4 in. x 11.75 in. x 6.75 in. River Red Concrete Retaining Wall Block

The face is 11.75”, the depth is 6.75, and from looking at other fire pit photos, the relief is 15°. That means the minimum inner radius at the center point of the face is 15 3/16”, and the average inner diameter of a ring is, at a minimum, 30 3/8”. avg(IR) = W / ( 2 x tan(ra)) - D, and ra = 360 / number of blocks to make a ring.

Yes, 21 blocks make a nice firepit that is about a foot high (3 levels). Remember to bury the first block halfway in the soil. They take heat really well since they are not hollow.

38 but you can use the calculator above. Length x height x 1.1 For a slope divide the above result by 2.

Yes. That is exactly what they are designed for. There are many videos on YouTube from Pavestone on how to build the wall.

The block’s volume is roughly 1/6 of a cubic foot. Concrete’s density is, also roughly, 150lbs/cft, so back of the envelope guess would be about 25lbs, so 22 lbs for a sintered block material seems about right.

This product ships 144 pieces per pallet.

These are not pavers. They are wall block. You would not use these for a patio floor.

Take a Masonary chisel use it to score a line on the block then put it in the middle of your line and hit it harder. The block should split where your line was.

I have two smaller areas where I've built these up to 24" tall without a footer/foundation They settled slightly over a few years Nothing significant

no you have to cut the size you need
