The strength of a building's foundation is what determines its structural integrity. When the right foundation structures are used, a house can weather many storms and stand firm for many years. On the other hand, if the foundation is made using the wrong material, symptoms such as cracks on the walls, doors that won't close, separation of walls and many other indicators of weakness. Helical steel piles are famous for both residential and commercial constructions. Here are three main reasons to consider helical piles.
1. Ease of installation
Steel helical piles are easier to install than concrete because they do not need digging out or setting. The speed of installation is also enhanced by the fact that you do not have to excavate the soil around the structure whose foundation you are reinforcing to install the piles. Then, once the piles have been fixed, they do not need time to cure, and you can build on them immediately. These three factors make steel helical piles very easy to install.
2. Minimal invasion
Steel helical piles leave a minimal footprint after installation. You can have them installed in restricted places such as close to other buildings because you do not need extra space to keep them stable. Their design is flexible and depends on the specifications of your project concerning the soil type and load bearing needs. The piles also leave a minimal impact on the environment, when compared to materials like concrete. The installation process is done with minimal vibration, which makes your construction site minimally disruptive to the surroundings.
3. All-year installation
One limitation that concrete has as a foundation material is that it cannot be installed when the weather is cold. Concrete installation during rainy weather also slows down the curing process and might even affect the strength of the resultant structure. Steel helical piles, on the other hand, can be installed anywhere and during any season of the year. The piles can also be easily installed on any ground from the soft ground to rocky soil and even clay, without having to worry about the strength of the resulting structure.
Steel helical piles are therefore the best for underpinning and even for first-time construction. The essential thing to remember in dealing with them is always to consult a competent underpinning contractor. The piling contractors will inspect your foundation, figure out the weaknesses and advise on the best underpinning material to use.
