Blocks and courses
Choose Wall, give its length and set the Wall height, Block length, Block height and Block depth. The app counts the courses for the height and the blocks in each course, then adds the waste allowance. The preset is a small 11¾ × 4 × 6¾ in block and a 2 ft wall.
Caps, drainage and base
- Cap length (0 = none) counts the caps along the top.
- Drainage gravel width (0 = none) gives the gravel behind the wall and the drain pipe along it.
- Base depth (0 = none) gives the crushed stone of the base trench, wider than the block by about 6 in on each side.
Edging works from a length too: Edging, by the foot or in pieces (Piece length (0 = sold by length)).
