I live in Colorado. 36" inches deep is code.
The reason it's settling is that the excavation for the house left the
soild out to about 5 feet softer. It has settled as I mentioned because
the house was new when I built the house and the deck.
How can I get under it without removing the decking. It's only about 12
inched high and crawling underneath seems like a difficult way to do
it.
The plastic is to keep the water from causing additional settling.
I appreciate your two cents. Thanks!
