Bituminous SBS modified membrane reinforced with a heavy non-woven polyester felt. Finished in a quick-melt thermofusible film. Designed for torch-applied applications and Safe2Torch details using hot-air.

Scope

  • Underlay in self-protected two-layer bonded systems.
  • Underlay in two-layer systems with bonded and unbonded or floating heavy duty protection.
  • Underlay in multi-layer systems with mineral self-protection for waterproofing of railway decks.
  • Single-layer membrane for waterproofing roofs with heavy bonded, unbonded or floating protection.
  • Radon gas barrier in slabs, sanitary slabs or walls.

Advantages & Benefits

  • High resistance to static and dynamic piercing.
  • Self-healing and rot-proof.
  • High dimensional stability.
  • High tensile strength and high elongation at break.
  • High resistance to tearing.
  • Total impermeability to water and water vapour.
  • Very stable in the long term.
  • Allows for adaptation to any type of geometry.

Support

  • Slab to wall joint
  • Concrete subsrates.
  • Timber.
  • Mortar subsrates.

Substrate preparation

  • The support must be healthy, clean, flat, free of paint, crumbling or poorly adhered parts, release agents, etc. and in general without any substance or particle that may prevent correct adherence.

Instruction for Use



  • Substrate should be dry and clean from grease, dirt, debris or any other contaminants.
  • Where applicable, prime surface with CURIDAN or BITUMEN PRIMER+ in accordance with DANOSA instructions and allow to dry.
  • For field applications: 
  • Roll the membrane into position, allowing for 80mm side overlaps and100mm head overlaps and cut to length. All overlaps and cross joints should be staggered by a minimum of 300mm.
  • Using a length of 100mm ø pipe (cut fractionally short of roll width) as an insert tube, roll back the membrane for a portion of the length (approximately 50%).Heat activate the membrane by torching in a vee area between the roll and substrate.
  • 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.
    • 4. For detail applications
  • Place the membrane into position, allowing for 80mm side overlaps and100mm head overlaps and cut to length ensuring all overlaps and cross joints are staggered by a minimum of 300mm.
  • Heat activate the membrane by torching between the membrane and substrate.
  • Apply pressure and consolidate the bond to the substrate, ensuring a molten bead of bitumen is extruded from the edges.
  • Where specified, POLYDAN 180-40/P ELAST head laps should be mechanically fastened with DANOSA SUREFAST tubes or pressure plates and the appropriate mechanical fasteners at a minimum of 200mm centres in accordance with DANOSA instructions.


    • Where falls apply, membrane rolls should be rolled up the slope so that water drains over and not into membrane overlaps.

    Indications and Important Recommendations

    • In case of new construction and renovation, possible chemical incompatibilities with APP plastomer-modified bitumen sheets shall be taken into account.
    • In case of refurbishment, chemical incompatibilities with old waterproofing systems consisting of PVC membranes, modified tar-based mastics or any other, shall be taken into account, and it may be necessary to remove them completely or to use suitable separating layers.
    • If it is necessary to adhere to metallic or slightly porous elements, a bituminous primer (IMPRIDAN 100) shall be applied to the entire surface to be welded beforehand.
    • This product may form part of a waterproofing system, so all the documents referred to in the Danosa Solutions Manual must be taken into account, as well as all the regulations and legislation that must be complied with in this respect.
    • Not suitable as cap sheet on green roofs; use GARDEN variant.
    • Possible incompatibility between thermal insulation and waterproofing shall be checked.
    • Special attention must be paid to the execution of the singular points, such as parapets (meetings with vertical and emergent elements), drains, expansion joints, etc.
    • Polyurethane foam shall not be sprayed directly on top of the waterproofing without the use of a suitable separating layer (geotextiles, mortar layers, polyethylene film, etc).
    • If expansion that could affect the sheet is expected, a geotextile separating layer (Danofelt PY 200) shall be used between the sheet and the extruded polystyrene insulation panels, so that each product expands independently.
    • NOTE: For more information on the Danosa systems in which this product is used, please see the document "Waterproofing Solutions".

    Maintenance Recommendations

    • Please refer to DANOSA UK Technical Statement ‘Flat Roof Waterproofing – Cleaning and Maintenance Recommendations’

    Warning
