Monolithic surface "Washed concrete." Fill decorative blind area

I'll start by explaining why I had to fill in blind area, if you have not built a wall. Indeed, in the process of building a decorative surface may be stained with a solution or even damaged during unloading equipment or installation materials.

Yes, there is such a risk. From the solution it is possible to cover with plastic wrap. And with the technology - to monitor the situation.

Immediately after the pour of the foundation otmostku I decided that's what: gravel pad under the base extends beyond its perimeter 0.5-0.7 m in. autumn and spring it will saturate with water and do not even frost heave heaving soils appear in the structure during freezing. Therefore, I decided to somehow close the access of surface water into the pillow. Otmostka planned insulated - with a layer of extruded polystyrene foam.

Well, since I had already mastered the receiving surfaces "Washed concrete", the same has decided to perform and blind area in the basement and color - with the addition of brown pigment. Pigment still had at least 5 kg.

At the beginning planned around the perimeter of the foundation. I set the formwork at a distance of 62 cm from the edge of the foundation. This distance is permitted without waste bed extruded polystyrene (59 cm) sheet slitting exactly in half and close to an end with concrete (3 cm). For otmostki purchased:

- f2,5 masonry grid, 100x100, 1200h500 - 50 pcs.

- Extruded polystyrene thermal, 1190h590h50mm - 6 Pack.

- Cement M400 50 kg - 11 bags

Extruded polystyrene purchased by 2 pcs., Moved three times in his car. Cement gained 2-3 bag, the usual pattern for me - on the way to the site.

"Cake" was prepared in the blind area: extruded polystyrene foam, a layer of concrete, masonry mesh, the concrete layer with the pigment.

Next was laying packaging paper, pre-impregnated concrete retarders and dried. And on top of still covered with polyethylene film.

There is shown a blind area portion covered with this paper.

Required condition:

The next day had come off or not to stiffen the upper concrete layer and wash it with water. I did everything as before: brushed metal and plastic brush. Residue washed off with a sponge and water. Ideally this should be done Car wash high pressure.

What has already been laundered - he was laying polyethylene, whatever the concrete does not lose moisture. I watered it every day with water, that he is rapidly gaining strength.

On the other side of the foundation. Each layer is smoothed with a spatula and tamped lightly.

After compaction surface appeared liquid fraction concrete.

Between the insulation and the foundation itself was a gap where a little flowed laitance. In this place had more concrete topped up. Ideally, it is better to zapenit contiguity.

For this you can make technology and monolithic concrete decorative track. No need to purchase paving, road tiles, etc. They are 15-20 years will be ruined, the surface will become ugly appearance due to the destruction of frozen ice in the structure of pavers:

A monolithic track with a surface of "Washed concrete" this picture never give. Even if you fall off a few rocks - these places will not be seen on the background of the overall structure of the surface.

Expansion joints once did. Later propylene slotted disc grinder with stone and missed sealant.

In preparing this article, it turned out that I did not do macro decorative surface of the blind area. Because while when shooting these photos, I did not even think that I would keep this blog. There is only the final photos of the foundation, which is given in the following articles.

The very sight of the surface and will show in the following articles (and I will add here).

Fill blind area - is not all that has been done in the season of 2018, associated with the foundation. It remained a small but important detail.
