How to build from gas silicate blocks
Start by marking the future walls. Select the main 4 corners of the future house and mark them. Be sure to check the equality of the diagonals. Blocks should protrude approximately 5 cm relative to the foundation or plinth. It is not recommended to stack the blocks in the same plane with the foundation. Otherwise, moisture will penetrate and leak into the foundation through the joint. Next, you need to tighten the threads in the corners. Locate the wooden blocks in advance and hammer the nails into them. Drive them to the ground at a depth of 20-30 cm and tie threads to them. The final alignment must be done with two spacers. Gradually tighten them to the desired position of the thread.
After that you can start laying the first row of blocks. Do not forget about waterproofing. For this purpose, it is recommended to use reinforced roofing material. Fold it in half. Lay the material under the first row of blocks.Only after that you can engage in stacking blocks. In this case, you will need a solution. Knead it in a ratio of 1: 4 cement and artificial sand. The result should be a practically dry solution. Otherwise, you will not be able to level the block, as it will constantly sink under its weight on the “soft” solution. For the block, be sure to make two “tracks” from the solution. They should be located along the edge of the block. The height of this track is 5 cm.
Use a rubber hammer to level the block horizontally. Initially, 4 supporting corner blocks should be placed. The curvature of your future walls largely depends on their installation. After that, you can proceed to stacking all the other blocks. The second and subsequent rows are done in a similar way. Between themselves, gas silicate blocks can be fixed with a special glue, which is sold in almost all hardware stores.
