How to attach a membrane?
Sometimes it is difficult to choose equipment for pvc membranes. A forum on the topic, of course, can help with the decision, but can you guarantee the competence of the councils?
Typically, in such forums, as a way to attach the membrane, you can be advised to weld. With the help of weld, the roofing materials melt, under the influence of high temperature, and stick to each other. At the same time, the main thing is "do not overheat", otherwise the strength of the material may decrease. After fusing, the material must be strongly pressed, i.e.apply high pressure. This will allow you to "mix" the layers.
The most convenient way of heating is with the help of hot air.
With this method you do not have to wonder: how can I protect the pipe when laying the roofing? Especially for the protection of pipes when heated by hot air, filler material is used.
It is important to understand the structure of the membrane itself when assembling a polymer membrane. For example, a specialist in the store advised you geotextile heat-treated technonikel weighting 150 g / m2., 1.6 mm. But what does it mean?
The design itself is presented as a "pie", which consists of:
- Ballast
- Geotextiles
- plates Thermally treated geotextile 150 g / m2
- Polymer membrane
- Another layer of geotextile
- CCD
- Base
High density 150 g / m2 will provide you with excellent protection, and a thickness of 1.6 mm will not allow the destructive effect to penetrate into the structure.
Sometimes it is necessary to lay a backing layer( when laying on a rough surface).
After we sorted out the "pie", you may have a question and why do you need a separation layer between the polymer membrane and styrene foam?
Separation layer
The separation layer is usually made of glass wool. This is a roll material consisting of fiberglass. It can serve as a reinforcing base, i. E.it is good to resist stretching( longitudinal movements).But it is necessary to take into account the important fact - the fiberglass should not be fixed on a concrete covering and CSP( cement-sand screed) in any case.
Therefore, for laying on the concrete floor of the plates, a waterproofing is necessary. Plates of the technoplex are laid down with an inscription downwards. And on top already lay a layer of fiberglass
Doing your own hands
Completely figuring out the composition of the technonikol, you finally decided to begin the process of laying. So, how to work with a technologist?
First of all, it is necessary to consider the following factors: the slope of the surface and the material. The ambient temperature should not be below 5 degrees. In contrast, tiles may not stick together. Also do not forget about the humidity, the surface must be absolutely dry. Also avoid exposure to sunlight( ultraviolet radiation).
Also, do not forget about the overlap - it can vary from 100 to 300 milimeters, depending on the width and strength of the material. 
If we talk about the plates of the technology, then they apply the same preconditions( temperature, humidity) as for membranes.
By the way, the technoplex can already be laid on concrete or cement. A special plus - the Technoplex is not subject to the action of water( thanks to the closed-cellular structure), that is, it does not swell and does not decompose.
Such slabs are used for various tasks, such as pedestrian roofs, protect the foundations and socles of cottages. Isolation of the base allows you to prevent serious heat loss, to protect the foundation from rain and groundwater.
In fact, the technoplex is indispensable for isolating the floor of the lower floor and the basement.
Also for external protection can be used another roofing material - isobond. Its low price, and for example the isobond in Stavropol costs 1050 rubles per roll, and its excellent properties make it a popular enough material. 
Isobond is used for steam, hydro, moisture, wind, hydro-steam insulation.
Isobond is divided into brands A, B, C, D, AM.Each of these brands has different water resistance, vapor permeability and resistance to breaking load. In fact, you can pick up the material for your personal needs.
In the modern world, there are many ways to protect your property from adverse circumstances. But before buying the material itself, we advise you to read the relevant materials. For example, to hammer in the search line "equipment for pvc membranes forum".
