In the video, a man is seen using a torch to repair a crack in a concrete surface. The man is wearing a blue shirt and black shorts, and he is holding the torch with his right hand. The torch is connected to a hose, which is presumably connected to a gas source. The man is standing on a concrete surface, and there is a building visible in the background. The man is using the torch to heat the crack in the concrete, and he appears to be applying a substance to the crack to fill it in. The video does not show the entire process, but it is clear that the man is using the torch to repair the crack.
