Step 2

 

Dig a hole which is about 30 cm (12 inches) square and about 40 cm (16 inches) deep. If you save the piece of lawn removed, you will be able to replace it later.

 

Place some small stones in the bottom of the hole, just under the bottom end of the socket and surround them with cement, this will allow rainwater to drain away.

 

Be sure the fill is enough to bring the top of the socket just below the level of the lawn, if the top of the socket is protruding it will prevent you from running the lawnmower over this spot, so leave it just below the level of the soil.

Now fill the rest of the hole with concrete, if you leave it below the level of the lawn you will be able to replace the sod that you removed earlier.
