Erection of the foundation of the house with walls at right angles
When pouring the foundation, it is very important to consider the angles under which your walls will be located. There are many fairly simple methods for this. You can use the construction level or measure straight angles using a simple triangular ruler. But simple knowledge of mathematics, namely the simple law of Pythagoras, which is used to measure the sides of the rectangular triangle, can also help you with you. Measure the length of one wall, and then the length of the second wall. Remember the rule: the sum of the squares of the legs is equal to the square of the hypotenuse. Enter your measurements into the square and add the received numbers. Then you only have to measure the distance from the end of one wall to the other diagonally. If you got the same amount as in your calculations, then the walls of the house will be located at a right angle. This is a simple rule that helps with independent construction of the foundation at home.
Nevertheless, with a not quite even foundation of the house, you may have various errors in the calculations. Do not forget about it and try to align the surface where you plan to build a house, as well as the foundation itself using the simplest ways, for which you may need only a school line with a right angle, as well as a self -made level from a rope and a load suspended on it, if You don’t have the necessary tools at hand.
