Soil quality is the most important factor to look out for when procuring a land. Inspection of soil quality in proposed land is important to ascertain the soil stability which determines the durability of the structure to be built on it. Soil inspection is needed in either private or commercial building construction. Soil types have their various effects on the foundation of a structure it holds. Foundation is the most important part of a structure. It is the lower portion of building structure that transfers its gravity loads to the earth. However, if foundation is what supports the building structure, what supports the foundation itself? Soil is the major support for the foundation of a building structure. Hence, the type of soil and it quality features to support the foundation of structure should be a great concern.
The knowledge of the soil quality and composition of a proposed land will give ideas on the stability of the foundation, hence, the durability of the structure to be built on it. Each of soil types has its properties and its supportive strength to the foundation of structures. Below are the types of soil and their effect on the foundation:
Rocky: There are varieties of rock. Amongst these varieties, bedrock, limestone, and sandstone have aberrantly high bearing capacities. Bearing capacity is the capacity of soil to support loads applied on the ground. Rock has a high bearing capacity hence its suitability for foundation. However, the drawback of rock is its implication on construction cost. A rocky land mass implies a good but costly foundation.
Loamy soil: Loamy soil is the perfect surface for foundation. Naturally, loam is an amalgam of sand, silt, and clay. and is crumbly/soft to the touch. Loamy soil handles and maintains moisture in an even and balanced way. This reason makes it ideal for foundation.
Clay soil: Clay is not a good soil to build a foundation ; it is a poor soil for support. Clay soil has high expansivity which makes it unsuitable for foundation. It expands greatly when wet and shrinks remarkably when dry because of the fine particles it contains. It is easily moved, manipulated, and shifted after absorption of water. Pressure is induced on the foundation due to the changes that occur from the variation in moisture content. This pressure can cause a vertical movement on the foundation, hence, an eventual crack.
Peaty soil: Peat is another poor support soil. Like clay, its expansion and shrinkage is dictated by weather condition. It has a high porosity and mostly found in wetlands dark brown/black soil formed by decomposed organic material. Peat has a low bearing capacity, hence, unsuitable for use in foundation of a building.
Sandy soil: Sandy soil has the largest particles and drains easily because of large openings. It binds together when compacted and moist, making it suitable for foundation support. Nevertheless, at long run, gaps can be created below the foundation from loss of friction in the sand particles – a disadvantage of sandy soil being used.
Project planning requires an elaborate duty of detailed observation. The types of soil is important in forecasting the stability of the foundation and hence, the durability of the structure. Distance is no more excusable in project management. In absentia, your project is still bound to come out perfect with a project monitoring agent. Project monitoring commences at the project initiation stage.
