Hello!

I am planning a garage construction before a cottage build in the future and I'm pondering how to proceed. This will be my first construction project, and I'm wondering how to easily get an elevated plinth during slab casting. I've seen edge elements being sold where a small form plate protrudes from the element to create a plinth. However, these seem somewhat expensive and a regular L-element seems reasonable.

I am attaching a drawing where I am considering casting the plinth after the slab has cured, but allowing the reinforcement to continue up from the slab (positioning and distance for reinforcement not yet figured out!).
Does this seem like a sensible solution, or will the strength be drastically affected since the entire wall and roof load will rest on top?
And is it possible to seal from the inside in a reasonable and durable way, using a sealant and painting? To avoid moisture intrusion when, for example, washing the floor inside.

Thank you very much in advance.

Best regards, Hampus

No problem casting that foundation later as you mentioned.
Wow, what a wall you have for a garage. Do you have too much money left over?
 
Okay, great, then I don't have to dwell on it anymore, thanks for your answer! I'm somewhat inexperienced in casting specifically.. It's going to be an energy-efficient mechanic garage in Norrland, so it's important to wrap the darn thing in double socks ;)
