Strength and Design in Concrete Forms

There is something amazingly raw and beautiful in cast concrete forms and buildings. These forms can become any shape imaginable and all that is required is the form to hold the concrete as it dries. Panels of remarkable sizes can be placed on site in construction zones, allowing buildings to rise in record breaking time […]

Bacardi Enhances The Efficiency Of Its Rum Facility

Bacardi, a wine company based in Puerto Rico, has been building its reputation for sustainability since 2006. Last year, it announced that it significantly reduced its water and energy usage. It is now taking the next step towards sustainability with the installation of solar skylights, which are intelligently designed ‘windows’ that allow plenty of sunlight into […]
