The process of building such a fundamental design begins only after writing the project of the entire building. This work should be performed by a professional designer, because the price of one error can affect the entire extension in general. It is the project that contains the characteristic of the design on the basis of which the required number of building materials will be calculated.
The first work is to dig a trench and arranging a pillow of sand. To do this, you need to create markings around the entire perimeter, since it will meet the upcoming location of the load -bearing partitions and the facade section of the construction. When marking, it is best to use a rope, which is easily fixed thanks to the pegs driven into the soil. You can indicate the level of the width of the partitions by pulling another rope in the parallel direction. To resist the future building, you need to increase the width of the structure by 10 cm.
After all of the above, you need to start digging trenches. Since the process is performed personally, it is best to use a shovel. The depth indicator of finely chained strip structure should be 40-60 cm. You always need to take into account the deepening freezing of the soil. It is best to set the sole of the basis below this level by 20 cm. Sand is poured into several layers, with a thickness level not over 15 cm. The next stage is to create formwork. To do this, waterproofing materials are fixed in the side areas of the trenches.
