PVC Waterstops Clinic Beton Iran

Waterstop PVC is a side piece that is installed in the implementation of concrete structures with the purpose of sealing the operational and expansion joints of hydraulic structures or exposed to water. For various technical and economic reasons, concrete and concrete structures have been used to store, direct and transport water since the distant past. Embedding contraction and expansion joints to control the structural behavior of concrete and prevent cracking in large and bulky sections on the one hand, as well as operational limitations and the necessity of placing operational joints or cutting concrete on the other hand, are the main factors of the need for water or submerged concrete structures to The use of waterproofing materials and materials are in the mentioned sections. For this purpose, Waterstop waterproofing tapes (Waterstop PVC) are widely used. Waterstop waterproofing tapes must have high flexibility to adapt to the dimensions and volume of concrete structures, and with the complexity of the type of sections and execution conditions, and according to the dimensions and sizes of the structure in terms of thickness, width, type of treads and hole changes. and... be designed. Among the most important quality features of Waterstop is the percentage of elongation, tensile strength and hardness, which must comply with standard requirements. Also, the durability of Waterstop in various conditions, including alkaline environments, is important and should be taken into account, otherwise, Waterstop in an alkaline concrete environment will quickly lose its quality and undergo a change in state, leading to leakage and other problems. Quality problems such as cracking and settlement of the structure, etc. Waterstop PVC is used in sealing dams, treatment plants, water transfer tunnels, tanks and channels, buried structures, semi-buried structures and structures below the level of underground water. Waterstops are made of different materials, each of which has its own unique characteristics. According to these characteristics and in accordance with the characteristics of each structure, the material of the desired water stop is selected. Waterstops actually work by lengthening the flow path of water and other liquids so that they cannot penetrate the concrete. Waterstops have treads that provide more grip and increase the distance.

Uses of PVC Waterstops

It is used in the joints of concrete structures that are exposed to hydrostatic pressure and in direct contact with water and liquids, such as swimming pools, ground water sources, sewers, tunnels, dams, water supply channels and all kinds of foundations.

Properties and effects of PVC Waterstops

PVC waterstops have very high tensile strength due to the use of special materials. Also, the lifespan and durability of this PVC water stop is very high and they will not have any problems for many years. They are highly malleable and this makes them usable in many moving joints. High impermeability of these materials is also their very important feature. Its high resistance to acids, ozone, sea water and even diesel oil makes it very durable and long-lasting. They are also resistant to alkalis, chlorine-containing water and other water-soluble chemicals. Like metal or rubber, they do not suffer fatigue deterioration. They do not change color in contact with concrete. It does not show electrolytic reaction with its adjacent metals. They have the ability to withstand hydrostatic pressure. They have a very high resistance to heat. They can also withstand changes in size during temperature changes, this happens due to the high elasticity of these materials.
Waterstop is used in order to prevent water from leaking and passing through executive, expansion joints, as well as sections of concreting, which changes in size and shape depending on the type of section used and fluid pressure.

Features and specifications of PVC Waterstops

The agent that prevents the passage and penetration of liquids from the concrete joint and is resistant to acids and alkaline substances. Waterstop type (O with holes) is used for expansion and contraction joints, and in terms of the middle cavity of the waterstop and the ability to change its shape, it prevents the passage of water. Due to the displacement of the seams, it is resistant to hydraulic pressure as well as longitudinal displacement, stretching and contraction. Waterstop type (flat E) is used for construction seams, and the task of this type of type in executive seams is to prevent the passage of water inside the seams. Rod Waterstop Tip (Flat back holed OF) is used for expansion joints in the floor. Waterstop type (EM dumbbell without hole) is used for execution joints with high static pressure. Waterstop type (OM dumbbell with hole) is used for expansion joints with high pressure. Waterstop types K, L, V are used for concrete corners.

How to use PVC Waterstop

In order to install PVC Waterstops, make sure that this strip is placed in the middle of the concrete and use clamps, clamps, wire and wire to restrain and keep the strip in place. Be careful to pour the concrete slowly so that the waterstop does not separate from the installation site. Waterstop should be protected against any oil and pollution and UV rays. The width of the waterstop should not be greater than the thickness of the concrete and the distance from the concrete surface to the waterstop should not be less than half the width of the waterstop. The width of the water stop should be at least six times larger than the size of the sand.

How to connect two pieces of waterstop

The joints of the two ends of the waterstop can usually be connected in two ways, three ways and four ways, as well as vertically and horizontally. The use of these connections, while increasing the reliability factor for sealing, also performs the welding of the two ends of the waterstop well. There are two ways to connect the two ends of the waterstop:

1. With the help of Hoya machine (waterstop iron), heat the two ends of the waterstop until it melts, then place the two ends of the waterstop on top of each other to make the connection, which will come together after cooling down.
2. The two ends of the waterstop are connected by means of industrial adhesives that are suitable for connecting soft PVC, in such a way that approximately 30 cm of the two ends of the waterstop are placed on top of each other in the form of an overlap and the middle of them is smeared with the desired glue. and put under pressure to completely absorb each other.
