Tips for laying concrete blocks

Describe your opinion and fine sand concrete masonry blocks or PGS. After the solution was laid on a few dozen pieces in the first row of the fence, stuffed hand as saying, and the process can be described already.

This information is not relevant for professional masons. Perhaps it is useful to those who want to lay down their own garden of a house like blocks or I - fence.

1. Solution.

For doing its foundation masonry I solution (or solution for first clutch units) - 1 to 3. The solution must be free of stones. Sand in Sift ideal. If the seam is thin - stones can prevent the unit. Kneading in the mixer. Did not much liquid and not thick, so that he could lie down and not drop a block on it. If you use a plasticizer, then add less water.

Also, if the kneading sand buckets 3, then over one hour a solution need not leave - grasped, especially in the heat, as loses moisture. Either it must be periodically stirring.

2. Always use beacons

It stretched horizontally thin rope. Desirably white because at dusk dark color it is no longer visible. And for this you need to put extreme blocks (corner) on the same level. Mark level of extreme blocks better lasers at sunset, when the sun is not bright and clearly visible beam.

Rope beacon better put at a distance of 1-2 mm from the corner blocks. The rope will not only ensure the straightness of brickwork, but horizontally. If this is the first row, as in my case, then there are local deflections of the concrete ribbon, the foundation and in such places need to put more of the solution.

3. Application solution

In previous articles I have used limiting bars 1,5h1,5sm. But now she refused them. Just do not impose a solution to the edge of the concrete ribbon:

Pre-moisten the surface of the concrete (if necessary heat). Concrete draws water from the solution

Applied layer must always be thicker (higher) than the seam already stacked. Blocks hollow concrete part and is pressed in the cavity.

4. level control.

As duplication of the provisions of the block using a short level. Checking horizon (along the block) and its inclination in the masonry. For experienced masons is not a mandatory procedure. But for those who just fills his hand, I think it is necessary.

5. Grouting

Because I decorative blocks, then I fill the void and overwrites the seams at once:

Filling the voids in the vertical seam between the blocks. Once the solution has dried slightly to receive a sponge and washed with water:

The solution contained gravel fraction 1-2 mm. Once washed - they become bare. This allows the seams to merge with the texture blocks.

Horizontal joints also being finalized. Excess solution is removed, and fill the empty space smoothing bar or glazing bead.

The main thing - do not hurry. If you see that the block is wrong. You need to remove it and report the solution. Several times had to do so. Then the tempo gradually grew, hand engraved, either on the job, as they say.

I do not pretend to be professional opinions. This is just my opinion.

Video did not take off because all photos do on a smartphone. But I recommend to watch this video here, where a bricklayer illustrates the process of its work and make comments:

In conclusion, here are a few photos that could make for a portion of the day. While the time taken to fill and clean data decorative blocks.

The view from the side of the road

According to the project only two layers, plus a clutch cover. Above - a wooden fence.

I moved on to the fourth flight. There are empty spaces in the masonry - they'll fill when'll put the first row of whole blocks. It will be necessary to cut off the Bulgarian part of the block and paste in brickwork. It is better to measure the length dobornyh blocks, mark them on the core, numbered (at passage number) and time to saw off.
