Question

cracking, leaning or bowing retaining walls for basement walkouts are less serious than spalling masonry or concrete, or mortar deterioration are easily remedied through reducing the lateral soil pressure by improving grading are caused by frost pressure and hydrostatic pressure may indicate damage from railing anchors rusting may be caused by free - draining soil conditions question 26 cedar is not a good choice for cantilevered balconies because it is resistant to rot it is not very strong it cannot be pressure treated it is too expensive to be used as a framing member it does not make as dramatic an architectural detail as other softwoods

Explanation:

For the first question, cracking, leaning or bowing retaining walls for basement walk - outs are often caused by frost pressure and hydrostatic pressure. Spalling masonry etc. can also be serious but not directly comparable in a simple less - serious way. Reducing lateral soil pressure by improving grading may not easily remedy these issues. Rusting railing anchors are not the main cause and free - draining soil conditions are not the cause.
For the second question, cedar is not a good choice for cantilevered balconies mainly because it is not very strong. Resistance to rot is an advantage not a drawback. It can be pressure treated in some cases, cost is not the main reason for not using it in this context, and architectural detail is not the key factor compared to strength for structural elements like cantilevered balconies.

Answer:

First question: are caused by frost pressure and hydrostatic pressure
Second question: it is not very strong
