SKU: 141015 More from this category:
ESTERDAN PLUS 50/GP ELAST. is a waterproofing bituminous sheet with self-protected surface of 5.0 kg/m². Composed of a reinforced 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

  • Waterproofing under tiles on pitched roofs, both for its thickness and its mechanical resistance.
  • Top sheet in multi-layer roof waterproofing systems with mineral self-protection. Typically installed over Esterdan 30 P Elast. 
  • Single-layer membrane for waterproofing bonded self-protected roofs.

Advantages & Benefits

  • High static and dynamic piercing resistance.
  • Self-healing and Rot-proof.
  • The mineral finish gives the sheet UV resistance.
  • 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

  • Roofs with heavy bonded, unbonded or floating and self-protected bonded protection.
  • Over compatible thermal insulation.
  • Concrete supports
  • Mortar supports

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), the primer is not necessary. The overlaps are to 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 under tiles on pitched roofs. Proceed as described above, but mechanically fasten the 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 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.
  • Self-protected sheets finished in light colours perform better thermally.
  • Self-protected sheets in coloured mineral or ceramic granules may have different colour shades depending on the different production batches.
  • Self-protected sheets are exposed sheets, so care must be taken when installing them.
  • NOTE: For more information on the Danosa systems in which this product is used, please see the document “Waterproofing Solutions”.
  • Do not use as a top sheet on green roofs.
  • 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.

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.
