Water Insulation in Tunnel Project: Combination of Injection and Membrane, offers a highly effective solution for waterproofing tunnel construction. When these two methods are used together, the longevity of the structures is ensured. Groundwater poses a serious threat in tunnel excavations, but this risk is reduced with the right insulation systems.

How Does the Injection System Work?

The injection method is applied by applying special chemicals to the cavities in the structure under pressure. These chemicals enter the cracks and stop the progress of water. This system provides a quick solution to water leaks that may occur in the tunnel. At the same time, Sempoly The high-performance injection products developed by provide long-term durability. However, injection alone is not enough.

Advantages of Membrane Systems

Membranes are special coatings that completely cover the surfaces. Thanks to these coatings, water cannot reach the tunnel structure. Sempoly Water Insulation Products PVC and bituminous membranes offer excellent performance despite difficult site conditions. In addition, these products can be applied quickly and are low cost. However, careful surface preparation is required during application.

Why Are the Two Systems Used Together?

When injection and membrane systems are used together, a complementary protection layer is created. While the membrane serves as the main protection function, the injection system immediately stops any possible leaks. This unity, in tunnel construction It provides a reliable solution to all water problems encountered. However, integrating the systems requires expertise. For this reason, expert consultancy It is recommended to take advantage of the services.

What Should Be Considered During the Application Stages?

Before the application starts, a detailed ground survey should be carried out. During this study, the water level and soil structure should be examined. Then, the membranes should be carefully fixed to the surface. However, the connection points should definitely be sealed. In the next stage, the cracks should be filled with injection. Sempoly experts provides field application support for these transactions.

Maintenance is Required for Long-Lasting Insulation

Insulation systems are exposed to external factors over time. Therefore, they should be checked at regular intervals. Particularly, the connection points of the membranes are prone to cracking. These areas should be observed regularly. Professional care services prevents such problems. In addition, the proper operation of water drainage systems directly affects insulation performance. If these systems become clogged, water accumulation becomes inevitable.

The Role of Sempoly in Waterproofing

For tunnel projects Specially developed Sempoly solutions offer an integrated structure with both injection and membrane systems. In addition, the company offers technical consultancy and also provides application support. However, each project has its own special needs. Therefore, project-specific solutions must be developed. Sempoly's expert team has extensive experience in this regard.
