Bentonite Waterproof Blanket/Pad
Bentonite Waterproof Blanket/Pad
Update time:2024.10.30

The Bentonite Waterproof Blanket/Pad is a versatile, high-performance geosynthetic product designed for effective waterproofing, sealing, and containment applications in various industries. Composed of a layer of sodium bentonite clay, the blanket/pad is typically encapsulated between geotextile fabrics or coated with a geomembrane to enhance its durability and performance. When hydrated, the bentonite layer swells and forms a self-sealing barrier that effectively blocks water infiltration, making it an ideal solution for projects requiring long-lasting and reliable waterproofing.

Product Features

  • Self-Sealing: The sodium bentonite expands when in contact with water, forming a tight, impermeable barrier that prevents water from penetrating, ensuring effective waterproofing and containment.
  • Waterproofing Performance: The blanket/pad provides exceptional resistance to water infiltration, making it ideal for areas requiring reliable, long-term waterproofing.
  • Chemical Resistance: The material is highly resistant to a wide range of chemicals, oils, and other contaminants, making it suitable for use in diverse environmental conditions.
  • Durability: Encapsulated in a protective fabric or geomembrane, the bentonite waterproof blanket/pad is durable, puncture-resistant, and resistant to UV degradation, ensuring long-term performance in harsh conditions.
  • Easy to Handle: The lightweight nature of the product makes it easy to transport, install, and handle, reducing labor and time costs during construction.
  • Eco-Friendly: Made from non-toxic, natural bentonite clay, the product is environmentally friendly and safe for use in sensitive ecosystems such as fish ponds and agricultural applications.
  • Maintenance-Free: Once installed, the bentonite waterproof blanket/pad requires minimal maintenance, making it a cost-effective solution for waterproofing and containment.
  • Versatile: Suitable for use in both temporary and permanent applications across a wide range of industries, offering flexibility in design and installation.


Product Specifications

  • Color: Typically available in neutral colors such as grey or black, though other colors may be available based on customer specifications.


Applications

  • Landfills: Used as a lining material to prevent leachate from contaminating the surrounding soil and groundwater.
  • Ponds & Reservoirs: Provides waterproofing and ensures water retention in artificial ponds, lakes, and reservoirs, preventing leakage and contamination.
  • Artificial Lakes: Ideal for the construction of ornamental lakes in parks, golf courses, and recreational areas, offering reliable water containment.
  • Water Conservation: Applied in irrigation ponds or agricultural reservoirs to retain water, especially in areas where water conservation is essential.
  • Mining: Used for tailings ponds, leachate containment, and other mining applications, providing safe and effective containment of hazardous materials.
  • Wastewater Treatment: Used in wastewater treatment plants to line ponds and lagoons, preventing contamination of surrounding land and water.
  • Stormwater Management: Effective in stormwater detention basins and retention ponds, ensuring water is contained and runoff is properly managed.
  • Agricultural Applications: Often used for lining farm ponds, reservoirs, or for water storage in agricultural operations, promoting water conservation and reducing seepage.


Construction Recommendations

  1. Site Preparation: Prepare the surface by clearing any sharp objects, debris, and large rocks. The substrate should be smooth and compacted to prevent punctures or damage during installation.
  2. Installation Method: Unroll the Bentonite Waterproof Blanket/Pad over the prepared area, ensuring it lays flat without wrinkles or folds. Ensure the edges are properly aligned and cut to fit the required shape.
  3. Seam Welding: For larger areas, seams can be welded or sealed using heat or adhesive methods to ensure a continuous, impermeable membrane. It is important to ensure the seams are thoroughly tested for leaks.
  4. Edge Treatment: Secure the edges of the blanket/pad by burying them in a trench or using anchors to prevent movement. Proper edge sealing is crucial to prevent water from seeping under the membrane.
  5. Backfilling: Once the blanket/pad is in place, it is recommended to cover it with a layer of soil or geotextile fabric to protect it from UV degradation and mechanical damage.
  6. Inspection and Maintenance: After installation, periodically inspect the blanket/pad for any damage, such as punctures or tears. If any issues are found, they should be immediately addressed using patching or re-welding techniques. Regular inspections will ensure the long-term effectiveness of the waterproofing system.
