How to calculate the foundation?

The construction of any house always begins withlaying of its foundation. This is the basis, without which the house will not fully exist. Calculation of the foundation - the procedure is time consuming, requiring maximum concentration and attention. After all, if it is a pledge of construction, you need to expect everything accurately and rationally (in terms of building materials).

By the time you are going to mortgagethe foundation of the house, you should already have a phased plan, a house project. This procedure for cost can be equated to a quarter of the cost of building the entire house. Therefore, even with the purpose of saving costs, it is worth taking care of everything in advance.

Why do we need a foundation? This is an important part of the structure, because due to it the load on the ground is distributed evenly.

How to calculate the foundation for a house

There are several types of foundations for the house: belt (the most popular), columnar, tiled, and also the foundation of shallow burial.

Our recommendations are suitable for all typesbut it is important to remember that your construction project is what you need to be guided by. Decide on what kind of foundation you want to lay, and proceed with the calculations. The basic data that will be needed to calculate any type of foundation are given below.

First of all, it is necessary to conduct an in-depth analysis of the site on which it is planned to build a house. To do this you need:

Find information on the level and depth of occurrence of groundwater and groundwater.
Determine the type of soil on the land.
Be aware of how deep the ground freezes.
Get information on how much "crushing" the building on the foundation of the house.

Internet resources now offerautomated calculation of the foundation, including the costs of materials and finances for the construction of a house or any other structure. For example, on the site terem-dom.ru you can use the base calculator. All you need is to enter the primary data (length, width, depth of foundation and walls of the house, the cost of 1 kg or 1 unit of building materials, the number of levels, bars, etc.).

But it is important to understand that some errors in such calculations can be made. Therefore, these calculations can be based on both approximate and repeatedly verified.

How to calculate the size of the foundation

This instruction is suitable for calculating the parameters of tape and other types of foundation.

It is worth saying that to calculate the dimensionsthe foundation will require knowledge of mathematics and physics. It is necessary to make with great accuracy all measurements on the tape - the length, width, depth of the foundation. Such calculations should be included in your architectural design. And they depend on the size of the plot on which you want to build a structure, the number of rooms and floors in the house and other factors.

How to calculate the load on the foundation

This procedure consists of two main phases - calculating the bearing capacity and calculating the deformation of the soil. And if the first phase can be calculated independently, then

the second is strongly recommended to produce ina team of experienced specialists. Yes, it will be additional costs, but only so you can be sure that your foundation will serve for a long time and reliably.

The calculation of the bearing capacity is made according to the following plan:

Determine the weight of the house, taking into account the load of snow,interior elements (interior decoration, walls, windows and doors, roof, stairs, furniture, household appliances, the maximum number of people who will be in the house and any other elements), and also we need to know the level of foundation pressure on the ground. All parameters and approximate weight can be found on the Internet, for example, on the site builderclub.com.
We calculate the size of the foundation, which we need to build.
We perform correction of preliminary calculations.

How to calculate the volume and depth of the foundation

To calculate the depth of the foundation you need the following data:

soil quality at the construction site;
level of groundwater occurrence;
house pressure;
freezing of soil in this area.

These are the basic parameters. Evaluating them, you can determine the size of the foundation and the consumption of materials for it. Also, you will need a house project, which should be your plan of action.

How to calculate concrete, cement and reinforcement on a foundation

Help in this matter can online calculatormaterials for the foundation for both internal and external walls. When we have already calculated the size of our foundation and know all the parameters, we can start calculating the materials.

There are many sites that offer costing services for material. You can use the following sites:

webcala.net - on this site you can calculate the costs of all materials, including beams and other fittings, water, cement, sand, crushed stone, and even the number of machines you need to pour concrete.
allcalc.ru - this site offers to calculate the amount of concrete that will be needed, based on the perimeter of the future structure, its height, width and brand of concrete to be used.
betonocement.ru - on this site you can find out how much cement, sand, gravel and water you will need to produce an installed amount of concrete of a certain brand. In order to do this, we add concrete volumes and brand to special cells, and the calculator does the rest.
zhitov.ru is designed specifically for the calculation of reinforcement for the foundation. Here are two options for calculating the reinforcement: the first calculates the weight, volume, weight of 1 m and units of the rod, and the second - the length and the remaining parameters. The difference between the two calculators is that one of them calculates according to the known length of the armature, and the other - by volume. Remember that for different types of foundation, different amounts of materials are needed, so clearly follow your architectural plan.
