Just like icing on the top of a cake, mud pumping is the final layer of work in foundation repair. If we have a contract for a repair job, for a levelling task or we have done some restorative work on the foundations of a building, often the soil consistency below the building would have changed. This is normal because buildings are heavy! If our work has caused even a tiny shift in the weight of the building, then it is natural to assume that the ground beneath it would have been affected by this weight shift. Now, normally, this isn’t something you would tend to notice because foundational structures, like concrete slabs, plug the gap between a building and the ground. But, if you image that the soil consistency has changed, then it is good practice to assume that there might have been a weakening of the foundation at some point.
