The blind area around the house is by no means eternal. The day may come when, under the influence of external factors, it will begin to collapse. Worst of all, the blind area is affected by ordinary water, which falls in the form of rain and snow. It is she who leads to the appearance of the first cracks, the size and depth of which are aggravated with each new winter. In order to protect yourself from its destructive effects, you should do one single trick.
What you need: tape measure, marker, diamond disc, grinder, frost-resistant concrete sealant
The main mistake of many owners when creating a blind area around a house or outbuilding is ignoring the creation of expansion joints. They are needed so that under the influence of external factors a web of small cracks does not form on the concrete. However, you can’t just take and cut recesses in the material with the help of a grinder.
First you need to mark up. Expansion joints are always made on the blind area across with a step of 2.5-3 meters. It is highly desirable to do everything so that the seams divide the blind area into equal parts. To achieve this effect will help systematic work with measuring instruments.

Next, you need to work hard with the grinder. A diamond disc is used to create seams. The cutting depth must not be less than 20 mm. During work, be sure to use eye protection and a breathing mask. After the seam is cut, it must be rinsed with water. When the place of work dries up, it is necessary to fill the slot with frost-resistant sealant, removing all unnecessary.
