Insulated otmostka own hands: incremental algorithm

Why is it necessary to insulate the blind area around the house? Insulated blind area around the house with his own hands. insulation scheme

Does it make sense to insulate the blind area, if the house is not heated in the winter? Does it save us from the forces of frost heaving, and from the destruction of the foundation? Member of our portal with Papahomi nickname is now convinced that warming of the blind area, and the cap is always required when it comes to melkozaglublennom foundation on heaving soils. And it is - irrespective of the basement or cellar.

This conviction is dictated by our user experience, the son of the difficult and rather costly mistakes: on We went foundation cracks, and he had to redo blind area, which was first made without insulation.

On the example of this sad story we tell in detail how to make a blind area MZLF insulation and a cap.

1 - soil; 2 - geotextile, 2 m; 3 - Sand with a bias; 4 - 1/2 ASB tube. cement, diameter 100 mm; 5 - extruded PPS, 80 mm (50 + 2 layer 30 with overlap seams); 6 - a metal mesh, welded, with wire thickness of 3 mm; 7 - shaped diaphragm with improved drainage capacity, size of 1.5 m, 20 m; 8 - crushed stone; 9 - foamglass 400h475h60 mm 2 layer; 10 - socket.

Cake insulated blind area: the solution proposed by forum member with the nickname Vpenkov. But there is still livnovka in the blind area around the perimeter, if irrelevant, paragraphs 4 and 6 to remove.

Pie soft otmostki

Our user with the nickname Papahomi square log house built on MZLF 10x12 m: 40x80 cm on tape tridtsatisantimetrovoy sand cushion recessed from 10-40 cm (due to tapering).

Non-insulated soft blind area for the drainage of water away from the foundation was made a year later.

Papahomi

He stopped on a soft blind area, as a more maintainable, and stocks with a concrete surfaced among the people at that time a lot.

otmostki design was made from nonwoven geotextile density 200, geomembranes with the pressure profile, fractions 20-40 gravel and coarse sand.

 In the first stage of the foundation perimeter removed soil to a depth of 20 cm. Since this blind area should still work path, in places with a "heavy traffic", its width is 140 cm, and the rest of -120 cm.

Papahomi

Along the perimeter dug trough arranged in the groove depth of bayonet spade and asked her uklonchik towards natural lowering the ground level.

Compacted soil, sand made the slope away from the house to the groove. Sand shed and stamped. Usually at this point the cake soft otmostki lay geotextile, but Papahomi missed it: his tight mainland soil, and over the years, "nothing settled." You could even do without the sand, simply stall the ground sloped.

Papahomi

Sand laid on the membrane and the pressure profile attached to the foundation. To do this all over the basement through every 30-40 cm to make a hole and fixed profile dowel-nail. On one side of the membrane with a 15 cm overlap laid on the foundation, and on the other - to the drainage groove.

Groove lay a geotextile and covered with gravel.

The membrane is filled sand (shedding and tamping).

Sand laid on one layer of geotextile, and on top of the rubble.

In the end it turned here is the foundation on which planned paving.

Otmostka served for only two years, and that on both sides of the foundation went fine vertical cracks.

Fortunately, before laying the pavers in the hands of the blind area and we have not reached, but still, rework and warming of the blind area, together with a cap Epps took a lot of time and money.

How to Make Insulated otmostku

In work on the circuit insulation Papahomi I relied on the work of the FSUE "SRC Building" "The use of insulation boards of polystyrene foam extrusion apparatus and in the design of foundations on heaving melkozaglubennyh ground. "

Papahomi

I have done so: in the perimeter of the porch and terraces continuous warming of the earth in a single layer of 50 mm, insulation tape foundation only from home. On the outer corners - 2 layers at a distance of 1.2 m from the corner to the two sides (100 mm).

When choosing our Epps guided by a single criterion: the manufacturer should be well-known and large, it gives confidence in the quality.

Before gluing on the plinth Papahomi Epps hacksaw sanded on both sides. Samostroyschiki often neglected the operation, but that it provides good adhesion and insulation-foam adhesive. Clay is better not to save.

After gluing material fastened on fungi 120mm. Subsequently, the participants of this forum pointed handyman for error: it per square meter of the material took 6-7 dowels, and should be 10-12 pieces.

At first Papahomi Epps pasted cap. On the ground, he was packing material with a slight slope from the house and stuck to the Epps on the plinth. The sheets were fastened on the ground butt the sheets on a base, under the end they did not plant.

On insulation clamp strip fastened to the cap membrane.

