August 9, 20215 yr I'm extending a shed base which needs some infill and also have a lot of old plaster from a few lath and plaster ceilings. Any reason not to chuck it in the mixer with some new cement as a binder and use it to fill in? it's got no load to speak of and once down will be under solid concrete.

August 9, 20215 yr Yes as if it is gypsum based it is nasty stuff that will absorb water and also can cause lifting and swelling of the ground. Lime plaster is not an issue in this sort of situation.
August 9, 20215 yr Author That's good as it's It's mostly 1930's old lime plaster, with the odd bit of modern drywall, but that's easy to remove. Thanks for the reply
August 9, 20215 yr Take the rest down to your local tip in suitable bags, and they may well have a suitable skip.

Lime plaster is not an issue in this sort of situation. I was doing some work on a house being refurbished recently. The owner wanted to build up some ground to lay a raised patio. I saw all sorts of stuff going into the hole, including a load of the plasterboard that was ripped off. It would be interesting to see how that works out.
