A one story house was damaged by mine subsidence movement. The house is located in a small subsidence sag and is experiencing differential settlement and compressive ground strains. Instead of waiting for the ground movements to eventually stop, The Illinois Mine Subsidence Insurance Fund developed a permanent repair scheme that was implemented at the same time damaging mine subsidence movement was affecting the structure. This repair provided a significant structural resistance against the anticipated residual mine subsidence movement and was aesthetically acceptable to the homeowners. The repair consisted of epoxying vertical and horizontal steel straps and then applying a cover coat of fiber-cement on the unreinforced concrete block basement walls. The repair scheme was relatively untried, but had been successfully researched. This paper provides information on the mine subsidence movement/damage, the design concepts of steel strap/fiber-cement repair, construction details, performance and costs. Other applications of the use of the steel strap repair method are also discussed for releveling of a building and/or correcting subsidence damage to structures located in the tension zone.
