HyDrain 456 – Prefabricated Sheet Drain

A prefabricated sheet drain that is constructed using a high strength, high flow capacity, formed polystyrene drainage core with a nonwoven filter fabric bonded to one side. The filter fabric is securely bonded to each dimple and prevents soil intrusion into the flow channel while allowing water to freely enter the drain core from one side.

Product Highlights

  1. Offer a compressive strength and flow capacity that is significantly higher than geonet products.
  2. Constructed using an AASHTO M 288-06 Class 2 filter fabric.
  3. Manufactured with recycled materials
  4. HyDrain 456 products are environmentally friendly and can contribute toward LEED design credits
  5. Ideal for heavy commercial and residential applications
  6. Functions as a protection course
  7. Woven filter fabrics are better suited to receive concrete pours and provide excellent filtration for the organic soils used in planter applications. Help effectively manage site issues
  8. Designed to withstand the additional stress demands associated with horizontal applications

Installation

  • Limit unpackaged material UV exposure to a cumulative maximum of 14 days during installation.
  • Do not install materials during high wind events.
  • Do not install materials when ambient temperatures are below 20 degrees Fahrenheit or above 100 degrees Fahrenheit.
  • Do not expose materials to chemicals that are strong acids, strong bases, or high in solvents content
  • Protect materials from site construction damage, flames, and other environmental conditions that may damage the materials.
