DADCO FIBER DF-105 – Fast International Petrochemicals Co.Ltd.

Dadco Fiber-105


Dadco Fiber-105 is an oxidized bitumen membrane with glass fiber reinforcement.


Dadco Fiber-105 waterproofing membranes is manufactured from high performance membrane produced with a modified bitumen compound, then coated onto a dimensionally stable glass fiber matt of 105 g/m² reinforcement. The surface from both sides has a thermo fusible plastic film.


  • Excellent bonding to surfaces.
  • Easy to apply.
  • Excellent resistance to salts and water-prone chemicals.
  • Accommodates structural movements.  
  • Stability at high temperatures.


Dadco Fiber-105 membrane is ideal for a wide range of waterproofing applications such as: Roofs, basements, tunnels, car parks, wet areas (kitchens & bathrooms).

Application Tools Required:

Measuring tape, marking string, gloves, goggles, gas torch, knife, trowels.


Concrete surfaces should cleaned thoroughly of all of contaminants like dust, traces and oils, then apply Dadco Primer D-41 on the surface by brush or roller and allow it to dry to promote the adhesion between the membrane and surface.

The membrane rolls should be aligned correctly with an overlap of 10 cm at least from both sides. Using a gas torch, bond the sides of the roll by heating the overlap enough to obtain a high and excellent waterproofed surface.

General Data:

  • Roll length: 10 meters
  • Roll width: 1 meter
  • Roll thickness:4 mm


  • Fiber glass

Backing and Storage:

DADCO FIBER 105 is produced in rolls of 1 × 10 meters. Special lengths are available upon request. The rolls are palletizes and shrink-wrapped. The rolls are kept vertically, and pallets should not be stacked on top of each other.

Health and Safety:

All safety measures should be taken during the application. Fire extinguishers should be available at the site. Workers should wear protective clothing during the application.
