LL-32002 DFA Polymer Modified Bitumen Root-Resistant Waterproof Membrane
Standard: GB/T 35468-2017
Product Overview:
LL-32002 DFA polymer modified bitumen root-resistant waterproof membrane uses styrene-butadiene-styrene (SBS) thermoplastic elastomer as a modifier. It includes chemical root inhibitors to effectively prevent plant roots from growing into the waterproof layer. The membrane is reinforced with polyester fabric and has a polyethylene film (PE) surface for separation, making it a flexible, rollable waterproof material.
Product Features:
- High Tensile Strength: Excellent dimensional stability, accommodating base layer shrinkage and cracking.
- Low Temperature Resistance: Suitable for various climatic conditions.
- Puncture and Tear Resistance: High durability against puncture, abrasion, tear, corrosion, mold, and weathering.
- Chemical Root Resistance: Prevents plant roots from penetrating without affecting plant growth.
- Excellent Waterproofing: Provides long-lasting resistance to dynamic underground water pressure.
Construction Process:
- Base layer treatment
- Application of base layer treatment agent
- Construction of additional waterproof layer for detailed parts
- Construction of main waterproof membrane layer
- Quality inspection and acceptance
- Construction of protection and isolation layer
Scope of application：
Suitable for planting roofs, rooftop gardens, garage roofs, and building roofs that require greening.
Construction process：
Base Treatment → Primer Application → Detailed Additional Waterproof Layer Construction → Main Membrane Waterproof Layer Construction → Quality Inspection and Acceptance → Protection and Isolation Layer Construction
