Rubble soling is a method of providing a stable base for construction by using a layer of large, rough stones or rubble. It is commonly used in construction projects where the soil is unstable or weak, and where there is a need to create a solid foundation for the structure.

Rubble soling is typically used in the construction of roads, bridges, dams, and other large structures. The technique involves laying a layer of large stones or rubble on top of the soil or bedrock. This layer acts as a foundation for the construction above it, providing stability and support for the structure.

The stones or rubble used in rubble soling are typically chosen for their size and strength. They are usually irregularly shaped and rough, which helps to create an interlocking pattern that provides stability and prevents the stones from shifting or sliding.

The stones are laid in a uniform layer, with each stone placed in close proximity to the adjacent stones. The gaps between the stones are filled with smaller pieces of rubble or gravel to provide a level surface.

The depth of the rubble soling layer is determined by the weight of the structure that will be built on top of it, as well as the strength and stability of the soil or bedrock below. In some cases, multiple layers of rubble soling may be used to provide additional stability and support.

Rubble soling is typically used in areas where the soil is weak or unstable, such as areas with high water tables or areas with loose, sandy soil. It can also be used in areas where the bedrock is uneven or irregular, as the stones can be used to create a level surface.

One of the advantages of rubble soling is that it is a relatively inexpensive and simple method of providing a stable base for construction. It does not require heavy machinery or specialised equipment, and can be carried out using simple hand tools.

However, there are also some disadvantages to rubble soling. The technique is not suitable for all types of soil or bedrock, and may not provide adequate stability in areas with very soft or unstable soil. In addition, the stones used in rubble soling can be difficult to source, especially in areas where there are no natural sources of large, rough stones.
