POLYDAN 180-60/GP ELAST. is a waterproofing bituminous sheet with self-protected surface of 5.6 kg/m². Composed of a non-woven polyester felt reinforcement, covered on both sides with SBS modified bitumen mastic. On the upper side of the sheet, mineral protection in grey (black) colour is used as protective material. The anti-adhesive material used on the lower side is polyethylene film.

Scope

  • The mineral finish gives the sheet UV resistance, which is necessary for visible waterproofing. Therefore, this sheet can be used as a top layer in two-layer membranes with heavy bonded protection in place of the plasticised sheet, in those cases where it is foreseen that a certain time will elapse between the execution of the waterproofing and the protection.
  • Basement wall waterproofing.
  • Top sheet of two-layer membranes with mineral self-protection for waterproofing boards.
  • Multilayer membrane top sheet with mineral self-protection for waterproofing of carpark roofs (parking roofs or rolling surfaces, etc.), where the agglomerate is poured directly on top of the waterproofing.
  • Multilayer membrane top sheet for roof waterproofing with mineral self-protection.
  • Bonded self-protected single-layer membrane for waterproofing carpark roofs (parking decks or rolling surfaces, etc.), where the agglomerate is poured directly on top of the waterproofing.
  • Bonded self-protected single-layer membrane for waterproofing boards.
  • Single-layer membrane for waterproofing bonded self-protected roofs.

Advantages & Benefits

  • Absorbs structural movements well.
  • Helps to increase the durability of the sheet.
  • It retains its properties better over time.
  • It has a heavy polyester felt reinforcement, heavier than LBM-(SBS)-50/G-FP sheets.
  • It has a nominal mass of 5.6 kg/m2, which is higher than the 5.0 kg/m2 of LBM-(SBS)-50/G-FP. The higher mass of SBS elastomeric bitumen increases the durability of the waterproofing and makes it easier to lay the sheet.
  • The higher grammage of the polyester reinforcement gives the sheet higher mechanical performance in tensile, static and dynamic piercing.
  • It is a sheet for cases where high waterproofing performance is required.
  • This sheet is suitable for waterproofing buried structures (basement walls) with a favourable technical evaluation (see DIT 567/11 "ESTERDAN - SELF DAN - POLYDAN BURIED STRUCTURES").
  • This sheet is suitable for the waterproofing of structures subject to vehicular traffic (road and railway decks, rolling and carpark roofs, underground, etc.) with a favourable technical evaluation (see D.I.T. 569/11 "POLYDAN ROLLING TRAFFIC").
  • High tensile strength and high elongation at break.
  • High resistance to static and dynamic piercing.
  • Rot-proof.
  • The sheet, being made of a bitumen mastic modified with SBS-type elastomeric polymers, substantially improves other bituminous mastics, providing much better performance in terms of reaction at high and low temperatures, elasticity and resistance to ageing, which leads to greater durability of the sheet and greater safety of the waterproofing membrane.
  • Thanks to the mineral finish, the nominal mass and the grammage of the reinforcement, the sheet allows the asphalt agglomerate to be poured directly on top of the waterproofing on accessible vehicle roofs (carpark roofs or rolling surfaces, bridge decks, etc).
  • Very stable in the long term.
  • Has good piercing protection from possible mechanical damage, derived from the occasional pedestrian traffic typical of flat roofs.

