※  Application

• Foundations: Effective in providing a waterproof barrier for building foundations, protecting structures from groundwater infiltration.

• Roofing Systems: Suitable for flat and sloped roofs, the membrane offers reliable waterproofing and resistance to wear and tear.

• Underground Structures: Ideal for use in basements, tunnels, and other below-grade construction to prevent water seepage and dampness.

• Bridges and Decks: Provides robust waterproofing for bridges, parking decks, and other infrastructure exposed to water and heavy loads.

• Bathrooms and Wet Rooms: Can be used in bathrooms, kitchens, and other interior spaces that require waterproofing.

※  Material Features

• Double-sided Sand Finish: The membrane is coated on both sides with sand, increasing surface roughness and improving adhesion when used with waterproof coatings or adhesives.

• Polymer Modification: The addition of polymers to the asphalt improves flexibility, elasticity, and resistance to aging, ensuring the membrane remains effective in a variety of climates and conditions.

• Waterproof and Moisture-proof: The membrane forms a seamless barrier against water and moisture, preventing leakage and protecting structural integrity in areas prone to dampness.

• Temperature Resistance: Suitable for high and low temperature environments, the membrane maintains flexibility in cold weather and does not soften excessively in heat.

• Tear and Puncture Resistance: The polymer-modified asphalt provides excellent tear resistance, ensuring that the membrane can withstand mechanical stresses during installation and in service.

• Environmentally Friendly: Free of harmful chemicals, the membrane is manufactured with eco-friendly materials, making it safe for both the environment and installers.

※ Advantages

1. Long-lasting Durability: The polymer modification extends the lifespan of the membrane, offering reliable waterproofing for years without deterioration.

2. Superior Adhesion: The double-sided sand finish ensures better adhesion to a variety of surfaces, making installation faster and more secure.

3. Versatile Application: Suitable for a wide range of construction projects, the membrane can be installed in diverse environments, from underground structures to roofing systems.

4. Cost-effective: Its durability and resistance to environmental stresses minimize the need for frequent repairs, reducing long-term maintenance costs.

   
   

※ Installation Guidelines

1. Surface Preparation: Clean the application surface to remove dust, debris, and loose materials. Ensure the surface is dry and smooth before installation.

2. Primer Application: Apply a suitable primer to enhance adhesion between the membrane and the substrate, particularly in areas where adhesion is critical.

3. Membrane Installation: Unroll the membrane and apply it to the surface. Overlap adjacent sheets by at least 10 cm to ensure a watertight seal. Use a roller to press the membrane firmly into place, ensuring even contact with the substrate.

4. Heat Sealing (if applicable): For enhanced sealing, use a torch to lightly heat the edges of the membrane, ensuring full bonding between layers.

5. Protection Layer: In areas exposed to mechanical damage, apply a protection layer, such as a concrete screed or insulation board, to safeguard the membrane from punctures and tears.

※ Maintenance

• Regular inspections of the membrane are recommended, particularly in high-traffic areas or locations exposed to extreme weather conditions. Any damage or wear should be repaired promptly to maintain waterproofing integrity.

※ Storage and Transportation

Proper storage and transportation are crucial to maintaining the quality and performance of the Double-sided Sand Polymer Modified Asphalt Waterproofing Membrane. The following guidelines should be followed to ensure the product remains effective.

1. Storage Conditions

• Temperature: Store the membrane in a cool, dry place, ideally between 5°C and 35°C (41°F to 95°F). Avoid prolonged exposure to direct sunlight, high temperatures, or freezing conditions to prevent material degradation.

• Humidity Protection: Ensure the storage area is well-ventilated and free from moisture. Excess humidity can affect the adhesive properties of the membrane.

• Stacking Requirements: The rolls should be stacked vertically in an organized manner, with no more than five rolls stacked on top of each other to avoid compression damage.

• Sealed Storage: Reseal any unused rolls to prevent exposure to air and moisture, which could affect the product’s performance.

2. Shelf Life

• The typical shelf life of the Double-sided Sand Polymer Modified Asphalt Waterproofing Membrane is 12 to 24 months when stored under proper conditions. Always check the manufacturing date and expiration date on the packaging before use.

3. Transportation Guidelines

• Transport Vehicle: Use dry, clean vehicles for transportation. Ensure that the membrane does not come into contact with harmful chemicals or corrosive substances during transport. Covered or enclosed vehicles are recommended to protect the membrane from rain, sunlight, and excessive heat.

• Prevent Compression and Impact: Secure the rolls properly to prevent movement, collision, or compression during transit, which could cause deformation or damage to the membrane.

• Temperature Control: Avoid extreme temperature exposure during transportation, especially in very hot or cold conditions. Transporting the product in a moderate climate will ensure its integrity.

4. Safety Precautions

• Personal Protective Equipment (PPE): Personnel involved in handling and transporting the membrane should wear appropriate PPE, such as gloves and safety boots, to avoid injury from the rough surface of the membrane.

• Handling Leaks or Damage: If the membrane is damaged or leaks during storage or transport, clean up and dispose of the affected material according to local regulations to avoid environmental harm.

5. Disposal

• Dispose of any unused or damaged membrane materials in accordance with local environmental regulations. Do not burn or dispose of the membrane in a manner that could harm the environment.
