This sound wall was built using 3D Cementitious sandwich panels, between the motel and a set of railroad tracks. The wall is approximately 600′ in length and 15′ in height.
Take note of the train on the other side of the wall line, this is the reason for the sound wall.
The cassions holes were drilled out two feet wide and nine feet deep. Number 5 rebar was then installed into cassion and will be brought up into wall inside columns.
