typically, precast concrete wall systems fall into three basic categories: solid, sandwich and thin-shell. these can be panelized and erected in either a horizontal or vertical position and used on all types of structures, from residential to commercial, institutional to industrial. wall panels can be designed as non-loadbearing or loadbearing

thin-wall. thin-wall is a structural load bearing, precast sandwich wall building envelope system that features composite action between concrete wythes. the system enables a very energy efficient building with edge-to-edge eps or xps insulation without thermal bridges and uses less concrete than traditional structural wall panels.
despite readily available technology and all of the advantages mentioned in this article, the tilt-up industry has been slow to embrace the approach. the plant precast wall producers have actively been advancing connector technology and delivering composite wall panels for the last 10 to 20 years, though they have not always been ideal.
