In civil engineering, concrete raising is a process which attempts to adjust an uneven concrete surface by slightly raising the concrete level beneath it, thereby correcting an unbalanced surface. Raising concrete levels is a fairly simple process, but one that many do not think about until it is too late to do anything about it. Concrete is composed primarily of Portland cement, sand, and water. When mixed together, Portland cement forms a sort of paste with calcium carbonate and water. Once this mixture is mixed and poured into a mold, it will harden and become solid. In order for this new material to be raised to a desired height, it is first “raised” by using steel rods that have been inserted into the mold. Have a look at Concrete Raising.
While this process sounds relatively simple, it can actually get quite complicated. First of all, there are a variety of different methods that can be used for concrete raising, and these range from the very simple, such as pouring concrete into a small hole and letting the concrete sit, to the extremely complex, such as pouring concrete through a series of holes and raising each layer of concrete separately. Some of these molds may be manually operated, while others may be electronically operated. There are also a wide range of different concrete products used for concrete raising, including: steel rods, concrete wedges, raised edge forms, and concrete columns. All of these products and processes can have their differences, but they also have similarities, such as:
Concrete raising is a necessary and important process for several reasons. By placing steel rods or other forms of support under each level of concrete, buildings can be made stronger and more resistant to natural disasters such as earthquakes and flooding. Also, raising the concrete level of a building can make it easier for a building to withstand damage from fire. Finally, by making sure that the concrete is properly raised, the overall aesthetic appearance of the area where the concrete is located can be improved.
