Seasonal Water Risk in the Dennison Area

Soil Conditions & Foundation Types in Dennison, IL

Clay-dominant ground conditions, which are prevalent throughout much of IL, hold water for extended periods and push it sideways against below-grade structures. Knowing the ground composition around your Dennison property is why our assessments start outside the building, not inside the basement.
