Odd my builder and the posi-joist manufacturer both are blaming the abuse the egger boards took from 6 months of bad weather as being the source of the floor movement/bounce. While Egger themselves remain adamant their product would be fine.

TonyT Posted February 13, 2021 Share Posted February 13, 2021 Egger instructions are about 60 days without protection from memory, so would agree this would void the manufacturers warranty as the install instructions haven’t been followed.

TonyT Posted February 13, 2021 Share Posted February 13, 2021 I agree with lots that have posted that the minimum spec and poor installation practices will generally result in poor outcomes. Majority of trades need supervision or will take the path of least resistance. personally I over engineer critical parts of the build that would give me grief, but then I’ve worked in the game for 30 years so have seen the failings before.

While it certainly gives Egger a get out, they seem unfazed and suggested their product will still be fine. Have to agree as three of the rooms where not exposed to extreme weather and yet still are suffering floor bounce/flex. Link to comment Share on other sites More sharing options...
TonyT Posted February 15, 2021 Share Posted February 15, 2021 Combination of poor installation practices equalling non satisfactory outcome. It happens in every trade Link to comment Share on other sites More sharing options...

I think from memory egger warranty 45 days exposed to weather. All exposed edges should have been brushed with the same foaming glue as well. If you know you wont be getting watertight in that time don't put the floor down. With your builder on that one. As for bounce, who specified the joists ? Struct eng ? Was the egger fitted correctly and noggins used where ends not hitting joists etc ? Was it screwed every 150mm ?

trialuser Posted February 21, 2021 Share Posted February 21, 2021 Egger specifically don't want it screwed every 150mm. Used to be first row only, now seems it can be first row only or optionally a few other fixings at 1200mm Link to comment Share on other sites More sharing options...

All ends landed on a truss or noggin. Link to comment Share on other sites More sharing options...

You tuck the next board into the previous and THEN screw the leading edge of the previous board, not before. To be done with the glue wet, not left an then 'come back to it'. 1 Link to comment Share on other sites More sharing options...

Not difficult at all, done it on every floor I've ever laid. You just need to get a wiggle on, and lay each row into each other with the glue still wet. Most rooms are leas than 7m so less than 4 boards long. Many ways to skin a cat though. Poor cats Link to comment Share on other sites More sharing options...

Nickfromwales Posted February 21, 2021 Share Posted February 21, 2021 Length of longest run? On a long run, eg 7 or 8 boards long ( @2.4m per board x8 would allow for a 19m run ) needs at least two people on it. Still easy to lay wet on wet. I understand just fine, and have been laying these types of floors for a 1/4 century. If the job needs more hands to the pump to execute it correctly, then that is what I applied. Never had a single squeak from a single floor, ever. Glad that your method worked, also. Link to comment Share on other sites More sharing options...
