Wet crawlspace fix

Hi all,
So I'm trying to stop water welling up into a crawl space (raised foundation) after heavy rain (fortunately not too often in my climate). This looks to be beyond my ability, so I'm hiring contractors. The solution they proposed involves digging a trench around the house and ~1-2 feet below the foundation wall, then filling with concrete, to basically provide an additional barrier to stop subsurface water intrusion. See attached photos for an idea.

Does anyone have experience with that type of fix? Does it work? Any concern about damage to the foundation?

Thanks in advance!

Welcome to the forums!

Not my area of expertise but I'd think you'd be better off digging the trench [to footer depth], waterproofing the foundation and then installing drain tile and gravel to pipe the water away from the house.
