DANOSA ESTERDAN 30 P ELAST - 12m x 1m

• Total impermeability to water and water vapour
• High tear resistance for tough applications
• Excellent resistance to static and dynamic piercing
• Strong tensile strength with high elongation at break
• Long-term stability and durability
• Adapts easily to complex building geometries
• Self-healing and rot-proof properties for added reliability

• Buried Structures & Tanking: Effective as a protective waterproofing layer for underground works.
• Roof Waterproofing: Suitable as a bottom or top sheet in two-layer roofing systems with heavy bonded, unbonded, or floating protection.
• General AVCL and waterproofing projects where a robust, reinforced SBS membrane is required.

Important Recommendations:

• Not suitable for use as a cap sheet on green roofs – use the GARDEN variant.
• Not intended for single-layer waterproofing.
• Always install with a separating layer (e.g. DANOFELT or DANODREN) before applying heavy protection such as gravel, paving, or soil.
• May form part of a larger waterproofing system – refer to the Danosa Solutions Manual and comply with relevant standards and regulations.
• Compatible with both SBS elastomeric and APP plastomeric membranes.
• Apply a bituminous primer (IMPRIDAN 100) when adhering to metallic or slightly porous substrates.
• Use a geotextile separating layer (e.g. Danofelt PY 200) where thermal expansion between insulation and membrane could cause stress.
• Avoid spraying polyurethane foam directly onto the sheet – always apply a suitable separating layer.
• In refurbishment, check for chemical incompatibilities with old PVC, tar-based, or other waterproofing systems.
• In new builds, account for potential incompatibility with APP plastomeric-modified bitumen sheets.

What is ESTERDAN 30 P ELAST. used for?

It is designed for use in buried structures, tanking applications, and as part of two-layer roofing systems with heavy protection.

Can ESTERDAN 30 P ELAST. be used as a single-layer waterproofing system?

No, it must always be used within a multi-layer system and is not suitable as a standalone solution.

Is this membrane compatible with other bitumen sheets?

Yes, it is chemically compatible with SBS and APP bituminous membranes, but potential incompatibilities should be checked in refurbishment projects.
