Despite the fact that the columnar and strip varieties are unchanged among domestic developers, the brownish foundation is characterized by many advantages. It is an almost perfect solution for plots located on the slopes, and in the territory with problem soil. On the ground where the development is carried out quite tightly, such a foundation provides an opportunity to create even a 2-story bath without any problems for the soil and nearby structures.
The essence of this variety of the foundation is that the piles are not driven into the ground with force. Due to this, there is no damage to soil layers. A small well is made in the ground, in which the tube is installed and filled with a solution.
An interesting and effective solution is a pile foundation, which is based on brownish piles with insulation materials. The most common option is polystyrene foam characterized by a rigid structure. It is fixed to waterproofing and sprinkled with earth. Do not forget that polystyrene foam is an excellent shock absorber for soil tuning forces.
It is important that the foundation on bored piles is not able to break the communications previously equipped on the site. And the fact that the basement in such a building is not equipped in the future is not able to call a serious drawback for the bathhouse. This is due to the fact that this room is simply not provided for it on the site.
The main advantages
Long period of operation (more than a hundred years).
Universality (the possibility of use, regardless of the type of soil and features of the site).
The relative simplicity of creating.
Features of formation
It is customary to pour a brownish foundation with a rapidly solid cement. It must be diluted in small portions – whenever the previous layer is pressed.
The wells are filled differently. Often, for these purposes, developers use concrete. However, a solution mixed with a stone is also suitable: limestone, pebbles, etc. It is important that the filling material is even and strong.
For effective compaction of concrete, a specialized drill is used. It is he who forms the necessary mechanical vibration. Thus, it is possible to completely prevent the possibility of minor voids in piles.
