PVC waterstop tapes are an important building material used to ensure water tightness in reinforced concrete structures. It is used at the joints of foundations, curtain walls, slabs and other reinforced concrete elements. It has a flexible structure that can adapt to the expansion and contraction movements of concrete. In this way, it prevents water from leaking in by closing the gaps between concrete elements. It is also resistant to chemical substances and weather conditions. Thanks to these features, they offer a long-lasting and reliable waterproofing solution.
Waterproofing with PVC Waterstop Tape
PVC waterstop tape is a material used to ensure water tightness in construction joints formed between expansion and contraction joints in reinforced concrete structures and concrete poured at different times and to prevent damage to the structure.
Advantages
- It has high tensile strength to adapt to the movements of concrete.
- PVC waterstops have high elongation properties. In this way, it adapts to the expansion and contraction movements of concrete and protects the seal.
- It has excellent intrinsic elasticity and impermeability.
- High resistance to acids, ozone, seawater and even diesel.
- Resistant to alkalis, chlorinated water and other water-based chemicals.
- It is manufactured from high quality materials and meets industry standards.
- It does not cause electrolytic effect on surrounding metals. In this way, it can be used safely in applications where different materials are used together.
- It protects the seal by resisting the pressure of water.
- It can be easily installed and joints can also be sealed.
- Maintains tightness by adapting to movements caused by temperature changes or different placement of the foundation.
- It can be easily mounted.
- It can be easily used in different application areas.
Areas of Use
- Bridges
- Tunnels
- Subways
- Pools
- Channels
- Sewers
- Water Tanks
- Dams
- Pools
- Treatment Plants
Application
- Application surfaces must be clean, dry and smooth. If necessary, roughness is removed and the surface is leveled.
- Waterstop tapes are cut in sizes suitable for the application area. Special pieces can be prepared for corners and joints.
- The bands are attached to reinforced concrete surfaces with adhesive or mechanical fixing methods. It is important that the bands are positioned correctly and placed tautly.
- The ends of the tapes are welded together using hot air welding or special adhesives. The welding must be done carefully to create a watertight joint.
- After the application is completed, water tightness is checked by testing. If necessary, water leaks are eliminated by taking additional measures.
Points to consider
- Tape selection should be made in accordance with the characteristics of the application area and water pressure.
- During the application, occupational safety rules must be followed and necessary precautions must be taken.
- It is very important that the tapes are correctly positioned and that the welding process is accurate.
- After the application, testing and control procedures must be carried out and possible problems must be eliminated.
What is PVC Waterstop Tape?
PVC waterstop tapes are an important building material used to ensure water tightness in reinforced concrete structures. Made of polyvinyl chloride (PVC), these tapes are placed in joints during concrete pouring to prevent water from penetrating into the structure. It is widely used in foundation-curtain wall joints, water tanks, swimming pools, subway and tunnel structures.
The main function of these tapes is to prevent water infiltration through cracks and joint gaps that may form over time in reinforced concrete structures. Such gaps, caused by the expansion and contraction of concrete over time, can allow water to enter the structure and cause corrosion and other damages. Thanks to their flexible structure, PVC waterstop tapes adapt to such movements and maintain water tightness. They also offer solutions suitable for different application areas thanks to their different types and sizes.
When applied correctly, it minimizes damage caused by water, reducing the maintenance costs of structures. These tapes can be used not only in new constructions but also to reinforce the waterproofing of existing structures. PVC waterstop tapes are an indispensable building material, especially in areas where water is concentrated.
How to Apply PVC Waterstop Tape?
PVC waterstop tapes are an important material used in construction projects to prevent water leaks. Proper application ensures that the structure is long-lasting and watertight.
Application Steps of PVC Waterstop Tapes:
- Surface Preparation: Before starting PVC waterstop tape application, make sure that the surface is clean, dry and smooth. Dust, dirt, oil or other residues on the surface should be removed. If necessary, roughness should be removed by sanding the surface.
- Cutting and Placing the Tape: Tapes should be cut to the appropriate size for the area to be applied. During the cutting of the tape, details such as corners and joints should be taken into consideration. Before adhering to the surface, it should be checked by placing it dry.
- Bonding Process: The waterstop tape is adhered to the surface using a suitable adhesive or gauge. During the bonding process, it must be ensured that the tape adheres firmly and without air bubbles. The ends and joints of the tape should be glued with special care.
