Basement wall crack repair that identifies why the wall cracked, then seals vertical, diagonal and horizontal cracks with injected epoxy or flexible polyurethane.
Cracks are the most common thing homeowners notice in a basement, and they range from harmless shrinkage lines to signs of movement. A narrow vertical crack in a poured wall often comes from curing and can be sealed. A stair-step crack in block, a horizontal crack or a wall that leans inward points to pressure and needs a different plan. The first job is to read the crack, and the second is to match the repair to its cause.
We measure the crack, check for offset, look at both sides of the wall and note where moisture appears. For stable cracks, we drill small ports, flush the crack and inject epoxy to bond the concrete or flexible polyurethane to seal a crack that may move a little. We cap the ports, clean the wall and leave a neat sealed line. When the crack suggests movement, we say so, mark it with a gauge and recommend a stabilization or an engineer. A repair is only useful when it fits the cause, so we tell you which case you have. In Nashville, seasonal swings between wet clay and dry clay move foundations a little every year, so we check cracks more than once when we can.
