How many blocks for a 6ft by 105 ft wall?

How many for a 6ft 200ft wall

The 6 I just got from the store are closer to 7 5/8 x 7 5/8 x 15.5. Is that how they are supposed to be?

The store label and my receipt say 8x8x16... I'm not a mason, is it common for them to be so short? Or is it done this way to force customers to by more then they need? I need 24 inches high, not 23...
Asked by: GG
The "finished" size of your block will be the size stated. The blocks are made to this slightly reduced size to allow for the mortar mix between the blocks.

how much does a single block/pallet of these blocks weigh?

I have a trailer with 2- 3500 pound axles, I'm wondering how many pallets I can safely carry.
Asked by: Shinybutt
Same question was asked & answered on March 9, 2018 Depends on the block style. I just was told 35 pounds for a 8x8x16". Some here say 36.5. To calculate the load in your truck, I'd just go with 37 pounds each.

16 in. x 8 in. x 8 in. Concrete Block is rated 4.4 out of 5 by 69.

Good price at the amount I purchased. I made a fire pit out of them and capped them with a similarly made concrete paver. Used Loctite PL500 to glue them together and Quickcrete cement color diluted with water and sprayed on. Took about four coats to get the color depth I wanted.

Recommend delivery since I Purchased 120 so I didn’t have to lift them multiple times and got 2 cool pallets to use as hanging planters for free!

The only two downsides to the product are the weight (they're a lot heavier than the lite-weight blocks that home depot used to carry) and when I buy pallets of them sometimes some of the blocks are broken or chipped. Other than that though they are great! We use them when setting up mobile homes and they really are strong and sturdy.

Because of cardiomyopathy and congestive heart failure I get very dizzy and about pass out when I bend over. So, I used the Oldcastle concrete blocks to build my raised beds so I don't have to bend over. My brother and niece helped me build the raised beds. I don't use motor which helps in keeping the right amount of moisture in the beds especially after heavy rains. The bed on the left is my salad raised bed. The two in the middle are strawberries. The short bed is carrots and beets. The back bed is half strawberries and the other half is onions.I recommend using concrete blocks because the beds will last for years and years! The only drawback is occasionally I have to re-stack a couple blocks here and there due to expanding and contraction but it's a small price to pay to have fresh veggies! btw... I built the screens to keep the squirrels and my chickens from eating my veggies :)

I was disappointed at the difference in quality between the blocks we got in March (which were great) and the most recent load of blocks we got this time (in May). This most recent load of block had a much rougher consistency than the relatively smooth blocks we got in March. These recent blocks were also slightly smaller than the first load.
