Defects on the surface of the foundation plate. Permissible or not?

the foundation of quality is determined not only by its strength and reliability, but also proper geometry.

I already wrote, both had their foundation on the strength of materials at hand. Finally, three days, I finally released him from the snow, and I can appreciate it fully.

Even before construction began, when I studied the information about the foundation of manufacturing technology in all the examples that I have seen, surface slab foundation, with concrete pouring, They were taken in a perfect mirror.

And most importantly, this process takes a considerable amount of time on the entire concrete acceptance procedures.

And I initially wondered how necessary this perfect?

It seems to meThat the only thing that affects a completely smooth surface plates - it was not necessary to level the floor with fine finish.

As for strength and operational characteristics, the flat as a mirror surface, does not play any role.

Your foundation I leveled "by eye" and at dusk (as it can be read here: Acceptance of the concrete together. I will remember it forever.), so We got what we got:

Most of all irregularities left filmThat I was laying the foundation after pouring. But there is a cavityI just missed, and not smoothed.

Of course, if it were possible, I would have done anything better, but the result is the same considered satisfactory.

Of course still need to make a final measurement along the diagonals and vertical drop, but now seen some flaws.

When there is water on the stove, once you see where some nuances. The only thing that catches the eye - it is the accumulation of water in one corner. There is clearly a lower level than in the whole plate.

But the depth of this "puddle" very small, somewhere up to 1 cm.

I think after all the main thing that should not be - it cracks. And all the differences in the range of 2-3 cm only affect future costs for floor leveling. And suffer, and to align perfectly smooth surface, you only hired the builders, to create a presentation foundation.

It is interesting to know the opinion of people who know. Write in the comments. :)
