A Simple Guide"},"content":{"rendered":"\n

Before you order cover blocks<\/a>, you need a count. Here is a simple way to work it out.<\/p>\n\n\n\n

For a slab or footing<\/h2>\n\n\n\n
    \n
  1. Choose the gap between blocks. Many sites use a gap of about 2 to 3 feet. Ask your engineer.<\/li>\n\n\n
  2. Count rows: divide the length by the gap, then add 1.<\/li>\n\n\n
  3. Count blocks in each row: divide the width by the gap, then add 1.<\/li>\n\n\n
  4. Multiply rows by blocks in each row.<\/li>\n<\/ol>\n\n\n\n

    Example:<\/strong> a slab of 30 ft by 20 ft with a 2.5 ft gap. Rows = 30 \u00f7 2.5 + 1 = 13. Blocks in a row = 20 \u00f7 2.5 + 1 = 9. Total = 13 \u00d7 9 = 117 blocks.<\/p>\n\n\n\n

    For a beam or column<\/h2>\n\n\n\n
      \n
    1. Divide the length (or height) by the gap, then add 1. This gives the number of points.<\/li>\n\n\n
    2. Multiply by the blocks at each point. For example, a column often needs one block on each side.<\/li>\n\n\n
    3. Multiply by the number of beams or columns.<\/li>\n<\/ol>\n\n\n\n

      Add a little extra<\/h2>\n\n\n\n

      Some blocks break while moving them around the site. So add a small extra, like 5%.<\/p>\n\n\n\n

      The easy way<\/h2>\n\n\n\n
