Foundation Stem Wall Crack Repairs

This repair has been gaining considerable traction amongst our contractors that work in markets with stem wall foundations who are now utilizing carbon fiber.

Foundation stem walls can experience a variety of failures. Often horizontal cracks appear which can be the result of the reinforcing steel being too close to the outer edge of the forms when the foundation is being poured. When the forms are stripped, and if the conditions of the steel being hot on the day of the pour, a fine micro crack appears.

The concrete around the steel also begins curing outwards meeting the normal curing of the concrete, curing from the outside towards the middle. These two curing areas form a micro crack. With seismic activity or foundation settlement, the foundation may bend slightly, causing the crack to open, most of the time exposing the steel to corrosion.
