Today I emailed our PM three questions. They were:
-What material are you using for backfilling?
-How would you rate the density of the backfill material?
-What method do you use to ensure proper compaction aroundthe exterior of the basement walls?
He was very prompt in his reply:
He said they use dirt from the excavation as backfill material. The dirt does get air pockets that over a period of time will work they’re way out, usually after rain. Some settlement around the foundation during the construction process is common. Ideally we wont get any settlement after the house is finished, but if we do, Ryan will come back and fix it. He said its much more common in houses built over the summer due to the dry climate and dirt.
These questions steam from seeing settling at the model home in our community.
