I have bought a wall starter kit to build a new internal partitioning wall. The new wall will be built from 100mm blocks. The starter kit needs to be fixed to the inner leaf of one of the exterior walls.
The problem I have is that the inner leaf is built of hollow concrete blocks. The wall starter kit is supplied with 50 mm long coach screws and wall plugs, but the shell of the hollow blocks is only about 20 mm thick, which obviously makes these fixings a lot weaker. The kit was only supplied with 5 screws for a single storey wall, would I be OK if I just buy some extra screws (say 5 more) to compensate? I don't want my new wall collapsing when someone leans too hard on it. Am not really sure what other type of fixing would be better in this case, because the hollow shell itself isn't that strong in tension for example resisting being pulled outwards.
