    I have an area where rain water has pooled against an external wall of a 1900s terrace. The bricks are now damp. There are no air bricks. The ground outside is raised concrete. I am thinking of bringing down the outside level and installing a aco drain. I will install some air bricks and clear out the cavity in the bottom few rows. There is cavity wall insulation in the wall. If I clear out the cavity as much as I can how do I stop the remaining insulation dropping to the bottom. I have been told gutter brushes can be pushed into the cavity. Can this be done? Does this make sense? I can't afford to have all of the insulation removed completely

    Doubt there is a cavity given age of property.

    Series of holes in bed joints and lock the insulation in place with expanding foam ;)

    Not really, by the 1920’s cavity was more widely used than solid but it was definitely used in the 1890’s:)
    CGN and Severntrent like this.
