springy kitchen floor problem - sleeper wall necessary


Postby MELDREW » Wed Mar 16, 2011 11:13 pm

Hi,
new to this as of tonight so apologies if this has already been covered/answered.
My problem is probably my own fault - when I extended our bungalow 10 years ago - I didn't think a sleeper wall was necessary on the new extension (a span of roughly 3.4 metres)
The joists were 8x2 - and my thinking was this would therefore not need a sleeper wall.
However, my father-in-law said it would require one - and sad to say - I have been putting up with a bit of a springy/bouncy floor since.
I want to put laminate flooring down - and wondered if I should do anything to support the joists beforehand (will be a bit of a workup lifting the floor) - or is there an easier way (someone suggested unscrewing the T&G flooring sheets and glueing them before rescrewing them? thanks :(

MELDREW,
Lift the boards and fit a sleeper wall.

You might get away with cutting 2 or 3 x 18" holes next to the main joist that has movement & putting 4x2's down on to some flag stones placed on the sub floor. But this will depend on the sub floors material & how stable it is.

Hi

Install a 225x75mm spliter/binder under the existing joist's half way along in the opposite direction.Knock out and sit on inside skin 100mm bearing.Rap the ends with dpm and allow a void under the new joist.

Bye

Okay - thanks to all for your advice - looks like there isn't an easy way round it - so will consider the suggested options.
