Concrete Blocks

   Like other masonry materials, concrete blocks tend to be manufactured locally and will vary in price and variety from place to place. Three types of blocks are generally available: standard, interlocking, and decorative blocks. Blocks are usually priced individually, with price breaks for large quantities.
   To determine how many blocks you need, sketch out the project, showing the number of courses, how many blocks per course, and how the corners will be finished.
