What Are Precast Concrete Walls

Precast concrete wall systems can consist of a variety of shapes and wall types. Typically, precast concrete wall systems fall into three basic categories: solid, sandwiches, and thin shells. These devices can be mounted on horizontal or vertical facades and used for various types of buildings, from residential to commercial, institutional to industrial. Wallboards can be designed to be non-weight bearing or load-bearing, bearing floor and roof loads as well as lateral loads.


Solid walls

Solid wall panels refer to walls made of solid concrete, rather than including integral insulation. These wall systems require some form of insulation and interior wall/finishing systems to complete the building envelope.


Typical width: 4 to 15 feet.

Typical height: 10 to 50 feet.

Typical thickness: 4 to 12 inches

Surface treatment: Since the wall panel is cast in a planar manner, the template side is usually the one that will be exposed in the field of view in the final configuration. This face can be made with almost any type of topcoat. The back is usually smooth or may have a light broom finish.


Sandwich wall

Insulated sandwich panels can be rigid constructions, rigid structures, or a combination of both. The difference between typical panels and insulated sandwich panels is that the latter is cast between two or more layers of concrete with a rigid insulator. The insulation thickness can be varied to produce the desired insulation performance ("R" value).


Structural behavior is:

Thin shell wall shell finished product

In this composite material, these whips are connected using a connection by completely transferring the load of the insulator. Structural performance is based on the entire thickness of the panel; either

Non-composite materials, in which the whips are connected by insulating layers, limit the performance to each individual volume.

Whether the panel is composite or non-composite depends on the configuration and material of the binding. Insulated sandwich panels can be designed to support and support floor and roof components. They make ideal structural elements for this purpose, usually by casting a thicker interior to provide the necessary support. They also can not undertake to complete a façade.


Typical width: 4 to 15 feet.

Typical height: 8 to 50 feet

Typical thickness: 5 to 12 inches including 1 to 4 inches of insulation

Surface treatment: Like a typical wall panel, the panel is cast in a plane, so the side of the panel is usually the side that can be seen in the final construction. This face can be made of any type of topcoat. The back is usually smooth or may have a light broom finish. Indoors usually do not require additional battens and drywall to create a finished surface
