Making the eternal blind area, porch and garden paths. Going "industrial" technology

Fill the concrete porch, blind area, garden path, it runs 3-5 years and appear on the surface defects: potholes, cracks, chipped corners. Why it happens?

Concreting these designs generally use low-grade concrete. It can be strong enough to carry out their tasks, but frost resistance and water resistance is poor. Accumulates on the surface of water, it penetrates the pores in winter freezes and expands. The top layer begins to break down.

How is reinforced industrial floor

Flooring shopping centers, industrial plants and other large facilities have high water resistance and abrasion resistance. This effect is achieve through the use of the topping.

After concreting over the surface scatter special composition (topping) and tested the top trowel "helicopter". Progress does not stand still) But, if you look at the technology, it turns out that everything is new - is well forgotten old.

Hardening of concrete with their hands

Concrete with low water absorption and abrasion-resistant surface makes even our grandparents. Only this process is called zhelezneniem, and instead used the cement topping the highest marks:

1. Concreting otmostku, porch, garden path, or any other design.
2. Depending on the weather and the mobility of the concrete are waiting for 1-5 hours. The surface should not completely grasp. Came, it was a trace only a couple of millimeters - it is time to iron.
3. Layer 1-2 mm over the entire area scatter cement. For this ideal kitchen sieve.
4. Once the cement imbued moisture (became dark gray), rubbing it into the surface of a steel trowel (in one direction).
5. Cement crumbles second layer (lower half) and is overwritten in a perpendicular direction.

Where even the masters often kosyachat

Often heard complaints that the cement cracks over time, fall off, snaps, swells, etc. If you observe a few rules, this does not happen.

We work on a wet base! Cement useless to do when the concrete gained strength. If you are doing this for the first time, small concreting sections.

Remove excess moisture! If the concrete gave water to the surface, it drove the scraper or trowel. When a little overdone base, slightly damp concrete. ND not pour water over the cement. Otherwise we get laitance which bulges with high probability.

Caring for concrete! Construction after zheleznenija more susceptible to cracking (during curing) than conventional concrete. To learn how to properly care for him, I said in another article.
