Design Information

Ground Retaining Wall Design 

The table below gives the maximum effective wall heights for the different precast concrete panel types available based on the anticipated profile and additional surcharged loading and, in the case of horizontal panels, the span between support columns. 

 Assuming 1800kg/m backfill material with 30 deg internal angle shear resistance and free draining in all cases.
