Soil Compaction in Residential Construction
1989/10/01It's not hard to spot some of the results of poor soil compaction around a house. Cracked foundations. Concrete steps that lean away from the house. A cracked and settled garage slab with one part higher than the other. Rain water running toward the foundation instead of away from it. All these flaws mar appearance and reduce resale value for the property but
