The Basics of Underpinning and Reblocking
Underpinning is a technique that is used to stabilize the foundation of buildings, especially those that are constructed using concrete. It is a very complex and intricate process. This is why you should be sure to hire a qualified and experienced underpinning contractor. They can be very helpful in identifying the right restumping underpinning solution for your particular needs.
The underpinning process involves using heavy jacks to support the structure. This strategy works by bolstering fragile pillars and beams at the foundation. When the pillars and beams begin to crack, the structure begins to sink. If this is not dealt with, the damage can become worse and you could end up with a house that is dangerous to live in.
Reblocking is another technique that is utilized to fix the foundation. Reblocking is the process of removing damaged or rotting stumps and replacing them with new ones. You can choose between wood, steel, or concrete to replace the stumps. Wood is not a very good choice, as it is prone to moisture and termite damage. Steel and concrete are both strong and durable.
Restumping is a major home renovation project. You must take the time to evaluate your stumps to ensure they are not damaged or rotten. A good underpinning service provider will use a combination of heavy jacks and concrete to strengthen your foundation.
The oldest method of underpinning is the concrete square method. It is an expensive, and time-consuming process. This is because it requires a lot of manual work. However, the benefits of underpinning using this method are worth it. Using a concrete pad at the base of the restumping job provides optimal protection against footing settlement.
Reblocking is a more effective option for houses built with timber or brick veneer walls. Timber is the least stable and rots quickly. Concrete and metal are more resistant to termites and do not rot. Therefore, these are the materials most recommended for restumping.
Another popular technique is the "jack and pack" method. During this process, concrete stumps are packed into place using a combination of high density plastic packers and bottle jacks. These jacks are then pumped with cement to give them extra stability.
If you decide to have a house reblockes, be sure to check the house for signs of salt damp. Salt damp is excess moisture that collects around the foundation. Signs include bubbly paint, gassy plaster, and a pungent odor. In addition, the walls can start to crack after reblocking.
Besides the usual suspects like water leaks, cracked walls, and leaking taps, you should also check the floors of your house. If they are uneven, you may need to consider relevelling the floors. Also, if your doors and windows are malfunctioning, you might need to consider underpinning.
Lastly, remember to get a professional inspection of your house before purchasing it. Even if the price is reasonable, it is a big investment. Whether you are building a new home or renovating an existing one, you should invest in underpinning and restumping. Both of these are important to the overall stability of your home.
