floor gets damp at base of upvc door

[goofy gorilla]

hi guys....i fitted a brand new upvc kitchen door...fitted it perfectly and sealed it from the outside and the inside...the door was about an inch to small from the ground....so i mixed some screed and cement and rested the door on that...perfect..i thought...now when it rains the inside of my kitchen gets damp...ive checked the seals, weather bar etc...water is not coming from there....i think it may be the screed and cement that i mixed ?...is this suitable for the outside ?...is it porous ?....shall i remove that and try sand/gravel and cement ?....need to sort this before i tile the floor..any ideas..ta

Need more info - but

Is the frame of the door at least two brick courses above the path/patio or what ever you have outside?

Is there a damp proof course laid in under the door frame

Sounds to me like the bottom of the frame is too close to the ground and the water is able to transfer into the kitchen from the outside

you will never prevent the ingress of water till you address the fact that you have part of your floor slab protruding into the street!

chop back the floor, lay a couple of courses of bricks, re-hash the floor slab and dpm and fit a stub sill to the door.

ok guys cheers....removed all the screed mix...mixed up some building sand and cement...filled the gap underneath....just waiting for rain now...lol..shudnt be very long mind you. ....by the way its not leading into the street its the back door leading to my garden...cant really do more then what ive done...

Agree totally with noseall you can even see the damp proof membrane of the floor slab protruding to the outside!

Very bad workmanship im sorry to say and carried out with no knowledge of building

actually that damproof course has served me well for the last 22 years...its got nowt to do with that...i removed the mix that i had from under the door frame (ie screed and cement) and refilled with builders sand and cement problem solved...no dampness getting in now...it appears that flooring screed is not for outdoor use...lets water through due the porous nature of it....anyway...thanks guys problem sorted..
