What to attach a stud in Lecablock?

[messijah]

Hi! I'm working on building the deck and need to attach the ledger board to the house. It turned out the foundation is built of lecablock, and the expansion bolts I tested didn't work well at all. Is there something else good for securing the ledger board in place? Maybe a good wall plug? The board is 45mm, so I would probably need screws and plugs just over 100mm long.

I have successfully used these for similar applications:

Okay, thanks for the tip! I'll buy some and see if they last

There are probably also nice leca screws today. Not something I've used myself but worth checking out maybe.

Lecaskruv is as solid as a rock!

Biltema's chemical anchor will probably work as well if the screws don't work, but lecaskruv certainly works

Last spring, I installed an 8m support beam in the foundation, which was made of leca. Initially, I tried using facade plugs, but wasn't completely satisfied. 140mm lecaskruv worked better; every screw tightened incredibly well!

I drove on hiltis. They pulled really well.

Fischer façade plug 135 mm works

What do you think about these? It says they work in lecablock, but does anyone have experience?

The advertisement promises a lot, maybe worth trying.

I tested them in my lecablocks, didn't draw anything :/

 

[messijah]

The ones I asked about or the ones andy78 recommended?

Lexaskruv is definitely the best for the application, as long as you don't overtighten. Fasadplugg work if you choose a quality model and drill the right size. The ones in the images from byggmax above resemble spikplugg in appearance.

I have used ESSVE lättbetongskruv with good results. No pre-drilling is required, possibly at the ends of the board. It's important to stop tightening when the screw has bottomed out. Continuing to do so will damage the fastening.
