Jimi Hendrix sang about castles made of sand falling into the sea eventually, but soil erosion does not only affect castles made out of sand. Soil erosion can occur anywhere, and for any number of reasons but the most common is water, which is ever flowing, continuing its way to the sea.
Three of the best ways to prevent erosion are to use land according to its capabilities, protect the surface soil with a cover of some sort, and manage water run-off to prevent it from eroding away at the soil. By doing the appropriate soil testing you will be able to determine a lot about the soil and surrounding conditions, giving you are clearer picture of how to prevent further erosion. It can also give you an indication about what is required with building, relocating or raising a house.
Capability of Land
The position of land, its slope and soil type are important factors, which determine what the land can be used for. Different soil types are best for different types of land use, as the various types of soils have different strengths. Land that is good for crops and grazing may not be the best choice for building a house. A house that has been built on soil that is not strong enough, could cause the house to crack, sag or even fall down.
Run-off and Surface Cover
A major cause of erosion is through the natural elements of wind and water. Surface cover is important to prevent rain from eroding bare soils and wind eroding the soil particles, which can cause erosion problems. Water run-off, if not appropriately deviated, can cause extreme erosion in some cases, which can massively deteriorate a land mass over time. Before building a house, the area needs to be thoroughly assessed by a soil expert to determine these factors of wind and water, and how to prevent them from causing soil erosion around the foundations.
Black and White Houseraising and Restumping assess all aspects of the land when planning and working on raising or restumping a house. Knowing the quality of the soil will determine what preparations are required for carrying out the work, as well as which materials will be the best to use for the foundation of the building. Proper assessment of the soil and land capability, leads to a ‘best case scenario’ with house raising and restumping, preventing erosion of the soil around the foundations of the house, and minimising the impact of the elements.
