Blocks onto oak wall plate how?
I'm going to build a few layers of lightweight blocks on top of an old oak wall plate as part of roof reconstruction.
My plan is a thin layer of mortar on the oak, then blocks and mortar. Portland will be ok, not lime wont it? And I dont need a layer of DPC do I? Maybe some nails or screws down through the first layer to fix it to the oak, or between the gaps between the blocks? george (if i can get the blocks, Travis Perkins said theres a shortage of light weight blocks, the factory's shut down for a month) |

Lime mortar would be OK. ISTR I've seen straps used to link blockwork to timber as well as nails driven in. I would recommend at least for the lower courses to put in some reinforcement. Either bow tie wall ties or even lay chicken wire in the mortar: That way the blockwork wont crack as the wood moves - and it will. You can fill up any subsequent cracks with mastic. -- "Women actually are capable of being far more than the feminists will let them." |
