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.



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mate­r­i­al is sim­ply reg­u­lar con­crete (Port­land cement, sand, rock, and water) where the sand and rock have been replaced by expand­ed poly­styrene (EPS).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.
