Waterstops are used to seal the seams. When any seam begins to deform or loses its tightness, waterproofing dowels are used, which are made of various materials. If you choose the wrong waterstops, this can lead to unpredictable consequences.
This technology was first used in the early 50s. At that time, the seams were sealed with metal waterstops. Prices for waterproofing dowels can be found on the website of the online store. There are many products available, suitable for different types of work.
What types of waterproofing dowels are there?
Products have the following characteristics:
- high resistance to moisture and other non-concentrated solutions;
- structural strength;
- preservation of elasticity with significant temperature changes;
- pressure resistance;
- long service life (equal to the service life of the construction object).
When choosing building materials, it is important to know the types and shapes of dowels in order to make the right choice. Depending on the installation method, 4 types are distinguished:
- Protective. They are used for sealing working joints of concreting. Manufacturers add additional materials that expand when exposed to water, which leads to additional sealing.
- Internal. These keys are used to seal deformed seams. Achieving complete sealing of the joints is possible only by completely filling the voids with insulating material. Such dowels are most often used in the construction of swimming pools, dams and sewage treatment plants.
- Formwork. This type of dowel is used only during the construction of formwork structures. It is easiest to pick them up because they have a certain compatibility with different formwork systems.
- Repair. These keys are used when repairing an expansion joint. These products are the easiest to install because they have an overhead installation method.
Important. Waterproofing dowels differ not only in type and shape, but also depending on the manufacturer. Products from different companies can differ significantly, so it is important to look at the compatibility of building materials.
Tips for choosing waterproofing dowels
The design documentation should contain the recommended material manufacturers. In the absence of these points, you need to immediately discuss this issue with customers.
When choosing dowels, it is always important to remember the following points:
- the supplier's documentation must indicate the manufacturer and materials of manufacture;
- at the time of acceptance of the goods, it is important to obtain certificates of conformity and a product passport certified by the manufacturer;
- savings during construction can always lead to tragic consequences, therefore it is important to select high-quality materials that have all the supporting documents;
- there is a special register of dealers where you can check the compliance of materials and the supplier that provides them;
- you can always get additional advice from professionals engaged in construction work for a long period;
- take into account the length, width, thickness and type of product when choosing.
Important. Manufacturers tend to make different waterstops in length, width, configuration. This approach allows you to select the appropriate dowels, taking into account the peculiarities of the facility being erected or repaired.
The most popular materials for waterstops are PVC and EPDM. Before purchasing waterproofing dowels, it is important to thoroughly inspect the joint in order to find the best solution. In order not to be mistaken with the choice, it is important to study all the features of the keys, and pay special attention to their composition. A properly selected product will increase the overall strength of the structure and protect it from moisture.
