soak away

[itfc]

My soak away has sunk. anybody got ideas on how to fill it. some say fill it with sand and rubble but not sure.

Get a bag of large gravel from B&Q and if necessary some sand on top.

Think the large gravel is right, but don't think sand should be used it is too small and will seal up porous requirement of the drainage. Should be small pebbles such as used for harling walls etc
