1st example

Conditions:

• Wall up to 1 meter thick
  Bare ground
  Foundation and ground on an equal level

Application of electrodes:

• Gridded anode outside above the ground
• Rodded cathode outside in the ground

2nd example

Conditions:

• Wall up to 1 meter thick
  Bare ground
  Ground on a higher level than foundation

Application of electrodes:

• Gridded anode outside above the ground
• Rodded cathode outside in the ground

3rd example

Conditions:

• Wall up to 5 meters thick as part of a permanent joint
  

Application of electrodes:

• Gridded anode inside above the foundation
• Rodded cathode outside in the ground

4th example

Conditions:

• Thick wall with hollow
  Walls with a large hollow or clamshell brickwork require two anode grids

Application of electrodes:

• Gridded anode outside above the ground
• Gridded anode inside above the foundation
• Rodded cathode outside in the ground
• Rodded cathode inside under the foundation

5th example

Conditions:

• In the absence of horizontal and vertical barriers
  Basement ceiling higher than bare ground

Application of electrodes:

• Gridded anode 1x inside partially above groundlevel and 1x inside above the foundation
• Rodded cathode outside in the ground in an equal distance to the gridded electrodes

6th example

Conditions:

• In the absence of horizontal and vertical barriers
  Basement ceiling and bare ground on the same level

Application of electrodes:

• Gridded anode 1x outside above the ground and 1x inside above the foundation
• Rodded cathode outside in the ground in an equal distance to the gridded electrodes

7th example

Conditions:

• Construction on the outside ground not possible because of e.g. sidewalk, street or pipes
  Drill through wall for rodded cathode

Application of electrodes:

• Gridded anode inside partially above the ground
• Rodded cathode outside in the ground

8th example

Conditions:

• Construction work only possible in the basement, no water entering from the side

Application of electrodes:

• Gridded anode inside under the basement ceiling
• Rodded cathode inside under the foundation

9th example

Conditions:

• With outside ground drainage system

Application of electrodes:

• Gridded anode inside above the foundation
  Alternatively outside above the ground
• Rodded cathode under the drainage system

10th example

Conditions:

• Underground vault with thick walls

Application of electrodes:

• Gridded anode 1x outside above the ground and 1x inside at the upper section of the vault
• Rodded cathode inside under the basement floor, holes drilled into the ground

11th example

Conditions:

• Cascade circuiting for tall buildings with an extremely high level of moisture, e.g. in churches, towers, historical sites

Application of electrodes:

• Gridded anode 1x inside at the upper moisture rim or higher
• 1x inside above the ground
• Rodded cathode outside or inside in the ground

12th example

Conditions:

• Visible brickwork e.g. quarrystone, sandstone, brick, fieldstone etc.

Application of electrodes:

• Gridded anode is replaced by contact band inserted in the jointings
• Rodded cathode outside or inside in the ground
