Question

1. when block walls in a basement walkout are displaced laterally, chances are:

weight applied from the top of the wall contributed to the damage
the soils behind the wall have poor drainage qualities
the mortar used to set the block was poor
there is no floor drain
the footings did not go below the frost line

1. identify the problem in this picture.

Explanation:

Question 5

To determine the cause of lateral displacement of basement walkout block walls, we analyze each option:

• Weight from the top (first option) usually causes vertical issues, not lateral displacement.
• Poorly draining soils (second option) can lead to hydrostatic pressure buildup behind the wall, which can push the wall laterally. This is a common cause of lateral wall movement.
• Poor mortar (third option) affects block bonding, more likely causing wall collapse or separation, not lateral displacement.
• No floor drain (fourth option) relates to interior water, not lateral wall movement.
• Footings not below frost line (fifth option) causes heaving, vertical movement, not lateral.

So the best answer is the option about poor soil drainage.

Answer:

The soils behind the wall have poor drainage qualities

Question 6

Since the picture for question 6 is not visible, we can't identify the problem. Please provide details or a description of the picture (e.g., what is shown: structural issues, water damage, damaged materials, etc.) to assist further.
