Just completed Structural Foundation repair using Carbon Fiber Straps. After strong rains, Hydrostatic pressure pushed the wall 1" inward causing astructural crack along perimeter of entirefoundation wall on two adjoining walls. Carbon Fiber repair was suggested by an architect and being certified installer, I completed the repair.
Carbon Fiber straps installed 4' OC and prior toinstallation andas you can see, the block must be plained using special concrete dustless grinder to prepare surface for the Epoxy. After Epoxy is applied, the straps are installed to stabilize foundation wall and prevent further lateral foundationmovement. . The open joints are filled with hydro cement to preventfoundation wall from move outward during cold climate.
Strap is 4 1/8"W x 1/8"Thick can be easily installed behind mostmost plumbing pipesor electricalcomponents without removing or re-routing them. The wall can be painted orfinished by applying cement parging. This is the most advanced structural repair, without usingextreme invasive methods of repair,i.e steel beams, excavation, etc. The Carbon Fiber strap can withstand Hydrostatic pressure10 times morethen the steel beams embedded in concrete to support foundation wall.
