Is grano same as stone dust ? Would this make any difference when benching an inspection chamber instead of just sand and cement .
What ratio would it be sand cement and grano ?
Thanks . Any particular way to get benching shaped ? More cement in one area ? Straight slope or bend with cement ? Hard to get it more rounded Or is it trial and error ?
Thanks. .What products are used ? If you could attach a photo of products for waterproofing and accerlant additives . Has it got to be straight or more rounded or trial and error . Not sure of process .
What is the mix for benching an inspection chamber ? As in sand cement etc ? Any other liquids ? Needs to stop tissues sticking on benching . Also is it trial and error ?
