The foundation for the house of aerated concrete

Thinking about how to build the foundation for the house of aerated concrete, should be familiar with the basic characteristics of the building material.

can paint a very long time its main virtues.

But you should definitely call the shortcomings - the susceptibility to any deformations and shifts, fragility, hygroscopic.

tape and pile foundations

monolithic strip foundation under the house of aerated concrete can lay in different ways: small recessed manner or vice versa (below the freezing point of 20-25 cm).

The first option is suitable when a small one-story house built on heaving soils.The second case is recommended for two or more storey cottage.

In preparing trenches is important to preserve the strength of the walls.In cohesive soils, and can not install the formwork, because they perfectly fulfill its role.

Care must be taken, so that the trench for the foundation is not monolithic leaked water.Primer is recommended to dispose of the hill side.

not always possible to prevent water seepage and drainage is necessary to equip.The greater the depth of excavation, the greater should be the gravel cushion on his bottom.

to build a high-quality foundation on the sides of the trench recommend installing panels that are bursting inside.Simultaneously with them mounted formwork.

should be possible to get into the water feed in the future, after putting on a sand cushion and sides waterproofing.

can use the familiar for all roll materials (roofing material, based on polyethylene film, and so on. D.).

Sometimes, instead of a monolithic tape choosing rubble foundation for aerated concrete.Stones of a certain size must be chosen in advance.The density of the solution should allow to sink them without tamping.

Tape base metal reinforce reinforcement frame.

recommended to use wire with a diameter of 8-16 mm, connecting the longitudinal rods crossbars every 25-40 cm (it is necessary to adhere to the constant step).

To remove the formwork can be only after 7-10 days.The tape is covered with matting, straw or burlap to protect from the sun.

In a particularly hot time of the concrete periodically sprayed with water to prevent cracking.

Not less popular pile foundation for the house of aerated concrete, which involves the drilling of a certain size.However

permanent soil horizontal movements it is not suitable because they do not provide sufficient stability and reliability.

Piles starts to tilt, and the house will slowly sink.And this process will occur unevenly.

advantages of pile foundation called the high speed of construction, simplicity and efficiency.

To calculate the number of piles to be installed on the perimeter, it is necessary to take into account the operational load by all partitions.

As a rule, they are mounted in the following locations:

• The entire perimeter - through 1-1.2 m;
• Under the load-bearing walls - every 1-1.2 m;
• in the corners;
• At the intersection of walls.

drill wells not exceeding 30 cm in diameter, can be their own hands.

Using the tool with lengthening bar turns to reach a depth of 4.5-5 m. When you need a large number of wells is significantly greater than the diameter, rent specialized drills.

Erected pile foundation of aerated concrete by the same rules as the belt.

consider several features related specifically piles:

1. for their manufacture should be prepared roofing material, acting as a kind of permanent formwork;
2. From roofing fold pipe suitable for the diameter of the excavated trench;
3. Each pile should protrude above the surface at 20-25 cm;
4. pipe portion located on the surface and wrapped in one layer of roofing material and securely twisted wire;
5. Inside the casing make a small cage of reinforcing wire, consisting of 3-4 vertical bars connected by cross-beams every 40-50 cm;
6. Vertical bars make a projection of 2-3 cm, to connect them to the raft;
7. Poured concrete vibrator and compacted.

can build a similar foundation for the garage of aerated concrete, instead of deep foundation piles having equipped small monolithic pillars.

They also reinforce and make the bottom of the small expansion, reducing pressure on the ground.

slab foundation

most optimal in most cases considered slab foundation house of aerated concrete, erected on all types of soil.

He called floating and moving together with the soil.

This house is situated on a kind of "flesh", without experiencing severe pressure on the walls, causing them to lose the base, prevents local deformations.

distributed under the whole house, the foundation slab reduces the pressure on the ground.

Over time, the buoyancy decreases and the house feels more confident.Excluded are cases where the frame sags and begins to go arbitrarily.

downside is the price, which is higher than other types.

To build a foundation for the garage of aerated concrete may not be cost-effective and practical.Indeed, in the future, for example, will not be able to dig a hole, and so on. D.

This base is a continuous reinforced concrete slab with a bound inside the reinforcement cage.

ground part will act as a sub-floor.That is why it is necessary to insulate well and seal the monolith on all sides.

To build the foundation for the house of aerated concrete in the form of a monolithic plate can follow the following plan:

• In the dug trench poured sand drainage bag, carefully tamped and leveled;
• top of it put a layer of roofing material and vapor barrier film unidirectional;
• put on top of the waterproofing foam insulating layer, such as PSB-35, which is fixed with adhesive tape, glued over all joints;
• Set spatial reinforcing frame;
• poured concrete solution.

Before you build the foundation slab of aerated concrete for the bath, you need to think it over and decide whether all cost-effective material and moral costs.

Each of the above grounds has its own disadvantages, pros.

But every developer has to make a choice individually, based on the characteristics of climate and preferences.Do not be amiss to expert advice.
