TPE Waterproofing Joint & Corner Sealing Tape

TPE-Based Waterproofing Joint & Chamfer Tape

Chamfer tape (sealing tape) is a specialized material that plays a critical role in waterproofing applications to protect structures against water damage. It is utilized in areas with a high risk of water exposure, such as foundations, balconies, roofs, and terraces. Chamfer tape prevents water leaks by bridging movement joints and corners where structural cracks are most likely to occur. By doing so, it extends the service life of the building and prevents internal issues such as dampness and mold.

Providing flexibility and durability, chamfer tape ensures long-lasting protection. Its high resistance to harsh weather conditions effectively shields structures from external environmental factors. Furthermore, its easy application and excellent adhesion properties accelerate the installation process while offering reliable, continuous insulation. Utilizing chamfer tape in construction projects reduces long-term maintenance costs, enhances the structural integrity, and provides an environmentally resilient solution, making it an indispensable component in modern construction.

ADVANTAGES

• Features high continuous elasticity, accommodating structural movements effortlessly.
• Quick and highly practical to install.
• Offers excellent resistance to a wide range of chemical substances.
• Highly resistant to extreme weather conditions, UV radiation, mechanical impacts, and bending.
• Easily cut and jointed; provides seamless integration into all types of waterproofing systems through its reinforced mesh edges.
• Ensures reliable mechanical anchoring and maximum bond strength due to its perforated polyester lateral fabric.
• Maintains flexibility over time, resisting tearing and deformation across dynamic cold joints.

APPLICATION AREAS (RECOMMENDED USES)

• Wall-to-floor junctions and chamfers in wet areas (bathrooms, kitchens, showers).
• Water-retaining structures, including ponds, water tanks, and wastewater treatment plants.
• Bridging and sealing cold joints and dynamic cracks in concrete slabs and retaining walls.
• Balconies, roof edges, parapet walls, and terraces.

HOW TO APPLY WATERPROOFING CHAMFER TAPE? (APPLICATION STEPS)

Chamfer tape is vital for waterproofing corners and joints. Proper application significantly extends the structure's durability and water resistance. Below is the step-by-step application process:

Required Materials:

• Cleaning equipment (brush, vacuum, or cloth).
• Repair Mortar (for patching damaged surfaces).
• Liquid-Applied Waterproofing material.
• Chamfer Tape (pre-cut to the required dimensions).
• Roller or brush for coating application.

1. Surface Preparation:

Proper surface preparation is crucial. The substrate must be completely clean, dry, sound, and smooth. All dust, paint, dirt, oil, detergent residues, and any loose or unsound concrete must be eliminated. Any existing voids, honeycombs, or cracks must be repaired at least 24 hours prior using an appropriate structural repair mortar.

2. Cutting the Chamfer Tape:

Measure and cut the tape to match the specific dimensions of the joint or corner. Carefully prepare the lengths to fit intersection points precisely, ensuring no unnecessary overlaps or shortfalls occur.

3. First Coat Waterproofing Application:

Apply a generous, even layer of the chosen liquid-applied waterproofing material along the corner or joint where the tape will be placed. This wet layer acts as the bedding adhesive for the tape.

4. Placement of the Chamfer Tape:

While the first coat is still wet, immediately position the chamfer tape over the corner or joint. Press the fabric edges firmly into the wet waterproofing layer using a trowel or stiff brush, ensuring the tape is fully embedded and perfectly conforms to the substrate without any trapped air bubbles or creases.

5. Second Coat Waterproofing Application:

Allow the first coat to cure according to the specific technical guidelines of the waterproofing product used. Once fully cured, apply the second layer of the liquid-applied waterproofing directly over the entire tape assembly. This encapsulates the tape, fully reinforcing the watertight seal.

6. Final Inspection:

After the system has fully cured, inspect the applied areas. Correct any uneven spots to ensure a seamless, homogeneous, and heavily protected waterproof finish.

POINTS TO CONSIDER DURING APPLICATION

• Do not apply in excessively high-temperature environments or on surfaces exposed to intense, direct sunlight and strong winds.
• The DRYFIX Chamfer Tape must strictly be embedded into the waterproofing layers while the material is still wet.
• The tape's fabric edges must be entirely overcoated and concealed by the subsequent waterproofing layers.
• Protect freshly treated surfaces from rain, frost, and mechanical damage for at least 24 hours.

HEALTH, SAFETY, AND ENVIRONMENTAL WARNINGS

• Appropriate Personal Protective Equipment (PPE) should be worn during application.
• Always refer to the product's Safety Data Sheet (SDS) and technical instructions before use.
• Keep out of the reach of children.
• Keep away from open flames and sources of ignition.

PACKAGING & STORAGE

• Packaging: Supplied in 50-meter rolls.
• Storage & Shelf Life: Can be stored for up to 5 years from the production date in its unopened, original packaging. Store in a cool, dry place, strictly protected from frost. Do not stack pallets on top of each other for long-term storage.
