Pouring concrete ribbon on top of the foundation plate,

Let me remind you that the height of the permanent formwork for the slab-foundation of my 45 cm, and the thickness of the plate - 30cm. 15 cm of my project, I planned to fill the tape on top of the foundation.

What is it for? The logic is as follows: the construction of the house with a roof box, I will not be able to complete on their own in a single season. This means that the lower bound of the first row of masonry of aerated concrete will get wet, and in the winter to collapse.

This applies probably all materials, collect water in their structure. Although frost aerated concrete and reaches F100 indicators (cycles freeze-thaw), wet material can be destroyed within a few years.

So, the material of the walls must somehow be protected from water that will accumulate on the foundation. Decided to raise the level of the concrete masonry reinforced tape. Concrete not absorb water as porous materials. And this method will increase the visual height of the basement to the optimal 45 cm. Get the foundation plate, bowl. For this advance has provided permanent formwork height is 45 cm.

One week after the fill plate began to build on top of the formwork board 25s. Decided to pour their own, do not induce truck mixer. Concrete must be not much, and its volume is more difficult to calculate.

I decided to increase the strength of concrete additive Polyplast-1MB. According to the manufacturer, the strength of concrete increases by 15-20%.

I have marked all of the project, in accordance with the location of walls, nylon rope and pulled on it installed formwork.

Between the board (formwork) and the plate was slit. That I would not have emerged concrete - zapenil gap around the perimeter. The compound was obtained at a foam bottom formwork fixation. A vertical position of the top board fixed the bar, the connecting screw through the board, which was fastened to the layer of polystyrene permanent formwork foundation.

Here in the photo it is clear that already decided to try to fill in a small area:

I poured on level ropes stretched in accordance with the plan arrangement of the walls.

Many of the tape, or grillage base (call it what you want) - spread brick. This does not increase the strength of the whole structure in the bond with the base. Brick can be destroyed, frost it in such conditions - a couple of years. And this tape reinforced concrete durable, so does not reach the water, as a complementary rib foundation. Just increase the height of the base and prevent the wetting of the masonry. Solved some problems.

By the way, about the frost resistance of brick and aerated concrete in the canal in their StroyHlam instagramme posted short roller, which shows disintegration of bricks in the brickwork or concrete between the foundation and the masonry under Laying nets. Apparently, after he took some water and stood for a couple of years crumbled. Here are screenshots of this video:

No comment. While skeptics will argue that it is the quality of the brick. Of course, you can use fireclay - then this will not happen. What for? In general, what the builders are doing the brickwork - a topic for another article.

He completed the formwork on the whole basement area. Boards mobilized from the boards that were pouring from the fence tape and then propped up permanent formwork foundation.

Filled tape for two days. This is in view of the formwork assembly (it spent most of the day). So I get almost monolithic.

Two days later, I began to dismantle the formwork at the location where the tape filled on the first day. A little early. We had to wait for another 2-3 days.

After the rain water accumulated within the cup-base. For what would the water run for its perimeter, I had a system for pipes from HDPE-pipes that were laid across the belt. But now they are closed until the shuttering board. And also provided several of the same tube, through which water can drain outside the foundation.

Later puncher has altered the flow of water in each location. On the formwork dismantling spent a couple of evenings. Next, it was necessary to fill the blind area. Why now, and not after the erection of walls - read the following article.
