Customer Questions & Answers

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
When you add a 3/8 in grout line, you will get the true 8x8x16. The blocks are designed to be short to accomodate for the mortar.

quantity of block needed for a 44 foot long three row wall
Asked by: tino
44 feet times 12 inches per foot = 528 inches divided by 16 inches per block = 33 blocks per row times three rows high = 99 blocks. I always order a few extras to allow for cutting or broken blocks.

Oldcastle Product Support states that fly ash "may sometimes be included in the mixture". Since I am considering using these blocks for a raised garden bed to grow food, I am concerned about the level of toxicity due to fly ash. Can you please be more specific of the percentage of fly ash that "may" be used, at least state the maximum percentage amount that could or would be used? Several people have asked this question for gardening and I'm sure we all would like a clearer answer than previously stated. Thank you.
Asked by: Kbunny
Every lot shipped should have listed from the manufacturer the components of the blocks, e.g., if it is manufactured using fly ash. It would be similar to stating 'poison may sometimes be included in the mixture' so a general statement is unacceptable.
