* If you use only sand, add stone dust tonnage to sand.

Level the edge of the circle, from the turf removal line up to 30 cm
(12") within the circle.
To do this, use a carpenter's level set on a large straight beam, a
rope or an optical level.
Carefully pack the soil using a tampering tool or vibrating plate (See
Illustrations 2.1 and 2.2), especially those areas where a large
quantity of soil was added.
It is also highly recommended to firm up the edge by adding a 2
cm (3/4") layer of stone dust (or sand).

The center of the circle can then be excavated at the desired depth,
not to exceed 15 cm (6") for a standard liner (See Illustration 2.3).
Remove any stone, pieces of wood or other debris from within the
circle. Flatten any protrusion and pack the soil tightly. Spread the
area with salt to prevent roots from growing back and to eliminate
earthworms. Spread also ant repellant; all causes of post-installa-
tion cracking.
To protect the liner, cover with a think 2 cm (3/4") layer of com-
pacting sand.
Make sure you add a sufficient quantity of sand to the base finishing
inside the circle (See Step 6).
