  • Anyone had experience of retrofitting a physical DPC in a wall?* Pretty sure mine original DPC is bridged in a way that would make it unfeasibly destructive to cure (concrete floor in Victorian building) unsurprisingly DPC injections have done nowt. Not sure given the non-period floor that the heritage/lime plaster approach would work.

    *Just to be clear I would GSI not DIY lest my house falls down.

  • No idea, but it sounds like a nightmare of a job that you'd only consider after all other avenues have been tried.

    Is the concrete floor attached to the inner brickwork? Is that how the original DPC has been bridged?
