Rubber Waterstop

Updated: Jun 15, 2023

Matlex - Rubber Waterstop

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.

Features and Benefits:

Excellent Elasticity and Flexibility

Rubber waterstop has a high elasticity and flexibility, which allows it to adapt motions and vibrations in concrete buildings. It can endure expansion, contraction, and settling with ease, ensuring long-term durability.

Resistant to Abrasion and Tearing

Rubber waterstop has a strong composition that makes it resistant to abrasion and tearing. It can survive extreme circumstances, preventing damage or degeneration even in high-stress situations.

Resistant to Corrosion and Chemicals

Rubber waterstop is very resistant to chemical corrosion, preserving structural integrity. It functions as a protective barrier, preventing the harmful effects of aggressive compounds typically present in construction situations.

Resistant to Water

Rubber waterstop, as the name implies, is specifically designed to resist water infiltration. It produces a waterproof seal, avoiding leaks and ensuring joint and penetration structural integrity.

Resistant to Weather and Aging

Rubber waterstop is designed to withstand extreme weather conditions such as high temperatures, UV radiation, and atmospheric contaminants. It is also resistant to ageing, retaining its sealing characteristics for an extended length of time.

Excellent Sealing Effect

Rubber waterstop excels at delivering a good sealing effect, sealing joints and penetrations to keep water, moisture, and other undesired substances out of structures. This increases the durability and dependability of construction projects.


Construction Joints that are Poured in Place

Rubber waterstop is commonly used in poured-in-place construction joints such as floor slabs, walls, and basements. It provides a safe and waterproof link between various concrete components.

Culverts in Boxes

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.


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.

Simple to Use

Rubber waterstop is intended for simple installation and use. Its adaptability enables for simple handling and application, making it useful for construction professionals. 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.
