What sort of aggregate can I use for bedding sewer pipes.
Its currently covered in 10mm pea gravel but pipe is not fully covered. Local builders only has 20mm pea gravel in stock which they can deliver in the next day or so. Is it ok to use 20mm pea gravel?
Pipes are 100mm combination of clay and plastic pipes.
