Crew is uncovering a section of collapsed drain tile. Drain tile as illustrated is comprised of clay tile. Clay tile drainage system estimated at 45 years old and is in need of cleaning/repair due to sedimentation and debris.
Initial view of clay drain tile post excavation. Pipe is cracked and is allowing debris to enter drainage system, thereby clogging it. The paved surface above this portion of clay tile was actually eroding away identifying a potential problem below.
A softball-sized hole can be seen to the right of the photo. This is due to the drain pipe collapsing, thereby causing eroding of driveway base. The driveway was caving at this point indicating an issue below.
