Precast concrete walls come in various designs and include various uses. Units can be made of precast or prestressed elements, and how they are installed and built will generally be determined by the goals they make.
The simplest form of concrete walls will be a prestressed or precast concrete panel (Also known as “ แผ่นคอนกรีตอัดแรงหรือคอนกรีตสำเร็จรูป “ in the Thai Language) placed between steel support.
In this scenario, the prestress panel will appear far more effective than the simple prepatic panel (because of the strength obtained during the prestressing process).

If the wall is designed to maintain, the panel will usually be 150mm or more, and can reach up to 6000mm among steel. Depending on what pressure is placed on the wall, it will determine; steel type, the foundation required, panel thickness, and the span between steel.
Depending on the design, these units can be used for various applications and wall specialists can be made to offer retention of up to 6000 mm and higher.
Precast concrete blocks offer a variety of solutions to build concrete walls. The interrelated unit allows the ‘gravitational’ retention wall to be built. There are many different units in the market but the basic principle is that the unit is locked together and the mass of the combined unit gives the wall its retaining ability.
