Socketed Foundations on Slope

State WI
Description Text

Cable barrier installations are often placed on cross-slopes, typically 6:1 and potentially 4:1 slopes.  When installing socketed foundations for the posts on these slopes, the back side of the foundations often protrude a few inches above the ground line.  Under the right conditions, this protrusion  could result in a violation of the 4" maximum stub height established by AASHTO and the RDG. Is there a way to address this issue?

To minimize the extent of the foundation protruding above ground line, it is recommended that the foundation be installed with the center of the foundation (top) be installed level with the surrounding terrain, as shown in the attached sketch.  This position also ensures the post and cables are installed at the correct height relative to ground line.
