What is cheaper and easier to build a basement. Concrete blocks or CFC?

Many are convinced that their house should be a basement. To deploy a furnace, workshop, pantry, laundry room, cellar, sauna, cinema, etc. Options for how to use the space much. Not all at the design stage realize that the cost base is at least one third of the value of the house.

The pleasure of owning a "-1" floor is not cheap. But if you do decide to take this step, then the technology to build a basement? What is the foundation for its walls and the type of wall material will be optimal in terms of simplicity, price, reliability and speed of erection?

I will write their opinions and point out short numbers on the basis of those examples, which are seen.

Foundation

I believe that the slab foundation under the walls of the ground floor - it is easier and more reliable, but there is often a slight overrun of concrete and reinforcement. Ideally, you need to consider a lot of your home and to take into account the carrying capacity of the soil under the house. And only then make a decision: the tape or slab. If in doubt - clearly do slab foundation.

It can be made in design as in the photo: rail fittings on the walls in 4-6 bars of increased cross-section, and on the floor to leave a layer of reinforcement as a grid. Under floor lay Epps. If the house is planned to build during the season, the frost heave in the basement and floors will not be enough this reinforcement.

If you chose a tape, then later all the same it is necessary to fill in on the ground floor. Savings on the tape there, but only slightly.

The walls of the PBS block

The quickest and easiest way - is the construction of the walls of the FBD blocks.

Brought blocks hired crane. A team of solution and kneaded for a 1-2-3 shift erected walls. The only thing is you need - is to calculate the length of the plinth under multiplicity FBD blocks and a standard PC boards length. Although, if you get the plate PB series, then you can order any of their length.

The blocks FBS inexpensive. Honey is their delivery based on 1 pc. But let's say to our village that 5m3 concrete mixer that dlinnomerov with PBS will cost about the same: about 5 thousand rubles.

On top of the masonry walls of the FBD blocks necessary to make Laying nets. And you need to fill it with high quality and as horizontal as possible. This would allow equalize the height difference at the corners that would slabs laid horizontally.

Piping and leveling the horizon, made bricks, I do not accept for a quality solution.

monolithic wall

If you do not have an industrial casing, the solid walls can be built only by applying-layer fill. It is too long. One - difficult to constantly rearrange the formwork. If you fill each layer imported concrete, the concrete whenever needed. If samomesnym pouring concrete, one layer does not overpower even crew for a working day.

Yield - make cold welds in a single layer. To do this, you need to be more qualitatively reinforced walls. Reinforcement in a basement need a lot.

My neighbor across the street in the CHT poured himself just such a solid base and plus made a monolithic ceiling on it. It costs in the amount of about two million rubles. Given the fact that a lot of what he did.

The video below confirms his words:

Want to find out the cost base of CFC blocks? See a short video below.. There's at least prices and the 2016, but the difference in the price level, the speed of the construction between the monolithic design of the FBS and the blocks immediately understand:

As seen, on a tape foundation plinth size 10x12 m of about 100 units FBS overlay of the plates are now cost at least 600 thousand. rub. Are you ready to allocate the same amount and get the desired square - you decide.

I initially refused the basement, knowing the order of these costs. Write in the comments, how much money you have spent in the basement (if you were building a house with a "-1" floor).
