Stages of laying the foundation for the construction of a veranda
At first on Earth, I measured the poor veranda, outlined the place of columns. The distance between the columns should not exceed 1 meter. Using a manual storm, drilled holes to a depth of about 1, 5-1, 8 m. Poured 1 bucket of sand, shed it all with water.
After that he inserted the sewer PVC pipe, where the plastic pipe did not have enough asbestos -cement, no difference. With the help of a water (there is no other) level, he measured the desired height of the poor columns and drank pipes at this level.
It is necessary to calculate the height of the pillar so that the floor on the veranda is slightly lower than the floor level of the house by 10-15 cm. But do not forget that the pillars should be 10-15 cm (depending on which beam you use), plus the floorboard is 4-5 cm, the total pillars should be at least 14-20 cm below the future floor of the veranda.
After he did it, concrete is poured into the pipes, at the same time tamping with reinforcement. And of course unforgettable in columns in concrete reinforcement for stiffness. We wait for the concrete to grasp the concrete a little, we insert the stilettos of the M8-M12, to fix the first crown of our veranda.
