I need advice on the following matter:
I have recently bought a house which was built in the mid 1930's. The bedroom floor on the ground floor is of the suspended type i.e. joists lying on a wall plate which is then supported by the outside wall. The room is square and measures 3metres 20 by 3 meters 20 approx.
The floor is bouncy. I got a builder in to look at it and i waspleased to hear there is no dry rot, the joists are in good condition. What is needed is a sleeper wall. The span seems to be too long and why a sleeper wall was not originally built in i do not know.
The joists are 5 inches by 2 inches.
I plan to do the following:
in the middle of the room lay a bed of mortar on the sollom(the sollom looks like a tar substance, someone called it bitumen). Then lay bricks on this mortar in the honeycomb fashion (to allow air flow under the floor). At most the wall will be 3 brick high. I then plan to lay a roll of damp proof sheet on top of the brick before using bits of slate fitted in snugly against the joists.
I would appreciate any advice or information on this matter,
regards
scott
