18. What is self-weight vs. dead weight? Self-weight refers to the weight of the structure itself, including the materials used in its construction. Dead weight is a term used to describe the permanent, non-moving loads on a structure, such as the weight of the walls, floors, and roof.
19. What is the difference between a gravity wall and a retaining wall? A gravity wall is a type of retaining wall that relies on its own weight to resist the pressure of the backfill. A retaining wall is a broader term that encompasses various types of walls used to retain soil or other materials.
20. How deep should backfill be for a retaining wall? The depth of backfill for a retaining wall depends on the height of the wall and the specific design. Generally, the backfill should be level with the top of the wall or slightly below it.
21. Does a retaining wall have to be perfectly level? While it is ideal for a retaining wall to be as level as possible, slight variations in elevation are acceptable as long as they do not compromise the wall’s stability.
22. What is the best base for a retaining wall? The best base for a retaining wall depends on the soil conditions and the type of wall. Common base materials include compacted gravel or crushed stone.
23. What do you backfill a retaining wall with? The backfill for a retaining wall is typically filled with a suitable material, such as gravel or crushed stone, to allow for proper drainage and reduce the risk of soil settlement.
24. How deep should the first course of a retaining wall be? The first course of a retaining wall should be dug into the ground to provide stability and prevent shifting. Typically, it should be buried at least 4 to 6 inches below ground level.
25. Should water come through a retaining wall? Water should not come through a retaining wall. Proper drainage behind the wall is essential to prevent water buildup and potential damage.
26. How much slope before a retaining wall is needed? The need for a retaining wall depends on the slope of the terrain and the soil conditions. Generally, a retaining wall is necessary when dealing with steep slopes or to create level areas.
27. Do I need to put landscape fabric behind a retaining wall? Landscape fabric is optional but can be beneficial in preventing weeds from growing behind the retaining wall. However, proper drainage is more critical for the wall’s long-term stability.
28. Should you put black plastic behind a retaining wall? Using black plastic behind a retaining wall is not recommended as it can trap water and lead to drainage issues. It is better to focus on proper drainage and backfill materials.
29. Do retaining walls need weep holes? Retaining walls that are over a certain height may require weep holes to allow for proper drainage and to release water pressure behind the wall.
30. Does a dry stack retaining wall need drainage? Dry stack retaining walls do not require mortar, but they still need proper drainage to prevent water pressure buildup behind the wall.
31. How much does a 4x8x16 cinder block weigh? A 4x8x16 cinder block can weigh between 26 to 34 pounds, depending on the materials used.
