When the house starts with UWB

Readers of our portal is well known to the statement "the fate of the home depends on the reliability of its warping." That is why the choice of the type of foundation should be approached thoughtfully and carefully weigh the "pros" and "cons." FORUMHOUSE experts talk about the strengths and weaknesses of UWB, and help to understand what the benefits and risks of receiving the developer, chose this type of foundation.

What is UWB

This type of base for the construction of the house is a monolithic foundation laying low. Its main difference from the usual plates that are installed in the UWB advance all the necessary communications, namely:

• water floor heating system;
• water supply and sewerage system;
• Power supply system.

UWB: Pros and Cons

At the mention of the word "foundation" of most developers is simple, concrete baseIt formed as a plate or a tape. But many people have heard about, and this type of foundation, where all the necessary communications conducted in advance, and the base itself is perfectly flat surface, already prepared for installation finished floor.

This approach can significantly reduce the time of construction of the building, and if the foundation is well insulated, it It performs the function of the storage tank, reducing heating costs and making your home comfortable and energy-efficient.

Such a foundation for the house called "Swedish stove with insulation." Opinions about the place of origin of the technology vary, but experts agree on one thing - compared to conventional, foundation UWB is more energy efficient and functional basis for the construction of a modern houses. Consider the pros and cons of UWB foundation.

advantages of UWB

In 2008 FORUMHOUSE Russia's first mention of the foundation has been fixed for the house UWB is ideally suited for karkasnika. In our latitudes, this technology was not yet known, but then quickly gained immense popularity.
Here are its main advantages:

• It can be installed on almost any type of soil;
• Quick construction time;
• A layer of insulation reduces the heat loss in the room;
• Less compared to conventional slab foundation, concrete consumption;
• The base already prepared for laying the finished floor;
• The Warming of the Swedish stove in advance the necessary integrated utilities.

cons UWB

But no matter how good the UWB foundation cons him too. These disadvantages could be arguments against such a decision of the foundation issues:

•  Increased demands on the materials used, technology, training of workers and the need for strict observance of the technology, which increases the cost of the work;
  
• Compared with the belt, the foundation type UWB has a lower height (an average of 300 to 400 mm);
  
•  On uneven terrain with a large height difference for a foundation of the house need to be leveled area, which also leads to an increase in the cost of operations;
  
•  When using insulated Swedish stove is impossible or significantly complicated by the construction of the basement, and its construction costs lead to an unjustified increase in the cost of the house;
  
•  Since all communications are conducted within the Swedish insulated panels, access to them to carry out repairs in an emergency difficult.

For any soil suitable UWB 

Alexander Zemskov (head BAUBILD Company):

For warmed Swedish plates virtually no restrictions on the type of ground on which it may reside. UWB worked well on complex soils with high ground water levels and low bearing capacity. This type of foundation is successfully used in cold regions where seasonal freezing soil leads to forces of frost heaving.

Due to the substitution of unstable soil under UWB pad of sand and gravel and "reinforcement" base geotextile You can achieve its placement on very difficult terrain, and the drainage system will lower the groundwater level in the spot building.

If the decision to use as the foundation for the house of UWB, it should be noted that the technological complexity of its manufacture is much superior to other kinds of plate bases.
Before starting the installation, you must:

• Create detailed project how your future house with all the necessary utilities, and foundation;
• Adhere strictly to technology and the construction sequence;
• Bookmark and maintenance of all communications should be implemented to within centimeters.

Insulated Swedish stove: how to reduce the cost of

Since the warmed Swedish stove can not be compared with conventional tape or slab foundation, You need to find out what benefits should get the developer, if he chooses this type of foundation for his house.

Mikhail Leontiev (head Schwedenplate company projects):

The developer gets the right all the necessary elements to it in the future: the foundation, subfloor and heating system with the necessary communications. You could say that thanks to the speed of erection of one month you will get a comprehensive system that can be connected to the heat source. And thanks to its heat capacity, UWB foundation provides additional benefits for heating heat pumps.

Alexander Zemskov:

On average, the foundation 100 m2 manufactured for 7 days. Concrete surface warmed Swedish plates requires no additional tie, and, thanks to grinding, it is ready for laying the finishing flooring. A comprehensive approach to construction reduces the final cost of installation.

Strip foundation with a set of communications, drainage, floor heating, laying water pipes, electrical cables carrying, installation sewerage and additional insulation can be realized not less than 30 days, and its final cost will be 20-30% higher than the UWB.

UWB for frame houses 

Insulated Swedish stove is ideal for energy-efficient and passive houses, as the heat loss through the floor are minimized. This is just a godsend for frame houses, which have a low heat capacity. In this case, UWB will be the foundation of storage tank in the building, and you will never karkasniku quickly cool down.

With the help of teaching materials FORUMHOUSE you can independently calculate the thickness of insulation, concrete, pillows and other parts of UWB for various types of buildings.

Installation of UWB - a preliminary stage 

Insulated slab may be mentioned Swedish advanced one conventional foundation slab, but like any foundation plate UWB requires preconditioning.

Vladimir Sidorov (Chief Engineer "Fundamentalno.rf")

Before the start of construction is necessary to obtain information on the ground in your area. Otherwise, it is impossible to determine the true foundation of any design or construction budget.

Determine the structure should not be to the customer, and design engineer who calculates loads and preparing a feasibility study. The purpose of the slab foundation - soil with poor load-bearing capacity, pile or a belt load in the home such soils are merely "fall" into the ground.

It is important to remember that UWB is a shallow foundation, and therefore requires addressing diversion of groundwater and the vadose. And be sure the device drainage system and the blind area.

That control the installation 

When routing communications in this type of foundation for the house should pay close attention to compliance with design solutions to how work is underway on the construction site.

It is important to all:

• Compliance reinforcement diameters and floor heating pipes;
• Mark materials used;
• Vertical and horizontal binding with a lining of communications;
• Lack of communication damage in the course of work on the installation and concreting.

Mikhail Leontyev:

All the characteristics of the materials used are determined by the project on the basis of calculations for a particular house and land. This also applies to engineering and construction part. Failure to comply with these parameters can lead to irreversible defects in the basement and laid it in communications.

end materials are selected depending on the weight of the house and its structure, which are used in UWB building: type of extruded polystyrene foam, concrete grade, a way of reinforcing stiffeners and the whole plate. If the site there is a difference of heights, then you need to perform before installing leveling foundation UWB.

Thus, for the construction of warmed Swedish plates need to solve a variety of complex tasks that require extensive knowledge, high quality materials and craftsmanship. But in the end it will allow you to become the owner of modern, energy-efficient, and most importantly - a comfortable home of your dreams.
