Introduction:
Dadco Polyester DPA-180 is a waterproofing APP MODIFIED bitumen, reinforced with a high quality non-woven polyester mat.
Description:
Dadco Polyester DPA-180 waterproofing membranes are manufactured from a high performance membrane produced with APP MODIFIED bitumen compound, then coated onto a dimensionally stable Polyester mat of 180 g/m² reinforcement, and the surface from both sides of a thermo fusible plastic film.
Characteristics:
- Excellent bonding to surfaces.
- Easy to apply.
- Excellent resistance to salts and water-prone chemicals.
- Accommodates structural movements.
- Stability at high temperatures.
- 10 year warranty for the product.
Uses:
Dadco Polyester DPA-180 membrane is ideal for a wide range of waterproofing applications such as roofs, basements, tunnels, car parks, wet areas (kitchens & bathrooms).
Application Tools Required:

Application:
Concrete surface should cleaned thoroughly of all of contaminates 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 rolls should be aligned correctly with an overlap of 10 cm at least from both sides. Using the gas torch, bond the sides of the roll by heating the overlaps.
General Data:
- Roll length: 10 meters
- Roll width: 1 meter
- Roll thickness:4 mm
- Reinforcement: Polyester
Backing and Storage:
Dadco Polyester DPA-180 is produced in rolls of 1 × 10 meters. Special lengths are available upon request. The rolls are palletized and shrink-wrapped. The rolls are kept vertically, and pallets should not be stacked on top of each other.
