Question 3

What is the function of a bond beam in pool construction?

Accepted Answer

Provide structural integrity to the top of the wall

Answer

A bond beam provides added structural support to the top of the pool wall, helping to tie together structural components.

Question 4

Why is proper compaction of backfill important in pool construction?

Accepted Answer
