The foam is designed for this and it will not expand or contract in future. The problem is what are they planning to do with the holes. I wonder why they drill on the wood. This probably not common practice.

Agreed on the holes. I am reminding them to properly let the concrete set in before seal them.

Nowadays still got wood door frame? Mine was fully metal

this is standard practice to inject expanding foam into hollow wood frame.

Ya mine still using wood.

Ok, good to know. Was abit skeptical before this.

Concrete and wood don't get along due to excessive moisture.

What would be the long term effect?

Door frame will warp or curl and the door will not close properly. Might need to do some trimming later. The rectification will be fugly.

Wrong info, the door frame is actually aluminium. So less worry on moisture and warping. However, the foam concrete doesn't solve the hoolow sound issue and now left owth unsighly holes (yet to be covered with putty and painted over)
