Membrane "Tefond": technical characteristics, installation, stowage technology, manufacturer, photo

The membrane "Tefond" is a unique material of its kind, which is made of extremely high density polyethylene and has a strong mechanical lock. Due to the unique structure, individual membrane elements can be joined together by overlapping edges, which provides an integral barrier. The manufacturer has taken care of the availability of a special sealing compound, which guarantees the moisture-repellent properties of the surface.

Manufacturer Information

The membrane "Tefond", the photo of which is presented in the article, is made by the concern "Tegola Kanadze", it was founded in 1976. Currently, he continues to work in the field of construction. The concern has three companies, one of which is engaged in the production of roofing material, the other provides construction services, while the third is aimed at the production of waterproofing materials. The company works in countries with different climatic conditions, satisfying the needs and wishes, which differ depending on many characteristics. All materials are safe, as they are controlled by independent experts and are tested in the laboratories of the concern, which allows to confirm compliance with the established quality standards.

The characteristics of the membrane "Drain Plus"

The membrane "Tefond", the manufacturer of which took care of the convenience of laying the material, is on sale in several varieties. One of them is Drain Plus, which is designed for waterproofing and drainage. As one of the important problems is the drainage of rainwater to the foundation of the building. Accumulation of excess moisture at the walls can cause an unfavorable indoor climate.

If there is no draining material, the waterproofing will prove to be damaged, which will lead to leaks and create a danger to the bearing walls of the building. "Tefond Drain Plus" is a coating that consists of a membrane "Tefond Plus" and a cloth made of polypropylene. The geotextile fixed over the protrusions of the membrane provides an air gap, which guarantees a reliable drain of the liquid to the drainage pipe.

Technical characteristics of the classical membrane "Tefond"

The membrane "Tefond" is a new fastening system, which is realized in a material that allows for vertical laying. This not only reduces the cost of welding, but also facilitates the calculation of the mechanical lock. If there is a need for total protection, then a geomembrane should be used, which is represented by a web with projections in the form of cones. This makes it possible to create an air gap between the protective layer and the surface, which guarantees a drainage effect.

In the process of use, excess moisture will be output. As the main purpose of the geomembrane is the protection of objects of different purposes from the negative effects of atmospheric precipitation and groundwater. A series of membranes of the described brand is made in rolls of standard size - 2.07 x 20 linear meters. This allows you to save expensive concrete in the preparation of foundations and floors.

On sale you can find a variety of membranes "Tefond", each of which has certain characteristics. For example, Tefond Plus has a compressive strength of 300 kN / m2, whereas Tefond Drain has a minimum compressive strength of 250 units. The maximum value of this parameter is characteristic of the product "Tefond HP", which is characterized by compressive strength of 450 kN / m ² .

Additional features

Membrane Tefond is one of the innovative developments in the field of construction. This polymer canvas can be laid quite easily and in the shortest time, eventually it will be possible to create a durable and reliable layer, the separation of individual parts of which is almost impossible even under strong pressure. All models of this series act as an ideal barrier to the pressure of steam, water and moisture.

Using a membrane, you can protect walls of any height, but do not do horizontal joints. It will be enough to fix only in the upper part, without drilling holes in the facade. Due to the fact that the Tefond membrane is manufactured in standard sizes, this makes the arrangement of protection as convenient as possible. Laying can be carried out in the field of foundations, roofs, interfloor overlappings of any size. The excess part of the canvas can be cut off, and when storing rolls, users have the opportunity to reduce storage space by 50% or more.

What else you need to know about the characteristics of the material

The membrane "Tefond", the characteristics of which are described in the article, is easily used by the master when performing assembly work. The material can act as an ideal preparation for the installation of floors on unprotected terraces, as well as flat roofs. "Tefond" is characterized by excellent physical and mechanical properties, which allows the material to undergo high loads. That is why a membrane of this kind is used even as a foundation for a foundation.

Quality insulation is guaranteed by a double lock, inside of which is a bitumen sealant. Due to the presence of a free air space between the wall and the canvas, an air gap is provided that stabilizes the temperature and humidity conditions inside the premises. On sale today in a large range can be found products of the company Tefond. The membrane, the technical characteristics of which are presented in the article, should be laid inside the projections, if it is a question of walls.

If you decide to equip a flat roof with this material, then the ledges should be turned upwards, and the water will flow freely in the desired direction. Operation is possible at a temperature of -50 to +80 degrees, this allows you to work with the membrane under any weather conditions in any kind of natural belt. Its density is 670 grams per square meter, the material is designed for both internal and external works.

Vertical laying on walls

The technology of stacking Tefond (membranes) should be carried out by the master with high accuracy, only then it will be possible to achieve positive results. Once you measure the height of the walls that are intended for insulation, you should cut off the sheet of material of the desired length. It is important to make sure that the support tabs are on the right side, they should be located in the central part of the joint. The coating should be placed as accurately as possible, to use the construction level. Only after analyzing the correct placement should you attach the material to the wall, installing fasteners every 30 centimeters. Fixation should be carried out in the upper part of the canvas. In this case, use washers that are installed in the second row of pockets with an indentation of 3 centimeters from the edge.

"Tefond" is a membrane that can be erected by yourself. It is stacked from top to bottom, while moving from left to right. The master needs to start work from the edge of the wall, as an alternative solution is a method in which you can retreat 1 meter from any angle. This will cover it with a whole sheet.

Methods of work

Once it is possible to achieve that the surface of the walls along the perimeter was closed, the first sheet of material should be connected to the last, providing a lap width of 40 centimeters. The surplus of the membrane must be cut off, and the protrusions of one leaf must go into the nests of the other. The resulting seam should be joined using a special tape.

Implementation of horizontal laying

The protective membrane "Tefond" is laid horizontally in the event that the height of the walls is not more than 2 meters. Initially, the master has to make markings, mark the line on the wall. Unfolding the roll horizontally, you can start laying from the edge of the wall. Sometimes experts use technology, in which from any angle an indent is made in one meter. The distance between nails should remain the same as in the method described above. Cloths are connected by a method of overlapping one another at a distance of 20 centimeters or more. The protrusions on the top of the placed web should go into the corresponding sockets of the lower one. The seam is protected with the same tape.

Mounting on a horizontal surface

As soon as you can measure the length of the surface, which should be isolated, you need to unwind the roll and cut off the sheet of the desired length from it. The connection can be made with a simple or double lock, and the overlap should be made 20 cm wide. Cross seams should be displaced relative to adjacent rows by at least 50 centimeters.
