Hammer some wooden pegs into the ground to mark out
the area you want to concrete. Use wooden pegs about
25mm square, and long enough to be rigid when driven
into the ground. Then stretch a strong string, or twine,
between the pegs. You can cut your pegs off a length
of timber.
Next, decide how high you want the concrete in relation
to the ground around it. Remove turf or loose soil from
the marked-out area. If the ground is soft spread sand
or ashes over it to make a better base. You may have
to fill holes in the ground with stones, broken bricks or
any clean fill. Final levelling is best done with sand after
you’ve put in your formwork. When the whole area is flat,
compact it by rolling, walking or driving over it, and hosing
it lightly. The more it settles the better the foundation for
the concrete. |
