The selection of the water bars shall be made based on the nature of the construction and its applicability. All the types waterstops cannot be used in every concrete structure.

Waterstops are not used along within structures. They need to be connected with the other waterproofing systems. The following occasions can be identified as locations where we use waterstops.

In addition, different types of waterstops are not used in the same structure due to their compatibility. For example, it is very difficult to lay the steel water bare with PVC water bars.

Mostly in the following structures water stops are used.

• Basement walls
• Basement slabs, raft foundation when used as the basement floor.
• Subway and Tunnels
• Canals
• Spillway walls and ogee
• Other liquid retaining structures

Commonly, water stops are placed at the construction joints, contraction joints, movement joints, and expansion joints. If there are water tightness requirements, the only option to avoid it is the water stop.

Let’s discuss different types of water stops.

• PVC waterstops
• Rubber waterstops
• Metalic waterstops
• Bentonite waterstops
• Hydrophilic waterstops
• PVC Waterstops
• PVC waterstops are widely used construction. They are very easy to use and handle at the site and also the cost also comparatively reasonable.

PVC waterstop is used for the movement joints and expansion joints due to its ability to bear the movement of the structures.

Rubber waterstops are major components in projects involving concrete construction that call for waterproofing techniques. They are made to stop liquid from entering or leaving expansion joints and concrete joints, preventing water from leaking through and damaging the structure.

SBR (styrene butadiene rubber), neoprene rubber, and natural rubber are just a few of the rubber materials that can be used on creating this rubber product. Each of these rubber varieties has distinct physical characteristics that make it excellent for particular purposes. While neoprene is more suited to industrial and chemical applications due to their greater resistance to chemicals and harsh temperatures, SBR are more affordable and suitable for non-moving structures.

During the construction stage, rubber waterstops are commonly cast into concrete joints. They are built to withstand intense physical pressure and stress, including tremors and vibrations brought on by alterations in the environment like temperature fluctuations or earthquakes.

They are frequently used in dams, reservoirs, and other structures that contain or exclude water. They are also utilized in places where waterproofing is essential, such as sewage treatment facilities, swimming pools, and underground constructions.

This must be installed according to the manufacturer's installation instructions and with the use of high-quality supplies to guarantee their efficiency. Regular checks should also be done to look for any evidence of wear or damage that could affect its functionality.

Various Applications:

Rubber water stoppers are adjustable and efficient components for preventing erosion and water damage in a wide range of construction applications.

• One common application is in valley-dammed reservoirs, where air-inflated rubber stoppers are put into the spillway to form a watertight closure. By doing this, water cannot run over the top of the dam and erode the land around. Rubber water stoppers are also useful for keeping animals and dirt out of water reservoirs.

• Rubber water stoppers can be used as retaining walls to prevent water erosion. The rubber water stopper is a robust and solid barrier that can hold a lot of soil since it is constructed of thick rubber stretched over two metal frames and filled with dirt or rocks.

• Rubber water stoppers are also very important in a home's drainage system. A typical drainage system called a French drain collects rainwater from the roof and the ground and directs it away from the home. Without adequate drainage, water can collect around the foundation and result in significant damage, including issues with mold and mildew. A rubber water stopper that ensures adequate water evacuation and prevents damage to the foundation and frame can be fitted at the end of the French drainpipe to avoid this.

Rubber waterstop is used to efficiently seal the joints while constructing culverts encased within boxes or conduits. It reduces water seepage and increases the culvert structure's overall durability.

Building a Cut-and-Cover Tunnel

Rubber waterstop is a reliable sealing option in the building of cut-and-cover tunnels, where parts are created and subsequently covered. It ensures the tunnel joints' tightness, preventing water penetration.

Subterranean Structures

Rubber waterstop is used in subterranean buildings such as basements, foundations, and underground parking garages. It effectively seals joints and keeps water out of these crucial locations.

Concrete Ranging from New to Old

Rubber waterstop is appropriate for use with both newly poured concrete and existing constructions. It can be used to reinforce joints and provide waterproofing during new construction or retrofitting applications.

Pipe Piercings

Rubber waterstop is used when pipes are installed through concrete structures. It produces a secure and waterproof seal around the pipe, preventing leaks and preserving the structure's integrity.

Advantages:

Non-toxic and Safe for the Environment

Rubber waterstop is a non-toxic material that may be used in a variety of building projects without harming the environment or human health.

Up to 200% Expansion Rate

Rubber waterstop's rapid expansion rate allows it to accommodate substantial movements and deformations in concrete buildings, maintaining a secure and long-lasting seal.

Rubber waterstop may be smoothly implemented into projects of different complexity thanks to easy instructions and compatibility with normal construction practises.

Effective Even in Salty Circumstances

Even in saline or high-chloride situations, rubber waterstop remains effective. It is resistant to the corrosive effects of saltwater, making it ideal for use in coastal environments, maritime constructions, or projects involving the storage or transfer of saline liquids.

Installation of Rubber Waterstop

Rubber waterstops are an important element in guaranteeing successful water leakage prevention in concrete structures. It is necessary for the concrete surface to be clean, dry, and debris-free in order to install it efficiently. Using adhesive or mechanical fasteners, it should be positioned around the joint or edge where water leakage is anticipated.

This is normally put before the concrete is poured in cast-in-place constructions, but it can also be inserted after the joint has been saw-cut in existing concrete structures. To get the desired length and shape, it may occasionally need to be welded.

It is critical to ensure that it is properly fixed to avoid water leakage, which can cause structural damage, mold growth, and other problems. It must be firmly fixed in place and must not have any gaps between it and the concrete surface in order to be installed properly.

Overall, rubber waterstops must be installed correctly to ensure the strength and endurance of concrete structures, and this task should only be carried out by qualified experts.The video below will help give you some knowledge on how to install rubber waterstopper.
