The geometry of my foundation. Is it possible to enter the tolerances without special equipment?
it was for me, probably the most exciting moment because it sums up the results very difficult and time-consuming work. And from the results that are obtained depends on the fate of my building.
Though in the manufacture of formwork all tested ten times, I realized that at the time pouring concrete can be offset.
A major question was related to the fact that in all the measurements I used not heaped up levels, and a simple tool: aqueous and bubble level, and tape measure.
Parties and diagonal.
Of course you want to your house was perfect in all respects, side smooth and straight angles. But in practice, it certainly can not be achieved. But the main thing is not necessary.
I certainly was wondering what are the possible tolerances in the size of the sides and diagonals of the foundation? And I was surprised that I did not find any specifics on this issue.
And most interesting is that compliance with these tolerances need only to have to be able to put the cabinet in the corner of the house (roughly speaking).
Although I have always thought that all building regulations are associated with reliability and safety of the structure ...
In general, the minimum tolerance, which I read, was 15 mm. Measure the size of its foundation, I received the following:
The measurements were performed using a tape measure, and admit the error of 5 millimeters. But while I was in kept within the norm.
And the most important thing that all this can be corrected even when the masonry walls. Since my house walls are of gazoblokovThen slightly shifting them in the right direction, you can achieve almost ideal result.
So, one hundred special accuracy linear dimensions of the foundation is not required.
plate plane and swings sides.
Here I had more doubt. Considering that when pouring concrete slab foundation plane I leveled to the eye, the result could get weird.
I already wrote about defects in the surfaceWho are not particularly worried about me. For me it was important that in places the walls of masonry were permissible elevation.
It was necessary to meet the 30 mm. This is precisely the difference between the minimum (20 mm) and maximum (50 mm) thick masonry seam of the first row of gas concrete walls, by which I can align all the shortcomings.
Measure all laser level
Per control points I took all the corners of the house and the intersection of the outer walls with inner. In these places, I put units for convenience and waited, when it will be darker.
As a result, it turned out very well:
All variations were within acceptable limits.
Output.
Actually I wrote this article is not for to urge you to measure all around and on the eye. On the contrary ...
If you have the opportunity to use professional equipment, the be sure to use it.
And if you have only public funds, the rule here is one:
Scan all many times, and then only to do, and then another check again!
