The FOUNDATION

The construction of any building begins with the Foundation (Foundation house). Building the Foundation should be approached very seriously. Properly executed, the Foundation will depend on the fate of Your home. What to consider when choosing a Foundation: first, what material the house will be built; secondly, the nature of the soil; third, the level of underground and ground water; fourthly, the presence of bias, etc. In this article we are talking about the choice of the Foundation under the wooden house. Wooden house, even frame, has a huge horizontal strength (try to break the beams in half and try to break a brick in half or foam block). The above strength allows you to put in a wooden house light-weight and therefore more expensive foundations.

So, what foundations to put in wooden house:

  • The most reliable low-depth tape monolithic reinforced Foundation. This type of Foundation is suitable for all wooden houses with solid lumber or timber walls and wood-frame houses. This type of Foundation can be applied to virtually all types of soils except peat. The total height of the Foundation (surface and ground) should be at least 0.7 m. Most homes are built on a strip Foundation. Strip Foundation is divided into two types. Monolithic strip Foundation is very strong, and it can be used in the construction of buildings of any type. Built the whole Foundation of reinforced concrete, from which with formwork tape is created of the Foundation, or continuous footing. According to the structure and strength strip Foundation of small blocks is a little different from a monolithic strip Foundation. The construction of the Foundation of small blocks are used, for example, light blocks Fibo, of which is pre-filled with concrete sole is laid masonry strip Foundation.
  • Slab Foundation or a monolithic slab poured over the entire area of the future building. It creates one large plate or grille that covers the Foundation of the house. The Foundation is made of reinforced concrete, but at the same time, can be created from a securely fastened transverse beams. Typically, the slab Foundation is built on a moderately heavy soil in the construction of private houses. It is best suited for soil that requires rigidity and strength, for example, soil with layers of clay-earth clay, and in areas with a high groundwater table. The construction of a slab Foundation requires a high material consumption, because it includes both metal and concrete. Not suitable for very large buildings with a simple form. The stove can be used as a floor, for example, garage or bath – this way you solve several problems at once.
  • Capital strip foundations with a ground floor. This Foundation can be used under any home. It is the most expensive and complex. At the same time, it allows you to take away from the main house in the ground floor boiler room, main bathroom, build a garage or sauna. The scheme of installation of such a Foundation is as follows: first to the sand cushion is poured monolithic reinforced slab, then the height of 1.3-1.5 m, monolithic reinforced poured Foundation walls, installed a brick plinth (with window openings) and covered with slabs. When building such a Foundation is especially important two points: the freezing depth and groundwater level. How to run this Foundation? If the groundwater level is below the freezing point, then everything is clear and simple, and if the above? There is a lovely, and most interesting, cost effective and are low-depth basement floors and the Foundation is not frozen, just produce embankment of the basement is excavated from the pit soil. This method has another plus – you do not fear that heavy rainfall will soak the walls of the ground floor because these walls begin above the old (main) level of the earth, though in a very neglected basement waterproofing is not necessary.

The choice of type of Foundation.

The type of Foundation selected, based on the character designs at home, design loads on the Foundation, the quality of soil, the sensitivity of home designs to uneven movement of the elements of the Foundation, exposure to freezing materials used.

The minimum thickness of the Foundation walls (and consequently the bearing area on the soil) depends on the weight of the house and the nature of the soil. The minimum depth of the Foundation depends on the proximity to groundwater, the thickness of the upper (soft soil). The minimum height of the Foundation depends on the total (minimum allowable) altitude tape, the thickness of snow cover (typical for the area), slope, presence of subfield and simply from Your desire.

If soil heaving or ground water lie high, and the building is expected big and heavy, you should prefer the strip Foundation. He is also the only possible solution for buildings with a basement, as the strip Foundation is better able to resist frost and can be build below the frost. The construction of the Foundation above the level of freezing, it must be carefully warmed. If the area with high groundwater table, then you need to consider the risk of basement flooding. Hence, such high demands on the quality of concrete. On the outside it is necessary to lay additional waterproofing.

