When you see cracks like this and they are directly under the central beam of the house, we know right away that it is important to look at whether the structure is reached or not. In this situation, we will take laser surveys to find out if the house has drowned. If so, we will have to pin it so that it does not collapse. If not, we will inject this crack with highly structural products and reinforce it on two sides with several stabilizing steel plates. Some cracks need a little more attention than others!
