A reliable and durable ribbon foundation on piles

The foundation is the foundation of any structure, accordingly, it must be reliable and durable, which is why the strip foundation on piles is very popular.

reliability of a base due to the fact that the walls of buildings are based on monolithic melkozaglublenny strip foundation and piles are located below the level of soil freezing, provides strong adhesion to solid soil layers.

Often even the old foundation is replaced with a pile foundation type.

However, the replacement of the foundation will strengthen the structure only in the case of properly executed work.

device technology advantages and disadvantages The advantages

pile-belt base include:

• the possibility of building on the low marshy ground and on land with a slope;
• low cost;
• use of a small amount of building materials;
• possibility of doing all the work yourself;
• rapid erection of the foundation without the use of special equipment;
• excellent resistance to soil movement.

Despite the weighty dignity, pile-strip foundation still has shortcomings, which include: the inability to use the piles of heavy large buildings, the inability of the basement and ground floor unit, required complex calculation base.

A correct calculation is the guarantee of a long service life of the entire structure.

But despite the existing disadvantages, this type of foundation is widespread in the modern construction world and is excellent for the construction of bathhouses, arbours, low-rise buildings and small cottages.

Types pile-tape base

pile-strip foundation is divided into certain types, different types of piles installed, which can be screw or drilled.

Screw piles look like very large screws that screw into the ground. Screw piles are made from a steel pipe with blades of screw thread.

It is the thread that provides an increase in the footprint and rigidity of the attachment in the soil. Screw such piles with your own hands or resort to the help of special equipment.

The dimensions of the piles can be as follows: diameter - 50-130 mm, length - 1600-3500 mm.

An important element in the installation of screw piles is the mandatory painting of the elements, which will ensure a long life of the piles.

As a virtue of screw piles, it can be noted that their replacement, if necessary, is made easier than other types of piles.

But still, replacement is a very complicated process, and not all jobs can be done by one's own hands.
To drill bored piles, you need to drill pits.

The technology of installing such piles depends on the type of soil. If the soil is solid and does not crumble, then the concrete can be poured directly into the drilled hole.

And if the foundation is erected in an unstable or wet ground, then you need to make a casing.

Casing is required for casing: cardboard, steel or asbestos-cement, which additionally serves as a waterproofing. The pipe must be inserted into the drilled pit and filled with cement mortar.

Bored piles are better suited for building a foundation with your own hands.

The pile-and-tape base can be shallow or not recessed at all.

A shallow foundation is used for buildings of wood materials, buildings with two or more floors.

Unframed foundation - for the construction of a bath and other small-sized structures.

Technology of the

device If the work is done by hand, it is better to choose a round shape for the pile. For supports rectangular shape will require special equipment, the use of which increases financial costs.

You can see all the steps clearly on the video.

First, the foundation dimensions are calculated. The calculation is based on the analysis of soil features.

The calculation should be made taking into account the wind load on the structure, the magnitude of slopes and the mass of building materials. For reliable construction, it is important to correctly determine the number of piles.

It's difficult to make calculations on your own, so it's better to turn to professionals.

It should be borne in mind that if the piles are being replaced, new calculations must necessarily be made.

After the calculation is calculated, markup is performed. Further, according to the layout, you need to dig trenches depth of 40 cm.

The width of the trench is determined individually for each project, depending on the area of ​​the foundation, for which the calculation is carried out.

The next stage is drilling holes for piles in the corners and perimeter of the trench. Pits should be located at a distance of 2 m from each other.

The depth of drilling should be greater than the freezing level of the soil by 50 cm. This depth will be sufficient for the installation of a sand cushion.

The diameter of the pit is 1/3 of the width of the belt trench.

When the wells are ready, you can proceed to laying the waterproofing material. To do this, it is necessary to lay ruberoid in all wells.

Now you need to make a ribbon base. First of all, a pillow of sand or gravel with a layer of 30 cm is poured, which will ensure the drainage of water from the foundation.

Then formwork is installed from the board. They are fixed together with nails or self-tapping screws.

Next, you need to make reinforcement using twigs with a diameter of 12 mm. They need to be fastened together with a special wire to increase the strength of the foundation.

Not only the tape base is reinforced, but also reinforcing belt is mounted for all piles.

When the reinforcement is finished, you can start pouring the substrate. First, the cement grout is filled with boreholes.

When pouring the tape base, every 20 cm of the filled cement mixture must be leveled to eliminate voids.

The formwork is poured with concrete to full height. Fill the tape base and piles with minimal time intervals.

If the boring method is chosen, then pipes are installed first, and then concrete is poured.

First you need to pour 40 cm of solution, and then raise the pipe so that the concrete solution gets under the pile, forming the so-called sole. This will ensure a reliable grip of the structure with the ground.

Before pouring the mortar, level the piles.

And after the solution has solidified into the pipes, you need to insert a reinforcing cage, consisting of steel rods, connected by wire, which forms a grate.

The reinforcement frame must exit the pipe to the top edge of the tape base.

After three days, the formwork can be removed and waterproofed with a tape substrate using a roofing felt.

In general, the device of pile-strip foundation with his own hands is not difficult, the main thing - that all work is carried out with the maximum care and responsibility, otherwise the base will be short-lived and may soon need to be replaced piles.

The technology of the pile-and-tape foundation can be viewed in detail on the video.
