What Does PVC Membrane Do?
It is a type of membrane used for insulation in water reclamation works. It is used to prevent water coming to building foundations, to prevent rainwater coming from outside on open terraces and to store water in water collection pool and pond applications.
PVC Membrane Types
Homogeneous PVC Membrane
PVC Membrane with Signal Layer
Reinforced PVC Membrane
Tunnel Type PVC Membrane
PVC is one of the most amorphous plastics. So there is no crystallization. Therefore, it is completely transparent. In this way, plastic additives can homogeneously penetrate the structure of PVC and integrate with PVC. With these additives, the properties of PVC can be combined in different ways. In this way, it can be used in many areas. More than half of the world’s PVC is used in the construction industry due to its long life, resistance to atmospheric conditions and durability. With the selection of appropriate additives, PVC can be processed at 180-200°C without decomposition. Shape changes of this plastic alloy are possible at low temperatures. In this type of processing, raw materials are combined to extrude pipes, hoses, profiles, foils and plates. Wires are coated, insulated guide rails are formed into cylindrical shapes, finished parts are spray-cast and hollow bodies are formed by blowing. PVC geomembrane waterproofing synthetic cover is a synthetic geomembrane waterproofing cover that can be produced with or without reinforcement, manufactured by melting and homogeneously shaping the mixtures obtained with stabilizers, plasticizers and dyes, mainly PVC, by extruder method. PVC waterproofing membranes, which have reached a level that can be called perfect in line with the developments in today’s technology, are an ideal waterproofing material that can be applied as a single layer for perfect waterproofing in many details. PVC geomembranes are produced in various thicknesses (1-1,2-1,5-1,5-1,8-2,0-2,0-2,5-3,0 mm) in various colors, single color or double color, as well as signal layered (one side with a thin yellow layer). It protects concrete surfaces exposed to corrosion, acids, alkalis, salts, gases and other chemical solutions, especially in corrosive substances. It is used as waterproofing and insulation material. PVC geomembranes also meet and even exceed many industry performance standards such as water tightness, puncture resistance, hail resistance, wind uplift resistance. For example; it is resistant to many threats such as rainwater ponding on roofs and air pollution, bird droppings, acid rain.
What are the Differences of PVC Membrane?
Thickness; 1 mm, 1.2 mm, 1.5 mm and 2 mm membrane can also be preferred in 2.5 mm and 3 mm thicknesses according to the amount in special demand. Type; It is related to the presence or absence of carbon reinforcement yarns between the two PVCs, i.e. homogeneity. Ultraviolet additive; Being resistant to the harmful effects of the sun or being UV-free, i.e. without additives. Place of use; It is selected according to its application in foundation and curtain application areas, agricultural irrigation pools, drinking water, chemical pools, fish farming, irrigation canals, open terraces or closed terraces and tunnels.
How to Use PVC Membrane?
PVC membranes are usually 2.10m x 20m or 2.10m x 25m but can also be produced in free lengths according to demand. Each panel is welded together at its width and length. The geomembranes opened in the application area are welded by hand welding machine or automatic heat robots by overlapping each wing of PVCs at least five centimeters (cm) on each other.
Considerations in PVC Membrane Selection and Application
The correct thickness should be determined according to the place of application.
In pool applications, the relevant tonnage (pressure) and height are very important.
In open terrace applications and insulation of curtain concrete walls, it is recommended to cover with geotextile felt, drainage board, XPS according to the place of application.
Welding joints of PVC membrane panels should be checked.
If PVC membrane is to be used in outdoor conditions, it should either be covered (free gravel, green roof applications, etc.) or have UV resistance.
If PVC membrane is to be used in open terrace applications, it must be UV resistant and additionally reinforced. In the application areas to be covered, it can also be preferred without UV or without reinforcement.
How is PVC Membrane Applied?
Method; 600-700 °C dry air can be welded with heat hand welding machines. Degree adjustment can be made on the machine. It is applied with manual labor.
Method; Application is made with semi-automatic or automatic dry air heat welding robot specific to the product to be applied with variable mouth end channels. Temperature and speed can also be adjusted in these machines.
Compressed air test can be performed upon request after PVC membrane application.
Where is PVC Membrane Used?
Reinforced concrete terrace roofs Light metal roofs Garden terraces Parking lots Foundation and curtain applications Floor slabs Wet areas Irrigation channels Artificial pond coatings Decorative ornamental pool coatings Drinking water tanks
Fire water tanks
Roof rainwater gutters
Domestic water tanks
PVC membrane usage is common.
