Product Description:

EVA waterstops


Products Description

PVCEVA waterstops is made of high grade polyvinyl chloride and features unique design and advanced

process. It is applicable for various joints during construction and use. Simple use and easy combination

in construction site.

Products Specification

Thickness :1.0-4 .0 mm
Width :15-30CM
Length: 20M

Features

● PVC, EVA waterstops for sealing construction and expansion joints of reinforced concrete (expansion joint),

placed in the concrete water stop, across and close the gap, forming a solid watertight seamless screen, to

prevent fluid flow through .
● PVC, EVA waterstops with a variety of different shapes, such as middle and external design, in any ground

or underground construction, the formation of a long and solid watertight network, especially for water and

retaining the the structure.

Installiton

PVC water stop rubber water stop with the same installation method. When buried in the poured concrete interface

to make it fit with the flat part of the adhesive fastening joints, buried in the process of pouring the power to appropriate

the full vibrating the concrete, making it a good combination with concrete, in order to obtain the best sealing effect .

Application Range

Different shapes of PVCEVA Waterstops centrally and extermally placed allow lasting watertight seals in any grades

of construction design. They are typically used in water retaining and excluding structure, such as reservoirs, sewage tanks,

dams, pools, basements,subway, tunnels retaining walls, etc.

Q:What is the difference between construction non-vulcanized waterproofing membrane and vulcanized waterproofing membrane?
Non-vulcanized rubber waterproofing membrane: from SR or SR and asphalt blends by mixing, rolling made of coil, without vulcanization can use the product. The bonding between the coils and their bonding properties with the mortar is good, the manufacturing is convenient, the price is low, but the tensile strength is low. Can be divided into two types of rubber and rubber asphalt. Rubber type commonly used SBR and other SR production. Generally used for civil construction roof waterproof.
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 meaning of "channel" and "layer" in the practice of polymer waterproofing membrane?
In addition, the two did not meet the required thickness of the waterproof layer, according to certain requirements for laminated composite, two waterproof layer can be considered a waterproof. Such as 1.2mm polyurethane + 1.2mm self-adhesive coil (laminated construction rather than separate), can be used as a waterproof, although with two kinds of materials to do a two-story waterproof, and can not be considered two waterproof. The thickness of the laminated composite waterproofing layer can be thinned, and its provisions may be reflected in the new "roofing engineering technical specification" to be published.
Q:Sbs modified asphalt waterproof membrane polyester type Ⅰ type Ⅱ how to distinguish
These two kinds of materials from the current surface is exactly the same, if it is experienced people, you can through the tension on the sheet asphalt to determine the initial situation, if the domestic refrigerator can reach -25 ℃ low temperature, can also be low temperature flexibility Not broken after the initial judgment). To correctly determine the need for sample inspection.
Q:Is the asphalt waterproofing membrane facing the side?
Because there are many types of self-adhesive waterproofing membrane, their use and construction methods are different, there are two main methods. 1, the normal self-adhesive paving method: the film directly paving or polymer cement cement wetting method, paste in the grass-roots level. The bottom of the floor floor of the building, in the concrete cushion with cement mortar leveling, and then the coiled surface of the membrane down, paste in the leveling layer, the roll surface pouring 50 thick stone concrete protective layer, Floor concrete. Wall construction, the film directly attached to the basement wall panels, and then do the protective layer on the outside. Commonly used modified asphalt self-adhesive waterproofing membrane, modified asphalt wet sheet is usually used in this method.
Q:SBS modified asphalt waterproofing membrane and synthetic polymer membrane the same, not the same, what is the difference?
fiber fabric or fiber felt For the carcass, powdery, granular, flake or film material for the cladding material made of curled sheet waterproof material. The use of the construction process is cold construction paving or hot melt paving.
Q:Roof SBS waterproofing membrane can not empty shop
Whether the waterproofing membrane is empty is determined by two aspects. 1, the construction site requirements. Such as the basement of the bottom of the membrane waterproof specifications require empty shop; deformation of the steel roof can be a small amount of sticky open shop or shop shop to adapt to structural deformation, but the coil to have a certain pressure.
Q:Pvc waterproof membrane of the scope of application
6, light color of the surface reflection of ultraviolet radiation, the surface of the membrane to absorb less heat, low temperature; 7, long life (roof 25 years, more than 50 years underground), and no environmental pollution; 8, the details of processing is very convenient, easy maintenance, low cost.
Q:What is the resistance type SBS waterproofing membrane?
The third is the combination of the above two principles. SBS resistant root puncture membrane has three kinds: 1, composite copper fetal base SBS modified asphalt waterproofing membrane. Mainly using copper tires to puncture strength, while copper ion drive plant roots. 2, copper foil tire SBS modified asphalt waterproofing membrane. Mainly the use of copper ion drive plant roots, while a certain anti-piercing strength. 3, SBS modified asphalt root resistant puncture waterproofing membrane. Mainly chemical resistance to root.
Q:What is called a waterproof roll dry shop, wet shop
The biggest difference between the two is the same bonding strength, wet pad bonding strength is much larger than the dry shop method.
