There are two types of underpinning: restumping and restumping. This depends on the footing system your house was built upon. If a house was built on a suspended floor, restumping is necessary. Concrete slabs require underpinning. Concrete slabs can also be used for footings, but stumps are not necessary.
How can I tell if my house was built with a suspended floor?
If crawl space is visible underneath your floors, it's possible that your house was built on suspended floors. If your house was built on stumps, duct heating and vacuum systems could be indicators. If you look closely, you might notice that the floor is higher than its counterpart on the ground. This means that your property was built on stumps.
Concrete slabs can be seen if you can see between the floors. Bendigo Restumping will repair cracks in walls, uneven floors and difficult opening windows and doors.
What causes Stumps' Decay?
Timber stumps may crack over time in areas with high heat or prolonged drought. Heat and dryness can cause cracking. These conditions can lead to stump movement, which can result in foundation weakness.
Termites and other insects can chew through timber stumps, which can lead to serious problems. They are unlikely to cause damage to your property. These insects are more likely to be found in this area. Pest control is a way to prevent the destruction of your timber stumps by insects.
No matter the material of your stumps, they will still be susceptible to wear and tear. No matter what material your stumps are made of, whether they're steel, concrete or timber, eventually they will deteriorate and lose their structural integrity. The longevity of stumps will depend on how well they can resist concrete cancer and rust. In ideal conditions, stumps can last up to 80 years. Regular inspections are important in order to prevent any major damage.
Wet soil will cause stumps to fail. It is important to address drainage issues and plumbing problems near your home. Your stumps could have become darkened due to too much soil. This could eventually lead you to subsidence.
Subsidence is when the foundation cannot support the weight of the person. This can be caused by excessive moisture. This can happen to plants that are water-hungry. They can absorb moisture from the soil below them. This can cause problems if a house is built on land that was once used for quarrying. Clay soils can cause subsidence. It doesn't matter what kind of soil you use.
Your stumps' stability can be affected by the soil type and amount of moisture in your region. Reblocking is required for many homes made with reactive clay and fill. Reblocking foundations constructed from reactive soil is important because they can expand and contract according to the moisture.
