Shallow Vertical Groundbed: Sometimes due to unfavorable soil conditions, shallow horizontal groundbeds are preferred.

For underground structures requiring cathodic protection, the location and nature of the site where the anode is placed needs careful consideration. The location which is specifically prepared to house a single or a combination of anodes is called a groundbed.

Types of groundbeds are classified as:

• Shallow Vertical Groundbed:
  The individual or multiple anode groundbed resistances can be determined using Dwight formula or can be determined graphically
• Shallow Horizontal Groundbeds:
  Sometimes due to unfavorable soil conditions shallow horizontal groundbeds are preferred. Again earth resistances can be determined by calculation.
• Deep Well Groundbeds:
  Where soil resistivity at the surface are very high, a series of vertical anodes are sometimes installed in deep well groundbeds (up to 100 m and more deep).

1. Complete factory prefabrication,direct construction on site, quality assurance;
2. Convenient construction, greatly reducing the workload of installing anode ground beds;
3. High cost performance, reducing material costs while improving construction efficiency;
4. TC sealing system ensures that cables and anodes are well sealed ;
5. Both ends of the anode are connected with cables at the same time to avoid breakpoints;
6. Using reel packaging, small volume, can be directly laid.
