Help building retaining wall on a slope with footing.

Hello all. First time poster here and I was hoping to get some insight on a project I am working on.

My driveway was narrow so I decided to take down the wall on one side. I removed the wall and dug out most of the dirt and now I am ready to put a new wall up.

I plan on using cinder blocks to make the wall. I was told I should definitely make a footing to build the wall on. Problem is the driveway is on a big slope and I'm not sure how to do a footing like this.

I am going to attach some pictures so you can see what I am working with. I would like the new wall to match the wall on the other side of the driveway as close as possible.

How much footing will I need if using cinder blocks? How deep do I pour it and how wide? I live in RI so I'm not sure how far I need to go down with the frost or if that is even an issue here.

As far as the wall goes should I be using rebar inside of the cinder blocks or can I use some fill inside of the holes? I have seen some videos with small black drain pipes installed, is this needed? There are some free cinder blocks available for pickup on some local trading websites. Should I grab these to save some money or am I better off with buying new blocks?

I would appreciate any tips/tricks or information anyone can give me. This is my first time ever building a wall and I would like to do it correctly without spending a fortune. Anything that will make my life easier? Please assume that I do not know a whole lot. I do have some friends/family who are helping me with this but I would like to go into the project with as much knowledge and understanding as possible.

Good luck building the wall with "cinder blocks", as cinders have not been used in block since the 1970's!!!

With freezing and thawing and hydrostatic pressue, you don't want to build a wall with masonry block.

Use segmental wall block. no mortar used. so the wall wont crack.

And as far as the frost line for your area - try a Google search.

As others suggested, this may not be a diy project. Regarding the slope, you will need a stepped footing. You can google search that. Cinder block is not going to be a good choice for material. Get some block made for retaining walls that lock together and fill with stone. The proper footer and drainage is the key to a good retaining wall

Go with SRW blocks. Start here: http://www.versa-lok.com/document-library
Consider purchasing the Segmental Retaining Wall Installation Guide book from the NCMA. It'll be $30 after shipping.

If you are a homeowner, consider calling some contractors for this too. To me that looks like some pleasant conditions - so the prices may not be as bad as you think.

I find this subject pretty interesting. I see tons of SRW/paver use on this forum and much less concrete/CMU/mortared stone work. Here it is pretty much the opposite. We use tons of CMU, chopped stone walls with mortared joints and slabs on grade with flagstone.

For instance, neglecting frost heave, we would use a concrete step footing with steel stubbed up which we would tie our CMU steel to. We stack everything then pour concrete in the void to tie everything together. Either that or use 6x8 mortared limestone block. Definitely not saying SRW/paver use is wrong, just fun to see the difference in methods regionally.

To the OP, this is probably a bigger challenge than you will want to take on about 1/3 of the way through the project.

Yeah no duh. A specialist can do anything if it's their area of expertise.

Specialists don't ask for help......
