Foundation grounding is a very good method for making a complete grounding system. At the same time, it is very cheap. It must be remembered that the foundation itself plays an important role not only for the foundation of the building, but also for the entire electrical installation. For this reason, it is worth choosing a foundation grounding, which provides maximum safety. It is worth learning how to make a foundation grounding.

How to properly perform foundation grounding?
Foundation earthing is most often a system of interconnected wires that are placed in the concrete that is the foundation of a given building. It is important to remember that the concrete used for foundations should have a good resistivity of 200. Of course, it is also necessary to select the right materials that are resistant to corrosion and have maximum strength. The elements are cast in concrete, as are the reinforcing bars. In order for the entire lightning protection system to function properly, the foundation earthing must be properly made. This provides protection against electric shock. Its construction does not require additional earthworks, which also saves a lot of time.
The grounding elements are installed during construction work, after which the foundations are poured. Of course, the connections should be checked by an electrician. Photographic and descriptive documentation should also be used. Remember that the foundation must have reliable electrical contact with the ground. What does the word "reliable" mean here? This can be explained by the fact that it must be sufficient and durable for the entire time that the building is intended to be used. You can also use a natural foundation grounding, where the elements are connected with a tie wire. It is closed in a steel ring using a round bar or flat bar. Such a durable connection with clamps ensures effective electrical conductivity for many years.
What are the types of grounding in a lightning protection installation?
We distinguish between protective grounding, grounding in the lightning protection and electrical installation, and grounding of the telecommunications installation. In the former, integrated grounding systems are used, while in the grounding of the electrical installation, a third wire is used, which runs next to the phase and neutral wire. At the same time, electrical sockets are combined into one system.
It is the end of the grounding. It must also be remembered that it must be buried to an appropriate depth so that the electric charge discharged into the ground does not pose a threat. The grounding of the telecommunications installation is also important, which is performed in order to ensure the proper operation of teleenergy devices that are connected to the distribution network. It protects the low-voltage network from the potential effects of high voltage.
Ring and vertical earthing in an existing building
If no earthing was made during construction, it can be made in the existing building. In this case, only a ring earthing and a vertical earthing can be used. The first one is made using a hot-dip galvanized steel tape. It must be buried to a depth of at least 0.5 m. At the same time, the excavation itself must be about 1 meter away from the foundation. If the distance were shorter, the stability of the building could be impaired.
Such an earthing system should be a closed system. In addition, the excavation should be deeper if it is also to provide surge protection. On the other hand, the vertical earthing system should be driven vertically into the ground, at least 3 meters deep. You need to choose a place where humidity is maintained at a constant level. At the same time, the distance between the electrodes should be the length of a rod driven into the ground. They are made of pipes or specially prepared rods.
Materials for making the grounding are available at the Onninen installation wholesaler
In the Onninen installation wholesaler you can choose materials for making an earthing rod from the manufacturer Elko-Bis . The Elko-Bis complete 3-meter OC earthing rod is worth attention. It is made of strong and reliable materials. It is worth knowing that its length can be increased, but also the effectiveness of the earthing can be improved. It consists of a pointed pin, an extension and an earthing connector.
You can also choose the Elko-Bis 3-meter ELKONOMIC fi16 hot-dip galvanized complete grounding rod . In this case, you need to know that it provides stable and effective grounding. It will work well for both electrical and lightning protection installations. Because it is made of galvanized steel, it is extremely durable, resistant to corrosion and mechanical damage.
A good choice may also be the Elko-Bis ELKONOMIC 1.5-meter fi20 grounding rod , which has similar properties. It is extremely solid and durable. It allows for effective grounding, while ensuring the stability of the installation.
