Finished upper 1/3 of the soon to be 16'-10" high stadium retaining wall.
This new "concrete face" is covering that 1/4" wire mesh, 1/2" rebar and the 25' long "soil-nails".
After grading down to the "2nd terrace platform", another row of 25' long "soil-nails" is drilled every 6'.
Besides the drill bit drilling, high pressure air is shot through the hollow drill shaft/bit to help clean out the new 25' long, 6" diameter shaft.
