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:What is the difference between polymer waterproofing membrane and cross film waterproofing membrane?
Quanzhou strong cross-membrane waterproof membrane and polymer waterproofing membrane of the difference, the main component is not the same: strong cross-membrane is a polyethylene film, polymer is a polymer homogeneous film. You can choose Yu Xiang card UFW-C strong cross-membrane reaction bonding waterproofing membrane, Fujian Yu Xiang waterproof material Technology Co., Ltd. is a research and development, production of building waterproof materials and waterproof engineering to undertake the building waterproof system service providers!
Q:What are the requirements for frost resistance of basement floor polymer waterproofing membranes?
High polymer modified asphalt waterproofing membrane is -30 degrees.
Q:What is the difference between pressure-sensitive self-adhesive waterproofing membrane and sbs asphalt waterproofing membrane?
3, from the price   Pressure-sensitive self-adhesive waterproof membrane price is more affordable, quality assurance, as if there is a good product of home, such as macro cattle Xugong, the price is more affordable, quality assurance. And sbs asphalt waterproofing membrane is more expensive.
Q:What is the preferred level of waterproofing?
, roof level 1 waterproof: Application: particularly important or waterproof with special requirements of the building; Waterproof layer of reasonable use of life: 25 years; Waterproof layer selection of materials: should use synthetic polymer waterproofing membrane, polymer modified asphalt waterproofing membrane, metal sheet, synthetic polymer waterproof coating, fine stone concrete and other materials; Fortification requirements: three or more than three waterproof fortification.
Q:Pvc waterproof membrane of the scope of application
3, with good weldability, seam hot air welding and the substrate into one; 4, with good water vapor diffusion, condensate easy to release; 5, low temperature flexibility is good, to adapt to the environmental temperature difference is good;
Q:It is good for black roof with waterproof paper
SBS surface is divided into: PE film, no film, Liao film, sand surface, shale surface and other categories. The blacks mentioned in the problem belong to PE film and no film, and the silver is the membrane of the membrane. There is no difference between the use of good or bad comparability.
Q:Roof SBS waterproofing membrane additional layer needs to be wide
Asphalt waterproofing membrane is in the base tire (such as base paper, fibrous fabric) dip on asphalt, and then spread in the surface of powder or sheet of the isolation material made of curled sheet waterproof material.
Q:Elastomer modified asphalt waterproofing membrane for what purpose? Need to pay attention to a few things?
Second, the construction quality Full adhesion to prevent wrinkles or hollowing; semi-adhesive attention to the unbonded to under fire, so that the membrane close to the base surface; empty shop attention around the adhesive, and pressurized. Hot melt adhesive, with the fire to be appropriate to the surface of the coil is not subject to black, avoid slow baking. Winter construction selection of low temperature flexibility than the construction temperature of 10 ℃ lower temperature products, and the coil stored at 0 ℃ above the place before use into the scene, handling to prevent throwing throw.
Q:Polyurethane and SBS membrane waterproof
Paste asphalt linoleum. The cold binder material prepared by diluting the bitumen with solvent is developing. Various solvent and water emulsion asphalt or asphalt rubber coatings for roof waterproofing, should be strictly selected anti-cracking, tensile, anti-aging performance and good weatherability thick coating varieties. In addition, all kinds of ointment for dealing with the general building of the joints waterproof.
Q:SBS waterproofing membrane how to sample
SBS modified asphalt waterproofing membrane, APP modified asphalt waterproofing membrane: the same manufacturers, the specifications are not more than 10000m2 for a number of qualified qualified coil, each batch of random 1
