Geological survey section for selecting the type of foundation

A solid foundation - a guarantee of the durability of a frame house. However difficult build a solid foundation without a serious study of the soil on which it is located. In order to eliminate any unexpected difficulty after the construction of the foundation, you should order a geological survey of the site.

What is meant by a geological survey?

- The study of the relief, as well as its components, the analysis of rocks and determination of their origin.
- Spot drilling, excavation for subsequent analysis in the laboratory.
- Evaluation of geological conditions.
- Study of the disposition of groundwater, the possibility of flooding areas, the definition of slope stability.

What data will be obtained as a result of research?

The composition of the soil. As a result of objective laboratory tests you get an objective picture of the physical and chemical characteristics of soil layers. The main result of these data, - information about the capabilities of the carrier portion. This information will not only design the right frame house, but also a major fence, auxiliary buildings and internal droshky. Invalid data will entail the deformation of buildings and structures.

The occurrence of groundwater. These data determine the choice of foundation, the possibility of building underground structures: the basement, garage. The presence of groundwater occurring close to the surface requires the installation of additional drainage systems. This also determines the method of laying of underground communications.

The complexity of the relief portion. These data will help to prevent problems in the construction of a frame house, will give the answer to the question of the need to change the landscape for relief.

Water chemistry. Analysis of groundwater will answer whether you can use this water for food and watering. Additional analysis will answer how aggressively behave ground water in relation to the different materials: concrete, aluminum and so on.

Complete documentation, which provides a firm that conducted the study, including information about the methods used during the surveys of the area covered by the site, the results of physical and chemical analysis of the soil layers and the chemical analysis of soil water. long-term forecast of geological changes must be made. If there tend to do strength analysis of slopes. It provides an accurate prediction of flooding the study area. The customer receives a map of the territory on which a detailed layout.

Geological studies are transferred to the designer and architect. There is another way. Once the designer was commissioned to design a frame house, he is developing terms of reference for geological surveys.

The cost of the geological survey.

geological survey of the territory of the cost depends on several factors: the season of work, the complexity of the terrain, the complexity of the work. Before you decide on a company not worth chasing cheapness. Initially gather feedback about the company, see if she has a license to perform geological surveys.
