complete your Anchor Stone project, you will need the following
hand tools: shovel, tape measure, hammer, chisel, carpenter's
level, stakes, string line, garden hose, safety glasses, gloves,
pencil, square. With the Windsor Stone, you may also need a compactor
and a circular cut-off saw with a masonry blade.
Begin your project by staking out the line of the border you are
making. For curved sections, use your garden hose to layout the
contour. Dig a trench along this line. If you are going to use
one, two, or three courses of block, make the trench about 3"
deep and about 12" wide. If you are going to use four courses
of block, make the trench about 5" deep and about 18"
wide. Firmly compact and level the soil in the bottom of the trench.
Place 1 " of compacted clean granular fill in the bottom
of the trench.
Position the Anchor Border Stone units side by side on the prepared
base and level in both directions using your carpenter's level.
For best results, use your hammer and chisel to remove the rear
lips from all Border Stones used for the base course. Continue
assembling additional courses by placing units in a staggered
relationship to the course beneath (running bond), pulling each
unit forward until secure.
Backfill each course with clean granular fill. As a general rule,
the backfill soil lone should extend as far behind the wall as
the wall is high. (One foot back for a one foot high wall). Compact
this soil backfill lone. Organic soil or clay type soil is not
recommended for backfill material. We recommend using 3/4"
free draining aggregate without fines.
You may need partial blocks. To split a block, use a hammer and
chisel to score the block on all sides. Pound the chisel on the
score line until the block splits. If the block does not split
easily, you may need to use a circular cut-off saw with a masonry
blade. Read and understand the operating manual before using a
saw. Always wear eye protection when splitting blocks.
