The durability of your fence not only depends on the quality of materials used to build it but also on the foundation supporting the structure, especially on uneven surfaces.
Key parameters that are important for selecting the correct type of foundation are:
Durability and strength
Time required to set up
Beyond these, you may also have some other hidden requirements that you may want to discuss with your installer:
If your plot is at a different height than the neighbouring one - the correct foundation can help level the area and prevent material from spilling from the nearby plot.
If the surface is uneven - a suitable foundation can stabilize the area and protect against erosion
If you plan to keep pets in your garden - the foundation can prevent the digging of trenches and escape from underneath the fence.
If you only want to mark the boundary or to ensure privacy, then a simple column foundation will be enough. It will be the most economical and the quickest option available. But if you are looking for a long term durable option, you can choose a strip foundation setup. Betafence posts can be installed with both type of foundations.

Strip type foundation:
When installing your fence with a strip foundation, you have the choice of a traditional, below-ground foundation, or a prefabricated above-ground concrete foundation.
Installation of a below-ground foundation involves deep digging and requires more equipment. It is also the more costly and time-consuming option, particularly as it requires installation in specific weather conditions to allow for the base to set which may mean waiting longer to have your fence to be installed. However, it has a better advantage in terms of stability and durability. It will effectively prevent erosion of topsoil and provide immense support to the permit. It is especially recommended when the fence will be installed on a difficult, uneven surface. This type of foundation will last longer.
Prefabricated Concrete Foundation
A prefabricated concrete foundation is usually quicker to install, but it's not as strong as foundations below ground level. Since the foundation is precast, you don't have to wait for the concrete to dry up. This can potentially reduce the labour cost as well. Since these are precast in standardized length, the cost of materials also goes down. This method requires minimal digging; only up to a third of the height of the concrete to secure it. You should arrange with your installer whether you or they will supply the foundation. The main purpose of the prefabricated concrete foundation is to block the gap between the fence and ground, offer better aesthetics, and provide additional support to the fence.
