A year ago, I bought materials to build a deck. Pressure-treated 120-rule and Siberian larch 21x95. The deck was never built, and the wood has been lying under a tarp instead. Now I was thinking of moving it into a shed and wondering if the planks can be salvaged. They are very damp and some of the larch has cracked. They haven't warped. Is it possible to work with this or will it just warp and crack later? How should I stack it in the shed, battens between each layer and straps? Best regards
I don't think there are any problems, lärk can withstand quite a bit... That they've cracked? They would have anyway... I have many that have cracked...
The läken I have as deck swells up like a sponge as soon as it rains for a period... There are gaps of 5 mm today, by autumn there won't be even a single mm.
If it were to age and get a natural gray tone, you just scrub it with something like soap when it's done and let the sun and rain do their job. If you were to oil it or something, it might be difficult to make it look nice without having to sand it, etc.
Tightening it with straps if it's läkt sounds wise, so you've done something to prevent it from warping too much... But I can say that out of the hundreds of boards I've bought, not many have been straight... Too much demand has made it seem like they're cutting down everything they can find...

No problem using the timber, if it feels damp when you touch it, you should dry it outside before putting it in the shed. Level some studs on the ground (preferably 10-20cm above the ground) with a long straight edge, place them 1m apart, stack loosely with 5cm space between each board, place 1" battens before the next layer. If you have some old corrugated sheet, place it over, otherwise, you can throw on the tarp you have, just don't pull it down on the sides, it must be able to blow straight through. Let it sit until there have been a few dry days in a row, then you can do the same stacking inside the shed, though you don't need to put a "roof" on it then 
Lovely, thanks for all the answers, now they are in the boden anyway.

Do not bring them indoors, but let them have outdoor temperature and air. Otherwise, there is a significant risk that they will start warping. Your shed might just be a roof with uninsulated walls.
I usually stack the timber and cover it outdoors for half a year before using it. Any bad boards that have cracked a lot or become warped can be avoided. I also do this with the indoor timber instead of shocking it with indoor dryness and heat.

Pressure-treated timber often has a warranty against rot damage, even when it is buried. I have stored it outdoors under a tarp, with straps, but without an air gap in between, to minimize the risk of warping. However, I have no personal experience with storing pressure-treated timber.
