Column foundation with own hands

Several types of foundations are distinguished in construction practice, one of which is columnar. It is very popular both with professional builders and with individual business owners who are engaged in erecting wooden houses, bathhouses and other necessary buildings on their own plot.

What makes such excitement? From the fact that this foundation is obtained not only reliable, but also attractive economical, since the columnar foundation with their own hands is simple to construct, and consequently, there is a high probability of saving costs for the construction of a conceived project.

What is a columnar foundation?

First of all, it should be noted that the construction of columnar foundation with their own hands or hands of craftsmen, is appropriate where it is planned to build light structures, such as log houses and does not provide for the presence of basements.

In itself, this type of foundation is an "ennoy" number of poles located at the corners of the future house, in places where the walls intersect and under the bearing beams. In a word, in those places where the maximum load is concentrated, under the piers, corbel crowns, etc.

From a constructive point of view, such a foundation can be stone or wooden, and the manufacture of columnar foundation can be either monolithic or prefabricated. And the design of the prefabricated version, which includes elements such as:

RC blocks;
stone;
brick,

is not considered absolutely reliable due to "unsure" joints, but it is built fast enough.

But a monolithic analog made of reinforced concrete and forming a seamless sole, on the contrary, is considered a standard of strength.

Regarding the depth to which you need to lay the foundation of the foundations - there are also two options:

One of them is recessed;
The second one is shallow.

Which one to choose depends on the type of soil in your area, the level of its groundwater and freezing. For example, the first type of foundation is ideal for clay soil with abundant waters. It can be laid down to a depth of half a meter to a meter.

A shallow - used where there is rocky or sandy soil. Its maximum depth of the bookmark can reach seventy centimeters.

How to build a columnar foundation yourself?

Before embarking on the implementation of our plans, use the tips of our site and familiarize yourself with photos and video stories about how to build a columnar foundation with your own hands. They will certainly help you to understand the device of the columnar foundation more quickly, and the technology of how the marking, waterproofing and filling of the column foundation are carried out on their own.

So, if you plan to build a cabins, a bathhouse or something similar from a log house, then the most optimal and not overhead option will be a pillar-pillar foundation where concrete blocks are used. Typically, for one support, four such blocks of 200mm x 200mm x 400mm size are required. And their total number depends only on the size of the building as a whole.

The very first blocks are simply dug into the ground, and already on top of them, until the required height is reached, the following blocks are attached. Note that for wooden houses the column-pillar foundation is constructed exactly as well, but for houses made of bricks, either a foundation with a grillage or a belt foundation is erected.

Grillage - this is a special cushion-sole, which loads all the load on the ground. It can be both low and high. In this case, the low is under the ground, and the high, can be much higher than the ground.

If the grillage should be concrete, then for it it is necessary to build a wooden formwork of boards, weld the carcass reinforcement and pour concrete.

In general, from the technological point of view, the foundation pillars can be made from asbestos-cement pipes, which after being lowered into the well are poured with concrete. Then, in order for the concrete to grow, these pipes are lifted, and again the concrete is poured, not bringing to the top of a pipe of centimeters fifteen. Well, when the crowns of the building are already connected with concrete, they are simply fixed to the pipes by means of special corner joints and anchors.

This kind of foundation is really very economical, as not only materials but also labor are saved in the construction - everything can be done independently and without the intervention of working masters.

Belt-columnar foundation

Belt-columnar foundation with their own hands is constructed as follows:

1. After all pre-marking work is done, poles are arranged. For example, concrete. And in this case, to provide waterproofing can be a little cunning. Namely, twist the ruberoid in a layer so two, having formed thus the necessary diameter, and all connections properly to glue. The pipe must also be glued along the circumference and inserted into the bore hole until it stops.

Reinforcing frame is knitted and welded from a six-millimeter wire and reinforcing bar( 10-14 mm in diameter).And the top of these rods should protrude centimeters by 20-25 from the well.

2. Now you can start pouring concrete. First, a little, centimeters 25, lifting the roofing material, so that the concrete grows and forms a pillow. And then finish it.

3. A wire frame is welded and welded from a reinforcing wire or rod, which is welded to those rods that are already sticking out of the poles. The wire will be located in the transverse direction of the foundation tape, and the rods in the longitudinal, thus forming horizontal bridges.

4. Next, the formwork is mounted. For this, boards( plywood, particle board, and even iron sheets) with a thickness of 4 and a width of 15 centimeters are used.
