Melbourne is a city with more architectural wonders than what meets the eye. This is especially true below ground. If you’re a Melbourne resident or a fan of architecture, then it’s likely that you’ve heard about the term “underpinning melbourne”. Let’s first explore some of the causes for settlement and subsidence in the city’s buildings. Go here!
After a great party, you might find your living area a bit messy. Melbourne’s soil can look like a messy living room, after a geological party. Chatting with friends is a great way to break down the information.
Melbourne lies in a part of the world where soil loves to move. Here’s what we mean by soil movement. Changes in moisture levels can cause soils to expand (when wet) or shrink (when dry). Buildings can sink or tip due to this shifting dance floor. It could just be that the cracks in your walls are earth’s expression of “I have had too much fun!”
Melbourne is known for its leafy suburbs. Trees and plants sometimes give buildings an ‘hug” that is a little too tight. They can cause subsidence by removing moisture from soil.
History’s Weight (and modernity) Age of structure, and materials can have a significant impact. It is possible that older structures do not have as much foundation depth as modern ones. If you also add in the extra weight from additional floors or additions, the ground could protest.
There’s water everywhere: Leakages of water from pipes that are broken or drainage problems can erode the foundations. Water, water everywhere: Leakages from broken pipes or poor drainage can soften the ground around foundations. The result? This is like building a sandcastle on the beach. It’s like a wave coming and going down!
Mining and Excavation: Melbourne’s past has seen some mining. Unmanaged voids can result in ground instability. Coupled with today’s excavations to build infrastructure, you could be in for some serious ground problems.
