The Tefond membrane is a unique material that is made of extremely high density polyethylene and has a strong mechanical lock. Due to the unique structure, the individual elements of the membrane can be interconnected by the application of edges, which provides an integral barrier. The manufacturer took care of the presence of a special sealing compound, which guarantees the water-repellent properties of the surface.
Manufacturer Information
The Tefond membrane, the photo of which is presented in the article, is manufactured by the Tegola Kanadze concern, it was founded in 1976. He currently continues to work in the field of construction. The concern has three companies, one of which is engaged in the manufacture of roofing material, the other provides construction services, while the third is focused on the production of waterproofing materials. The company operates in countries with different climatic conditions, satisfying needs and wishes, which vary depending on many characteristics. All materials are safe, as they are monitored by independent experts and tested in the laboratories of the concern, which allows us to confirm compliance with established quality standards.
Drain Plus Membrane Specifications
The Tefond membrane, the manufacturer of which took care of the convenience of laying the material, is available in several varieties. One of them is Drain Plus, which is designed for waterproofing and drainage. One of the important problems is the drainage of rainwater to the base of the building foundation. The accumulation of excess moisture near the walls can cause an unfavorable indoor climate.
If there is no drainage material, then the gluing waterproofing will 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 Tefond Plus membrane and a fabric made of polypropylene. A geotextile fixed over the protrusions of the membrane provides an air gap that ensures reliable drainage of fluid to the drain pipe.
Technical characteristics of the classic Tefond membrane
The Tefond membrane is a new fastening system, which is implemented in a material that allows vertical stacking. This not only reduces the cost of welding, but also facilitates the calculation of a mechanical lock. If there is a need for total protection, then you should use such a geomembrane, which is represented by a canvas with protrusions in the form of cones. This allows you to create an air gap between the protective layer and the surface, which guarantees a drainage effect.
During use, excess moisture will be removed. The main purpose of the geomembrane is the protection of objects for various purposes from the negative effects of precipitation and groundwater. A series of membranes of the described brand is manufactured in rolls of standard size - 2.07 x 20 linear meters. This saves costly concrete in the preparation of foundations and floors.
On sale you can find varieties of the Tefond membrane, each of which differs in certain characteristics. For example, Tefond Plus has a compressive strength of 300 kN / m2, while Tefond Drain has a minimum compressive strength of 250 units. The maximum value of the mentioned parameter is peculiar to the Tefond HP product, which is characterized by compressive strength of 450 kN / m 2 .
Extra features
The Tefond membrane is one of the innovative developments in the field of construction. This polymer cloth can be laid quite simply and in the shortest possible time, as a result it will be possible to create a durable and reliable layer, the separation of the individual parts of which is almost impossible even under strong pressure. All models in this series act as an ideal barrier to vapor pressure, water and moisture.
Using a membrane, you can protect walls of any height, but do not make horizontal joints. It will be enough to fix only in the upper part, without drilling holes in the facade. For the reason 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, floors 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 material specifications
The Tefond membrane, the characteristics of which are described in the article, is easily used by the master when performing installation work. The material can act as an ideal preparation for installing floors on unprotected terraces, as well as flat roofs. Tefond is characterized by excellent physical and mechanical properties, which allows the material to undergo increased loads. That is why a membrane of this kind is used even as a foundation under a foundation.
High-quality insulation is guaranteed by a double lock, inside of which there is a bitumen sealant. Due to the presence of free air space between the wall and the canvas, a ventilation gap is provided that stabilizes the temperature and humidity conditions inside the premises. On sale today in a large assortment you can meet the products of the Tefond company. The membrane, the technical characteristics of which are presented in the article, should be laid with protrusions inside, if it comes to walls.
If you decide to equip a flat roof with this material, then the protrusions should be turned up, while the water will freely flow in the desired direction. Operation is possible at temperatures from -50 to +80 degrees, this allows you to work with the membrane in all weather conditions in any kind of natural belt. Its density is 670 grams per square meter, the material is intended for both internal and external work.
Vertical walling
The technology of laying “Tefond” (membranes) must be carried out by the master with high accuracy, only then it will be possible to achieve positive results. As soon as you measure the height of the walls that are intended for insulation, you should cut off a 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 connection. The coating should be placed as accurately as possible, the building level should be used for verification. Only after analyzing the correct placement should the material be attached to the wall, installing fasteners every 30 centimeters. Fixation should be in the upper part of the canvas. In this case, mounting washers should be used, which are installed in the second row of nests with an indent of 3 centimeters from the edge.
"Tefond" - a membrane, the installation of which can be carried out by you yourself. It is laid down from top to bottom, while moving from left to right. The master needs to start work from the edge of the wall, an alternative solution is the method in which you can step back 1 meter from any angle. This will cover it with a whole sheet.
Methodology
As soon as it is possible to ensure that the surface of the walls around the perimeter is closed, the first sheet of material must be connected to the last, providing an overlap of 40 centimeters wide. The excess membrane must be cut off, and the protrusions of one web must go into the nests of another. The resulting seam should be connected using a special tape.
Horizontal laying
The Tefond protective membrane is laid horizontally if the wall height is not more than 2 meters. Initially, the master will markup, mark a line on the wall. Turning the roll horizontally, you can start laying from the edge of the wall. Sometimes experts use technology in which one meter is indented from any angle. The distance between the nails should remain the same as in the method described above. The canvases are interconnected according to the method of imposing on each other at a distance of 20 centimeters or more. The protrusions on top of the canvas should go into the corresponding nests of the bottom. The seam is protected using the same tape.
Horizontal mounting
As soon as it is possible to measure the length of the surface to be insulated, the roll should be unwound and a sheet of the required length cut from it. The connection can be made using a simple or double lock, and the overlap should be made 20 centimeters wide. Cross seams must be offset by at least 50 centimeters relative to adjacent rows.