Instruction for Use

Preparation of the substrate:
-The surface of the base substrate shall be resistant, uniform, smooth, clean, dry and free of foreign bodies. In the case of thermal insulation, the boards shall be laid in a grid and with no gaps between boards greater than 0.5 cm.
  • Top layer of multi-layer membranes with mineral self-protection. The sheet is laid in the same direction as the bottom sheet, with the overlap line offset by approximately half of the roll. The sheet is fully welded to the bottom sheet with a blowtorch. The overlaps are to be welded and are 8±1 cm in the longitudinal direction and 10±1 cm in the transverse direction. To join the transverse overlap at the ends of the rolls, it is necessary to heat the transverse edge of the lower sheet in a 10 cm strip, eliminating or embedding the protection aggregate in the bituminous mass and then weld the end of the following piece.
  • Self-protected single-layer membrane, adhered system. The adhesion of the membrane to the substrate is done with a blowtorch. In the case of mortar or concrete substrates, a bituminous primer (Curidán, Impridán 100, Maxdán or Maxdán Caucho) must be applied beforehand. If the substrate is a weldable thermal insulation board, i.e. asphalt-finished (Rocdán A or Rocdán PIR VA), no primer is required. The overlaps must be welded, and shall be 8±1 cm in the longitudinal direction and 10±1 cm in the transverse direction. To join the transversal overlap at the ends of the rolls, it is necessary to previously heat the transversal edge of the lower sheet in a strip of 10 cm, eliminating or embedding the protection aggregate in the bituminous mass and then weld the end of the following piece.
  • Waterproofing of walls. First apply a bituminous primer (Curidán, Impridán 100, Maxdán or Maxdán Caucho). For ease of installation, it is recommended to cut the rolls into smaller, more manageable dimensions, adjusting them to the width of the wall.

Indications and Important Recommendations

  • During paving, sharp turns and sudden braking of the paver should be avoided and paver speed should be limited.
  • In the case of new construction and renovation work, the possible chemical incompatibilities with SBS elastomer-modified bitumen sheets must be taken into account.
  • In case of renovation, chemical incompatibilities with old waterproofing consisting of flexible PVC sheets, 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 (geotextiles, mortar layer, polyethylene film, etc).
  • 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.
  • On exposed self-protected roofs, occasional water retention that could lead to sediment accumulation and damage to the waterproofing membrane shall be avoided.
  • 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.
  • Certain precautions must be taken when pouring the asphalt agglomerate if it is poured directly on top of the waterproofing.
  • The asphalt paver shall be wheeled and, if tracked, shall be fitted with rubber pads.
  • The asphalt agglomerate shall be laid at temperatures between 130ºC and 180ºC.
  • Self-protected sheets in coloured mineral or ceramic granules may have different colour shades depending on the different production batches.
  • NOTE: For more information on the Danosa systems in which this product is used, please see the document "Waterproofing Solutions".
  • There is no chemical incompatibility between the Danosa range of oxyasphalt, SBS elastomeric bitumen and plastomeric bitumen sheets.
  • The waterproofing must not be walked on.
  • Do not use as a top sheet on green roofs.
  • A separating layer (DANOFELT or DANODREN) shall be laid before laying the heavy protection (paving, gravel, topsoil, etc.), except in the case of asphalt paving which is poured directly on the waterproofing.
  • 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).

Maintenance Recommendations

  • Maintenance requirements for Danosa Roofing Products The following maintenance checks must be adhered to: - A general examination on the condition of the waterproofing and surrounding roof components. - An inspection of all functional roofing elements including skylights, outlets, upstands, penetrations and any other visible roofing components. - Clean outlets, drains, gutters and remove any debris from the roof. - Periodic removal of mildew, moss, herbs or any other kind of vegetation that has been accumulation on the waterproofing. - Periodic removal of possible sediments accumulated on the deck (silt, sledges, slate granules, etc) by occasional water accumulation. - Periodic removal of debris and small objects that may have accumulated on the roof. - Ensure surrounding structural elements are sound such as eaves, flashings, slate tiles and brickwork. - Ensure that the waterproofing is in good condition and there are no blisters, damage or separation. - Review the condition of the waterproofing (adherence to upstands, condition of overlaps, visual appearance, etc) and repair the defects observed. These operations must be carried out twice a year, preferably at the beginning of spring or autumn and must be increased in case of decks or valleys with zero falls. It is also necessary to perform additional maintenance depending on the type of roof, location and proximity of roofs to areas with trees or in areas with high levels of pollution.
