Old lime plaster as sub-base in garden

chriseastlondon · 2026-03-13T07:26:50+0000

Hi. I'm stripping the plaster off an old lath and plaster wall inside my house. I'll be left with bags and bags of rubble - mainly the scratch coat and float coat, made up of coarse aggregate and lime. (I'm separating the different types of plaster and the laths as I put them in rubble bags.)

Can I use these in the garden, mixed in with gravel, sand and rubble to form the sub-base for a patio?

Yes probaly won't need much sand though if you have enough plaster
