Reblocking is also referred to as Restumping. It is a process that involves either replacing or resetting damaged stumps on which a house sits. This is for houses in Melbourne that have a subfloor made of stumps. This process is crucial when the stumps settle due to soil movement.
Melbourne Reblocking can also be done when the existing wood stumps rot due to excessive moisture. An older house set to undergo major renovation can also be reblocked to ensure it can hold any extra strain. Restumping is a huge undertaking. If it is not done correctly, then you as well as your home may be in danger.
How Will I Know That My Home Needs Restumping?
Here are some indicators that your home may require restumping:
- Major cracks on the interior walls
- Bowed or uneven floors
- Cracks on the exterior brickwork
- Windows and doors that are not functioning properly
Houses are built differently and on different soil properties or conditions. Hence, different houses can show deterioration signs differently. However, if failed stumps are not repaired, then consequences will all be the same, either the structure will collapse partially or completely.
Although a structure can be reblocked partially, where only certain stumps need replacement, it is always risky to leave some stumps unchecked since some of them might be rotten without being noticed and the condition may deteriorate in future.
You would have to restump your home again. For instance, some stumps may be rotten from within the ground and this may not be noticed easily.
You can simply check the state of wooden stumps by digging into the ground for a depth of around 10cm and scratch the base of the stumps. If a stump gives easily to scratches, then it’s a sign that it is rotting and requires replacement before it crumbles.
Also check for water marks on the stump. If it has visible water marks on the surface above the ground, it means the stump has absorbed moisture. If at least 30 percent of the wooden stumps show signs of damage, then you should get all the stumps replaced.
The Restumping Process
Restumping starts with assessing the stumps that should be reset or replaced. This can be done by checking whether the floors are level. A level is used to check the evenness of the floors. Stumps are also checked for deterioration or movement.
Once this is done, the structure is slightly and gradually jacked up on the section where the stumps require replacement. Depending on the extent of movement or resettling, restumping may lead to issues such as tile damage, cracks in the plasterwork, and warping on the doorframes among such other issues.
Wood, Concrete, and Steel Stumps
Nowadays, restumping is mostly done using concrete or galvanized steel stumps. They are better than wood for they are not prone to the weaknesses demonstrated by wood.
For instance, concrete and galvanized steel do not warp like wood and they are not prone to attack by termites. Steel stumps can be adjusted onsite. This is beneficial for it can save effort and time during installation.
Although restumping is quite expensive, it is advisable to get it done by experts to ensure everything is done professionally and save your house from collapsing.
If done improperly, you may end up spending more money for another restumping project or the house may even collapse. Hence, have it done properly by a professional restumping company.
