Introduction of PVC Waterproofing Membrane:


PVC Self-adhesive Waterproof Membrane is a kind of synthetic polymer waterproof membrane which made from polymer self-adhesive polymer, uses Polymer sheet(PVC) as the original source. It has high tensile strength, perfect elongation, excellent resistance to punture and tear, the greatest feature the material is: Concrete can be pasted directly on the membrane surface, after the concrete has been setted, bond strength of membrane and concrete is greater than 2.0Mpa so as to solve the problem of membrane channeling water and leakage.

 

Features

1.High Tensile strength, excellent resistance to tear and puncture.

2.Strong adhesion with the concrete, effectively prevent the emergence of a single polymer sheet phenomenon of channeling water.

3.Lap with pre- self-adhesive side lap to ensure the seamless of waterproof system.

4.Perfect resistance to acid&alkali,weather and aging.

5.Simple operation, High work efficiency, Low cost.

6.Non toxic, tasteless and be environmentfriendly.

 

Scope of Application

  1. Large-scale underground structures.

  2. Surface of concrete slabs for planting.

  3. For Roads, Rails, Subway tunnels projects.

  4. For reservoirs, canals, dams and other water conservancy projects.

  5. For air defense, military facilities waterproof projects.

Construction technology

  1. Tunnels, bridges should use polmer sheet welding lap joints. Firstly, pre-paved polymer sheet side of polymer self-adhesive composite waterproof membrane toward the base, and fix it with dedicated pieces of machine, double lap weld seam welding machine should be used for lap joints. Tear off insulation paper, band reinforced concrete directly, self-adhesive waterproof membrane will adhere to the main body of concrete structure closely to achieve full adhesion.

  2. General building underground projects should use self-adhesive overlap method. Basement bottom: pre-laying the membrane on cushion firstly(polymer sheet face down), tear off reserved isolation paper of lap joints self-adhesive side and can be sealed when paste directly; tear off isolation paper of self-adhesive waterproof layer, structural concrete, the membrane will anti-stick to the concrete structure to form dense waterproof system.

  3. Basement side wall, Surface of concrete slabs for planting: attach the self-adhesive material side to the base surface directly, tear off reserved isolation paper of lap joints self-adhesive side. Side wall shall be fixed with dedicated pieces of machine.

  4. Half header treatment:Wether horizontal half header or vertical half header, which should be sealed with sealant, membrane in the elevation without groove half header, it shall be fixed with metal straps firstly, then seal the top hole of metal straps and fixed screw with sealant.

Q:Whether the polyester waterproofing membrane can be used for roofing waterproofing
2, roof waterproofing is not just a layer of waterproof membrane, according to the design of the coating is usually used waterproof layer + polyester membrane waterproof layer;
Q:Construction Measures for Waterproof Coil in Winter
2. Master the hot melt paving points. Hot melt coil construction requirements of the heating width should be uniform, heating nozzle from the coil surface to be appropriate, 0.5m or so. Winter construction temperature is low, hot-melt time than the room temperature to be more, hot-melt to the surface of the membrane is bright, or melting is not enough. Such as beyond the degree of light overheating melting, the polymer modified asphalt easy to aging zoom, adverse bonding, but can not penetrate burned, grasp the hot melt to be strong bonding. When the sheet is rolled, the seam must be spilled over the adhesive to verify that the paste is tight, and the spilled adhesive is scrapped and the necessary measures to strengthen the seam. Coil large hot melt paving the same attention should be paid to the air inside the coil.
Q:How is the water level rated and how many grades are used?
Roof waterproofing level, mainly the ability of roof waterproofing, to distinguish between the various levels, generally based on the construction process and the choice of waterproof material. Waterproof at all levels of specific materials do not have clear requirements, as long as the water resistance and service life can be achieved.
Q:On the roof of the waterproofing membrane paving the direction of what are the requirements
 As for the upper and lower layers are not allowed between the vertical paving, the reason is that after the paving more heavy joints, and heavy seam is the most vulnerable to leakage of weak parts.         Dragon waterproof experts to remind you: things always have a dual nature. In the southern region, the temperature is high, rainy days, to the web paving brought a lot of difficulties. In order to waterproof roofing, when the rain is easy to coil joints, in addition to less than 3% of the roof slope, the remaining slope of the roof coil should take the vertical roof direction paving.
Q:Why is the top cover of the basement waterproofing? While the floor has to empty shop?
Waterproof membrane is mainly used for building walls, roofs, as well as tunnels, highways, landfills, etc., to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials, as the basis for engineering And no leakage between the building connection, the entire project is the first waterproof barrier, the entire project plays a vital role. The main products are asphalt waterproofing membrane and polymer waterproofing membrane.
Q:The difference between high polymer modified asphalt waterproofing membrane and sbs
SBS modified asphalt waterproofing membrane is a kind of polymer modified asphalt waterproofing membrane, which is included with the included relationship.
Q:Polyurethane and SBS membrane waterproof
 Methyl methacrylate (methyl acrylate), acrylamide (acrylic), polyurethane (cyanide) as the base material of the grouting material can be used for underground engineering plugging waterproof.  Because plastic in the sun is easy to aging, so used in underground engineering, and polyurethane can be made of liquid, used to plug the water.
Q:SBS Shale Waterproof Coil
SBS modified asphalt waterproofing membrane, this coil has a good high temperature performance, can be -25 to +100 ℃ temperature range of use, a higher flexibility and fatigue resistance, and up to 1500% Elongation and strong puncture resistance, tear resistance. Suitable for cold areas, as well as deformation and vibration of large industrial and civil buildings waterproofing works.
Q:3MM thick, one square meter waterproof membrane SBS price?
4, SBS modified asphalt waterproofing membrane is SBS rubber modified petroleum asphalt cited as the invasion coating, polyester fiber non-woven fabrics, jute cloth, fiberglass mats were made for the fetal base, to plastic film for the defense Sticky isolation layer, by the selection, ingredients, eutectic, invasion, composite molding, curling and other processes processing production.
Q:Can waterproof sheets be used on steel roof panels?
to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials , As the engineering foundation and the building between the no leakage connection, is the entire project waterproof first barrier, the whole project plays a vital role.