Slab foundations are being built the fastest. If slab Foundation rigid enough, in the winter the house can rise a few inches. To avoid this, the Foundation should be well insulated. After removal of the soil is necessary to create a sub-base plate from small and have material such as gravel. In winter the upper layer of soil freezes the water. Freezing within the cracks increases and destroys the structure. It is therefore extremely important good insulation is. You need to ensure that you use special slab insulation, which absorbs significantly less water than, for example, insulation for floors EPS. It is also very important to build on the edge of the Foundation drainage. It needs to be below the "soles" of the Foundation.

The cost base is around 12-15% of the cost of the building. The amount will increase significantly if you order the Foundation along with pouring of the floor heating system "warm floor". The choice of type of Foundation and its device - a very important event. Contact the specialists!!!

Waterproofing of the Foundation.

The most important component of any Foundation is its waterproofing. The waterproofing of the Foundation has different purposes and is divided mainly into horizontal and vertical.

1. Waterproof as much hydroscopic gasket between the Foundation and wooden elements bottom trim of the house.

The most affordable ways of its devices:

  • laying on top of the basement a couple of layers of roofing material.
  • sticker (by means of bitumen mastic) on top of the basement a couple of layers of roofing material.
  • sticker on top of the Foundation waterproofing.
  • laying on top of a Foundation of a thin layer of fine gravel impregnated with bitumen mastic.

2. As waterproofing floors basement.

The most affordable ways of its devices

  •  sticker (by means of bitumen mastic) on top of the floor slabs of the basement a couple of layers of roofing material.
  • sticker on top of the floor slabs of basement waterproofing.

3. How to waterproofing basement floor before laying hardwood or tile floor.

The most affordable ways of its devices:

  • laying on top of the basement a couple of layers of roofing material.
  • sticker (by means of bitumen mastic) on top of the Foundation base plate of the Foundation a couple of layers of roofing material.
  • sticker on top of the Foundation slab Foundation Foundation waterproofing.

4. Vertical waterproofing to protect the Foundation walls from groundwater.

The most affordable ways of its devices:

  • If the groundwater level exceeds the depth of the Foundation, it is necessary to apply a waterproof laminated of rolled materials. In some cases, it is recommended to pour the Foundation layer of gravel, impregnated with bitumen.
  • It should be noted that the above-described approach to the waterproofing of the Foundation of the traditional and somewhat outdated. Lately, the technology of penetrating waterproofing, which is based on the ability of its own to fill all the voids to form in their crystals. But the cost of waterproofing the basement is pretty high! Basement waterproofing is quite important and necessary event.

When the device heating system in a wooden house you can use:

  • 1. Autonomous automatic (oil) heaters, both conventional and with the fans. To do this, professionals need to calculate the power of each heater, the number and specify the location of each of them. In the locations of the heating devices must be electric. outlet or special. connectors. Heaters for beauty, you can close the decorative wooden lattices.
  • 2.Water heating. The number, capacity and location of radiators is calculated by experts. Radiators, for beauty, you can close the decorative wooden lattices. Uses various types of boilers: gas, electricity, solid and liquid fuel. Use a variety of heating tube: iron, galvanized iron, copper, plastic, plastic.

In a wooden house is not recommended to hide the heating pipes in walls, ceilings and floors because in the event of a spill, the following problems occur:

  •  You may not immediately notice the leak.
  • Difficult to determine the exact place of leakage and, accordingly, it is difficult to quickly localize.
  • Gets wet and compresses, losing its thermal conductivity properties, insulation.
  • Rotting wood walls, ceilings and floors.
  • And, most worryingly, in order to fix a hidden pipeline, it is necessary to disassemble the flooring, the boarding of the ceiling or lining the walls, and You have all this new and beautiful!

Copper (carefully carried out) the pipes look very good, so they can not close. If the heating pipes look bad or highly salient, they can be closed easily removable wooden boxes.

Putting communications in a wooden house or a bath

Because the wooden house does not require the tabulation of deep-seated Foundation and, as a rule, is placed on the low-depth foundations, the pipes of water supply and the withdrawal of sewer pipes requires no special bookmark in the Foundation. Tubes just are summarized under the existing Foundation to the required depth. If a wooden house you want ground floor or basement when you install these structures, you need to immediately calculate where you need to put a special tab to enter water pipes and sewers.
