4. concrete stamping

Made using forms that stack neatly and held a press rammer in their area, hammering in concrete form:

To work on a large area need some form. One can do if you make garden paths or blind area.

Process tamped indentation forms:

Dent forms can and feet, but if the concrete has sufficiently grasped, it will not help - the pressure from a person's weight is less than from the blows compaction tool.

Where is the line in the figure stamped bad - you need to walk through an angle of spatula or a special roller.

Three days later, after a set of concrete strength by the amount of 70% - wash separator. Brushes or water pressure - road striker:

The important point is to create expansion joints. Winter may cause cracks due to thermal shrinkage or swelling of the soil. That this is done in a scheduled place and in a straight line - grinder cut seams 2/3 the depth of the concrete:

Or stamping process to make a special spatula groove in the concrete:

5. Application of the protective coating

Ideally, the concrete surface can be treated with concrete impregnation to further increase its strength. Make industrial floors drenched surface. Although fixer has increased the strength of the concrete.

Treat the concrete can be, for example, this impregnation:

Or apply polyurethane varnish, which will give as the impregnation of the above - the effect of wet stone. Examples below:

Similarly, one can create forms the decorative surface and vertically on the pillars and the fence.

But nothing lasts forever, especially in the Siberian winters. It may also happen that when the concrete was of poor quality, the top layer begins to peel:

There is another drawback. Whoever did this surface under the playground for your car, writes that scratches its winter spiked tires of his car. I believe that such a surface is not suitable for parking place. It is better to do such a surface where there is no permanent and severe stress: walking paths and blind area.

And now, a brief count. You need to buy tools, forms and supplies.

- tools (spatulas, trowels, rammers, rollers): ~ 10 000 rub.

- Fixer and separator: ~ 3500 rubles.

- Forms (stamps): ~ 15 000 rubles. (Two forms)

This is without the cost of sand and gravel on the pillow, concrete, rebar, formwork. My opinion, if they do something on this technology in the home, then in a large area or length of the tracks. Because tool costs in the cost of 1 m2 surface has a sufficiently high proportion.

If you take the cost of 1 m3 of concrete for 3500 rbl., That on a platform of 30 m2 and a thickness of 15 cm is necessary to ~ 4.5 m3 of concrete. This is 15 750 rubles. Plus shipping, if you do not get mixed up. Frame: let it be in the range of 3 thousand. rub.

In view of the tool and other consumables costs will be about 50 thousand. rub. 1100 p. / M2

Perhaps the optimal cost, less complexity, and similar are not the worst kind, lay paving vibrocompressed:

Price from 650 rub. / M2. Manufacturers provide a strong guarantee. And there is no risk to spoil anything. This material is always possible to shift. Even replace some items.

On the choice of materials for playgrounds and paths discussed in the next article.
