Architectural Precast

Architectural Precast

Precast is a minimum 4" thick concrete panel system that looks like many natural stones and granites by exposing the beautiful aggregates within the mix designs.

Panel Description

Architectural precast consists of a solid concrete panel that typically has a 4" minimum thickness. This overall thickness may need to be increased depending on these factors.

  • The section shape of panel has deep returns, deep reveals or protruding bullnose features.
  • Designer chooses to adhere natural or manmade materials to the face of panel. (ie. Thin Brick, Granite, Limestone, or Tile)
  • Additional structural strength needed due to: longer spans between connection points, to take on additional external loads such as auto impact in parking garages, or blast loading, etc.

A 4" thick panel weighs approximately 55 pounds per square foot of surface area. This weight may considerably affect the design and overall cost of the structure and the prewelded items necessary for the attachment of panels.

The maximum panel size is determined by material properties, project requirements and shipping limits.


Architectural Design Capabilities

There are few limits to the sections, shapes and finishes that can be produced with architectural precast concrete. The mix design of architectural precast concrete typically consists of: white cement; ½" to ¾" aggregate; sand; and a color additive to achieve the Designers desired look. There are few limits to the colors that the Designer can choose from and all of our designs are custom made for each individual project. Architectural precast concrete gives the designer the option to choose between a light or heavy sandblasted finish. A heavier sand blast will expose the aggregate in the mix and can produce a different color/texture affect. Architectural precast concrete also gives the option to adhere different natural and manmade materials to the face (Granite, 1 1/8"; Limestones, 1 1/8" to 2"; Brick, ½" to 1"; and Tile, approx. 5/16"). The overall thickness of the panel will typically be 4" plus the thickness of face material.
