ESTERDAN 30 P ELAST. AUTOADHESIVO is a waterproofing bituminous self-adhesive membrane. Composed of a non-woven polyester felt reinforcement, covered with SBS modified bitumen mastic, self-adhesive on the lower side. A polyethylene film is used as anti-adherent material on the top side and a siliconized releasable polypropylene film is used on the bottom side. 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.
High resistance to tearing.
High tensile strength and high elongation at break.
High resistance to static and dynamic piercing.
Rot-proof.
Very stable in the long term.
Improves the performance of mechanically fastened sheets by providing a high wind suction resistance value and optimising the density of fastenings.
Absorbs structural movements well.
Good anti-piercing protection from mechanical damage.
It retains its properties better over time.
Helps to increase the durability of the sheet.
The sheet can be combined, in two-ply membranes, with a sheet reinforced with glass fibre felt, which provides the waterproofing system with dimensional stability, of great importance in bonded systems.
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”). Two-ply self-protected membrane underlay mechanically fastened to the deck roof.
Waterproofing sheet on the outside of walls. Preparation of the substrate:
The surface of the base substrate must be resistant, uniform, smooth, clean, dry and free of foreign bodies.
In the case of mortar or concrete substrates, first apply a bituminous primer (Curidán, Impridán 100, Maxdán or Maxdán Caucho).
In the case of wooden substrates, an Impridán 100, Maxdán or Maxdán Caucho bituminous primer shall be applied beforehand.
In case the substrate is a thermal insulation board, the compatibility between both materials shall be verified.

Application of the sheet:
– The adhesion to the substrate of the sheet is carried out by removing the protective film and pressing outwards to avoid the formation of air bubbles.
– The overlaps must be adhered, and shall be 8 cm in both longitudinal and transverse directions.
– 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 8-10 cm, eliminating the protective polyethylene film in the bituminous mass and then adhere the end of the following piece.
Waterproofing of walls:
– Previously apply a bituminous primer (Curidán, Impridán 100, Maxdán or Maxdán Caucho).
– The rolls are placed in a vertical position.
– The adhesion of the film to the substrate is done by removing the protective film and pressing outwards to avoid the formation of air bubbles.
– The overlaps must be adhered and should be 8 cm in both longitudinal and transverse directions.
– For easier installation, it is recommended to cut the rolls into smaller, more manageable dimensions.
– 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 strip of 8-10 cm beforehand, removing the protective polyethylene film in the bituminous mass and then adhere the end of the next piece. It shall be stored in a dry place protected from rain, sun, heat and low temperatures.
It must not be installed when the ambient, product or substrate temperature is below +10°C.
In cold weather, it is advisable to slightly heat the support with the blowtorch.
Exposure to the sun can make it difficult to remove the release film. The temperature of the sheet during installation must not exceed 45°C.
It should be kept in the sun for as short a time as possible to protect it from UV rays.
In case the substrate is a thermal insulation board, the compatibility between the two materials shall be verified.
To join the transverse overlap at the ends of the rolls, it is necessary to preheat the transverse edge of the bottom sheet in a strip of 8-10 cm, remove the protective polyethylene film in the bituminous mass and then adhere the end of the next piece.
Do not use as a top sheet on green roofs.
On flat roofs, it cannot be used as a waterproofing system.
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.
A separating layer (DANOFELT or DANODREN) must be laid before laying the heavy protection (paving, gravel, topsoil, etc.), except in the case of waterproofing under tiles.
There is no chemical incompatibility between the Danosa range of SBS elastomeric bitumen and plastomeric bitumen sheets.
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.
Possible incompatibility between thermal insulation and waterproofing shall be checked.
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.
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).
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).
In case of new construction and renovation, possible chemical incompatibilities with APP plastomer-modified bitumen sheets shall be taken into account.
NOTE: For more information on the Danosa systems in which this product is used, please see the document “Waterproofing Solutions”.
