Permanent formwork for the foundation

Those who were fortunate enough to engage in self erecting their own home from scratch, it is well known what a huge role played by his foundation device process, and in particular - the installation of the formwork.

Simplify the job as possible, using such an achievement building technologies as permanent formwork for the foundation.

device and advantages

This device is a system of individual elements or blocks, gathering in one-piece construction that is installed directly into the site of the future location of the foundation.

For its creation, use different materials, but the most common is a permanent formwork for the foundation of the Styrofoam and polystyrene.

This first biggest advantage is its low weight, the ability to retain heat well, and relatively low cost.

Polystyrene also has a higher strength, but has a larger whole, and slightly worse thermal insulation properties.

much less used one more version, manufactured from fibrolite plates, representing a mixture of cement and wood chips.

In this case, the presence of the tree at its base is a positive quality (this material retains heat better) and a disadvantage (such filler lifetime is much shorter synthetic analogs).

Well suited for creating complex and curvilinear designs.In addition, assembling and allowed fibrolite structures at fairly low temperatures.

Fixed timbering for strip foundation from expanded polystyrene has a cavity inside which is fitting, providing a better structure rigidity and reliability.

the same purpose using cross bridge type in aligning blocks which prevent the occurrence of deformation during the pouring of concrete mixture therein.

Foundation for the permanent shuttering, in addition to the speed and ease of construction, has a very significant and undeniable advantage.

Unlike variant removable type, he is already at the stage of installation has good insulating properties, which saves on further measures for its thermal insulation and soundproofing.

use of this kind of design provides better stability to the building being erected possible shrinkage and soil shifts.

In addition, through the use of non-removable formwork type, ensured the best savings concrete solution and guarantees a high precision of work on the construction of the foundation.

installation features and disadvantages

Building the foundation of permanent shuttering is quite a simple process that does not require special training and skills.

Usability to this structure from the perfect coincidence of the geometric parameters of its elements and the presence of special tool joints, through which the connection block takes place without the use of special mixes and solutions.

Thus, it is possible to build the foundation of any type, but more preferred embodiments can be called a monolithic or prefabricated concrete foundations.

mounting process is a connection between the individual structural elements, after which it is filled with metal reinforcement and poured concrete.

The main difficulty in this case is laying out the first row of blocks.

In so doing, care must be taken to ensure that all taps interior partitions, soffits were placed on the right locations which correspond to the project.

Fixing design forms occurs during installation of its second series.

It is important to monitor the exact match of its lateral and vertical joints, laying blocks on the basis of the children's designer, or masonry.

addition to the undoubted merits, concrete permanent formwork for the foundation has some "weak points".

Among them we can mention:

• «Fear" stay under the open sun.When a long stay in such conditions polystyrene becomes brittle and can crumble;
• need to involve special construction tools, for example, the construction of the vibrator, which serves for a better distribution of the concrete structural elements within the solution;
• necessity of additional devices waterproofing layer;
• impossibility of re-use;
• high cost.

What are the prices and where to buy?

On the last point is somewhat elaborate.

Despite the fact that the high price of permanent formwork for the foundation, in fact, is the most serious drawback, this small minus does not detract from the other benefits of this innovative device, making the process of building the house more comfortable, high-quality and modern.

Given the fact that the cost of the wooden planks used for the installation of shields classic, removable formwork, can not be called low, and taking into account the complexity of the process for its manufacture and subsequent pouring of the foundation, it can be concluded,removable version that is more efficient and practical.

Buy permanent formwork for the foundation can be in the appropriate retail outlets engaged in selling products of this type.

Find it may be, and on the websites of specialized online stores, focusing on the amount of the order of 850-2500 rubles for individual elements of the design and 69-450 rubles for fixing parts and accessories.
