Question 1

When setting fence posts in concrete, how should the top of the concrete footing be finished?

Accepted Answer

Slightly crowned above grade to shed water away from the post

Answer

Crowning the concrete slightly above grade directs water away from the post base, reducing moisture intrusion that causes rot in wood posts and corrosion in metal posts.

Question 2

Which post type is required at corners, ends, and gate locations due to the greater structural loads at these positions?

Accepted Answer

Terminal post (corner or end post)

Answer

Terminal posts are larger and set deeper than line posts because they anchor the tension of the entire fence run and must resist greater lateral and pulling forces.

Question 3

A fence post that is not plumb after being set in fresh concrete is best corrected by:

Accepted Answer

Adjusting the post position before the concrete cures

Answer

Plumb corrections must be made while the concrete is still workable; once cured, the post cannot be adjusted without demolition and resetting.

Question 4

To prevent premature rot, wood fence posts that will be embedded in the ground should be:

Accepted Answer

Pressure-treated with preservative rated for ground contact (UC4B or higher)

Answer

Ground-contact pressure treatment (UC4B or UC4C) penetrates the wood fibers with preservative chemicals that resist fungal decay and insect attack below grade.

Question 5

For a chain-link fence installation, what is the typical maximum spacing between line posts?

Accepted Answer

8–10 feet

Answer

Chain-link line posts are typically spaced 8 to 10 feet on center; closer spacing may be needed for taller fences or high-wind areas.
