Why you should do a bounce test and then check the floor

[Chalker]

Started a bathroom today, bounced on the floor and in more than one place it was terrible. So instead of taking traps up and fitting noggins ,i decided to lift the whole floor.
heres what I found!
no noggins at all.
no perimeter noggins.
two of the joists were nearly an inch from touching the sleeper wall.

Looks like some work tomorrow!

Sorry about the second pic. Wrong angle to show that its 20mm above the sleeper wall.

 

[Mr Tiler]

Brilliant example chalker thanks for sharing what do you plan to do to get the beams all sitting level on the sleeper wall? Cheers

Looks like two issues need to be addressed mrT
1, excessive bounce
2, floor possible not flat / level.

Ask yourself. How would you fix these two problems? I know it's hard as your only looking at pics, it's difficult to see exactly what's going on.

Few joist hangers.......couple of noggins. Job done. :smilewinkgrin:

 

[Mr Tiler]

Same as whitebeam but more than a couple of noggins lol. Also if the joists are too far out and shims can't be used it would be a case of bolting 2x4 to the existing joists but at the correct level and fixing timber to the 2x4's... All theory of course as I have no experience of levelling out a timber floor 😉 so please don't slate me lmao

 

[Chalker]

Thanks for the replies.
im going to run a perimeter nogging, then two rows of 4x 2 noggings going the length of the floor. All glued amd screwed. The sleeper walls are level, so I'm sure I can get the floor flat and level. Will have to do some packing on the sleeper walls, after making all the pipework alterations I've talked the customer into letting me fit 50mm kingspan between the joists, ( extra cost). Then fitting 22mm ply, glued and screwed ready for the aqua4ma wet room tray and floor panels.

thats in theory anyway.

Got to be something on here that'll do the job.

Might be a good option mate, but with sleeper walls already there , that's the fist option as its the most solid.

Im an Apprentice trained house mechanic, Ash. Plumbing is the easy bit.

Can't call it plumbing if it involves pushfit. Bit like giving a tiler self adhesive porcelain.

Here's this mornings work/ update.
wold have really liked to replace the joists, but I'm on a price and the joists go through into the hallway next to the bathroom.
1st pic shows the gap under one of the joists.
i cut some new packers for under the joists to level the floor and then ran a noggin round the outer edge. This was then secured to the dividing wall.
two other rows of noggins were fitted, one which will go down the centre of the 1st sheet of ply and one to support the ply edge.
the joists which will end up where the shower waste will go have been trimmed too.
have finished the pipework and drainage alterations so will be insulation and fitting plywood tomorrow . Got to get the ceiling boarded by lunchtime as the plasterer is coming!

 

[Mr Tiler]

brilliant stuff mate looks a lot neater and safer now!.. did the packers you mentioned go all around the perimeter of the room to bring it all up level? or just used to sit under the ones that were not quite sitting correctly? cheers
