Impregnated post not fully pressed through

[kitco]

Bought impregnated 70x70 posts to build a fence, and when I cut the first piece I see that the impregnation hasn't penetrated the entire wood. Is it supposed to be like this or is only the outside impregnated?

I assume that mistakes can happen but everything I've cut up shows varying penetration... where it doesn't penetrate, it's not needed.

Generally speaking, it must be really poor wood if you get 100% penetration, and if it's good, you get very little...

The outer is probably sapwood and the inner is likely heartwood that doesn't take/need impregnation...

As Arne TW writes.

The impregnation fluid penetrates where it can (=where it is needed). In the denser and more resin-rich core, it is not needed.

I am definitely no expert on this but I think it looks strange. On the wood I have handled, it has always penetrated a little on all sides, in heartwood very little but still fully visible.

Okay, will it survive in a stolpspjut in this condition then?

If the area where the impregnation did not reach had had extremely dense annual rings and been dark with resin, I would have understood if the liquid didn't reach there for the aforementioned reasons. Now the difference in annual rings and color is so small that I think it looks crazy. Especially when there's almost no penetration on essentially two sides. It basically looks like the wood has been showered with impregnation liquid without pressure.

Yes.
