POLYDAN PRO 50/GP GREEN GARDEN.

First-rate SBS elastomeric 5 kg/m² capping sheet. Root Inhibitor.

Product variations:
Waterproofing
BBA 10/4787 (PS2) BBA 10/4787 (PS2)
High quality bituminous SBS modified capsheet reinforced with a heavy non-woven polyester felt. Includes root-resistant additive for living roof specifications. The upper surface is finished with grey-green mineral chippings. The underside has a quick-melt thermofusible film. Designed for torch-applied applications and Safe2Torch details using hot-air.

Scope

  • Tanking membrane.
  • Capsheet in multi-layer waterproofing systems.
  • Top sheet in two-layer membranes for waterproofing of roofs with heavy bonded, unbonded or floating protection.
  • Single-layer membrane for waterproofing intensive and extensive green roofs.
  • Single-layer membrane for waterproofing roofs with heavy bonded, unbonded or floating protection.

Advantages & Benefits

  • High resistance to static and dynamic piercing.
  • The mineral finish gives the membrane UV resistance.
  • High resistance to root penetration.
  • High tensile strength and high elongation at break.
  • High resistance to tearing.
  • Total impermeability to water and water vapour.
  • Rot-proof.
  • Very stable in the long term.
  • Allows for adaptation to any type of geometry.

Support

  • Old bitumen membranes.
  • Concrete subsrates.
  • Mortar subsrates.

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:
  • POLYDAN PRO 50 GARDEN 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.
  • 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. Overlaps and cross joint
  • 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.
  • For detail applications
  • POLYDAN PRO 50 GARDEN 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.
  • POLYDAN PRO 50 GARDEN must be installed a minimum of 150mm above the finished surface of the living (green roof) system.
  • 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 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.
    • In the case of large trees and/or large root tissue, the membrane shall be protected (horizontal section and junctions with vertical walls) with a layer of reinforced concrete.
    • 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.
    • Self-protected sheets in coloured mineral or ceramic granules may have different colour shades depending on the different production batches. The mineral granule may darken naturally over time.
    • There is no chemical incompatibility between the Danosa range of SBS elastomeric bitumen and APP plastomeric bitumen membranes.
    • The planting of palms, palm trees, cypresses and bamboos is not recommended.
    • For any questions about prohibited and/or non-recommended plants, please consult our Technical Department.
    • Possible incompatibility between thermal insulation and waterproofing shall be checked.
    • A separating layer (DANOFELT or DANODREN) shall be laid before laying the heavy protection (paving, gravel, topsoil, etc).
    • 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’
