Underpinning can help a home or business maintain a solid foundation, or correct structural problems. There are several methods used to perform this work, and each has its own advantages and disadvantages. The first method is mass concrete underpinning. This involves excavating the soil beneath a building’s foundation and pouring concrete in its place. The mass concrete is usually poured in squares, as determined by an engineer. This method is a good choice for foundations that have a relatively shallow depth, as long as the existing structure stretches over the underpinning pits.
Underpinning can improve the structural integrity of a house’s foundation, as well as extend its depth. It is often performed when the existing foundation is too shallow, or when the structure has developed cracks in its walls. It is also necessary to perform this work when work on the house would otherwise cause the structure to shift. Underpinning is also useful when it’s necessary to add additional floors to a home, or when the existing foundation has collapsed.
Underpinning is an excellent way to extend the foundation and distribute the weight of the building more evenly. It is often used in conjunction with stumps, which are hollow steel or timber poles driven into the ground. Aside from stumps, underpinning can also use piles such as steel screw piles and timber piles. Usually, underpinning is done on slab on ground foundations, but it can also be done on other types of foundations.
When underpinning is necessary, it’s important to consult a professional contractor. This contractor will be able to perform an in-depth assessment of the structure of your home or building. And they will have the specialized equipment necessary for underpinning projects. For this reason, underpinning should be considered a specialty construction.
Another important aspect to remember is that underpinning is required by building regulations. Underpinning must ensure that a building is stable and that sewers and drains are not damaged. The process can also ensure that the structure’s foundation remains intact as it continues to grow.
Underpinning is a costly and disruptive process that can cause havoc with a home’s environment. Depending on how much movement the house is experiencing, underpinning may be necessary. The process involves strengthening the foundation with concrete or steel footings. This method requires a temporary solution, and it’s not suitable for every type of ground.
Underpinning is necessary whenever you’re planning to add a storey to your house. The existing foundation is no longer strong enough to support the additional weight of the building. This is especially important when adding an additional storey to an existing home. If the foundations are too weak to support the extra weight, underpinning may be necessary to stabilize the structure.
