The Bau­tex Block wall is a screen-grid insulated concrete wall forming (ICF) system that cre­ates a grid of close­ly spaced ver­ti­cal and hor­i­zon­tal con­crete mem­bers with­in a con­tin­u­ous­ly insu­lat­ed wall. While the Bau­tex Block itself is not a load-bear­ing ele­ment of the sys­tem, the screen-grid con­crete struc­ture with­in the wall is the pri­ma­ry load-bear­ing exte­ri­or wall assem­bly for many projects.

In oth­er cas­es, Bau­tex can be used as a sec­ondary struc­tur­al sys­tem or build­ing enve­lope solu­tion in con­junc­tion with anoth­er struc­tur­al sys­tem such as struc­tur­al steel and poured con­crete frames.

How are Bautex Walls Designed?

The struc­tur­al design of any build­ing uti­liz­ing the Bau­tex Block Wall Sys­tem must always be com­plet­ed by a struc­tur­al engi­neer licensed in the state where the project will be locat­ed. There are two pri­ma­ry meth­ods to deter­mine the struc­tur­al design para­me­ters for a project:

Prescriptive Design (Theoretical Method):
The pre­scrip­tive design method uses gen­er­al­ly accept­ed engi­neer­ing prac­tices, such as slen­der col­umn the­o­ries in ACI 318, to cal­cu­late the design of the con­crete ele­ments with­in the Bau­tex Block walls.

Hybrid Design (3D Modeling Method):
The hybrid design method uses gen­er­al­ly accept­ed engi­neer­ing prac­tices and 3D mod­el­ing soft­ware to indi­vid­u­al­ly ana­lyze and design Bau­tex Block walls. The 3D mod­el­ing method allows the engi­neer to account for project spe­cif­ic details and to ana­lyze the inter­ac­tion between dif­fer­ent ele­ments. Using an under­stand­ing of the inter­ac­tion of dif­fer­ent ele­ments, includ­ing jambs, pilasters and per­pen­dic­u­lar walls, the 3D mod­el­ing method allows designs that are not pro­vid­ed for in the pre­scrip­tive design tables.

Bautex Blocks form a continuous grid of concrete beams and columns that are 6-inches in dimeter on 16-inch centers throughout the wall. This profile is more efficient, using half the concrete of conventional 6-inch walls but yields more than 70% of the strength.
Beams are formed in the Bautex Block wall where a floor or roof connection needs to be made. Bond beams are also used at an intermediate height on taller walls where the concrete needs to be split into multiple pours.
Similar to other structural systems, openings will normally require larger jambs and lintel beams to be formed in the Bautex Block wall in order to carry the loads. Openings as wide as 18-feet can be achieved using the concrete within the Bautex walls.
Integral concrete pilasters formed within the Bautex Block wall can be used to carry specific point loads or to provide additional flexural capacity on taller walls. The most efficient profile is an 8-inch pilaster, which has significant capacity while remaining entirely within the thickness of the Bautex wall and does not interrupt the continuous insulation.

Bau­tex pro­vides Struc­tur­al Engi­neers of Record all the design tools and tech­ni­cal sup­port required to quick­ly and effi­cient­ly design walls using the Bau­tex Wall Sys­tem. In some cas­es, how­ev­er, engi­neers may elect to del­e­gate the design of the Bau­tex walls for a project to third-par­ty engi­neers. Bau­tex has devel­oped rela­tion­ships with a net­work of engi­neer­ing firms that will pro­vide these ser­vices for a vari­ety of build­ing types, includ­ing projects that require wind­storm engi­neer­ing.
