Answer: 
For a 4 FOOT tall, 48 FOOT wide, 7 INCH deep wall, you will need 576 blocks. The specs on the blocks indicated each is 12' x 7" X 4" (l x w x h), or alternatively, 7" x 12" x 4". For a 4 foot high wall, it would take 12 stacked @4" each. For a 48 Foot long wall @ 12" (1 foot) each, it would take 48 blocks side-by-side. Therefore, 12 x 48 = 576. Home Depot recommends the blocks be limited to 2 feet tall, Read More
For a 4 FOOT tall, 48 FOOT wide, 7 INCH deep wall, you will need 576 blocks. The specs on the blocks indicated each is 12' x 7" X 4" (l x w x h), or alternatively, 7" x 12" x 4". For a 4 foot high wall, it would take 12 stacked @4" each. For a 48 Foot long wall @ 12" (1 foot) each, it would take 48 blocks side-by-side. Therefore, 12 x 48 = 576. Home Depot recommends the blocks be limited to 2 feet tall, probably because the blocks are only held together by gravity, and there are no projections and indentations in the blocks to tie them together. One can use strong concrete adhesive between each layer, thereby increasing the lateral strength such as the pressure of water behind it. Further, Uniform Building Codes (UBC) require a footing and rebar to keep a wall greater than 3 feet tall, plus a 42" railing to keep people from falling off onto any surface within 3 feet of the edge. Home Depot's recommendation of 2 foot height limit avoids all that. "Slim's" question seems to infer an inappropriate use of these blocks. Read Less

First this block isn't made to go that high. It is rated for only 2'. For that size you will need about 48 blocks.

Other answers aside, a 4 foot high by 48 foot long wall of these blocks would require at least 12 blocks in height (4 inches = 1/3 foot), and 48 blocks in width. This tolals 576 blocks and is the Minimum number for the wall dimensions given.

Sorry for the wrong info. They are 7" deep. They measure 4" high so you would need 12 high to get to 4'. So the total would be 48. 4 per row @ 12 rows.

Answer: 
Ok so they are 12" wide so that would be 4 blocks to make the length. They are 7" high so it won't come to 4' so you will either use 6 high to come to 42" or 7 to come to 49". If it needs to be right at 48" then you could dig down an inch to make it 4'.

Answer: 
You can make a 90deg sharp corner as well as make a 90deg turn via a gradual curve. Turns have to be gradual though. You have to join the straight edges together to make the turn. You can cut the blocks to make them shorter but I would not recommend it unless you are gluing all the joints because a shorter block makes more seams which then makes the wall much weaker.

Answer: 
You will have to cut the blocks in order to make a corner. To cut the stone, start by measuring the size of the piece you will need to finish that row. For cuts that are 1/2 of a stone, you will notice that many of the stones have a groove in the backside of the stone. This is a built in stress point to help you split stones in half.

For cuts that are 1/2 of a stone, you will notice that many of the stones have a groove in the backside of the stone. This is a built in stress point to help you split stones in half. Start by scoring the wall piece around all four sides with a heavy-duty 3 inch masonry chisel with a hand guard and a hand sledgehammer. Simply roll the stone onto its face with the back sticking up in the air. Then set the chisel into the groove and strike it with the sledge hammer. After a couple blows the stone should split in half. Read Less

Answer: 
You will have to cut with a (diamond) mortar saw at 45 degree. Don't waste your time or money with a hammer and a chisel (chisel won't work for such a thick brick). Use a good respirator, a fan, hearing and eye protection while cutting if it's a dry method.

The wall will not be retaining a load so there wont be excess pressure on the wall. I would recommend the glue if there is the chance for kids to want to jump on or off these.

