Retaining wall?

Question

Im going to build a retaining wall behind my house and Im using concrete blocks to do this, what I need to know is how deep and thick does the footing need to be?

Answer 1

For that answer you are going to have to check with your local city's building code. In my town, its 18", and thats actually a pretty common depth for the first course to be set at. Also, since you are building a retaining wall, dont forget about the rebar. This you'll wanna place vertically inside of your blocks. If you are living in a colder climate, one that has alot of snow, the depth may be more due to frost conditions. Your best answer for its depth though wil come from your city's code. Now..... If you have questions about how to lay the blocks.... Ask another question daniel son.....

Answer 2

Depends where you live, the type of soil, what kind of and the slope of the soil it's "retaining," and the local building codes. Talk to a local home store for info.

PS--Don't forget the rebar!

Answer 3

It depends on the climate in your area. In upstate NY, footings need to be 4 feet deep. Check with your local building inspector, since he or she will be the one to inspect the footings.(You do have a building permit, right?)

Answer 4

first you gotta get some re-bar and some good cement the footing should be around 15" inch
deep per every five to six feet depending on your areas building regulations remember the re-bar you defiantly need re-bar

Answer 5

This depends entirely on the climate where you live, and what the soil structure is.
Your best bet is to talk to some local builders' supply stores, contractors, or gardening supply stores for their advice.

Answer 6

Contact your City and find out what they're codes are. Then follow their directions.

Answer 7

this depends upon the height of the wall and other factors such as soil and moisture.
