Some of the problems we've had in the past are because our drainage works, can be quite early on in a project, and then any other trades (who sometimes aren't quite so careful around chambers) move in so that manholes can get broken and what happens is the debris, falls down there, and then you've got to get a jetting team in to come and remove that debris, so this product catches all that debris and enables our guys to then remove that and not need to bring in anyone else.
