Any house must be built on a solid foundation. Its durability depends on this and in order not to make the most common mistake, it is important to know how to correctly make the markup for the foundation.

Before starting the layout work, you must settle the issue with the project documents so that:
When drawing up documentation and a project of a house, not only the texture of materials for construction is important, but also compliance with the parameters. With the slightest inaccuracies in the marking of the foundation, the likelihood of erecting a structure different from the project increases.
Next, proceed to mark the first wall. To do this, you need a string or cord, pegs, tape measure and, ideally, a laser level (you can do without it).
There are several ways to create a right angle. We will cover two main ones.
In order to build a right angle, let's recall the Pythagorean theorem.
In order to make a right angle between segments A and B, add the squares of their lengths and calculate the root of their sum ..
. The resulting number will be the length of the diagonal connecting these two segments. It is quite easy to calculate with a calculator.
As a rule, for marking the foundation, the length of the sides is taken such that when calculating the root, an integer is obtained. For example: 3 x 4 x 5; 6 x 8x 10.
Now let's try to do it practically.
First option: The rule of the golden triangle
For example, consider how to mark a rectangular foundation with dimensions of 6 x 8 m.
The first cord was pulled.
To do this, measure 4 m from the point of intersection on the first twine, and 3 m on the second. We put marks in these places in any way.We connect the marks and measure the resulting hypotenuse with a tape measure.
Put the lengths of the sides of the future foundation 6 m and 8 m on the cords, and put notes.
It is not necessary to fasten the diagonals at the intersection.
We fix the third corner, using a peg, and the first angle becomes right
When marking for strip foundations, it is imperative to do the margin of the length of the walls is about 1 m, since laying the foundation involves digging a pit, and when installing the stakes according to the exact dimensions, they will fall when digging.
When marking this foundation, the above length margin is not needed, and its installation is much more difficult.
Marking is done using a two-tier raffle, where the lower tier is the level of the pillars, and the upper tier is the level of the grillage.
It is made the simplest in a way - we build a rectangle according to the size of the foundation according to the above theorem
In general, there is nothing complicated in marking up a slab foundation with our own hands.
The issue price is the cost of a cord, board, or pegs.
