I planning on extending a concrete base that my greenhouse is currently sat on. One edging face of it is beginning to crumble away so I thought that extending that edge by a further 12" should help preserve it?
I seem to recall hearing that PVA solution should be applied to the edging face of the existing concrete base so the new concrete will bond to it.
Is this true?
