Melbourne's vibrant art scene, rich history and iconic coffee culture are not the only things that make it famous. This dynamic city is also plagued by a less-fun feature, foundation subsidence. Unaware of the danger, many homeowners are searching for solutions to underpinning in Melbourne. What is the cause of this drama underground? Unpacking the mystery is our goal! Visit our store.
1. The soil type and variations:
Melbourne is blessed with an array of different soil types due to its geographical diversity. Each soil responds to water differently, from clay areas to sand pockets. Clay soils can contract and expand more when they are wet. This leads to foundation problems.
2. Plants and Trees:
What person doesn't like a green suburb? Trees, particularly those with large root systems can drain significant amounts of moisture from the ground, which causes it to contract and dry up. A tree near your house could be damaging your foundation by its thirst.
3. Water Leakage:
Leaking pipes, particularly those near or under the foundation can cause the soil to soften. It can cause soil erosion, and over time create spaces where foundations can sink.
4. Poor Drainage:
Melbourne is prone to heavy rains, which means that houses need efficient drainage systems. Water can collect around the house's foundation and contaminate the soil if they are not installed. It could cause the soil to swell if it is clayey or even wash away if it is sandy or loamy.
5. Historic Ground Movement
It is possible that older parts of Melbourne have experienced ground movements over the years, due to either natural causes or past construction. These sites may be more susceptible to subsidence.
6. The foundation depth is insufficient
Some foundations may not have been drilled deep enough when they were constructed. As the soil changes over time, these foundations may become unsteady and sink.
Being aware is only half the battle. Early detection of these factors and prompt intervention can be achieved by recognizing them. Although underpinning can be an effective solution for foundation subsidence in some cases, homeowners should also take preventative measures. It can be a huge difference to regularly inspect your house for cracks and ensure effective drainage. You may also want to consult with an expert before you plant large trees.
