How to make a cellar under the slab. Important moments of my experience.

Only after I finished my cellar I really imagined what awaits me ahead, With the main works of the foundation ...

The summer was dry, but even so, dig a hole under the cellar of 0.7 meters, I came across the water. Perhaps there are methods and how to make the cellar in the presence of groundwater, but this one was definitely not possible.

Therefore, based on their needs, I decided to stop at this depth.

Under these conditions, if we add the 0.7-meter pit beneath the cellar, plus 0.5 meters pad foundation, plus 0.3 height of the foundation a yield of about 1.5 meters height of the cellar. As I have I am talking here, it suited me for my purposes of its use.

Since groundwater in the area penalty can be up to half a meter, walls and floors, I decided to make the most impenetrable, ie poured concrete.

I slept first bottom layer of gravel, then spread a film and laid armature.

Film postelennuyu to the bottom, we need to concrete fast did not leave moisture in the sand, and it normally stood.

Pouring concrete I made in three stages:

1. First bottom.

2. Then, to the level of the bottom wall of the pit.

3. And after filling pillows under the foundation, walls refilled almost up to the plate level.

A very important point.

The walls of the cellar and the foundation does not have to come into contact with each other, and even more do not have to be filled in a single monolith, since all this construction is non-uniform shrinkage that It can lead to tragic consequences.

Therefore, cellar and a stove, I left a gap between the walls.

Wall I poured in two stages for several reasons:

1. At this point I finally e esch did not know what height will cushion the foundation and, accordingly, it was not known what will be the final height of the cellar.

2. When filling the high walls needed serious work on installing a solid casing.

Even the pouring height of 0.7 metersSeemingly solid steel formwork and disperse I had to urgently all to strengthen and further inflate. Fortunately, everything worked out.

Therefore, one should not underestimate the concrete mass and strength of formwork to take seriously.

Concrete I bothered myself with the help of a concrete mixer.

Even if you have appliances that work was given difficult given the fact that he did it all himself, and a little help my girlfriend.

The final stage was the ceiling.

It was made of a thick board of 50 mm., And it has poured slab foundations.

That is, as already said, the very walls and ceiling are not connected with each other and were separate structures.

In the end, after all the work, I was concerned about the water tightness of the structure.

To do this, I did the following:

1. During the manufacture of concrete added added a special supplement to its waterproofing.

2. I missed all the joints with mastic asphalt and concrete from above with liquid glass.

Well, all this will help, will see in the spring, when the peek into the cellar.

Snow this year, enough to test will be good ...