Papahomi

The bar is attached directly to the insulation dowel-nails. Pressed normally. Under the bar, you can leave a small allowance of the membrane, so that when filling it vomited out from under the bar.

The membrane pour a layer of sand, then - on top of geotextile and gravel.

How did sewerage

For the removal of water from the blind area along its perimeter master dug to lay an inclined groove and a strip of geotextile, so that one end protrudes slightly above the ground, and the other came on the slope under the blind area Epps about 30 cm. In the geotextile in the form of troughs he laid banner strip so that the membrane overlaps the blind area.

Split hairs with the banner had to because of the wide blind area. If it was narrow, it was possible to simply omit the membrane into the groove and make a trough for water from it.

Papahomi

I is the length of the sheet otmostka Epps 1.2 m, so the width of 1.5 m membrane chute I lacked.

The trough of our party banner set livnevki pipe, poured protective layer of sand 5 cm, so that gravel does not rupture membrane on it - and the geotextile layer of gravel.

Papahomi

Water flows through the membrane, falls into a ditch, and it is given away from home.

Do I need a cake in this rubble?

The manual device for paving ground under rubble and there acts as a drainage layer.

All the water from the roof of the pipes will be removed in a ditch outside the area. As the audit showed gidrourovnya, for this is enough natural slope of the site to the ditch.

Papahomi

The pipes are laid with a gradient of 2-3 cm / n. m. to get to the depth of the ditch. Total removal has 2 branches in the ditch - the right and left roof slopes of individual routes.

Sewage is not necessary to use a red tube, as in the photo - it is flexible enough double layer: they are easy to cut with a knife by a simple, easy to install and, by the way, are joined with the standard red.

After warming the perimeter of our user base and plastered plaster primed to close the pores of the painting and glue mixture.

The next stage - the pavers. We chose the budget option, coloring to match the main color of the house.

Papahomi

Anticipating possible questions on the cake under the paving stones report: gravel 20-40, 5-20 rasklintsovka gravel and sand, geotextile, sand washed 4 cm, paving stones. Naturally, layered accurate tamping vibratory plates.

In the schemes, which guided our users, developing otmostki chart shows that the insulation must be carried out is carried out at the level of foundation base. In this case, the insulation got 15-20 centimeters above. Incomplete penetration will be offset by the width of insulating skirt, which is more than the recommended.

Papahomi

It was already difficult to dig deeper.

Do I need to insulate the blind area

The topic Papahomi expected about the dispute, whether the warming of the blind area to prevent frost heaving of soil, if the house is not heated in the winter: technology has come to us from Canada, Sweden, Finland, and in these countries the concept of "cottage" is not at all heated home round year.

Majority of votes agreed on the fact that, yes, it is necessary to insulate.

If you take my specific conditions (a low level of groundwater), the insulation will not give blind area rain fall and snowmelt waters under the foundation, thus significantly reducing the power of frost heaving ground.

Papahomi

Frost heave triggered by the simultaneous presence of a tape of two factors: water and freezing. Guaranteed removal of one of them to avoid frost heave at Funda.

Initially, it was from the foundation was made incomplete removal, and perched on the tape came to the clay formation. Eliminating the blind area and the freezing of insulation base, and improving sanitation, our users are certain that with the frost heaving under the foundation he does not meet any more. Fortunately, these cracks in the foundation are not critical to the wooden house - this is on the walls of the block would have already gone cracks.

Options insulation otmostki

Let's see a few more options for warm blind area of ​​our portal.

Druzhnyi I made warm otmostku back in 2013, and is still "no swelling there." The only thing: once he wakes up all otmostku peskosmesyu. Another point: the membrane is spread out to the entire width of two meters.

Here's a variation of the blind area of ​​our participant with the nickname ArtBern

ArtBern

The foundation - a plate, a plate Epps, 10 cm. Drainage at a distance of 120 cm, the depth of 50-80 cm. Warming cap - sanded Epps. The joint sheet Epps laid pipe insulation, leveled sand base for Epps blind area. Everywhere we maintain a bias. Sand rammer and by pouring, base under dry mixture. Corners conclusions livnevki outside the blind area.

Ddg26 Insulated soft made blind area for the bath.

Ddg26

It turned out that's so soft blind area for the bath and the sink at the same time. Styrofoam can and put nothing, but there's someone like.

conclusions

After the story of our users is convinced that:

• insulate the foundation must immediately when filling;
• warm blind area must be done immediately in the first year.

Papahomi

In my case, Fundam survived three winters and cracked. You do not want the experiment, immediately after casting.
