Before the disposal of insulant, because of the inequality of flooring concrete. We can determine the thickness of insulant and the estrichbeton thickness.
The engineer and the electrician chisels the walls and these pipes run on top of the flooring concrete, so it's worthy to prepare the protection beforehead the estrich concrete.
4,5 cm, but we can reduct it. We extract this in an other question in detail.
In case of one machine We can prepare daily 150 sqm handmade/mechanical smoothing. Of course this can be increased with every single day, since the first workday contains the preparations.
Like the all concrete the estrich concrete shrinks and expands too, tehrefore of this edge insulator we fix a foam stripe onto the wall, what is used for the case of the shrinkage and enlargement, and protects against the knocking sound. At underfloor heating rooms we relieve it with 1 cm edge insulator since the concrete's hot enlargement is bigger due to the heating. At rooms without heating we use half cm edge insulator, since the hot enlargement is smaller.
Till -5°C we are laying concrete since the concrete does not harden under this, but this can be possible even to - 15°C with the application of chemicals and hot tempering.
At 20°C in 2 days.
Between 20°C and 5°C in 3 days
Between 5°C and - 15°C in a week
It may digress, since everything depends on the thickness.
The cold casingunits in 1,5-2 weeks. The warm casing at least 28 days, recommended 1,5 months to wait, because awter that time the concrete won't not influence the casing.
28 days or more, depends on teh weather. Under 0°C we need to wait for one and a half months until the disposal of the warm casing.
We apply the thread strength concrete if the thickness of the insulation is thicker, than it's flooring concrete. The thickness of the concrete is starting from 3 cm and the be maximum 4 cm, since the splittings are hampered by the thread strengthening we recommend this in special cases.
Yes, of course. In the underfloor heating - and without underfloor heating rooms, we undertake revealing the cards. Of course the mending of the underfloor we do not undertake.
No, it's not necessary, since we work with a chemical that insures the moistness both for follow-up care, and the conrete too.
Yes, we can even decrease the drying time to 8 days. We suggest to use it at floor rooms, as the deadline hurries. Since the price of this chemical is higher rather think ahead!
We usually use it at places bigger than 35 sqm. In smaller rooms we place it near to the partition and a doorway occupy a position away. This falls into the direction of the doorway in all cases.
Distance: 150 meter
Height: 9. floor
Yes, of course. If the client claims the 0,8 construction, which is much stronger and more lasting - we smooth it with hand. If the client wants the 0,4 construction - we smooth it mechanically which is more inferior quality, but does not differ from the 0,8 construction in a price. We entrust the decision to the clien.
Yes, if the client guarantees that he would order the same quality substance, we constructors have suggested. Of course the pledge price decreases by the price of the substance.
Yes, on Saturdays. If it is urgent to start a work, and the surface of the concreted area can be finnished in a workday.
