Features, technology and stages of the construction of a strip foundation
This foundation consists of concrete reinforced tape, which connects all the supporting walls of the structure of the frame house. A significant drawback of the strip foundation is the cost of work. But at the same time, is reliable and has the ability to lay it only on little heaving bases.
Sometimes, when erecting, namely, frame houses, it is impossible to avoid laying a strip foundation, in this situation it may be necessary to carry out engineering additional work. This is accompanied by cash costs.
The strip foundation, as a rule, is laid 15-20 cm deeper than the freezing border itself, but from the ground level no deeper than 70 cm. The thickness of such a foundation can be different. Monolithic concrete, brick, laughter stone, foundation factory blocks and other different materials were used to device a strip foundation. The trapezium is the most optimal shape that is suitable for the cross -section of the strip foundation. This form transfers optimally the load on the ground. Ribbon foundations are divided into two types, such as monolithic and prefabricated.
For monolithic foundations, a pit breaks out, then a pillow of sand is sipped, which is spilled with water and after which it is compacted.
Ribbon foundations, which are already assembled, are immediately laid out from prepared massive blocks, which are usually factory performance.
Having ideas about the features of the architecture of the house, and knowing the results of geological surveys, you will learn from the designer whether such a foundation is suitable or not. And, if it suits, then which.
