Polyester fleece 110 g/m² – roll 0.50 × 50 m – reinforcement fleece for surface roof waterproofing

The Polyester fleece 110 g/m² in 50 cm roll width is primarily for the Full-surface reinforcement of liquid waterproofing systems used.
With this type of processing, cracks, transitions and detail areas are automatically reinforced, so that in many cases no additional localized crack or detail reinforcement is required.

The large roll width allows vertical components such as parapets, upstands or connections to be securely integrated in one operation.
The fleece is compatible with Liquid plastic, bitumen and PU systems and is suitable for both new buildings and for the renovation of existing waterproofing systems.

Applications

• Surface reinforcement of liquid waterproofing systems on flat roofs

• New construction and renovation waterproofing of roof surfaces

• Automatic reinforcement of cracks and transitions during full-surface application

• Reinforcement of parapets, upstands and connections (up to approx. 40 cm height)

• Production of reinforcing strips and sleeves for aerators, fans and roof drains

• Full-surface sealing of balconies and terraces

• Reinforcement of foundation waterproofing

• Separation and filter layer in garden and path construction (e.g. under paving and walkways)

Benefits at a glance

• Ideal for surface reinforcement liquid waterproofing systems

• Uniform stress distribution across the entire surface

• High crack bridging capacity and mechanical strength

• Reduces the need for additional detail and crack reinforcement.

• Large roller width enables efficient work on large surfaces

• Dimensionally stable, tear-resistant and flexible

• Easy to cut and easy 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)

The quality of this Reinforcing fleece was tested by an independent institute:

• Tensile strength (N/50 mm): lengthwise 152, crosswise 110
• Elongation at maximum tensile force (%): longitudinal 52.5 %, transverse 79.2 %
• Elongation at break (%): longitudinal 53.0 %, transverse 81.1 %

👉 These results confirm the excellent tear resistance and elasticity of the material. This makes our Polyester fleece 110 g/m² ideally suited for waterproofing applications subject to permanently high loads.

Technical data

• Sealing of parapets without additional detail strips

• Production of wide reinforcements for roof drains and fans

• Extensive foundation sealing with increased safety

Instructions for use

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

• Place polyester fleece into the fresh sealant and saturate it completely.

• Lanes approx. overlap by 5–10 cm

• Carefully incorporate at connections, parapets and penetrations.

• Then completely recoat with sealing 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

• 50 cm roll width – ideal for full-surface reinforcement of flat roofs, terraces, and accessible roof areas. When applied over the entire surface, cracks, transitions, and detail areas are automatically reinforced. (current selection)

Frequently Asked Questions (FAQ)

❓ Why is the 50 cm roll width particularly suitable for surface reinforcement?
✅ The large width allows for uniform, continuous reinforcement of the sealing surface and ensures that cracks, transitions and details are automatically reinforced.

❓ Does the 50 cm version replace narrower roll widths?
✅ No. Narrower roll widths (15, 25, or 35 cm) remain the more economical solution for targeted detail work and spot repairs. The 50 cm version is specifically designed for surface reinforcement.

❓ Can I also use the fleece for detailed work?
✅ Yes, the material can be cut to size and used for details. However, its main advantage lies in its suitability for covering entire surfaces.

❓ Is the polyester fleece compatible with PU and liquid plastics?
✅ Yes, compatible with bitumen, PU and liquid plastic systems. This Reinforcing fleece Works reliably in all common systems.

❓ How long does the polyester fleece last in a waterproofing system?
✅ When processed correctly, the fleece significantly increases the service life of the sealing system, as it distributes stresses and prevents cracking.

❓ Custom cutting?
✅ Easily done with scissors or a cutter.

❓ Overlap width?
✅ 5–10 cm per joint is recommended for a permanently tight seal.

❓ UV resistance?
✅ Designed for installation under sealing systems; cover in case of direct UV exposure.

❓ Can it be used in sub-zero temperatures?
✅ The fleece can be applied at sub-zero temperatures. It is crucial that the sealing material used (e.g., liquid plastic or bitumen) is approved for low temperatures.

❓ Storage?
✅ Store in a dry place, protected from UV light; ideally in a covered, well-ventilated room.
