Effects of Constructing on Expansive Types of Soil
Expansive soils are soils that contain minerals and can absorb water making them increase in volume. They expand to ten times more and the more water they are exposed to the more they absorb and the greater their volume. An example of such soil is expansive clay soil. Buildings and structures tend to get damaged due to the expansion of soil that exerts force leading to cracking and even worse effects. When the soil on the constructed structure swells it may damage foundations, floors, and basement walls. It may also damage the upper parts of the structure in case the movement is notable.
Another destructive property of expansive clay Texas soils is that they undergo shrinkage on drying out. When they shrink or swell, they eliminate the support from structures leading to damages and soil fissures. Fissures enhance deep penetration of water in the case of rain or runoff water. The impact of the swelling and shrinking becomes worse after some time due to the recurring stress on buildings. This trait in soils has led to huge losses to property owners and the effects have become more deteriorating than those from floods, hurricanes, earthquakes, and tornadoes. The damages caused by expansive soils is rarely noticed since it builds up with time. Some people have been led to believe that this kind of damage happens to all structures as they age. It is however key to note that this is a poor construction practice that can be eliminated during the construction work.
