Concrete is mixed at a plant . . .
. . . and transported to the site of the pour.
Slide8Green Concrete?LEED® credits earned forUsing aggregate extracted, processed, and manufactured within a 100-mile radius of the project site Using fly ash, slag, and recycled aggregate Improved energy efficiency by taking advantage of thermal mass of concreteReduced VOCs using concrete compared to other construction materialsGenerating less construction waste than wood or steel

Slide13Tilt-up ConcreteConcrete wall sections (with reinforcing) are poured horizontally on site, tilted vertically, and then anchored.

Slide14Tilt-up ConcreteCan be formed into a variety of shapes and sizesDifferent surface treatments and form inserts can be used to create a wide variety of surface texturesRelatively quick design and construction time
Form inserts give relief to the panels
Thin bricks are set in the form before the concrete is cast
