I understand what an "H-Joint" installed floor pattern looks like (see below), but what is it that makes it not good? Is it that it just gives some people Creepy feelings (not Good) or does it come apart easier (also not Good) or what, I truly do not understand?

installed floor pattern from an earlier post (with no explanation other than pattern) Gary - Culling boards? and H-Joints?:

I believe it's purely aesthetics

So jeff, what you are saying is it could be a "Creepy feelings" thing.

Well I had a feeling that it might have evolved aesthetics so I Googled it and came up with the following:

From <edited by Admin: Poor website reference>

Oh my goodness. Spend enough time on that site and anybody is sure to be misguided. I had to remove the link source and comments because the site is and always has been the scourge of the internet when it comes to flooring information. They basically copy information from good informative websites (including one of my own), spin the words, and throw in a few ridiculous thoughts of their own so it looks original.

Total rubbish.

Jeff is correct.

Thank you I didn't even want to rebut it.

It is structural. It is not so important when you have a quality subfloor. But it is a good habit to avoid for those times you have to install over sleepers. Those joints create a weak spot where the floor can buckle down. So they are not as important now, but you can tell a floor guy has not been around awhile when you see alot of them.

If it is structural and sub-floor related, is brick pattern parquet okay if nailed down on a plywood subfloor using cleats?

I am DIYing my floor (900+ sq ft) and wanted to do a parquet diagonal basket weave. So I bought standard variable length oak bundles and cut them to exact sizes. I then tongue and groove the ends. But I ran into problems every time I change orientation of the boards -- there's always a few ends that won't butt due to the tongue and groove orientation. Furthermore, I can't nail down the wood because some section has the tongue side buried.

Tried other patterns (chevron, flat basket weave, etc) and whenever there is an orientation change, both problem exits.

To fix the problem, half of the wood should have been mirrored cut. Unfortunately, all my wood has been cut already.

My only solution now is to install a brick pattern. And yes, all the edges will be H-joint.

Is this possible? Or I risk problems in the future? My inside humidity fluctuates from 45% to 60%. Any comments?

It's not structural. Maybe in a laminate or floating wood, but not in nail down.

Designers pft!

I did an Abercrombe, with light and very dark vertical bamboo in a brick pattern as a gluedown last year.
