We offer homeowners in Melbourne a new underpinning method which is faster, less messy, and much more efficient than the traditional method. In this method, our contractors use advanced, new age equipment to inject the old concrete stumps with re-strengthening material. The material not only fills the cracks that would have developed in the stumps, it also expands the foundation which can lift the subsided concrete slabs from the soil without the need of any external support.
