Foundation for a bath out of the blocks

Banja refers to light constructions, and in order to save instead of massive monolithic tape can build a foundation for a bath out of the blocks.Advantages of block foundation are obvious: its construction does not require heavy machinery, fixtures attachment, kneading cubic meters of concrete.This foundation can easily survive the bath load, quickly erected and does not require large expenditures.

Foundation for a bath of blocks can be either a tape, and columnar, its design depends on several factors:

• dimensions and structure of the material;
• design of the basement and floors.

Banja wood refers to light buildings, so it is sufficient pier foundation of concrete blocks.The floors in the bath such as a rule, carried out on the wooden joists.

If bathhouse built of brick, foam concrete, or it has a significant size should be selected weakly deepened strip foundation from concrete blocks.It is also easier to strip foundation if necessary solid color on the sandy floor preparation.

pier foundation for a bath of

Full-bodied blocks for the foundation of concrete blocks have dimensions 390h190h180 mm and a weight of about 30 kg.For melkozaglublennogo columnar foundation blocks of only three or four rows of masonry, that is, on one support post must be from 6 to 12 units.

1. territory for the construction of baths free of debris and foreign objects, remove the top layer of fertile soil to prevent degradation processes under the building.To stop the growth of the grass area can be covered with geotextile and fill with gravel or sand.
2. Produce markup using pegs and strings, performing external and internal contours of the foundation.Crossing the twine forming the angles, which when laying dub poles.Check the level of horizontal strings.Mark up the place of installation supporting pillars: a bath in the corners at the intersection of walls, and the walls at a distance of 1.5-2 meters.In order to support the floor slabs impose additional supporting pillars in the center of the structure.

3. The pillar sites dig pits depth of 30-50 cm and a width of a little more than the size of the pillars.On the heaving soils erect necessarily a bed of sand or gravel thickness of not less than 30 cm, to the bottom of the ram thoroughly and covered with gravel or sand.Bedding is compacted, spilling water and then placed on a layer of roll her waterproofing - roofing.
4. Getting masonry supporting pillars.The bars are placed with ligation of rows in a row - on two or three bloka.Kladku to produce mortar: 1 part cement brand M400 3-4 parts of sifted sand.seam thickness -. 1 cm in the process of laying and use levels are guided by pre-stretched twine.

5. After drying solution pier foundation must be waterproofed from the effects of ground moisture.The easiest to use for this purpose surface waterproofing mastic asphalt.Before applying the mastic primer treated surface of the blocks, dried, and then applied to all surfaces of two or three layers of mastic or brush roller.The horizontal top surface of the pillars further waterproofing roofing material, pasting it into the top layer of asphalt mastic.Backfill the excavated pits produce the usual sand or soil.After filling can proceed to further construction.

Strip foundation for a bath of

blocks for bath foam concrete, brick, or a two-story bath with a loft safer to use strip footing - he was able to take heavy loads, is not much more expensive in price.Also strip foundations operate in the case of sand casting floor preparation.Such floors often perform heating, for example, in the washing compartment, or in the recreation room.The height of the foundation in this case should take into account the height of the floor box.

1. The pad aligned, mark, remove the fertile layer and dig a shallow trench under the strip footing slightly wider base, make it easier to carry out after the masonry waterproofing.

2. bottom of the trench necessarily covered with sand or gravel - it improves waterproofing baths and facilitates removal of moisture.On wet soils perform drainage.Filling must be at least 20 cm, and align it carefully trambuyut.Pri performing screed need to lay a foundation for communication - pipes for water supply, sewerage, power electric cable input.

3. concrete blocks at the bottom of the trench lay strips two layers of roofing material.Laying begin from corners, focusing on the layout.Laying lead to ligation, in one block wide.Cement mortar for masonry cement brand operate M400 by mixing 1 part of cement with sand and three parts water to medium density: the solution should not run with a trowel, but have sufficient ductility.
4. enough for a bath three or four rows of masonry, between the first and the second row is recommended to lay reinforcing mesh, pre-cut to size.Reinforcement of the foundation prevents deformation under frost heaving, and as the ground under the bath when winter use can repeatedly thawing and freezing, this measure will not operate in the bath lishney.Esli basement space for ventilation stack produhi.

5. basement waterproofing produce as well as in the implementation of the columnar foundations.If desired, you can perform thermal insulation of the foundation slabs of extruded polystyrene or polyurethane foam, as well as uteplennuyuotmostku.

Foundation for a bath out of the blocks - a cost-effective and efficient solution for the majority of soils, however, if the bath is set on the moors or prone to flooding of unstable soils can build a floating slab foundation with sand or crushed stone preparation.