Rated 4.6 out of 5 by 56 reviewers.
Rated 5.0 out of 5.0 by Nice quality block This is a nice upgrade from the standard style retaining wall block. Great color combination/style and adding the capstone really sets it off. July 5, 2016
Rated 5.0 out of 5.0 by A very doable, rewarding project! Wanted a corner, raised flower bed without having to do too much cutting or concrete work. The blocks were great to install and the project was done in about 2 half days. May 10, 2016
Rated 5.0 out of 5.0 by my retaining wall A little more money but worth the slate look! Im a happy consumer! Used a diamond blade to make the corner cuts. April 26, 2016
Rated 5.0 out of 5.0 by Fire pit I used these retaining wall blocks to build a fire pit. Most kits are about 30 diameter burning area and I wanted a larger area and didn't want to spend hundreds of dollars. I simply modified the blocks by hammering off the lip to flatten each block. A rock hammer tool is ideal for this but a regular hammer will work. The outer diameter is about 5 ft and the inn is about 4ft or 48 inches. The cost of the 48 blocks was about $140. Enjoy the pic and video! July 29, 2015
Rated 4.0 out of 5.0 by Easy to work with I removed one star for variations in the color. As others mentioned, you have to dig through pallets to find what you think the color should be. Because uncapped stones look too much "DYI" to me due to triangular holes and there are no corner blocks, for best result expect to cut the stones. Diamond blade on a circular saw is your minimum investment. This generates a lot of dust, so be sure to use a respirator and a fan. I set the top with a mortar and filled a spaces on the caps as if they were tiles. This should be fine for a small area where it doesn't snow. May 26, 2015
Rated 5.0 out of 5.0 by These wall blocks were a snap to install. Once you get the first course leveled, the rest go up like a dream! These wall blocks were a snap to install. Once you get the first course leveled, the rest go up like a dream! I'm a 55 year old woman who has a desk job, so this is not something I do every day. And yet, I could do this all on my own, except for the cutting of the capstones. I had to hire someone to come to my home and cut them for me. It was an additional expense I hadn't originally planned for, but it was SO WORTH IT! The stones are gorgeous! The quote we got from a local stonewall company was outrageous ($5K for a 25' wall?), so this was a really budget friendly alternative. We now have 25 feet of seating space in the back yard that we didn't have before. September 12, 2013
Rated 5.0 out of 5.0 by Great stones These stones were great. I ordered a pallet and did a retaining wall and a flower bed. Out of 144 stones maybe 10-15 were broke beyond use, but overall they look amazing. I was able to use some of the designs from others to make my wall really pop. To build a wall/bed you need- shovel/hoe, river pebbles or sand, dead blow hammer, beer, pizza, a level, something to cut the stone (I used 7 inch masonary blade for circular saw), cocnrete adhesive if putting caps on. tips- start at low spot, use spray paint or string for straight line, use 1 foot and 4 foot levels, use sand or river pebble rocks to help level, plan your drainage, dont over use the circular saw blade as it overheats easily. Also I had the pallet delivered for $65 or so, which was better than I would have guessed. Also, you spend 90% of your time getting the base level and ready, then it goes up fast. June 3, 2015
Rated 4.0 out of 5.0 by Good blocks I built a 75 linear foot retaining wall using about 400 bricks. First of all, I ordered these online because I needed 400 (I accidentally ordered 500 but home depot happily returned them) and the shipping went flawless and none were damaged during shipment; however, they did have scuff marks which I'm sure will come off with time. Also, the colors were varied and I got a little more of the tan ones. Also, you should use construction glue when stacking these because the lips were damaged (looks like form the factory) on a lot of them and could probably not hold up to much pressure. It took me about a week to dig the trench (working a few hours each day) because the ground was very compacted and then I filled it with liner and paver base with sand on top. I started placing the blocks and leveling them with a torpedo level and a carpenters level. However, I ran into an issue because a few of the blacks were not flat at the top! This is why the torpedo level came in handy. Make sure to look for these. After laying down the first layer, the next ones were easy to place, however, on curves the blocks wont always fit right so you may have to remove the lip from them to get the turn to work better. Some tips: Be sure to remove the lips on the ones that are at the base, remove lips off turns and use construction glue, alternate color and design randomly, dont forget to add wall caps at the top for a cleaner look. Do these and you should have a nice wall! Oh and before I forget, thanks to Home Depot for refunding me the difference of the regular price and the promotional price of the bricks! I ordered the bricks a week before they went on sale and they gave me back the difference. June 11, 2015
