At construction of residential building it is desirable to make hydrogeological researches with the purpose to define how deeply on the parcel underground waters are located. Their proximity needs to be considered also at construction of the base, and further when in the territory of the site the vegetation lands.
Instruction
1. Construction of individual residential building – process rather costly therefore it is necessary to build housing so that it has stayed as long as possible, and operation it was not too expensive. Still before you will begin to build the base, it is necessary to define how underground waters deeply lie to consider it at construction and to secure the house against continuous flooding. Before design of the base it is necessary to conduct hydrogeological researches with the purpose to define composition of soil, level and volume of underground waters.
2. It is necessary correctly to choose waterproofing type, otherwise the proximity soil baud will become the reason of flooding of the base, mold growth on walls of the basement and wall saltpetres on walls of rooms of the first floor. Such deposits of sodium or potassium salts which are sign that moisture gets into design are capable not only to spoil finishing of walls, but also to destroy plaster coat on them.
3. Besides, also the composition of ground waters can constitute danger. High content of alkali and also sulfates can become the reason of corrosion and destruction of concrete on which surface at first the plaster raid appears, and then spalling begins. To prevent it, it is necessary not only to choose the correct type of waterproofing, but also to use such grades of cement in which there are no substances entering chemical reaction with aggressive components of underground waters.
4. The proximity of underground waters is harmful also to the majority of vegetable and garden plants which roots do not maintain constant flooding. It can become the reason that all planted by you on the site bushes and trees will badly fructify and grow, will not be able to postpone wintering and will begin to perish. The soil rehumidified because of proximity of underground waters is poor in oxygen, in it the nedookislenny chemical compounds pernicious for roots of any vegetation are formed.
5. Besides, zakisny connections, forming congestions, destroy structure of the soil, poisoning her the environment. The parcel at which surface underground waters are located too close is unsuitable for gardening and truck farming. The only thing that will grow on it well - it is grassy plants with undeveloped root system as thickness of fertile soil layer is too small.
