Waterproofing
BBA 10/4787 (1) BBA 10/4787 (1)
High quality 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.

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

  • Stripping of walls.
  • Concrete subsrates.
  • Wooden subsrates.
  • 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

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 flush with each other and without gaps of more than 0.5 cm between boards.
  • Single-ply adhered system membrane, double-ply adhered system membrane bottom sheet with heavy-duty protection and double-ply self-protected membrane bottom sheet. The adhesion of the membrane to the substrate is carried out 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. finished in asphalt, the primer is not necessary. The overlaps must be welded and shall be 8 cm in both longitudinal and transverse directions.
  • Top sheet of two-layer waterproofing membranes with heavy protection. The sheet is laid in the same direction as the bottom sheet, shifting the overlap line 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 shall be 8 cm in both longitudinal and transverse directions.
  • Single-ply unbonded or floating system membrane and bottom sheet two-ply unbonded or floating system membrane with heavy protection. In this case the membrane is only welded to the substrate at the singular points (parapets, expansion joints, drains, etc.), where a bituminous primer (Curidán, Impridán 100, Maxdán or Maxdán Caucho) has been previously applied. Non-adherence to the substrate must be guaranteed and a separating layer (Danofelt PY 150 or Velo 100) may be necessary between the substrate and the waterproofing membrane. The overlaps must be welded, and shall be 8 cm in both longitudinal and transversal directions.

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".
