The master dissuaded from the strip foundation: an extra waste of money. Arguments in favor of slab with calculations

Foundation selection - the main part in building a house. Many people cannot understand which is better: a monolithic slab or a tape type of foundation. Increasingly, builders choose exactly the slab. When he was building his house, the master told what are the advantages and savings on a slab base.

For a strip base, you first need to dig a trench around the perimeter.

Such a base is chosen for the construction of a wooden house, a small building made of aerated concrete, brick (no more than 2-3 floors).

The slab foundation is durable and more reliable. This type of substrate is suitable for any soil, even marshy or peat bogs. You don't need to lay the foundation deep. A monolithic foundation is built even on the surface.

Another obvious plus and economy: there is no need for a sub-floor. And if it is an insulated plate, then the base is immediately suitable for finishing the floor. It also reduces spending.

The slab base technology is simple and anyone can handle it. You don't need to hire a team - that's another savings.

The plate will withstand the movement of the ground. The base will "float" with the ground. Will not burst or crack.

Someone will say that the cost of a monolithic foundation is higher than a strip one. But this is not the case. If you make a recessed strip base, then the difference is not noticeable. If we take into account the advantages listed above, then the slab foundation will be cheaper.

You can reduce the cost of a slab base using stiffeners. The slab is made thinner to save materials, and the strength is compensated for by stiffening ribs. They are made mainly where there will be a heavy load (load-bearing walls).

For a slab-type base, it will take less time and effort to formwork. You just need to fence around the perimeter and pour. Experts estimate the service life of a slab base for 100 years, and for a strip base from 15-30 years.

Of course, a slab foundation is not suitable for areas with a steep slope, unless you level the ground. The basement will also be difficult or impossible to build. But all these minor cons are not so important.

Calculations

Slab foundation will cost 114,000 rubles. for a house 8x7 m. The thickness of the slab is 24 cm. Use composite reinforcement for reinforcement. It is easy to cut with a grinder and weighs less. Does not rust, is not afraid of moisture. Diameter from 8-14 mm. You can knit with plastic ties.

Strip foundation for the same house will cost 150,000 rubles. This is if the width of the tape is 300 mm, and the height is 60 cm.
