Damp in house

[johno12345]

Hi,

I have a raft built house, 1950s brick construction on clay soil, floorboards and about 12" void between the floorboards and concrete raft.

The damp course is 2 courses above ground level at least all the way round, airbricks are fitted all the way round too.

I have problems with condensation on the windows quite a bit, and mould forming on some things at one side of the house, this side has a concrete path and the two courses of brick appear wet below the damp course.

I have got forced extraction running within the house too.

I am planning to replave the aribricks with new ones that have better airflow and add more to improve circulation.

I havent had chance to look under the floor at that side of the house, but in some areas, the concrete does appear slightly damp, not wet, just a bit damp.

Is this design of house meant to allow the raft to be damp or should it be completely dry, and is there anything else i should consider doing?

A raft would normally be damp.

If the floor void is ventilated, then that would not influence or cause internal condensation
