Add grout along base plate and concrete floor?

[Nilsanni]

In the garage, I have a sill with some form of EPDM rubber underneath, which lies between the sill and the concrete slab.
However, animals are coming in from outside and they seem to be entering under the sill.

Is it okay, from a construction standpoint, to apply a sealant along the sill/concrete on the inside?
I'm thinking of an acrylic sealant/building sealant that is elastic.

The slab is an insulated slab on ground.

This is how ChatGPT responded to the question.. But I'd like it confirmed by someone who knows!

"Absolutely, applying sealant on the inside between the sill and the floor is a good way to prevent insects from getting in. It also helps to improve the building's air-tightness and energy efficiency.

It's important to use a sealant that is elastic and suitable for the purpose, such as an acrylic or silicone-based sealant intended for construction. It's also a good idea to ensure that the surface is clean and dry before applying the sealant for the best results.

This step is quite common and recommended to avoid pest problems and to achieve a more airtight and durable construction."

Is it okay, construction-wise, to apply a sealant along the sill/concrete on the inside?

Yes

Maybe age-resistant tape is even better?
Put a strip around so it's attached with half on the sill and half on the floor.

Regular construction foil tape doesn't adhere well to concrete, it will come off after a while.
I would have used outdoor sealant.

But it also depends on how it looks from the outside. You don't want to trap any moisture coming from outside either.

No, this is exactly what I'm thinking too, that I don't want to trap any moisture or anything like that. But I do want to keep the little animals out since they seem to find ways in today.
What should I be checking for from the outside?
As far as I know, there is no sealant on the outside, only paneling.
