Polyester fleece 110 g/m² – roll 0.35 × 50 m

Polyester fleece 110 g/m² – Roll 0.35 × 50 m Reinforcing fleece for roof waterproofing

The Polyester fleece 110 g/m² in a 35 cm roll width is the ideal solution for more demanding detail waterproofing and partial reinforcement on flat roofs.
Due to its greater width, it is particularly suitable for Roof drains, gullies, fans, aerators and transitions subject to increased mechanical stress.

The fleece ensures even stress distribution, high crack bridging and permanent integration into liquid waterproofing, bitumen and PU systems.

Applications

• Reinforcement of Roof drains, gullies and drainage points

• Waterproofing of aerators, fans and pipe penetrations

• Transitions between roof surface and upstand

• Inside and outside corners with greater overlap requirements

• Partial reinforcement of flat roofs during renovations

• Reinforcement of critical detail areas subject to increased stress

Benefits at a glance

• Greater coverage for complex details and penetrations

• Ideal for round and geometrically complex components

• High tear resistance and dimensional stability

• Uniform stress distribution within the waterproofing layer

• Easy to cut and flexible to process

• Compatible with liquid waterproofing, bitumen and PU systems

• Certified quality according to DIN EN ISO 10319

Certified quality

(iBMB MPA Braunschweig, Test report no. 22188/2024)

• Tensile strength (N/50 mm): longitudinal 152, transverse 110

• Elongation at maximum tensile force (%): longitudinal 52.5 %, transverse 79.2 %

• Elongation at break (%): longitudinal 53.0 %, transverse 81.1 %

These values confirm the high elasticity and resilience of the material – ideal for detail areas that must permanently accommodate movement.

Technical data

• GSM: 110 g/m²
• Roll size: 0.35 × 50 m
• Colour: white
• Material: 100 % Polyester (PES)
• Application: Reinforcement of liquid waterproofing membranes
• Substrate: bitumen, PU, PMMA, liquid waterproofing

Practical examples

• Reinforcement of gullies during flat roof renovations

• Waterproofing of roof vents and aerators

• Reinforcement of transitions in older roof structures

• Partial reinforcement before applying new waterproofing

• Remediation of damage-prone drainage details

Instructions for use

• Thoroughly clean the surface and ensure it is dry and load-bearing.

• Embed the fleece into the fresh liquid waterproofing material and fully saturate it.

• Overlap of the lanes approx. 5–10 cm

• Pay particular attention to incorporating details, especially at processes and penetrations.

• Then fully cover with waterproofing material.

What width is suitable for my project?

• 15 cm roll width – ideal for transitions, internal and external corners, pipe penetrations and precise detail work.

• 25 cm roll width – ideal for larger connections, parapets and transitions with increased safety margin

• 35 cm roll width – ideal for roof drains, gullies, fans, aerators and heavily stressed connection areas (current selection)

• 50 cm roll width – Ideal for full-surface reinforcement of flat roofs, terraces, and usable roof areas. When applied over a large area, cracks, transitions, and detail areas are automatically reinforced.

Frequently Asked Questions (FAQ)

❓Why is the 35 cm roll width particularly suitable for roof drains?
✅The greater width allows for secure, all-around coverage of drains, fans and penetrations, reducing the risk of stress cracks.

❓Can I also use the fleece to cover a large area?
✅Yes, the 35 cm width is very suitable for partial reinforcements during renovations or in particularly stressed areas.

❓Is the fleece suitable for PU liquid waterproofing?
✅Yes, the polyester fleece is compatible with PU, bitumen and other liquid waterproofing systems..

❓ Do I need to cut the fleece?
✅ Yes, it can easily be cut to size with scissors or a cutter.

❓ How wide should the overlap of the lanes be?
✅ We recommend an overlap of 5–10 cm to ensure a tight seal.

❓ Is the product UV-resistant?
✅ The fleece is intended for use within waterproofing systems. It should be covered in case of direct UV exposure.

❓ Can polyester fleece be used in sub-zero temperatures?
✅ Yes, the fleece itself can be used without any problems in sub-zero temperatures. It is important that the waterproofing material used (e.g. PU liquid waterproofing or bitumen) is also approved for low temperatures. In combination with frost-resistant materials, the fleece will function reliably even in winter.

❓ How should the polyester fleece be stored?
✅ Store the fleece in a dry place, protected from direct sunlight and UV light. A covered, well-ventilated room is ideal. This will ensure the rolls retain their shape and can be easily processed even after prolonged storage.

❓ Is the polyester fleece easy to cut?
✅ Yes, the fleece can easily be cut to the desired length with ordinary scissors or a sharp utility knife. The material does not fray and retains its shape.

❓ How long does the polyester fleece last in a waterproofing system?
✅ When installed correctly, the fleece ensures a durable and reliable seal. It reinforces the coating, distributes stress evenly, and prevents cracking – thus significantly extending the service life of the waterproofing system.
