Everything is possible: the real story of dismantling and alteration of UWB

In the article: the consequences of the mistakes in the construction of the Swedish warmed plates, and how to build UWB according to the rules

In the first part of the epic «Slipped UWB: causes and treatment» we talked in detail about emergency warmed with Swedish stove. Cause? Bungler violated all the rules in the construction of UWB. As a result, the user FORUMHOUSE a_ivanov I hit the big money. Want to know what ended the story, and how much cost to build a new stove? See below for details.

How to break the Swedish sagging warmed plate and how much it costs

Immediately show on what end of the first article.

Customer UWB, which slipped from the jamb-builders hacks

I decided to break the UWB so as to best preserve for recycling extruded polystyrene. At work hired three workers. I gave them two breakers. Work hard. I think they will cope more quickly, but the time it took longer than expected.

The big request! Show the cushion opening process under the slab. I'd like to understand what shalturili builders.

a_ivanov

Be sure to show you! In the meantime, check the condition of pipes were insulated floor. When pouring UWB rubble pushing wall.

The reason cant - pouring front plate, builders-bunglers not filled in the coolant tubes or crimped floor heating system under pressure.

a_ivanov

Look at Epps, who got work. Geometry saved, but there is a hole on a jackhammer. Extrusion cookers from a central part of the plate better preserved. I think to put them on the blind area. The bottom layer Epps was able to extract practically free from damage. I use it again when pouring a new slab.

Interestingly, and how much you cost "mercenaries" and tool rentals?

a_ivanov

It worked 2-3. On the plate dismantling it took two weeks. I planned that the workers will manage the last 7 days, but hindered floor heating pipes and fittings. They kept the concrete. We had to cut them. On money: for all I paid 50 thousand. rub. Epps preserved 100 thousand. rub. More dug sewer pipes. Fight concrete is used for the formation of the correct "cushion" for UWB.

Dismantling of concrete is finished.

On the site launched a tractor to remove kosyachny "cushion".

a_ivanov

Dig started from a corner, which dipped by 15 cm. Look at the picture below. Excavator bucket gets full of topsoil. More found in the "cushion" plastic bottle. That's how I made the base for UWB.

In the video - demontazh kosyachny "cushion" under the warmed Swedish stove.

a_ivanov

And in the corner, which is not dipped, the mold was removed completely. Figured black earth remained approximately at half the plate. Here you have One of the reasons for the foundation subsidence.

Further a_ivanov started the construction of a new Swedish warmed plates. To this end, he hired a trusted expert with FORUMHOUSE.

Steps for preparing a reliable base plate warmed Swedish

a_ivanov

I removed all the black earth. Foundation pit dug up clay. This time, I'll check all the stages! The bottom of the pit first hammered gravel remaining on the old foundation. Then spread a geotextile and sand poured out. Sand and water shedding layers ramming vibratory plates weighing 300 kg. Geotextile bought width of 6 m and a density of 300 g / m², instead of a width of 2 m and a density of 200 g / m², as the first time. With a width of 6 m there is less overlaps. So safer and cheaper. Immediately made drainage. During. During the night it began to rain, but the pit was dry.

Hard-packed sand.

al185

A geotextile overlaps what? 50 cm if no cross-linking?

a_ivanov

Yes, overlaps of 50 cm. The photo already upper layer of gravel in the sand.

a_ivanov

​Compare the sand from the first "cushion" and of the new. As they say - two big differences.

The second school of builders of the first UWB - for the use of the "cushion" of fine silty sand.

​He looked at the photo, where geotextiles. I do not understand, you put a layer of sand on the second layer of geotextile? What for? And a layer of gravel plan?

a_ivanov

That's right. After another sand layer a geotextile and gravel fractions 20-40 15 cm thick. This time the pillow will be brought to the level, which was previously the highest point of the first plate.

Groundworkturf

I constantly repeat, do not need a geotextile layer between the sand and gravel! Remember, geotextiles need for the separation of soil and inert materials to avoid their interpenetration. From a second layer of geotextile, with a small layer of sand, up to 50 cm, and only harm no benefit. Now, as I understand, too late to alter. Nothing terrible, but the base of the strength of these activities you will not have strengthened and weakened.

The builder of the new UWB

I agree with Groundworkturf on the geotextile. Ideally, it is necessary to make a "cushion" for UWB entirely of rubble, but it did not fit in the construction of the planned budget. At the facility a_ivanov we did:

• We chose the bulk of the excavation soil with plant remnants layer.
• Spread a geotextile.
• Poured sand bed of sand of average grain size, 0.7 m thick to the existing ground level.
• Put a second layer of geotextile.
• Made crushed rock pillow 15 cm thick rasklintsovkoy classifying and alignment for laying Epps.

a_ivanov

Crushed guys scattered by hand, even though I was willing to pay for a tractor. 40 cubic meters of gravel was laid and rammed for 2 days.

User Forumhouse, from which, in fact, began the history of UWB RF

I have always said that to "cushion" under the UWB should gocrushed stone, concrete or Skalník fight. Sand it is only necessary to equate the top of the base under the insulation.

The cost of work and materials on the base of the unit is insulated by the Swedish stove - 230 thousand. rub.

Installation of the formwork, Epps, valves, floor heating and pouring concrete UWB

a_ivanov

Builders assembled shuttering of boards section 4x10 cm. On the left is a 1 cu.

a_ivanov

Then they laid sewer pipes and made entry into the water and electric cable.

Further, all the work was divided into stages:

• They laid a layer of insulation that is removed from the broken foundation.

• Drank on Epps "tooth".

• Assembled pipe for hot and cold water supply 16 mm diameter.

• Made wiring sewage in the upper layer of Epps and installed two ladder: for the shower and the boiler room.

• Laid pipe warm floor of the reinforcement cage using three types of "chairs" of varying heights.

Pipe diameter - 17 mm. Step placement - 15 cm. Along the edges of tube plate paved separate loop with step 10 cm.

• The branches are connected to the underfloor heating manifold and the compression.

a_ivanov

For laying electrical wire 3x2.5 mm, builders used a hidden mounting box. They are mounted in concrete at a height of about 2 cm from the floor surface. Subsequently, it suffices to find a box of pre-drawn map, drill a few holes and remove the cable.

The final stage - UWB poured and smoothed concrete surface under the floor finish "Helicopter".

a_ivanov

 On the plate there elevation within + - 5 mm. This is normal?

Groundworkturf

By SNP tolerance of 10 mm in the entire length. You just perfect.

conclusions

The dramatic story a_ivanov with sagging UWB ended happy ending. In order not to get the builders in the money, do not waste your nerves and do not run around the courts futile, remember:

• Before you build something, learn all the steps and the right technology.
• Watch the video, which shows the correct installation, describes the nuances of technology. If you do not understand something, ask to FORUMHOUSE.
• Do not believe the "tales" builders and foreman, "we always build and yet it is not broke."
• Check yourself every stage of construction.
• Money for the work performed on the Render steps rather than all at once.
• Participate, or purchase all the building materials themselves. So you will not heat in the postscript to the price.

And most importantly - if a team is clearly kosyachit, Foreman does not listen to reasonable arguments and dismisses your comments - expel bungler. So you will save the money and you do not have to grab his head and cry blue murder when prosyadet foundation, walls cracked and covered with mold.

Read the whole saga with emergency warmed Swedish plates can be in the subject line: UWB slipped plate after pouring. Help, what can I do?

We recommend the article:
