Modular Block Wall With Geogrid Into Bedrock

[JohnTerry4]

I am designing a Mechnically Stabilized Earth Wall Using modular blocks and geogrid reinforcement. Bedrock may be encountered during excavation for the geogrid which would hinder from achieving the required geogrid embedment lengths during construction.

Is there a recommended way to anchor the geogrid into the bedrock (it is sound, igneous bedrock) in lieu of chipping bedrock to achieve the required geogrid length? Does anyone have a detail to share?

A dimension diagram, giving a section above and below the wall, with notes regarding geology and existing/worse case groundwater is required.
