Heave is a commonly occurring phenomenon in areas where clay-rich soils constitute a large portion of the overall soil composition. Expansive clay soils damage commercial and residential structures over time by expanding in wet conditions and contracting in dry conditions. As this process occurs, the soil beneath a building's foundation grows and shrinks, exerting uplift forces on the structure's foundation. Lab tests have demonstrated that expanding clay soil can exert an uplift pressure of over 5000lbs. per sq. ft. - more than enough to lift a concrete slab.
Arizona Foundation Solutions has pioneered a moisture remediation solution proven to mitigate the effects of soil heave. The MoistureLevel Smart Foundation System borrows from our radon mitigation technologies, using a fan and plastic exhaust piping to create air movement and exert suction forces on the under-slab soil. Introducing outside air to the damp soil causes evaporation to occur, allowing the condensed vapor to be removed in the form of liquid water:
Our experts are ready to give you the help you need. With decades of experience in heave remediation, we are Arizona's go-to professionals for permanently alleviating uplift forces on commercial structures caused by expansive soils.
