Unable to drill holes directly above the settled concrete, polyurethane was the only option available for repairing this Milk House Floor in Fond du Lac County. The polyurethane flows from the injection point along the void, pushing out water. After the void is filled with polyurethane, the concrete is raised. This takes the pressure off of the bulk tank, which was damaged in the settling process. The polyurethane also acts as a barrier to keep water out in the future, and avoid having the concrete re-settle.
