Proper warm cake otmostki

Many novice developers think that the main purpose of the blind area - is to protect the foundation from precipitation, and walk on it simpler and easier around the house. But, as experience shows forumhouse.ru users properly made and blind area with insulation, coupled with the drainage system can solve a much wider range of tasks - from reducing the forces of frost heaving, a devastating effect on the foundation to drain groundwater and protection ground floor.

Warming of the blind area around the house

That is why the blind area, as well as warmed ledgeIt can not be regarded otherwise than a complex system, but in order to make things right, should heed the advice of our members of the forum.

- The house I started to build about seven years ago, and the foundation extrusion occurred only in the last two years. The foundation of my band-columnar. Tape nezaglublonnaya 40h20 cm pillars 1.6m Why it happened, I now understand:. Otmostku and drainage time did not.

A user with the nickname al185 In this case, the Council insulate basement and blind area. It is also important to make literate surface drainage.

In order to prevent extrusion of the foundation in the future, you first need to:

• Divert water;
• Insulate foundation.

Felo(User FORUMHOUSE):

- This summer I plan to blind area around the house with insulation, and for reducing the groundwater level want to dilute the drainage pipe to the ditch.

Chitatyte article on how to approachto the choice of foundation.

To reduce the groundwater level was impossible to leave two broken pipe, connecting with each other roadside ditches, and our party has decided to replace them.

Water safely go into the forest and the water level in the area fell by 20 cm.

It was later made warm blind area, foundation drainage and storm sewer. And as shown by the season, all of the above measures helped prevent further bulging of the foundation.

Apparatus insulated otmostki

Warmed otmostka consists of stacked around the underground part of the foundation horizontally or at a slight angle or sheets of extruded polystyrene foam. insulation sheets stacked to a depth of 30-40 cm from the ground level at a slight angle from the direction of the foundation, which provides water flow. Due to the insulation around the foundation soil does not freeze, and thus greatly reduced the power of frost heaving.

With insulation to a blind area showed all their positive qualities to the fullest extent of its you need to properly mount and for the construction of this process should be divided into successive stages.

- The perimeter of the house, I dug up on a bayonet spade 1.3 m from the wall. In only the fourth wall removed topsoil. It turned about 20 cubic meters of earth.

The second step was to first fill layer CBC 10 cm thick, smooth it, compacted and put it Epps thickness of 10 cm.

Valentin Penza(User FORUMHOUSE):

- I peretaskat in the blind area 14 ASG cubes. In order to ensure a snug fit sheets Epps to the ground, I leveled on beacons backfill, tamp down, bar, and then fell asleep with wet sand (watered bunch of hose) and leveled regulation. The thin layer of sand on top ASG obtain a smooth surface with a slope from the wall 3 cm per meter.

Valentin Penza(User FORUMHOUSE):

- After that, I went for a month from the construction site, and when he arrived, the surface was still feels like concrete. Only a thin upper layer of sand partially washed away rain. But foam still lay perfectly. Without any breaks and gaps.

Epps our forumchanin was putting the long side of the wall, ie, 1.2 m.

Valentin Penza(User FORUMHOUSE):

- Sheets of foam, I hid the thickest polyethylene, which just happens to sell.

Then forumchanin began insulate part of the foundation of the foam to the level where the concrete will come to an end. And in order to separate the concrete from the wall of the blind area, Valentin Penza, Epps precut 5 cm thick, with a special glue the sheets glued to the wall.

Valentin Penza (User FORUMHOUSE):

- The result was like one continuous piece of formwork. And I wrapped polyethylene at these bars.

Thereafter, the film was expanded over another layer CBC approximately 12 cm. Material beacons leveled and stamped metal pipe vibratory plates. Then came the turn of the formwork.

Valentin Penza(User FORUMHOUSE):

- For perfectly smooth rammed ASG at a distance of 1.1 m from the wall, I put it on the edge of the board 10 of the. Secure it so: outside rammed CBC tapes into the ground hammered pegs and short dosochki and with the help of screws put together with boards of formwork.

A total of 6 cubic meters of concrete was flooded, and the casting process took 1.5 hours. After smoothing the surface Valentin Penza closed otmostku film and three days poured concrete until it has hardened. The result of this work you can see in the photo below.

Valentin Penza(User FORUMHOUSE):

- otmostki out flat and smooth. And most importantly, high - it managed to raise the surface in some places even 35 cm and now the house is worth, as it were on a hill, and all the water drains away. It was tested in the shower time.

But there is another view of a device blind area. Vladimir Tallinn recommends that no concrete blind area, in order to avoid cracking of the structure, but just warm and top with paving stones. Here's why: the main task warmed blind area - is, nevertheless, insulation; heat preservation at around the foundation zone.

See our theme "blind area, she track from the rubble".

A Anatoly, Moscow(User FORUMHOUSE):

- I have a thick layer of insulation on the blind area of ​​100 mm, and on the foundation of just 50 mm. Then everyone decides for himself and thinks, but there are certain criteria that one can not stick to. This heat of the earth, which should be maintained at the largest possible area around the house, and who then will not let the cold penetrate to the foundation depth.

Also, our user has decided on the perimeter of the blind area to mount the drain pipe 110 mm in diameter is wrapped on a ¾ waterproofing membrane by the use of which all perched and precipitation are retracted from the foundation.

Anatoly L(User FORUMHOUSE):

- In my case, the main task was to collect perched with blind area, and part of the film abroad. Pipe though wrapped membrane, but lies at a depth of about 30 cm, and why horse collects water and for its boundary. Besides the use of films and does not give silted geotextile filter tube.

When the drainage device is very important to maintain the desired bias in the average is 1 cm per linear meter of drain tube, but also there is no well-defined values.

Anatoly L(User FORUMHOUSE):

-Uklon I withstood approximately 2-3 cm per n / m, and the pipes converge at a point on the drain. Before the drainage pipe laid, I shed the surface of the future blind area with a hose. Making sure that water goes where I want, I put the tube, wrapped it in a geotextile, waterproofing membrane wrapped, covered with sand and buried.

The use of sand in such a cake can greatly minimize the blind area, because it is in principle only for the site leveling for laying insulation. And it is better to use a mixture of sand and loam - then he will tamp and water-resistant to a certain extent.

As a result of the above activities is moving away from the base boundary of freezing. Warming reduces the blind area, and even eliminates the progress of soil, tile, concrete blind area in the basement.

Anatoly L(User FORUMHOUSE):

- After insulate the blind area, I measured the temperature at the street - 30- 35C for a week or two in an unheated house without blind area and the blind area. Winter in an unheated house was much warmer in the basement and on the floor - an average of six degrees. Is not this proof performance insulated blind area!
