Need a solution to this floor issue I have please

[kilo_4que]

Basically if you look closely the stone on which the doorframe sits on raised on the left and lowered on the right compared to the floor boards. I am now ply lining the floor infact have ply lined but am stuck on this part as i dont know what to do.

Below are some photos guys

So which one is actually level, the sill or the floor? ...and is that a damp patch in the corner of the stone?

 

[i_am_fubar]

yea, check the damp patch.

What sort of stone is it?

May be worth putting ply up to the stone then leveling the stone and building it into a 'feature' step?

Deluks, yes that is damp. On the other side of door frame i.e. where the sill starts, it is like half an inch below the level of the foot path and gradually rises, Likewise water gathers up in the corner. I have thought of filling it with some cement and angling the rest of the sill/step outside so that water flows out and away from the doorway.

Regarding which is level, I havent quite check but which ever it is I cant really move the sill and would have to work around it hence the reason im stuck as i dont know what to do.

Somehow I need to get this "twisted" appearance straight, likewise what would you guys suggest?

the step should of been removed and replaced with correct hight with working DPC/DPM or joists extended and floorboards continued. You also need to do something with your patio. It is fitted way to high and bridging DPC. This WILL cause you problems in the future.

ok my plan off action as a tempory job untill you stop the source of the dampness
remove the bottom 2" off plasterboard for a foot from the door and make shure the floor boards are 5mm clear off the stone

padd out the floor with packing to allow you have 2 layers of felt on the internal stone between the ply and stone

Matty, the step is a little more complicated than it looks. It is around 4 foot deep lol

Big Al, im not sure I understand what you mean. I can stop the dampness, well i think i can as I have a definate solution to what i think is the source ofthe dampness,

However I dont understand what you meant with the rest

Personally I was think i may have had to cement the lower end of the sill and then add some self levelling compound or the sorts?

 

[mattysupra]

right the first thing you need to do is fix the damp problem BEFORE you do anything else. If you dont do this then my method to fix will not work, the compound will fail and leave you with rotten floorboards. You might want to coat the step with a liquid dpm (epoxy) !!

What you will have to do is fully plywood up to the step. Next you need to over board your plywood with more plywood in circular steps. You will end up with maybe 3-4 layers of plywood. You need to step the plywood in sections. Your first circular step may be 1meter wide, your next maybe 80cm wide so you end up with what will look like a stair case of half circles coming about a meter into the room. Do this while using a level across from the highest point. The level should touch the edge of each plywood sheet but leave a steady gap between the boards of around lets say a 20cm void of 6mm run out between them.

Is this clear?

Next you need some repair mortar ( smoothing compound ) Apply to the steps in the plywood so your finished product should now be a gentle ramp starting about 1meter away from the door. If you have done this correct the mortar should never be any thicker than 6mm deep.

next get yourself a bag of Fibre Bonded smoothing compound and apply to the whole area of your repair. This should leave you a gentle perfect slope over 1meter.

I will see if i have photos of repairs like this if you dont understand?

Im not sure i understand either, BigAl, you do realise the stone is higher than the floorboards at one end, i think you have seen where it is lower only maybe??

 

[kilo_4que]

Matty i kind of understand what your saying but I dont exactly understand how it would solve the problem where the floorboards are higher than the step?

I think a photo would defo explain how this works

 

[mattysupra]

you are raising the floor up to the level of the step and then screeding smooth but without raising the whole floor level.

 

[kilo_4que]

Matty thats the part I understand, What im saying is that currently on one side the floorboards are higher than the step. Now if i level out the other side via the method you have mentioned, the whole step would become lower than the floor boards, or is this the trick where you level out the step with the rest?

 

[mattysupra]

i cant find any photos!
The step will be made level with smoothing compound to the plywood. You have to raise the floor to the highest point of the step and then the step on its lower side to the new height of the floor (plywood)

 

[kilo_4que]

Right from what I gather going by the photos as a reference.

I need to build the left hand side of the floor up using the ply to get to the level of the step. The right hand side i sort of leave alone as the floor is higher already anyway. Once done I fill the part where the step is lower than the floor with smoothing compound?

Is this correct?
