The project has two MagnumStone walls: a gravity wall with a maximum exposed height of 5’ and a geogrid reinforced wall with a maximum exposed height of 20’. A total of 6,190 SF of wall area was installed. The specification of MagnumStone was driven by the need for the short wall by the track to be a gravity system. There are numerous utilities behind the wall and the engineer did not want geogrid reinforcing to be used. Also, the smooth surface of the precast blocks provides a less abrasive surface in an area where there is interaction with atheletes and spectators. The tall wall utilized geogrid reinforcing and was only done in MagnumStone in order to match the other wall.
