FAQ
How much does a one plant scale cost?
This is an easy question, but it’s very hard to answer it. The price depends on many factors: the shape of the stairs, anchorage (self-supporting, anchorage into the walls etc.) the distance from Brno etc. We recommend filling in the part – Price calculation. It’s the pre-estimate of the price in accordance with the dates you fill in.

Will you transport the scale or will you do it on the construction site?
We are capable of both solutions. The prefabricated spiral stairs (U-shaped) are transported onto the construction site including the installation. For individually designed stairs we offer the realisation on the construction site (measurement, boarding, armature, concreting, elimination of the boarding).

How long does the realisation take?
For prefabricated units that we have in our proposal, we have already prepared mould. We are capable of delivering the order 14 days after the resource has been paid. For a new shape, we have to do a new mould so it’s necessary to solve the situation individually. The monolithic variant (construction directly on the construction site) takes between 3 – 10 working days. Everything depends on how the project is complicated.

Where can you use the concrete stairs?
Here are some of places where we already have constructed our stairs:
- Monolithic and mounted constructions
- New-buildings, reconstructions of houses
- Exterior as well as interior projects
- Main entrance stairs for buildings
- Family houses including wooden buildings
- Apartment buildings
- Commercial and company buildings
- Administrative buildings
- Banks, offices, schools
- Historical buildings
- Church towers
- Garden and swimming pool stairs
- Fire escape stairs
- And other places…


Tell me, why should I order a concrete floor? I think I had enough of it in my previous apartment house.
We think the prerogatives are:
- Universal material for interiors and exteriors
- Modern material – the fair-faced concrete
- High load with subtle shape
- Fire-resistant structure
- Minimal rumour – no transition of the vibrations into the walls
- Low price
- Use already during the fabric part of the project. From this results the safety of workers during the construction.
- Hidden saves thanks to better communication between workers and material
- Possibility of self-supporting construction or anchorage into the enclosure wall.
- The variety of shapes (direct boards, spirals, spindles, “toothed” construction etc.)
- Individual solution in accordance to the preferences of client.
- Elegant details of the stairs such as the handrail without columns.
- Possibility of material combinations for the steps and railing (wood, stone, steel, glass, terazzo, PVC and others)
- An easy reparation of damages on the steps
- Possibility of superficies modifications to better suite to the interior

The minuses. Can you resolve them?
The wet construction – during the fabric construction it does not make the difference and for already constructed interiors we use special materials that absorb the water.
The long drying time – has already been cleared in the previous explanation
The robust shape – a good structural designer can make a subtle construction.

When can we use the stairs?
The prefabricated stairs can be used immediately after the installation. The monolithic stairs can be used one day after they were installed with small load (they need to be treated with water). Two days after the installation you can use the stairs without any limitations.


When do you eliminate the boarding?
This depends on the construction type as well as on the anchorage and weather. Generally we eliminate the boarding after 7-14 days.


What do we need to prepare before your arrival?
For both types of construction it’s necessary to have the supporting wall, ceiling, and insulated floor.

Do you offer all in one stairs like the ones that are showed on your website?
Unfortunately we don’t. We provide only the concrete constructions as a semi-finished product with or without superficial modifications. The final aspect of the stair is a result of longer work, made by other suppliers. We give to our clients as well the list of our collaborators. The client has so the opportunity to expand his selection and decide peacefully what he wants.

What’s the type of the concrete used for the constructions?
For monolithic stairs we use the concrete of the B-20 class, imported from the nearest concreting plant all over the Czech Republic. The prefabricated unit is made from the type B-30.

Will you do me a stair even in As?
Yes, we will.

Is it possible to do the stairs even in winter?
Of course, it is. For these cases we have winter precautions (boarding against strong wind) and the B-30 concrete includes plasticizers against the freezing. During the drying time we cover the construction with isolation.

What do you need to know to make an offer?
For doing an offer we would please you to send us the following information via e-mail, fax or post.
- Ground-plans of the plants that should be connected
- Stair cross section (the height of the construction)
- The locality of construction (the distance from Brno)

How long do you need to make an offer?
If do not need an alternative solution, we are able to do the proposal in 48 hours. If you want an alternative solution, then we need from 3 to 4 days.

I want to have the concrete stairs in an attic placing with a wooden ceiling. Is it possible?
We have already resolved this problem once. It’s necessary to take a closer look onto the whole attic. We can say, that after some modifications it’s also possible to use the concrete stairs even there.



Can you produce even other shapes of prefabricated units?
Yes we can. We are capable of producing other shapes. Decisive is the amount of order. Acceptable prices for a new mould stair begin from 8 pieces onwards.

When can you deliver the prefabricated stairs?
A stairs from a existing mould can be deliver in approximately 14 days after the resource has been paid. With a new mould it takes approximately one month.

The width of the scale results too small. How can you resolve it?
We resolve it in two ways. One way is to have less scales, the other one is to cut the riser. You can find a better explanation in the section Project.
