What is a Joint Filler?

A waterproof crack or joint filler is a chemical compound that helps seal the gap between two identical structures or sections of the same structure. When it comes to the waterproofing property of Joint and Crack Filling Adhesive, it is important to consider the specific product being used. Many joints and crack-filling adhesives are indeed waterproof and provide an effective barrier against water penetration. These adhesives are formulated to withstand environmental conditions, including exposure to water, ensuring a durable and long-lasting seal.

Grouting is one of the most common application scenarios of joint fillers. This is where the joint sealer fills the gaps between tiles. This application is common in kitchens, vestibules, terraces, bathrooms, balconies, and pools. The joint filling is also useful when sealing the gaps left after filling the spaces in bricks or masonry stones and leveling the upper section with a trowel.

Another common application for joint fillers is sealing concrete cracks that appear as time passes. As concrete grows old and is subjected to various impacts and harsh climatic conditions, it could have noticeable openings. A crack filler can help ensure these openings don’t grow or damage the concrete. It firmly sinks in between the two concrete sections and helps to hold them together while appearing as if it is plaster or cement-based.

What are the Benefits of Waterproof Joint Filling?

Joint cuts and cracks should be filled as soon as they appear. Below are the major benefits of doing so:

  • Increased durability. Unlike polyurethanes, which can degrade over time due to exposure to environmental conditions, this adhesive is specifically formulated to withstand even the harshest elements. It maintains its strength and effectiveness, providing long-lasting protection against water leakage.
  • Enhanced stability. Joint sealing effectively seals even the deepest and widest cracks. This means that it can effectively prevent the root of cracks from expanding, which can lead to further damage. This adhesive is also moisture insensitive, allowing it to maintain its strong adhesion in various moisture conditions.
  • Improved appearance. Its seamless finish creates a smooth and uniform surface, enhancing the overall appeal of the structure. This is especially important for areas such as basement floors and concrete water structures, where appearance is a crucial factor.

Waterproof Joint Filler Types

There are different types of materials used to seal concrete cracks, but the most common are:

Silicone Joint Filling Material

Silicone joint filler has numerous uses since it can be applied to different wet surfaces, such as marble, granite, tiles, and ceramic. Its application also suits both indoor and outdoor areas. This cement-based joint sealant has an additional polymer binder and a water-repellent silicone structure, making it incredibly durable.

Silicone joint filling material can fill spaces as wide as eight millimeters while leaving a smooth, level surface. It has a low water absorbency potential, making it fully waterproof in whatever way it is applied.

Epoxy Joint Filling Material

As one of the most popular crack-filling materials, epoxy joint sealant can cover spaces spanning 2–15 millimeters. It is applied and cleaned very easily. This material contains no solvents, is chemical-resistant, and has immense strength.

Epoxy joint sealant material also has a diverse application base, from interior to exterior surfaces, such as tiles, glass mosaics, and porcelain ceramics. It is perfect for kitchens, dining halls, and spas with areas such as sauna and swimming pools.
