How To Determine Concrete Strength On Site And Business Idea: House Survey For Their Buyers

A laboratory destructive method is used to determine the strength of concrete. This is a method based on the graduation and the dependence of the indicators during deformation of the material to its brand strength. Usually, a "cube" is cut out of the concrete body at the facility and the research is carried out in the laboratory.

Probably everyone has seen the cut pieces in the pavement of new asphalt - they are examined in the road laboratory using the same principle.

But the engineers were able to enter 100 of the obtained values ​​of the destructive methods into a mobile device called a sclerometer:

This device is called Beton Pro Condtrol. There are other models as well.

The device contains strength values ​​not only for concrete, but also for other materials. The device uses impact strength analysis method.

The device has a younger brother - Condtrol Beton Easy:

Its cost is 15 thousand. rub. below. But there are no such tuning possibilities for obtaining more accurate indicators. How to use the device - see a small video:

The cost of the device is not small and for acquiring only for yourself, in order to find out the strength of the concrete of the poured foundation or other concrete elements, it does not make economic sense. And the meaning appears in this case ...

I found out about this device in Sergey Petrusha's instagram (Stroykhlam channel on youtube). I have been following his activities for a long time. As I understood, he found a niche in construction services - surveys by express methods of houses before buying. Examinations not only with endoscopes with inspection of floors, ceilings, roofing cake, etc. But the analysis of the strength of concrete foundations by this device, analysis of ventilation with an anemometer and air quality (for phenols and solid pollutants), legal work with documentation on an object. The list of his services is here: http://domopodbor.ru

Someone will say that such work requires accreditation as a mobile laboratory, regular certification of devices. I think this is not a distant future for him. At one time I installed and supplied laboratory equipment, including for mobile laboratories. This service can grow into such a business. But which private home buyer needs these pieces of paper? The minimum task is to find out about the critical moments in the house and make a decision - to buy or not to buy!

Also, devices can be rented. But I would not give them to untrained hands - this is not a puncher.

In the advertisements, I saw only a survey of houses with a thermal imager (in winter). And I have never seen such complex services anywhere. Sergey works in the Moscow region, and people in every city need such services when buying ready-made houses and apartments under construction. In my opinion, it’s not a bad idea at least to earn extra money in any city.

From the legal form of activity - self-employment. 4% tax on work with an individual entrepreneur and 6% with a legal entity. You do not need to open any IP. Do not go anywhere; yj, registration through the website or mobile application. Type of activity: technical services. At the expense of licensed activities - this is a question of how to correctly draw up an agreement with a client. For example, it may sound: searching for defects and violations in the technology of building a house, and not testing materials and analyzing the microclimate of the premises.

If someone has an interest in this idea, write in the comments, then in subsequent articles I will compile a list of devices (with links to them) for studying the nodes and parameters of the air at home.
