You have to eventually replace the stumps that reinforce your house as they began rotted and defective. If the floors of your house start to sag or fluctuate, and the door house was no longer opened or closed smoothly. The problem could not be those items; it could be an indication that you have to replace your house stumps. Stumps are generally made of timber as they are the least expensive ones with concrete being the strongest.
What is Restumping?
Restumping is a process in which you have to reset or replace the stumps on your house. This process mainly requires when the stump of your house become rotted and defective due to soil moisture. If your house is old and you are considering renovations, then it is better to restump your house first because of the added strain on the house structure.
Keep in mind that restumping any house is a massive proposition; it could further damage your house if that is not worked correctly.
Following are the step-by-step process of Restumping a house:
Step 1: Firstly, everything that’s around your house needs to be cleared, including plinth boards.
Step 2: Next, in the cleanup stage, all the rubbish and obstacles placed under your house will be removed.
Step 3: Before starting any restumping work, it is essential to make the house safe for both the house owners and the workers who will be doing the Restumping work. To achieve this, the workers will put on jacks that will reinforce your house during the Restumping process.
Step 4: Once all the safety measures have taken into account and jacks are in place; it is time to begin the restumping work. The workers will then start to knock out the old red gum stumps.
Step 5: Once all the red gum stumps are cleared, a hole is drilled in the same place, and the soil is taken out from that hole. The minimum depth of soil should be 600mm under the load-bearing walls and a minimum of 500mm under the floor without any weight.
Step 6: Once all the red gums have been successfully removed, the local council or a private surveyor will then conduct an inspection. At this moment, the house is reinforced by the jacks only.
Step 7: Once the inspection has been completed and the necessary approvals obtained from the concerned authorities, the workers will then begin to computer level your house. It is an extremely accurate process and gives you desired results.
Step 8: After that, the workers will then start to measure the holes drilled a while ago to place the right size concrete stumps in it. Once the concrete stumps arrive, it will then be handed over to the bearers so they can start concreting.
Step 9: The final stages of Restumping your house starts with the ordering of concretes. The strength of concretes is 32mpa so the ordered concrete must be at 32mpa. Anything less than that is not ideal for restumping. It is important to have the concretes used in the restumping process is in good and stable condition.
Step 10: A pump truck is required to pump the concretes through under the house so that they reach every single hole. Professional stumping experts always leave a room of minimum 200mm to 250mm under the stumps to ensure enough concrete is there along with a strong base. It will reinforce the concrete stumps, which in turn supports the overall weight of your house.
Step 11: While the concreting process is taking place, every single stump placed outside has an evaluated pine in the holes along with a stump. This is because when the plinth boards which will be put on later, can be nailed to those pines and hold the plinth boards up.
Step 12: Once the concrete stumps are put in place, give the concretes a couple of days to settle. After 2 – 3 days, when the concretes are fully settled, the workers return to remove the jacks that were put forth to reinforce your house initially. Then they backfill all the holes they drilled with soil that was taken out in the process. Because of this reason, most professional stumpers don’t concrete the houses right through to the top.
Once everything is complete, the workers will then put new plinth boards if requested by the house owner.
