If to know stages of construction of melkozaglublenny continuous footing, it can be built independently. It considerably will reduce the price of construction as it will not be required to employ workers and to rent the construction equipment.

Instruction
1. Low houses most often build on melkozaglublenny continuous footing. This basis is considered one of the most inexpensive. It is assembly and monolithic. Combined continuous footing is built from strong reinforced concrete blocks BSB (base stenovy block). The main stages of construction of both types of the bases are generally identical, but each of them has features.
2. Irrespective of, assembly it is the base or monolithic, construction is begun with marking. For its maximum accuracy it is necessary to conform to the rule: both diagonals of each block designated by pegs have to be equal. Stages of works following: at first visually examine construction site, define where roughnesses and make soil planning. Then find the most low located point and note it peg. Work is performed hydrolevel. Further, calculate angular points of the base and continue marking.
3. After that start excavation of trench. For melkozaglublenny continuous footing it is enough to dig out of it on depth of 40 cm. The ditch has to be 10-15 cm wider than tape. Earthwork operations can be performed independently or by means of the excavator. The bottom of trench is leveled, using hydrolevel.
4. Make dumping by sand and gravel. The first layer has to be 5-7 cm high. Sand is leveled and condense, previously the passage with water from hose. Then also arrive with gravel, but its layer has to be more: 10 cm. If continuous footing is assembly, start mounting of reinforced concrete blocks. If monolithic – to the timbering device.
5. At first knock together wooden boards, then establish them in trench and connect among themselves. From outer side the boards strengthen obliquely the established bars. Internal walls of timbering close dense polyethylene that will allow to keep sawn timber and to use it further for construction of the house. Then start mounting of armopoyas.
6. Two types of reinforcing rods will be necessary for reinforcing of melkozaglublenny continuous footing: ribbed with a diameter of 8-10 mm and smooth with a section of 6-8 mm. For connection of bars use either welding, or lashing wire. Armopoyas represents grid with cell of 20 cm mounted in two tiers, each of which is connected by vertical bars from smooth armature. Horizontally laid rods have to be ribbed.
7. Further make underpouring. Cement and sand solution is prepared in proportion 1:3 (1 part of cement of M400 brand and 3 parts of the sifted sand). Carrying out solution filling, it is condensed that promotes air outlet. The monolith will gain the fortress not earlier, than in 3 weeks. But it is possible to dismantle timbering in 5-7 days.
