By integrating concrete rigid protective fences and L-shaped retaining walls, we achieve a significant reduction in construction time.
The "RPCA-AD Wall" is a precast rigid protective fence retaining wall that eliminates the need for dangerous tasks such as rebar assembly and formwork installation at heights, thereby improving safety on site. There are two types available: a 250mm thick type and a 300mm thick type that allows for the installation of sound barriers and other structures.
