The foundation for the house. How do I start?

The question is a fundamental foundation in the process of building a house, and on the decisions taken at this stage, all depends on what will happen next.

That's why I think this question is very serious and want to make a reservation:

All the information you read here, I have taken out of the knowledge that already purchased, and All findings are personally my opinion.

And the fact that I am building a house that's right - this is my decision, and I take responsibility for all your actions.

Therefore, it is not necessary to perceive it as a guide to action. You have your head, use it and draw your own conclusions, based on my experience.)

What influences the choice of foundation.

There highlights that it is necessary to take into account:

1. Size, number of storeys of the house.

2. The composition of the soil.

3. The ground water level (GWL)

What I will have a house?

Just want to say that I have decided to build a house without the project and the more calculations. ( I have since construction budget) .Many can me now stoned, but then again I'm not saying I'm right, it's just my choice.

And I decided to do not only for the money.

I believe that the main part of any project - it is a useless stack of paper. And all you need is only the wage-workers, who have no idea what the customer wants. And I for myself all clear)

The only thing that there is a useful calculation of the foundation. But it is, I think, is needed in the construction of 2-D and 3-storey houses.

I will build a one-storey house of aerated concrete, 9x9 meters with a loft.

What is the ground beneath your feet? GWL.

According to science,of course you need to carry out geological studiesBut I, as you know did not bother with it.

Here of course it is important to not that is from above, and what is below.

Even during the construction of roads and digging trenches, I realized that I have a small fertile layer (about 30 cm), and then is fine sand with clay inclusions.

At the same time, dry the sand becomes very denseBut under the influence of water (I looked at the bottom of their trenches along the road), he, it can be said floats.

Therefore prop up the foundation directly on this layer, I do not like not knowing what's going to happen with the seasonal rise of water. And I decided to do the following:

1. Be sure to do the drainage around the house, to remove excess water.

2. Raise the foundation as high as possible by increasing the cushion beneath him.

3. Choosing a foundation with larger bearing area.

Why am I here?

Considering all these factors, I decided toThat I need foundation slab type. But to raise the level of the house only by filling the base with sand, I did not want to.

I decided to make the foundation of the type insulated Finnish plates (without insulation), ie 100 mm plate and stiffeners down 400x400 mm.

All the figures I took based on the examples of already built houses, and themselves rib made with a small margin.

I did the right choice or not, time will tell.

And I had a great and interesting work on the construction of the foundation, where there were so many nuances... Well it as always). Each stage requires a detailed story.

so that the sign up and do not miss the fun ...
