Just small chippings about 5mm or so in size will do...they are just added to give the SLC strength when it is applied thick....some types you can add sharp sand to as well.........
Is there a trade name or do you just ask for chippings to put into SLC.
One more question how much chippings do you put in to a mix?.
ultra slc will go up to 50mm with no chippings
