Question 1

Which type of foundation crack is generally considered most serious in a poured concrete foundation?

Accepted Answer

Horizontal cracks in the middle of the wall

Answer

Horizontal cracks in foundation walls indicate lateral soil or hydrostatic pressure bowing the wall inward, which is a serious structural deficiency requiring professional evaluation.

Question 2

What is 'efflorescence' and what does it indicate to a home inspector?

Accepted Answer

White mineral deposits on masonry surfaces indicating water migration through the wall

Answer

Efflorescence is the white crystalline residue left when water carries dissolved salts through masonry and evaporates, indicating past or ongoing moisture intrusion.

Question 3

A home inspector finds that the grade around the foundation slopes toward the house. What is the recommended minimum slope away from the foundation?

Accepted Answer

6 inches in the first 10 feet

Answer

Most building codes require the grade to slope at least 6 inches downward within the first 10 feet from the foundation to direct surface water away from the structure.

Question 4

What is the purpose of a weep hole in a brick veneer wall?

Accepted Answer

Drain water that collects at the base of the wall cavity

Answer

Weep holes are open vertical joints at the base of a brick veneer wall that allow any water entering the cavity to drain out rather than accumulate and cause damage.

Question 5

Which foundation type is most susceptible to moisture intrusion because it sits partially or fully below grade?

Accepted Answer

Full or partial basement

Answer

Full and partial basements are below grade and are subject to hydrostatic pressure and water infiltration through walls and floor slabs, making moisture management critical.
