Question
Building a new home and I am considering doing a Wood Basement.  Any Pros and Cons of doing a wood basement over poured concrete?  Thanks

Answer
Dear Nathan,

All-wood basements are great for well-drained sites that have stabile soils. They allow easier construction and insulation and provide more options for penetrations such as windows, vents, and utilities.

The main drawback to them is that they are not appropriate for use in wet soils. The ground will push on them and eventually bow the walls inward. The other objectionable trait is that they are composed of treated wood, which is toxic and does not last forever.

Even dry soil can push the walls inward if the interior wall is not sheathed before the building is backfilled. All plumbing, electrical, insulation, and plywood interior sheathing must be complete before dirt is placed against the wall.

I hope this helps.

Daniel
