Right are some of the pictures from the Iowa Speedway now under construction. They were having a bad subgrade problem with water leaching through the banking of the future track surface. We were asked to install a 6" subdrain around the outside of the track to intercept the water before it crossed under the track. This subdrain had to be installed from 8' to 14' deep. This is a lot deeper than what our equipment can handle. We contacted Robinson Service Inc. from Earlville, Iowa to install this portion of the subdrain. They brought in a vertical trencher (right) which was set up with a 16" boom to accomplish this project. We assisted in the backfilling and compaction of the trench. This manpower came from Dick Prusha and his milling crew and Jake Boyer in the trackhoe compacting the trench. We still have approximately 6000' to install around the inside of the track with Bob's crew this year if the weather will allow.
