- Pier Foundation provides Termite control because the house is constructed above a sufficient height from the ground.
- The cost of Pier and Beam Foundation repair is comparatively low as compared to other types of foundation.
- Pier and beam foundation can be constructed on any type of land.
Disadvantages of Beam and Pier Foundation:
There are also some disadvantages of the construction of pier and beam foundation which are as follows
- If the foundation of the structure is not properly ventilated there may be chances of development of dampness.

- The construction of Pier and Beam foundation has various advantages and different types of foundations are generally constructed in areas with dry soil.
- The post and pier foundation spacing is generally kept 8 to 10 feet distance for the foundation piers in order to support the structures.
How to Build a Post and Pier Foundation?
- The pier and beam foundation can be constructed on land which is not levelled. To construct other types of foundation it is necessary to construct level ground for the construction of the building.

- Concrete slab Foundation is economical as compared to the pier and beam foundation.
- Pier and beam Foundation provides extra insulation from the air which will help you to save the energy cost and keep the place cool.
House Leveling Pier and Beam:
- Levelling is one of the most important processes which should be done before starting the construction of this structure.
- Levelling of the house is the process in which the ground or the site on which the structure is to be constructed is labeled horizontally before starting the construction of the structure.
