House stumps fail because of rot, corrosion, and rust. Timber stumps weaken as they soak up moisture, leading to rot. Concrete stumps face corrosion, while steel ones rust, especially in wet areas.
If you notice your house stumps deteriorating, it’s wise to seek advice from a Sunbury restumping expert. Doing so will help you avoid issues that could get worse over time.
In this article, we’ll explore the reasons behind house stump failure, focusing on timber, concrete, and steel stumps.
What Causes House Stumps to Fail?
Timber house stumps fail because of rot, concrete stumps to corrosion, and steel stumps to rust. Let’s check out each one below for more details.
Why Timber Stumps Fail
Timber stumps can fail because of rot caused by too much moisture. When timber absorbs water, it starts to decay, making it weak and unstable. Regular checks are important to catch any rot early and fix it before it causes serious problems.
Additionally, timber stumps may also fail if they are attacked by pests such as termites. This can further weaken the wood and compromise the structural integrity of the stumps.
Why Concrete Stumps Fail
Concrete stumps can fail because of corrosion, especially in damp and acidic soil. Over time, water and chemicals can seep into the concrete, making it weaker. Proper installation and using good-quality materials can help prevent this.
Furthermore, concrete stumps may also crack or shift due to ground movement or inadequate support, leading to structural instability and failure.
Why Steel Stumps Fail
Steel stumps can fail because of rust, especially in wet areas. When steel rusts, it becomes weaker and less reliable. Regular inspections and protective coatings can help prevent rust and keep steel stumps strong. Knowing the right types of footings for each material can also make a big difference in preventing failure.
Moreover, steel stumps may corrode faster in coastal areas due to saltwater exposure, requiring extra maintenance to ensure their longevity.
Lifespan of Different Types of House Stumps
The following are the lifespans of stumps according to material:
Lifespan of Timber House Stumps
Timber House stumps typically last between 20 to 40 years. Timber stumps have the shortest life spans of the three types of stumps as they are more prone to rot, particularly in damp areas.
Lifespan of Concrete House Stumps
Concrete stumps will typically last 50 years or longer. While they are less susceptible to decay, their lifespan will be reduced if the environment is damp and the internal steel begins to corrode. Keeping an eye out for such issues can ensure their longevity.
Lifespan of Steel House Stumps
Steel house stumps, when galvanised, will typically last around 70 years or more. However, to reach this impressive age, they require consistent upkeep and protection against rust, particularly in humid environments or coastal regions where salt in the air accelerates corrosion. Regular maintenance efforts can greatly prolong their lifespan.
