Soft rocks are very important geomaterials since they are heavily used in construction for example, buildings, road and dams but they sometimes seem to cause some problems due to their sedimentary properties like fast weathering and low strength. Weathering is a process in which rock break down or dissolve with the help of natural agents. Weathering and erosion are constantly changing the earth’s surface, so that has a big impact on construction and usage of soft rocks over time. Weathering can be either mechanical or chemical. Some regions in the world mainly possess weak sedimentary rocks and very low in other stronger rock like igneous or metamorphic. Because of the these weak characteristics, it might be tough to use soft rocks especially since some methods and systems are made mainly for hard rocks. These issues that we are dealing with lead to the need of the understanding of soft rocks, how they work and how to prevent them from breaking up and crumbling in order to maximize their usage.

Weathering and Erosion

Weathering is the process where rocks and minerals break down or dissolve into smaller pieces and fragments. Erosion is then the transportation of weathering remains. This is done with the help of natural agents such as water, wind, animals..etc. It all depends on the composition of the rock, different agents such as temperature change and rainfall amount. Water for examples is the most common, like when it seeps in the pores of rocks, freezes overnight and…
