What kind of lumber is required on wood framing members that rest on concrete or masonry exterior foundation walls and are less than 8 inches from the exposed ground?

1) Pressure-treated lumber
2) Plywood
3) Softwood
4) Hardwood

Answer 1

Pressure-treated lumber is required for wood framing members in contact with concrete or masonry and close to the ground, due to its resistance to moisture and insect damage.

Step-by-step explanation:

The type of lumber required for wood framing members that rest on concrete or masonry exterior foundation walls and are less than 8 inches from the exposed ground is pressure-treated lumber.

This kind of lumber has been treated with preservatives to resist moisture and insect damage, which is crucial when in direct contact with concrete, masonry, or ground that may be damp. The use of pressure-treated lumber helps prevent rot and extends the lifespan of the wood in these potentially vulnerable situations.

The kind of lumber required on wood framing members that rest on concrete or masonry exterior foundation walls and are less than 8 inches from the exposed ground is pressure-treated lumber.
