ESHASTICK P-P | Self-adhesive elastomeric bituminous waterproofing membrane
Specialised bituminous membranesDescription
A state-of-the-art self-adhesive bituminous membrane for waterproofing, manufactured from SBS-modified bitumen, which provides exceptional elasticity and enhanced viscoelastic properties at very low temperatures (-25°C), combined with special additives that provide self-adhesive properties. It adheres easily to a suitably prepared substrate without the need for a blowtorch, making it ideal for waterproofing rigid structural elements and for environments where open flames are prohibited. It is manufactured with double reinforcement of SP polyester and aluminium, with upper and lower polyethylene film coatings, weighing 2.5 kg/m² and 2.5 mm thick. A key feature is its elastic recovery, which exceeds 90 per cent — and remains above 90 per cent even after ageing.
The ARGYNET View: Cold application is not just a matter of site safety — it is also a matter of the substrate. It is bonded directly to PU/XPS boards and timber, where the use of a blowtorch is simply not permitted. Important note: the primer used here is ESHALAC 50S (solvent-based, thinned with petrol) — not water-based.
Overview
Key Features
Elasticity & durability
- Elastic recovery of asphalt mixture >90% (EN 13398)
- Retains >90% recovery even after ageing — longevity index
- Softening point >105°C (EN 1427), penetration 85 dmm at 25°C
- Flexibility at low temperatures of -25°C (EN 1109)
- Resistance to extreme weather conditions
- Enhanced viscoelastic properties due to SBS modification
Flame-free application
- Cold application — higher level of workplace safety
- Quick and easy installation, resulting in low labour costs
- Excellent adhesion to hard, smooth, prepared and primed surfaces
- Suitable for substrates that cannot withstand a blowtorch (PU, XPS, timber)
- Below 5°C, adhesion is enhanced by gentle heating (hot-air gun)
Structure & reinforcement
