Foundation under the bath with a sink. Sewerage in the bath: device and design features

A quality foundation is the foundation of any building erected on a personal plot. At one time, to create this design, various stones were used, smeared with clay and exposed to the structure of logs. Today, there are many construction methods that allow you to create a solid and reliable support.

What determines the choice of the basis

The foundation for a bath with a drain is chosen for each structure individually, depending on the material for assembling the bath and its general dimensions, the geodetic characteristics of the region of residence.

The following types of bases are used:

• Mixed species is rarely used for baths, it is optimal for soil with a high location of water and quicksand.
• Tape is the most popular option, suitable for soils with low groundwater occurrence.
• Pile-screw, or columnar, is applicable for buildings from rounded logs or beams on sandy ground.
• Monolithic is formed on soils of a floating type with a high water distribution.

Place for building

Selection of a site for erection requires a very serious approach, since the design should serve for many years. Perhaps the device of the bath standing separately and creating an extension to the house itself. In the latter case, the foundation must correspond to the foundation of the house and the general binding. It is not recommended to make a strip foundation, if the building itself is on screw piles.

A separate steam room should be located away from trees and shrubs, since sparks and smoke from heating are not very useful for them.

What role does the project have?

As for any other construction, before making a foundation under the bath, Preliminary planning is necessary, but it is not so important whether the building will be registered. A typical project is the fastest option, providing the possibility of extensive choice. In addition, it will require estimates in which all material and costs are calculated.

Ribbon foundation

If the territory is swampy or garden soil, the device bath Can be limited to the ribbon type of the base, which is a groove filled with a solution. After complete drying, the vapor barrier is laid, most often in the form of a ruberoid. The footprint with a width of about a meter will help in providing protection from groundwater due to clay and gravel.

Construction on piles

If the quality of the soil is unsatisfactory, the pile foundation will be the exit from the situation. The factors contributing to his choice include the fast formation speed and light construction. The emergence of difficulties is possible when filling the space between the existing posts, but here, with some effort, you can complete all the work quickly enough.

Piles are usually clogged into the soil with subsequent merging with the help of beams. Before you make a foundation for a bath, you need to take into account that the distance between the auxiliary and the main pillar should be at least two meters. Formed leading poles with the help of bricks, it is also possible to use rubble stones, asbestos-cement pipes and concrete.

In the pit after the installation of poles, sand is poured down to the middle of the pit level, after which it is wetted by water and densely packed. Between the pillars a wall is formed, while the base rises to the level of the soil, is leveled with cement mortar and covered with a roofing material.

Column base

The pillar foundation under the bath is common during construction on the ground with a high content of fine gravel, sand and clay. Its foundation is made of columns of concrete or bricks, installed with a minimum step of two meters. Before pouring the pillars are buried at a depth exceeding the level of freezing in the winter. Next, the partitions are laid out between all the posts and the roofing material is laid. It is worth noting that it is undesirable to use slit red and silica brick, because they are unfit for such a structure.

Despite the many advantages, it is quite difficult to determine the depth of the foundation for a bath of this type and the required number of piles. In addition, it is necessary to attract specialized equipment for producing wells.

What you need to know

Formerly, in the bathhouse, the unorganized drainage of water produced through holes in the floor was made. But with the development of technologies, the improvement of sewage systems has become more common, which enable the competent organization of water flow. Foundation for a bath with a drain Should take into account all the constructive nuances.

During construction, you can not do without relevant knowledge and skills. But at the same time you can independently equip the steam room and make a foundation. If the purchased area already has a bath without an organized drain method, it is possible to arrange the sewage system on its own. For this, modern materials are used that collect and divert water from the building.

You can get substantial savings if you take care of all the amenities beforehand, before the bathhouse starts. The entire process of installing the wastewater system is to fasten the plastic base, which must then be mounted on the floor. In the absence of a plastic sheet, it is possible to use a membrane that is customary for artificial reservoirs. It has many undeniable advantages:

• Environmentally friendly material;
• Ease of installation;
• Water resistance;
• Robust and thin construction;
• Application at a wide temperature range;
• Perfectly exposed to gluing and soldering.

Course of work

In addition to PVC film, you will also need to purchase a plastic ladder. The floor should have a hole slightly larger than the diameter of the ladder, since there will be a film there. Its thickness is about 1 mm. A ladder is installed in the corner of the room where the lower part of the slope is located.

A through hole in the floor, through which the sewerage in the bathhouse will pass, is cut using a jigsaw or other available tool. Formed after sawing the ends of boards should be subject to treatment with a special composition for wood, which protects from decay.

It is worth paying attention during the installation of the gangway so that it does not go beyond the floor level, otherwise it will interfere with the installation of wooden gratings. After this, you can start laying the membrane or film, they already fixed the ladder. It requires extensive lubrication with plumbing sealant at the joints with the film. In order to ensure that the sewerage in the bath has a reliable fixation, the pipe is tightly fixed to the lags or base of the floor.

Naturally, periodic replacement of the membrane is required. But despite this, this method is economical and simple, because it needs to be changed every 3-4 years. Sewage pipe, passing under the base, is insulated with special materials. It is worth considering its dimensions, since the length should be enough to pass under the foundation and drain water into the gutter. It is desirable that the construction of the bath was carried out not less than five meters from the septic tank.

Possible difficulties

The owners of the bath often with the creation of sewage problems in the pipes through the base. There are two ways:

• Direct flow under the foundation;
• The formation of holes in the base and the laying of pipes through them.

At first glance, it may seem that holes are easier to arrange when the foundation under the bath with the sink is at the initial stage of creation, but this is not always feasible. There is also the possibility of a discrepancy between the planned size and the parameters of the pipes. This is possible for the following reasons:

• Complexity in the design and creation of the foundation;
• Making changes to the project at the time of installation works;
• Shrinkage of soil or its loose structure;
• Low quality of used materials.

Despite the possible inconsistencies, many experts advise drilling holes in the finished base. But it is not so easy to drill a solid concrete structure. It also requires maximum care, because even a large crack that has arisen in the base, can lead to its uselessness.

The foundation for a bath with a sink is in any case created taking into account the further implementation of wastewater disposal. That is why it is so important to compile a detailed work plan, the product of all calculations and to determine in advance the type of sewerage.
