The foundation is the most important part of any building. Everything rests on it and without a well-performed installation, all further work can be derailed. This part of the building is especially important when you plan to build large buildings, such as cottages. They already take a lot of costs and it is better to play it safe than spend even more on permanent repairs.
The choice will depend on many factors, from the soil to the weather conditions at the construction site. Before starting construction, the characteristics of the soil, its depth and height differences are clearly calculated. They take into account the maximum permissible weight and a bunch of little things, without which everything can be destroyed by one breath of wind.
