Kannapolis Spillway


The City of Kannapolis, NC was directed by Dam Safety to make some critical changes and repairs to their spillway at Lake Kannapolis Dam. HALL repaired all joints in the spillway and placed a gunite layer on the surface after removing spalled concrete areas. We also internally repaired a leaking joint, through the use of divers, in a 30″ ductile iron pipe, some 250′ up the line. HALL installed a new 24″ DIP bottom drain,increased the size of the discharge channel, and installed gabion baskets to prevent erosion.
