Video: How It All Starts

Construction of any Geometrica dome or space frame is safe, easy and quick.

Here's a short video that shows how it all begins with our patented cylindrical hub and galvanized steel tubes that are coined and grooved at the ends.

Case Study: Cuajone Expansion, Peru

The Cuajone mine, located in the rugged Peruvian Andes, is the largest single copper mine and smelter complex ever built. The 4,144-square-kilometer mining triangle begins high in the Andes with a water supply at Lake Suche and ends with a smelter on the Southern Pacific coast. Covering the copper ore was part of Southern Peru’s overall initiative to reduce operating and maintenance costs as well as the environmental impact of the Cuajone mine. Geometrica's solution? Design of a 120m long, super-structure that combines three structure types - an arch vault, semi-dome and end wall.

Cladding Options

Our domes can accommodate many types of cladding designed to fit both purpose and budget. For this coal storage dome in Chile, cladding is made of galvanized and painted corrugated steel panels combined with translucent acrylic panels.

Big & Tall

At certain sites, covering large spans without any internal columns is a very tall order.

One example, the mega-tall dome at the Caserones copper mine in Chile. At 94m (308 ft) tall, it feels right at home among the peaks of the Andes. The dome is so tall that if it sprung from her island, Lady Liberty couldn't touch the apex with her torch! The dome was designed so that it would shed incredible amounts of snow. At 4000 meters (13,000 feet) above sea level, ground snow exceeds 8kPa (165 psf).

The Essential Tool

From drilling machines to excavators, crushing and grinding equipment - the mining industry depends upon having all the right tools.  Each type of mining activity comes with its own set of tools.  Perhaps the most visible activities, and certainly among the most controversial, are ore crushing and stockpiling. The tools for these activities are conveyors, crushers, and, crucially (pun aside), domes. Domes improve a mine's environmental compliance - and its local image.

ISO 9001:2015 Certified!

Geometrica recently achieved the latest ISO 9001:2015 certification for the design, manufacturing and installation of reticular structures and domes. The company previously earned certification under ISO 9001:2008 and has been audited and registered annually by BSI since 2008. We are hugely proud of this achievement and would like to thank the entire team at Geometrica and BSI for their involvement. We couldn’t have done it without you!
