THE BAUTEX BLOCK

INSULATING CONCRETE FORM (ICF)

The Bautex Block is a composite insulating concrete form (ICF) that makes design simpler, construction faster, and buildings perform better. The blocks are large elements that are lightweight and easy to install by a single person. The blocks serve as forms for building a steel-reinforced concrete wall where the blocks stay in place after the concrete is installed to provide enclosure and insulation for the building.

Bautex Block has been fully tested and is recognized by international building codes. Today, the blocks are manufactured in a fully automated and high production facility in Central Texas utilizing an innovative patented process.

HIGH-PERFORMANCE MATERIALS

The basic material technology used in the Bautex Block is over 60 years old, and has been used extensively in Europe and Asia. The concept was to create a lightweight concrete mixture that would be durable and highly insulating. The Bautex composite material is simply regular concrete (Portland cement, sand, rock, and water) where the sand and rock have been replaced by expanded polystyrene (EPS).

The benefits of the composite material are clear. EPS is lightweight and highly insulating. Portland cement is durable and fire resistant. The Bautex EPS-Cement composite material is lightweight, insulating, fire-resistant, sound reducing, and immune to mold, mildew and decay.

The result is a durable and lightweight block that make construction fast and simple while providing tremendous performance benefits to our built infrastructure.
