In this review will share with you the technology of making concrete piles for the gazebo.
The diameter of piles — 250 mm, depth — 1.2 m.
First thing, armed with a shovel, it is necessary to remove the top vegetative layer (topsoil).
The author decided to place the piles, stepping back a small distance from the edge of the gazebo to the attachment of the waist was not necessary on the vertical posts of the pergola.

Start to work
The next step is to drill 6 holes to a depth of 1.2 m. This can be done by using a homemade drill.
For the reinforcement of piles, the author uses rebar with diameter of 8 mm.
Each pile will require three rods of rebar. For a fastening of bars used rolled steel wire with a thickness of 5 mm.
First wire we produce clamps of triangular shape, which will bond together the bars of reinforcement.
Then make six frames. For each frame we put on two clamps and fasten them with binding wire.
For fixing timber bottom trim, the author has prepared a stud diameter of 22 mm.
To stud is better held in concrete, the author put them in the washer, fixed with nuts.
The preparation of the concrete mortar
To prepare concrete grade M300, need 1 part of cement M500, 2 parts sand and 2.5 parts gravel (proportion — 1:2:2,5).
Of water take 1/2 part of the norm of cement. Also, be sure to use a plasticizer. It is better to dissolve in water.
The sequence of laying the following materials: water with a plasticizer, gravel, cement, sand.
The installation of piles, concrete
On the bottom of the wells is necessary to pour a little sand. Then installed the metal frame of the valve.
Then fill the hole prepared concrete solution.
It is highly desirable to profibrinolytic concrete deep vibrator, which not only expels any excess air from the solution and condenses it.
For serving the above ground part of the pile, the author uses a framework of welded metal mesh and roofing material. This framework is very simple to manufacture.
When the pile is almost completely filled with concrete, install the stud to the previously noted depth and fill with concrete the rest.
It is extremely important to install the studs vertically, or put then the lumber of the waist will be problematic.
Filled with concrete of the pile leave to dry for a week.
Remove the outer formwork and processed protruding above the ground part of the pile (only the top) of bituminous primer.
