A common variant of construction - strip foundations under the bath

device strip foundation under the bath is the most common form of construction of the foundation, as is best suited to their technical parameters, moreover, it is easy to make your own hands.

Tape base suitable for baths from the logs and bath concrete block.

Despite the simple technology, such a foundation unit has certain nuances, which include site preparation and design.

It is with these steps and start working.

Site preparation and design

device strip foundation begins with the selection of a suitable site, with the following characteristics:

• nesypuchy ground;
• deep-seated groundwater;
• dry ground;
• shallow soil freezing in the winter.

Site preparation for the construction of the base under the bath starts with the cleaning of all superfluous.After that remove the top layer of soil and leveled ground.

sure to do a background check horizontal platform.This can be done with the building level or better gidrourovnya, which is more accurate.

Now you can do the layout, which uses a theodolite or rope and pegs.Marking begins with the inner contour of the foundation.

First you need to mark one side of the structure of the future, setting the two pegs between which is stretched a rope.

Then you need to determine the right angles and perpendicular to the length of the tape measure to postpone the parties and set the pegs.

now checked diagonal formed a rectangle, which should be the same.And if they really are the same, between the pegs you need to pull the rope.

Otherwise, you need to check the correctness of markup.In the video you can see how to make a layout for the bath from logs or blocks.

Thus is marked the inner loop, and then parallel to it - outside.base width should be 10 cm greater than the width of the walls of the bath.Now you need to partition the internal partitions.

should be borne in mind that if provided the foundation for the furnace, it is done simultaneously with the foundation for a bath, and from a log and laid out of the blocks.

After marking can proceed to the excavation.

Earthwork

first step is digging the trench, the depth of which depends on the level of soil freezing.The depth of the trench must exceed the level of freezing at 20-25 cm.

also base depth depends on the weight of the bath.The optimum depth of the basement -. 30-100 cm Width hole should be wider foundation 25 cm for installing formwork.

If bath is small, you can dig a trench with their hands, but to speed up the process, you can resort to the help of technology.

At the end of digging to the bottom of the hole should be put a pillow, which is a layer of sand and gravel thickness of not less than 10 cm and not more than 25 cm.

To cushion was denser layer of sand need to add water and wait untildry, only then to fall asleep gravel, tamping and lining quality.

On the pillow can not save.It is better to 20 cm pillow 1 m concrete than 5 cm cushion of 1.15 m of concrete.

Installation work

finished excavation work, you can begin installation of foundations.You should know that the tape base may be monolithic or blocks.

first consider the device monolithic foundation with his own hands, for which, in the first place, set formwork.Formwork can be made with your own hands, it will require edged board.

In order to make it easier to remove the formwork and make out the nail heads should be located outside.

To enhance immobility of formwork needed to bond the opposite sides of wooden slats.Then

construction using staples or nails to the inner side of the formwork is recommended to attach the polyethylene, roofing felt or roofing material to prevent wetting of boards and getting the solution in the gap between the boards.

next step is reinforcing formwork foundation that will add strength and durability.Sections of reinforcing bars are installed on the bottom of the hole in two rows at a distance of 5 cm from the formwork.

height of the reinforcement should be 5-6 cm below the foundation.After that you need to put on the bottom of the horizontal rods that attached to the vertical support with a wire.

to long life is necessary to use valves with a diameter of at least 12 mm.Segments connect better reinforcement wire.

can start pouring concrete mix After installing the valve.To the mixture it is recommended to use cement M-500.If the filling

performed at low temperature, the need to add a plasticizer solution.The solution can be prepared in two ways.

first method is used for cement and sand in the ratio 2: 1.

Such a mixture has a high strength, but quickly hardens, it is inconvenient if the work is done by one person.

For the second method require cement, sand and gravel in a ratio of 1: 3: 5.The solution solidifies slowly but is less reliable.

adding sand and gravel mixture, the foundation can be strengthened.

All the components to be mixed in the dry state, and then add water and mix.The solution should be prepared correctly, or may soon occur cracking foundation.

finished mixture is poured into the formwork.If you can not pour the mixture at a time, the solution should be filled in layers of not less than 25 cm.

potting mix made from a height of 50 cm, or after drying concrete can delaminate.When you have finished pouring, the concrete should be leveled and pierce in several places for the air outlet.

Shoot formwork recommended seven days, but sometimes it is done in three days.In hot weather, the concrete should be moistened with water four times a day, and if wet - covered with polyethylene.

erect a wall of logs, timber, or blocks can be only three weeks after complete solidification of the solution.Before the construction of the foundation is covered with waterproofing.

strip foundation blocks of the apparatus with their hands is more simple, since no reinforcement is required, kneading the solution in large quantities.

addition, block foundation is being built quickly, it is durable and has a low cost.

For such a foundation is laid on the bottom of the trench 2 layers of roofing material for waterproofing of the foundation.

Stacking blocks made with ligation, in one block wide.Need for masonry mortar, which is necessary for a part of M-400 cement mixed with sand and three parts water added.

Video:

mixture needs to be done medium thickness.

Stacking blocks is carried out in a number of 3-4, and between the first and the second row is recommended to lay reinforcing mesh, which will make the foundation more solid.

finished laying the blocks, you can immediately proceed to the construction of the wall from logs or blocks.

Strip foundation for a bath is easy to do with your hands, but you need to properly perform all the steps of work to design a robust and durable.
