Frost Protection for Slab
Frost Protection for Slab
(OP)
I'm not the original Engineer this detail was already done but we have similar foundation.
I have questions with the way the slab/grade beam was detailed for frost protection.
The grade beam is ok because it's below frost depth.
The slab is not connected to grade beam, it has isolation joint.
Is the slab protected against frost in this detail shown below.

Outside, unless the joint was sealed, I would say no, but inside, yes.

soil report recommend, "for slabs with turned down walls extending below the frost depth, no outside wall treatment is required"
my understanding with that though is slab needs to be doweled to wall/grade beam?
anyway, what's the best way to correct the detail.

I guess this detail is good.
It has a grade beam/wall below frost depth and a slab with 12" of non-frost susceptible material.

I recommend SEI/ASCE 32-01 Design and Construction of Frost-Protected Shallow Foundations. They have a situation where you have a slab on grade in an unheated building with foundation walls.
