Casting raised base of Leca?

[Byggaren1974]

Hi, I have purchased a garage kit and am casting a concrete slab on 300mm edge elements, a smooth slab that is. Now I am considering raising the garage with a base of 250mm leca blocks. I talked to the garage manufacturer about this, but they said it wasn't possible because leca was too porous to attach the garage to. Is this really true or can I just cast a leca base anyway? If not, what other blocks can be fixed instead?
The garage is an insulated wooden building with a single-pitch roof and roof tiles, length 7.3m, width 5m, wall height 2.53m, outer total height 4.2m, 14-degree roof pitch. No underfloor heating.

Works excellently with Lecablock and it is probably the most common solution.

Perfect, then I know! Is it just because the manufacturer of the garage wants to protect themselves against potential collapse of the building that they say it can't be done?

Hi, did you use leca for the garage? Did you reinforce the leca? Vertically and/or horizontally? I’m considering laying a row of leca and am thinking about the reinforcement...

I bricked a row of 200mm high lecablock as a base around the concrete slab. No reinforcement was used then. I then screwed the wall segments to the leca.

Okay! No cracks or anything between the stones? Did you also apply mortar between the stones (joint)? It would definitely be easiest to skip the reinforcement.

No cracks at all, it's lecablocks that fit into each other. Had some problems with getting the mortar to adhere between the stones, so it ended up being illbruck's stone adhesive between the blocks instead. This was done last summer and so far there haven't been any damages, despite larger amounts of snow on the roof. Bought the lecablocks at Bygma.

sounds promising, maybe I'll dare to go without reinforcement then. Thanks for the info!

Yes, that should be enough if you're going to lay a row of bricks.

It was the first time I had ever done any kind of masonry work.
