When building underground structures, such as basements, tunnels, or reservoirs, one of the main challenges is preventing water seepage that could damage the construction. Well, this is where waterstop plays an important role! Waterstop for underground buildings may look simple, but its function is extraordinary in maintaining the integrity of the building.
But, did you know that waterstop has various types with their own functions and advantages? Many people don’t know it yet, you know. So let’s find out more about the types of waterstop that can be the right solution for your underground construction project!
Types of Waterstop for Underground Buildings
Waterstop comes in various materials designed to deal with different construction conditions. Each type has its own uniqueness and advantages. To keep your underground building seepage-free and sturdy, it’s important to choose the right waterstop. Here are some of the types.
1. PVC (Polyvinyl Chloride) Waterstop
PVC waterstop is one of the favorite choices in underground building projects. This material is known to withstand various weather conditions and has exceptional elasticity.
Typically, PVC is used for expansion joints, construction joints, and motion joints in concrete. Besides being resistant to chemicals, it is also easy to install, even in areas with complex geometries. Its flexibility is really a plus! Examples of PVC waterstop products from Estop are the Estopper CJ/ EJ series with widths of 150, 200, and 250 mm.
But, be careful when installing. If the installation is not neat, the function of this waterstop can be reduced. So, make sure everything is installed correctly for maximum results.
2. Bentonite Waterstop
Having a unique property that can expand when exposed to water, bentonite waterstop is suitable for concrete construction joints. Once in contact with water, bentonite will expand and automatically fill the gap, making water unable to seep through.
What are the advantages of this waterstop for underground buildings? Bentonite can seal small cracks and the price is also quite pocket-friendly. But remember, bentonite is more effective for still water conditions. If the water pressure is too high, its performance can be reduced.
3. Rubber Waterstop
Rubber waterstops are made of elastomeric material that is super flexible and durable. This type is ideal for buildings that experience frequent structural movement, such as bridges or tunnels.
Its advantages? It is resistant to high pressure and suitable for large projects with high technical requirements. However, installation requires specialized skills and initial costs tend to be higher than other types.
4. Metal Waterstop
Made from materials such as copper, stainless steel, or aluminum, metal waterstops are known for their exceptional durability. This type of waterstop for underground buildings is often used for projects that require extra protection against large mechanical stresses.
Although super strong, these metals lack flexibility, so careful planning is required before installation. In addition, the initial cost and maintenance are also quite expensive.
5. Hydrophilic Waterstop
Hydrophilic waterstop is similar to bentonite in that it expands when exposed to water. The difference is that this type is made of synthetic materials such as polyurethane or other polymers.
Its main advantage is its strong adhesion, even on rough concrete surfaces. Apart from being durable, this waterstop is also easy to install. However, there is one thing that must be considered, which is to make sure that the installation area is dry so that this material does not activate prematurely. Examples of hydrophilic waterstop products from Estop Estopper Hydrophilic S10 and S20.
Advantages of Using the Right Waterstop
Using the right waterstop is important! Not only to prevent leaks, but also underground buildings will last longer and have less risk of damage. If the type of waterstop is appropriate, the quality of construction will be maintained, so you don’t have to deal with problems in the future. Simple but very influential, right?
Those are some types of waterstop for underground buildings. Although it looks simple, with the right waterstop, your underground building will be more durable and problem-free.
