How to build a foundation of pipes

Any construction begins with the construction of the foundation, the construction of which can be of various kinds. If you plan to build a small and light building, then the easiest way to perform the column base. In this article we will take a closer look at how to make a foundation of pipes with your own hands so that it is strong enough and durable.

Features of the column base

The foundation of the columnar foundation is the supports dug into the ground, which are interconnected by a grillage.

They must be located:

• In the corners of the building;
• Along load-bearing walls in increments of 1.5 - 3 meters;
• At the intersection of partitions and walls.

Rostverk allows you to link the individual supports in a single supporting structure, the load on which is distributed evenly.

Merits

Among the main advantages of the columnar base are the following points:

Tip! To make the building on the column foundation look more attractive, the base can be hidden behind the basement panels imitating brickwork or other materials.

disadvantages

Among the shortcomings of this design can be identified the inability to perform the cellar under the house. In addition, such a foundation will not be reliable on mobile soils.

As already mentioned above, the columnar foundation is allowed to be used only for light structures, this limited use can also be attributed to design flaws.

Features of the use of pipes

You can make the column base of the building from a variety of building materials, for example:

• Bricks;
• Concrete blocks;
• Wood, etc.

However, the simplest option is to use pipes for this purpose. Of course, pipes alone are not enough to withstand the entire load of the structure. Therefore, they, in fact, perform the function of formwork for concrete.

Pipes for these purposes can be used different:

• Metallic;
• Asbestos concrete;
• Polyvinyl chloride.

It must be said that, depending on their type, the technology of building a foundation with your own hands may differ slightly. Therefore, below we consider this process separately for each type of support.

Training

The construction of the column base, in fact, like any other, begins with the preparatory work.

They are performed as follows:

• Work begins with marking the site according to the project.
• Next, with the help of a drill, it is necessary to perform the required number of wells, which should be located at a distance of 1.5-2 meters from each other. The depth of the wells should be 25-35 centimeters below the level of soil freezing, on average - 1.4-1.7 meters. As for the diameter of the wells, it depends on the diameter of the supports, most often this parameter is 15-20 cm.
• The bottom of the wells 10-15 cm covered with a layer of rubble or sand.

Asbestos pipes

The most common option is asbestos-cement pipes for the foundation, which is associated with their resistance to corrosion, unlike metal counterparts, and resistance to frost, unlike plastic.

So, the foundation of asbestos-cement pipes with their own hands is performed in this order:

• In the well is placed asbestos-cement pipe with a diameter of 200 mm, protruding above the soil level by 30-40 centimeters.
• Then two metal rods are driven at a distance of 6-7 cm from each other. The rods should be located below the support by 20 cm and so as to rise above it. The protruding part of the rods will serve as the basis for fastening the grillage.
• Next, the support is poured inside and outside with concrete of a grade not lower than M200.

Note! Before using metal tube rods, they must be treated with an anti-corrosion compound. This will increase the durability of the structure.

After this, installation of the remaining supports is also performed. The most important thing in this process is to ensure the location of the pillars on the same horizontal level. If necessary, they can be filed. (See also the article Pipe products: features.)

Most often, the grillage for such a foundation is made of timber, which is laid on top of a pole.

Plastic

Column foundation of plastic pipes is performed as described above. Therefore, we omit the technical part of its installation and consider the features of this material.

So, the advantage of plastic pipes is their cheapness. In addition, it should be noted that they are much lighter and more resistant to various chemicals than asbestos concrete counterparts. However, as mentioned above, plastic becomes brittle in the cold.

Metallic

The foundation of metal pipes is the most durable and fast in terms of construction, but at the same time, the most costly option. In addition, it requires reliable protection of metal elements from corrosion, otherwise the design will not last more than twenty years.

Such a foundation is being built on the pipes with their own hands as follows:

• Pipes treated with an anticorrosive agent become clogged below the level of wells by 50-100 cm. The most difficult part is to ensure one level for all supports.
• Next, the foundations and pits are filled with concrete. The use of reinforcement in this case is not required, since the pillars themselves are strong enough.

Tip! When erecting such a foundation, it is not necessary to use supports of large diameter (150-200 mm). Several smaller pipes can be driven into the well at a distance of 5 cm.

For such a foundation, a grillage of metal profile is preferred. Of course, it will turn out to be quite expensive, but then - the most durable. After the grillage is ready, you can proceed to the further construction of the building.

Conclusion

To perform the column base by the methods described above is really not difficult. Most importantly, decide what the foundation of the pipes will be - PVC or asbestos concrete, and then exactly follow the technology of its construction. The result will be a reliable design that can last up to 70-80 years without repair. From the video in this article, you can get more information on this topic.
