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:Is the waterproofing membrane an insulating material?
There are many varieties of coil, the vast majority of the coil itself is insulated, mainly refers to the rubber, resin, asphalt. But the following are non-insulated: 1, PSS metal waterproofing membrane, which is the only coil in the whole metal coil, but the strict sense should not be included in the waterproofing membrane;
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:Roof SBS waterproofing membrane additional layer needs to be wide
Roof SBS waterproofing membrane additional layer width of 15-20cm, angle attached layer 25cm on each side. 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:What is waterproofing membrane?
According to the brand classification Construction industry waterproofing membrane mainly Dike waterproof membrane, DuPont waterproofing membrane, Sicon waterproofing membrane, which the first two participating GB chart set. According to its main waterproof composition material can be divided into asphalt waterproof material, high polymer modified waterproof membrane and synthetic polymer waterproofing membrane (SBC120 polyethylene polypropylene composite membrane) three categories. There are PVC, EVA, PE, ECB and other waterproofing membrane 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:Waterproof building materials after the construction of drums, bubble is what reason?
Causes and prevention of drums: Cause 1: If the membrane waterproof layer if the site is not solid, there is moisture, sunlight or artificial heat in the impact of the internal volume expansion, resulting in drums, the formation of the size of the bubble. Preventive measures: leveling layer should be kept flat, clean, dry, grass-roots treatment agent should be brushing evenly, which is to prevent the drum from the main measures. Raw materials in the transport and storage process, should pay attention to moisture and water. To avoid the rainy day, fog, big wind climate conditions under construction, to prevent grass-roots moisture. When the roof base should not be dry, and anxious to paving the membrane, the use of exhaust roof approach (exposed single layer of waterproofing membrane should not be used).
Q:1.2 thick synthetic polymer waterproofing membrane two weight how to count
Different materials of the coil its unit weight is not the same, and some polymer membrane with self-adhesive or empty shop, without adhesive, so according to the specific material and paste method for calculation, the above calculation, the exact calculation can be based on the actual The material was measured for its weight per unit weight and then the lap coefficient and binder were calculated.
Q:What is the material on the insulation layer on the waterproofing membrane?
3, the isolation layer before the use of paper gray or low-grade mortar, due to the construction of rigid layer, the pile of ash is easy to enter the concrete, so no. Low-grade mortar construction of the transport car on the waterproof layer of damage, and anti-slip performance is not ideal, so less used. Now generally use dry cloth linoleum together, but also useful thick plastic film and other materials.
Q:Why the roof of the waterproof membrane and insulation rock wool board to do between the isolation layer?
2, the insulation layer can be done on the waterproof above, according to the nature of insulation materials, insulation layer and waterproof layer can be set between the isolation layer or not set. If the waterproof layer on the laying of polystyrene foam board, do not need to do isolation layer; if the block of inorganic insulation materials, such as foam glass, waterproof layer should be set on the cement mortar protective layer; if the waterproof membrane to do Foam concrete or polyurethane block insulation, you can dry in the coil a linoleum for the protection of the isolation layer.
Q:Floor tiles on the terrace leak, can be directly on the brick shop SBS coil and then cast the cement?
4, SBS linoleum waterproof, when other waterproofing process is not suitable, you can choose SBS linoleum waterproof, and its advantages in: for a larger area and scope, more complex places, no regular terrace can be used, but the disadvantage is that SBS felt Waterproof is not extended, easy to aging, generally used in 3-5 years, and the construction should be very cautious, because the shop linoleum, the use of gasoline to spray the barbecue, it is easy to ignite the surrounding building materials, especially color steel insulation layer and Building insulation wall, are flammable materials, such as ignition, the consequences could be disastrous, so SBS linoleum waterproof as little as possible, with new materials to replace, even when used, be careful, do a good job before and after the construction arrangements.
Q:Is the asphalt waterproofing membrane facing the side?
3, Summary: normal self-adhesive waterproof, the bottom of the membrane bonding surface facing the surface, the wall toward the back of the water; pre-shop anti-stick, the bottom of the membrane surface facing the back surface, wall is also facing the water.
