construction of a private house always begins with the preparation andpouring the foundation.Construction of foundation of the house - one of the most important and crucial stages of construction, it requires maximum attention and care at work.
During the construction of a residential building, you can use the following types of foundation:
to determine the type of construction fits a particular type of foundation.For example, a pile needed in the case where the soil in the area is weak enough to arrange it in other types of foundation of the house.
Strip foundation is good that it can equip in most types of soil without extra preparatory work.
If there is "floating" ground - the so-called sand or quicksand, consider using solid or slab foundation.
Most erecting country houses selected strip foundation.
Preparation before pour the foundation under the house is important.At this stage, you need to make a layout plot drawn up according to the foundation of the house before the drawing.The depth and thickness of the base, its location in the area does not depend only on the terrain, but also on the composition of the soil.For example, clay or marshy land require a pile foundation, unstable ground - monolithic foundation and continuous footing in the presence of suitable soil mixed.
marking scheme foundation
layout is carried out using ropes and pegs.After selecting the type of foundation and conducted in accordance with the layout drawings, you can proceed to the organization of the foundation holes.For pile foundation with piles circular shape is necessary to use a manual or electric drill, tape - a shovel and a drill, if there is no possibility to use a special technique.For monolithic base would require strong construction equipment.
After marking the area can start to arrange the hole for the foundation.For greater strength of their depth should be below the frost line.After pouring the foundation usually settles, and to prevent cracking or any other home base strain can, if each hole build a sandy base.To do this, the ground at the bottom of the hole should be compacted on top 15-20 cm pour sand shed with water and well-compacted.
number of concrete solution for the pile foundation can be calculated as follows: support area (bottom of a hole) is multiplied by the height of the pile.Under the area of one support column refers to the fourth part of the diameter of the hole done in the ground in the square, multiplied by 3.14 (1 / 4πD2).A pile height is the sum of the hole depth and length of the pile, which will be above ground.
Pile - circuit device
Prepare a concrete solution should be in such an amount that it does not remain after the completion of construction works.First, the hole is filled with 10-15 cm. It fits fittings - metal pipe or more metal rods with a minimum thickness of 1 cm. Reinforcement will give additional strength to the foundation.After placing the reinforcement in the concrete prepared holes gradually filled up to the top.
At arrangement of strip foundation to advance the marked area equipped with trench depth below freezing.Their width should be no more than 50-60 cm.
Before you pour the foundation under the house, settling sand cushion - with a minimum thickness of 15-20 cm;it should be shed water and well tamped.At the bottom of the first portion of the foundation is poured concrete solution - a thickness of no more than 10-20 cm. In the primary solution fits reinforced mesh, and the top is poured concrete solution to the surface of the soil.
If the tape base should protrude above the ground, it is necessary in advance to build the formwork made of wooden planks.Concrete solution should be poured into the formwork.Wooden boards formwork can be removed only after drying concrete solution.
