SB: Re: Re: Re: Re: Question about strawbale house on stilts
Hi Paul....I was attempting to point out that if a native soil exists at 95%
to 120% of lab compaction, and fill is placed at 90% lab compaction, the
fill will settle more than the cut area. If the soils are as you describe,
the cut area will settle more than the compacted fill.
