Suitability. Does it work without any issues

3_Fall,

That Blanke Permat looks an interesting product, but seems hella expensive next to Ditra?

That’s because they’re completely different products.
And have different functions.

Now you have what you have in terms of the floor timbers we need to ensure that what ever is done now works for you and is the best and most efficient remedy so that you can get the tiles down and be confident that the floor is sound and tiles will be there for a long time happily It’s best to get this spot on now.

 

[Deyna]

acaciaguy I agree!

I've got the original timbers I removed here still, which are the same size and in decent condition (I think they are about 18 years old)

There isn't much space in the void (between 8" and 10") and certainly no easy access without taking the entire floor up so maybe putting down more sleepers is out of the question for now.

Other solutions for supporting mid span without brickwork but some limited access. This is an old house so I'd rather not hang anything new off the existing internal walls so it'll need to be freestanding...

I could use the old 4x2s as sisters, or I could grab a few 6x2s and notch around the sleeper. The "4x4s" in the middle are solid for the span so I doubt these need tinkering with. As I said, M12 bots at 500 centers with 50mm Sabrefix timber connectors.

You wouldn’t tend to add sleepers afterwards. Considering a sleeper wall is constructed, then S&C, then DPC then more S&C and then a section of 4” x 2” on its side which is then screwed/nailed into from the joists above- I can’t see how adding a sleeper wall would work easily after the joists are down.

 

[acaciaguy]

I agree. Joists are down and it’s going to be dificult to get underneath

Agreed, if it were a clean slate then different story! I've got plenty of time, but at least I can weigh up the options of making this installation tile suitable.

Take noggins out and double up the 4 x 2. It’s fairly simple and cheap. Where are you getting timber from locally

BPS normally in Leam. No particular reason other than locality. Theres a TP and an MK nearby as well.

I'd leave the perimeter noggins and joint supports in place. I wont be able to span the same length as I have UFH pipes in the way so I'll have to come up maybe 4 inches short.

Bps are great. Don’t use anyone else

I will go and read up. Looks like same sort of height increase so maybe a more suitable product for this substrate, and use Ditra over the concrete.

Always had good prices/service/delivery. Occasionally get the odd bit of ropey timber but its not often.

 

[acaciaguy]

I get all my materials from them when I need that kind of thing

Wait a minute. Where do you have Wet UFH?
