SikaBit® E 15-15 HDPE XL SA

PEEL AND STICK, SELF-ADHESIVE, BITUMINOUS SHEET WATERPROOFING MEMBRANE FOR BELOW GROUND APPLICATIONS

SikaBit® E 15-15 HDPE XL SA is a self-adhesive bituminous sheet waterproofing membrane. It's based on a SBS modified bitumen compound on a cross-laminated HDPE film, formulated for hot and tropical climate.

  • Cold-applied and self-adhesive (no heating or open flames required)
  • Fully bonded sheets
  • Resistant to aggressive mediums in natural ground water and soil
  • Controlled layer thickness
  • Easy, fast and secure application, without special equipment
  • Split release liner for easy application

Usage

SikaBit® E 15-15 HDPE XL SA is a cold and post-applied self-adhesive sheet waterproofing membrane. The system is applied on existing below ground concrete structures to provide damp-proofing and waterproofing:
  • On horizontal slabs and protrusions
  • On single and strip foundations or slabs
  • On the outside of external walls
 

Advantages

  • Cold-applied and self-adhesive (no heating or open flames required)
  • Fully bonded sheets
  • Resistant to aggressive mediums in natural ground water and soil
  • Controlled layer thickness
  • Easy, fast and secure application, without special equipment
  • Split release liner for easy application

Packaging

1.05 m x 15 m single roll

Colour

Supplied as sheets in rolls, on one side a black HDPE carrier film and on the other the black bitumen compound adhesive protected with a peel-release film.

Application

Application Information

Ambient Air Temperature

+5 °C min. / +50 °C max.

Relative Air Humidity

<80 %

Dew Point

The substrate temperature must be at least 3 °C above the dew point to reduce the risk of condensation and so limited adhesion

Substrate Temperature

+5 °C min. / +50 °C max.

Substrate Moisture Content

Dry, ≤ 4 % moisture content, no rising moisture
Application steps

SUBSTRATE QUALITY

The substrate must be uniform, firm, smooth and free of any sharp protrusion or burrs, clean, dry, free of grease, bitumen, oil, dust and loosely adhering particles.

SUBSTRATE PREPARATION

Unevenness and surface defects (such as blowholes, voids, honeycombing, cracks, protrusions, etc.) in the surface must be pretreated and filled prior to the application, in order to prevent any subsequent damage to the membrane sheets. For more detailed information please refer to the current Method Statement for the SikaBit® E 15-15 HDPE XL SA membrane system.

 


A suitable primer has to be used for an optimal bond between SikaBit® E 15-15 HDPE XL SA membrane sheets and the concrete substrate, for example:

  • SikaBit® P-11 SA
  • SikaBit® P-12 AE
