary constructions have been documented in an article that goes beyond our website content and shows the wonderful applications of our structures for this purpose.
