Danosa Polydan 180-60/GP Elast | 1m x 8m Black Mineral

High-performance SBS elastomeric 5,6 kg/m² capping sheet. Torch applied roofing felt. Used with Danosa Esterdan 30/P Elast and Recticel Powerdeck U Insulation Boards.

Overview: 

The Danosa Polydan 180-60/GP Elast. is a high-performance bituminous SBS-modified cap sheet, reinforced with heavy non-woven polyester felt. The upper surface is finished with mineral chipping, and the underside is equipped with a quick-melt thermofusible film. This product is designed for torch-applied applications and Safe2Torch details using hot air.

Applications:

• Basement Wall Waterproofing - Effective waterproofing solution for protecting basement walls.
• Two-Layer Membrane Capsheet - Ideal for waterproofing boards with mineral self-protection.
• Carpark Areas - Suitable for waterproofing systems in parking roofs and rolling surfaces, allowing for direct application of agglomerate on the membrane.
• Multi-Layer Waterproofing Systems - Functions as a reliable capsheet in multi-layer waterproofing systems.
• Single-Layer Waterproofing Systems - Can be used as a standalone waterproofing membrane.

This product is an excellent choice for robust and long-lasting waterproofing solutions in various applications, ensuring high performance and durability.

Important details about this product:

• Length: 8m
• Width: 1m
• Thickness: 3.9mm (Overlap)
• Surface Area: 8m²
• Weight: 5.6kg/m²

Advantages & Benefits

• High Movement Capability – Accommodates structural movements without compromising integrity.
• Enhanced Mechanical Performance – The higher grammage of the polyester reinforcement provides superior tensile strength and resistance to both static and dynamic piercing.
• Versatility – Suitable for waterproofing buried structures such as basement walls, as well as structures subject to vehicular traffic, including road and railway decks and carpark roofs.
• High Tensile Strength & Elongation – Offers robust tensile strength and significant elongation at break, ensuring durability and flexibility.
• Resistance to Piercing – Exhibits high resistance to both static and dynamic piercing, protecting against mechanical damage.
• Rot-Proof – Resistant to biological degradation, ensuring longevity.
• Long-Term Stability – Maintains performance and integrity over time.
• Mechanical Damage Protection – Provides excellent protection against piercing from occasional pedestrian traffic, typical on flat roofs.

Application Specifics

• The membrane should not be installed in adverse weather conditions. It must not be laid in rain, snow, or heavy fog, nor if the temperature falls below 5°C, unless precautions against condensation have been taken.
• Do not apply on wet or frozen surfaces.
• At falls in excess of 5° (1:11), precautions against slippage should be allowed and mechanical fixing should be installed.
• The membrane layers must always be installed with staggered overlaps and in such a manner that the laps fall in the direction toward the outlets.
• Attachment of reinforced bituminous membrane roofing may be achieved by full bonding, by partial bonding, or loose laid (ballasted) with guidance from Danosa technical services; the choice should depend upon the type of substrate and the required resistance to wind uplift pressure.

For single layer application direct to deck:

• Deck surfaces must be dry, clean, and free from sharp projections such as nail heads and concrete nibs.
• When torching Polydan directly to a suitable substrate, the substrate should be prepared using a primer; either bitumen primer HM, Curidan, Maxdan or Maxdan caucho at the recommended rate prior to installation of the waterproofing system.
• Fully bonded torch-applied membranes should only be used with non-combustible substrates.

• For field applications:

1. Roll the membrane into position, allowing for 80mm side overlaps and 100mm head overlaps, and cut to length. All overlaps and cross joints should be staggered by a minimum of 300mm.
2. Using a length of 100mm pipe (cut fractionally short of roll width) as an insert tube, roll back the membrane for a portion of the length (approximately 50%).
3. Heat activate the membrane by torching in a vee area between the roll and substrate.
4. The roll can be pushed forward by foot or by other suitable equipment. Apply downwards pressure when moving the roll to extrude a molten bead of bitumen from edges.

• For detail applications:

1. Place the membrane into position, allowing for 80mm side overlaps and 100mm head overlaps, and cut to length, ensuring all overlaps and cross joints are staggered by a minimum of 300mm.
2. Heat activate the membrane by torching between the membrane and substrate.
3. Apply pressure and consolidate the bond to the substrate, ensuring a molten bead of bitumen is extruded from the edges.

For system application including underlay:

• Fully bonded torch-applied membranes should be installed over non-combustible underlays.
• It is possible to install a torch-receivable underlay into hot bitumen and then torch-apply a capping sheet which should be specifically designed for torching, such as Polydan. Bonding is achieved by melting the lower surface by torching and pressing the membrane down. Care must be taken not to overheat the membrane.
• For field applications:

1. The capsheet should be laid along the same direction as the underlay membrane, offset by a minimum of 300mm to ensure sufficient staggering of laps between layers.
2. Roll the membrane into position, allowing for 80mm side overlaps, and 100mm head overlaps and cut to length. All overlaps and cross joints should be staggered by a minimum of 300mm.
3. Using a length of 100mm pipe (cut fractionally short of roll width) as an insert tube, roll back the membrane for a portion of the length (approximately 50%).
4. Heat activate the membrane by torching in a vee area between the roll and substrate.
5. Roll can be pushed forward by foot or by other suitable equipment. Apply downwards pressure when moving the roll to extrude a molten bead of bitumen from edges.
