Product Description

bitumen adhesive tape/waterproof materials/ building materials

Self Adhesive Waterproof Membrane- Popular USA

Bitumen Adhesive Tape/Waterproof Materials/ Building Materials


Hongyuan Waterproof has newly developed RAM-CL, the self-adhesive membrane made from cross laminating HDPE film, asphalt and high polymer adhesive. This product is featured by high property performance, cold application, excellent size stability, anti-UV and good tear resistance.

HDPE film used in this product is manufactured through cross-lamination processing, which enables the film elongation stable both in MD and TD, while no deformation is caused. The polymer (chain) and cement polymer (silicate) function together to form cross interface structure and ensure a permanent, continous seal on cement base.



Product Mechanism

Hongyuan crossing-laminated HDPE filme is made by special formula. It overcomes shortcomings of ordinary film and have high tensile strength, solar stable and no bubbles.


Besides, the longitudinal tensile strength of ordinary HDPE film is larger than its transverse tensile strength. While the longitudinal and transverse value of Hongyuan RAM-CL is equal, which enables the sheet has stronger adhesion on fasteners than ordinary membrane.

An ordinary HDPE film is single directional stretching film, waterproof membrane with this film is easily wrinkled when temperature change, even broken if heavy deformation.



Excellent physical property


  1. Superior shank tear strength and watertightness in scres fixed position
  2. Better adhesion on screws and fasteners than ordinary membrane, stronger tear resistance in both direction.
  3. Good tensile strength and weatherability
  4. Size stable and no crease, a reliable safeguard for waterproof


Friendly construction performance


  1. Firm bonding performance between membrane and base. If any damage on membrane sheet, the leaking water is confined in certain area without channeling. Leakage point is same with broken point, convenient for examining and repaire. Its unique "self-healing" function ensures pin-holes self-healing.
  2. Good adaptability to construction environment. It can be applied on wet base without use of primer, solvents or fire, which guarantees construction period and avoids environment pollution.
  3. Apple green facial film eliminates light pollution compared to silver white surface.
  4. Adaptability to weather change from hot area to cold district, good adhesion in special-shaped part with no empty hollowing.



  1. RAM-CL membrane is recommended to apply in non-exposed roofs, underground waterproof projects, subways, tunnels and water channels. It is specially used in such constructions that no open fire is allowed to used.
  2. Cement mortar is used to install RAM-CL onto base, while self-adhesive is recommended to use between membrane sheets.
