viga de reforço cheia sem quebrar laje

In this video I show a way to fill a reinforcement beam without breaking the slab by filling it from below without having to dirty the top of the house. I also have a video of filling from above the broken slab. However, in this service the proposal was to use a different technique that fits in some occasions (so an iron beam is one type of service and wedging by brick is another. This form of the video is a technique created by me).
