Building concrete house

Dreamed of building a comfortable country house for the whole family, but do not let finances? Do not hurry to part with a dream. Build a foundation and a box without spending a fortune, now you can own, using the technology of the individual building. We will understand the intricacies and details of this “popular method” – “Individual construction technology” method (ICT)

The technology is the possibility of low-cost and environmentally friendly self build box house: the foundation and the walls on any grounds, including heaving and non-cohesive (except silt). All work can be performed independently, ie without the involvement of workers and construction equipment, using special equipment: drill and formwork.

Construction of foundations for this technology involves installation of pile-tape (pile-rostverkovogo) grounds. Designed specifically for the technology foundation to manually drill to drill in a ground depression (3 m) under the future pile. Its design provides for a plow, by means of which operate in the borehole bottom extension (600 mm) to form the heel support post foundation.

Before the foundation of the device calculates the required depth of the piles, their width, pitch and location under the internal load-bearing walls and houses, as well as the height and width of the grillage. Construction experience shows that to ensure the necessary strength enough step pillars 1.5-2 m below the external and 1.2-1.5 m below the interior walls and pile cap height of 200-600 mm. More accurate parameters should identify experts architectural office based story structure, soil type, wall construction material and other individual criteria.

The bearing capacity of a pile depends on the diameter of the sole and the soil type. For example, one column with 400 mm extension, set in loam, capable of withstanding a load of 7.5 tonnes.

Not to get piles ruptured  from frost heave and ground motionst (ie, separation of the main pillars of the heel), metal bar reinforcement IS HIGHLY NEEDED !.

For this purpose, the rebar diameter of 10-12 mm, a bent-shaped hole U. In the two brackets mounted perpendicular to each other (cross-wise) so that their upper parts project from the base of the column to the grillage height that will tightly bind its foundation with reinforcement. Apart from any use permitted rods steel lengthy material: squares, iron strips, folded net. It is important that the metal was clean, as rust, dirt or paint will prevent tight adhesion with the concrete.


After completing reinforcement wells, start pouring concrete. From the quality of the solution depends on the reliability and durability of the foundation and structure of the whole. Here you can use a lot of options for concrete composition. Take one of these: cement grade 400 – part 1; water – about 0.7 parts; building sand river – 2 parts; gravel or macadam – 2 parts. Since ICT – inexpensive construction technology, it is usually the owners in order to save themselves prepare concrete solution, but if resources permit, it is better to order ready-mix at the building site – this will significantly shorten the construction of the foundation.

Concrete in the hole lay gradually layers in the 150-200 mm, sealing each by bayoneting, i.e ramming made using special spit or thin rod. After filling the hole expansion in a cylindrical part mounted “shirt” – a tube of rolled roofing material and equal to the width of the support pillars – and is filled with a solution. This allows you to create a smooth surface of the pile, waterproofed it and prevent leakage of scum in the ground. “Shirt” let out at 150-200 mm for forming the formwork ground part of the pile.

Building a basement

Using formwork,  you can build and basement walls. To do this, departing from the piles of not less than 1 m, produce and perform excavation masonry walling module  is similar to the external masonry partitions.
The walls of the basement in a heaving soils will experience strong buoyancy effect, so every fourth well honeycombed walls lay the rebar diameter of 12 mm (four rods) and poured concrete, forming a powerful vertical reinforced concrete beams. Opposite walls of the basement top tightly bind floor slab, and bottom – a monolithic screed.
After hardening of the concrete pillars supporting all necessarily waterproofing – coated with bitumen mastic, and top veiled glassine or any bitumen rolled material.


For a uniform load on the foundation pile grillage combined. First house on the perimeter between the supporting pillars flush them perform podsypku sand, then construct her shuttering of wooden planks height of 300-600 mm and a width equal to the thickness of the walls of the future, taking into account insulation and facade decoration. Bottom waterproofing glassine or roofing material to avoid seepage of concrete jelly in the sand. Then stack of reinforcement bars (10-14 mm), connecting them with the reinforcement piles. This will prevent the horizontal shift of the foundation. After the formwork serves first batch of concrete and his bayonet. On grouted stack top layer of reinforcement and the mixture is poured to the calculated level. In the volume of concrete grillage can lay brick and concrete battle, as the requirements for frost to be met by this design, significantly lower than that of the foundation pillars that are moist.





After solidification of the grillage produce stripping removed sand underpowdering and proceed to build the walls of the blocks, forming them in place using prefabricated modules TISE. They are available in three versions: TISE-1 is used for laying of internal partition thickness of 190 mm, TISE-2 is used for the construction of both internal and external walls are 250mm thick TISE-3 – only for load-bearing structures in the 380 mm. Each module consists of a form of two removable blockout, pins and other additional equipment.

To create the blocks used solution sand, cement M400 and a small amount of water, in a ratio of 3: 1: 0.5. This semi-dry mixture allows for stripping immediately after molding “bricks”. Module TISE set at the beginning of the series and in two steps lay in his prepared solution with layer seal rammer until laitance, then remove the formwork and placing it next to the finished block form New. Wall build in layers. Each subsequent row is laid up on the previous one and without underlying solution.

Important quality modules TISE – they dampen seismic and vibrotolchki. Blocks TISE indispensable in the construction of buildings along roads, flyovers and railways, as it does not transmit vibration loads.
When forming units prepare holes for ventilation, electrical wiring or slots under the beam. For this purpose, the module is inserted into special inserts, which are removed together with the stripping. After placing a number of 5-10 “bricks” seams between them overwritten concrete and sand mix solution. Every four or five rows of masonry reinforcement performed using welded mesh or rods with a diameter of 5-6 mm.

The walls are lined up on technology ICT, insulated foam boards, polystyrene or mineral wool or fill internal voids shaped blocks of insulating materials (foam chippings, concrete block, etc.).

To avoid thermal bridges sometimes produce masonry walls in two rows, using formwork ICT-1. The space between the baffles also fill insulation.


As you can see, to build the foundation and walls on ICT own, without the involvement of workers and special equipment is quite possible. This will require only the time (at least two to three months) and strength. But is economically justified such construction? If we count only the cost of building materials (concrete mix, rebar, formwork boards,ICT equipment ) necessary for the foundation and walls of the two-storey house 6 × 8 m, then they will be about 200-250 thousand. Rub. The price of one unit ICT – $ 2., In principle, comparable to the cost of foam blocks ($ 2-4.), So in terms of man-hours to build a more profitable building envelope of cellular concrete. Another question – the reliability of the walls of these porous materials. Apparatus foundation for this technology would cost significantly smaller amount compared to the base of the finished screw piles, so in this case ICT itself justifies.

Happy building !
