In this article we will talk about how to make a foundation for do-it-yourself baths, consider options for tape and column foundation.

Before building the foundation, you need to decide on the type foundation, based on the type of soil on the site. If before it was built a house, then the type of soil is already known.

  • Wet or bulk soil requires a strip foundation.
  • Clay soil – columnar.
  • Soil with a vertical drop – screw.
  • On swampy soils, the foundation must be chosen monolithic.

The most optimal options are tape and columnar foundations. The choice of them can be made at the adoption stage. decisions from what building material will be erected the bathhouse.

For instance:

  • if you plan to build a bath of blocks or bricks, strip foundation required.
  • if the building material for the bath becomes a wooden beam or logs, a columnar foundation will do.

Construction tape

To organize a strip foundation, you will need:

  • tape measure, cord, wooden stakes;
  • shovel, reinforcement in the form of metal rods and light wire for binding it;
  • sand, cement and gravel for concrete solution.

First you need to mark the corners with stakes using a tape measure perimeter of the future bath. A taut rope will help you get a level foundation.

Trench under the strip foundationTrench under the tape foundation

On the perimeter of the future bath you need to dig a trench depth below freezing level in the area. Trench width should be at least 30 cm. Its outer edge should pass along markings made with stakes and rope.

At the bottom of the trench, pour 20 cm of sand and gravel, spill it and tamp it well.

Fittings are laid on top – ready-made metal gratings with a rod thickness of at least 1 cm. If reinforcement represents separate metal rods, they can interconnected using a soft wire.

After installing or laying reinforcement on the prepared bottom trenches can begin filling it with concrete mortar. Preferably position the reinforcement so that it does not touch the edges of the trench and in the same time did not rise above the surface of the soil.

For a bath, it is advisable to use high grade cement and fine sand – this will provide additional strength future construction.

If the strip foundation should rise above the surface soil, before pouring concrete mix it is necessary to establish formwork from wooden boards. After a few days the formwork can be removed and the foundation left to dry on another a week or two.

Columnar construction

Scheme of columnar foundationBar chart foundation

If a column foundation is required, the following will be required. building materials and tools:

  • stakes, tape measure and twine;
  • manual or electric drill;
  • piles – wooden posts, asbestos-cement or metal pipes or bricks;
  • cement, sand and gravel.

First, the territory is marked: pegs are located in the corners the perimeter of the future structure, a rope is stretched between them.

Types of pillarsTypes of Posts

Marked places under the pillars: each hole should be located from the previous one at a distance of 1-1.5 m. Observe this distance is necessary for both external and internal bearing walls.

When using wooden logs, they first need to treated with an antiseptic to prevent premature rotting building material.

If the foundation foundation are pipes with a diameter of 20 cm – metal or asbestos-cement – they must be poured concrete mortar during the arrangement of the base under the bath.

First, using a manual or electric drill in marked ground holes are organized in the depth of 1.2 to 1.5 m and 25-30 cm wide.

At the bottom of each hole is placed a 20-30 cm layer sand and gravel cushion, it is spilled and thoroughly tamped.

A prepared wooden pole is placed on the prepared bottom or a pipe of the required height.

Reinforcement is placed in the middle of the pipe or around the column, after why the pipe is filled with concrete, and around it, as well as around the column, compacted soil.

Under a bath from a bar

Under a bath from a bar

If the bathhouse is from a bar, then for such a construction you can choose types of foundation:

  • tape;
  • columnar;
  • monolithic.

Consider the features of their construction directly for the bath from timber.

Tape

Ribbon

Concrete is poured along the intended perimeter. It has the following positive characteristics:

  • This type of foundation is able to withstand two floors, since it the construction is strong enough.
  • It is very beneficial for the construction of the bath, as it has a low thermal conductivity level.
  • There is an opportunity to build an underground room or cellar.

Columnar

Columnar

If the bath will be small in size and moderate in weight construction, then you can make a columnar foundation. Mainly This type of foundation is used for these types of soils:

  • clay;
  • gravel;
  • sand.

You can highlight some of its advantages:

  • A relatively low price for construction.
  • If the ground in your area is sloping, then the columnar foundation will allow the construction of the bath.
  • Very easy to manufacture, so you can completely do without help of specialists.

Monolithic

Monolithic

This type of foundation is relevant for any type of soil. His the design is a reinforced concrete monolith. Among his advantages can be identified:

  • High strength and reliability.
  • It is possible to build several floors.

The main drawback of the monolithic foundation is high cost price.

Under the frame bath

Under the frame bath

Under the frame bath is meant the use of ready-made frames for quick construction. Given these and others features of such a building, we compare the advantages of manufacturing strip and column foundation.

Features of the strip foundation

Features of the strip foundation

It is important to understand that the design of the frame bath implies arrangement of sufficiently thick foundation walls to hold the entire the buildings. Depending on the material used, thickness foundation may be different:

  • Reinforced concrete – thicknesses from 10 cm.
  • Natural stone – from 5 cm.
  • Concrete – from 25 cm.
  • Limestone concrete – from 30 cm.

When building a foundation, it is imperative to implement its deepening to a level below freezing to 20 cm. on the other hand, it makes no sense to equip the foundation with a depth greater than 70 see From here it becomes clear that the strip foundation It is divided into two categories:

  1. Shallowly buried.
  2. In-depth.

For the construction of a frame bath, it is enough to use finely deep foundation up to 60 cm deep.

Features of the column foundation

Features columnarColumn features

Although a strip foundation has many advantages, it is used in most cases for buildings made of blocks or a brick. Therefore, if the bath is wooden, then you can stop and on a columnar foundation. During its construction, you will need much less financial costs for the source material.

Such a foundation is especially relevant for the construction of chopped, block and frame constructions. Since between pillars there is no need to build special jumpers.

However, if the soil is slightly bearing, then this type of foundation is not relevant. If you want to equip the basement, then with this the foundation to do this will be problematic.

Foundation for the furnace

Basis for a bath stoveBase for a sauna stove

If it is planned to install a brick oven in the bathhouse, for it you need to organize your own foundation.

A hole is being prepared at the location of the future location of the stove in soil with a depth of 50 cm. If one of the pillars of the foundation, then it is not installed to the full height, but on at a depth of 50 cm from the surface, it becomes square or rectangular mini monolithic base.

The bottom is covered with a sand and gravel cushion, tamped, and fittings are placed on top. At the end, the hole is poured with concrete solution.
