Underpinning Contractors Melbourne Macro Underpinning Melbourne is responsible for laying a solid foundation for your building to make it strong and sturdy. Any building in which brick veneer walls and concrete slabs are used loses its strength over a time period. When the alignment of the brick veneer loosens up, cracks start appearing in the slabs. For your safety it is crucial to cure this issue and resolve any underpinning related problem. We use heavy jacks to prop up any cracked or sinking slabs and then use concrete for brick alignment. This overall enhances the strength of the building. Restumping/Reblocking Melbourne Restumping/reblocking is somehow analogous to underpinning but there is one exception. In restumping, our experts will replace the whole stumps. We use jacks to dig out the foundation and then replace cracked stumps with new ones. In some cases this leads to minor damages to walls or floors but with Macro Underpinning you don’t have to worry about such issues. Our experts will take care of any damage done during restumping.
