Schedule Free Inspection

House Description:

This single story ranch style house in Arab Alabama is a single family home with an attached garage.  It was built in 1976.  A sidewalk extends from the front porch steps to the garage.  The sidewalk and front steps experienced settlement over the years.

Problem Description:

The steps at the front of the house has experienced approximately 2 inches of settlement.  The sidewalk that connects the front steps and the garage had also experienced settlement.  Approximately ½ inch of settlement was experienced in the sidewalk.


AFS’s inspector assessed the situation.  Sidewalks around houses are usually the last piece of construction to be made when a house is built.  Many times, the ground beneath the sidewalk is not as well compacted as the soils under the house foundation.  Additionally, water can find its way under the sidewalk during periods of heavy rain.  During these events, water can erode the soil under the sidewalk, creating voids which will allow the sidewalk to settle.  SettleStop Concrete Raising was a clear choice to recommend to the homeowner to repair the sunken concrete.


SettleStop Concrete Raising is a two part polyurethane expanding foam.  It is injected under concrete through small penny-sized holes at regular intervals.  When injected, the two parts of SettleStop Concrete Raising meet and are mixed.  Until this moment, the two parts are liquid.  Once they are mixed at the tip of the injection gun, the two parts undertake a chemical reaction and is converted into foam.  The foam expands in seconds, filling any void it finds.  As it expands, all the voids are filled and the SettleStop pushes up on the sidewalk and down on the soils.  In doing so, the concrete is lifted.  SettleStop Concrete Raising is stable after only a few minutes, and by the time the AFS crew has cleaned up and packed up, the SettleStop is fully cured and ready to provide years of stable service.
