Step 2. Preparing a trench for the foundation. Dig a trench 30-50 cm deep according to the markings. Fill the bottom of the trench with sand, pour water and tamp. On sandy soils, the sand layer can be 5-10 cm, on clay and loam soils - at least 15 cm.
Step 3. Installing the formwork. The formwork is made israel mobile database edged boards at least 25 mm thick or from OSB boards. The height of the formwork above ground level should be at least 20 cm. The boards are fastened into panels using bars, sharpened on one side. By driving the bars into the bottom of the trench, the panels are installed. The boards are connected at the corners to the outer corners, so that it is easier to remove them later. You can additionally pull the outer and inner parts of the formwork together with boards. On the inner side of the formwork, a line is drawn along the level, along which the concrete layer is leveled during pouring.

Step 4. Reinforcement. The foundation of a permanent greenhouse is reinforced with a steel or fiberglass rod Ø12 mm. It is laid in two rows and two levels with bandaging at the intersections. Steel reinforcement is tied with special annealed wire, fiberglass - with plastic ties.

Step 5. Pouring concrete. The volume of concrete even for a small greenhouse is quite large, in most cases it is easier to order a ready-made mixture. For self-mixing, you need a concrete mixer. First, pour cement, sand and crushed stone into it, mix, and then add water. The ratio of components is 1:2:4:8. Mix the concrete until it is homogeneous.
The finished concrete is poured into the formwork and leveled. To remove air from the concrete, it is punched with a special vibrating compactor or repeatedly pierced with a reinforcing rod. The concrete is leveled in the formwork according to the mark and the surface is ironed (sprinkled with dry cement).
