PVC Membrane LOGICROOF V-GR Approved for Green Roof Systems

Introduction: Green Roofs Are Becoming Essential in India

Across major Indian cities — Mumbai, Bengaluru, Delhi NCR, Hyderabad — developers are increasingly adopting green roofing systems to reduce heat load, manage stormwater and improve building sustainability.

To ensure long-term waterproofing in India’s challenging climate (intense heat, UV radiation, and heavy monsoons), TECHNONICOL has developed a dedicated membrane: LOGICROOF V-GR, specially engineered and approved for green roof applications.

Why India Needs Specialized Waterproofing for Green Roofs

Green roofs place continuous moisture, root pressure, and biological activity directly on top of the waterproofing layer. In hot and humid Indian regions, membranes face additional challenges:

1. High UV Radiation & Temperature

Indian roof surfaces can reach 70°C, requiring materials with excellent heat and UV stability.

2. Intense Monsoon Rains

Cities like Mumbai and Chennai experience extreme rainfall. Waterproofing must resist standing water and root moisture penetration.

3. Root Resistance

Plant roots can mechanically penetrate weak waterproofing layers. LOGICROOF V-GR includes a reinforced root-resistant formulation, preventing long-term biological damage.

4. Load from Soil & Vegetation

Green roofs add substantial structural load. Membranes must remain stable under pressure and continuous moisture.

LOGICROOF V-GR: Engineered for Sustainable & Durable Green Roofs

The LOGICROOF V-GR membrane is designed to function reliably beneath soil layers, drainage boards and vegetation in India’s climate.

Key Features of LOGICROOF V-GR

✔ Certified Root Resistance

The membrane passed root-penetration resistance tests and is officially approved for use in green roof systems.

✔ High Mechanical Strength

Maintains integrity under soil load, foot traffic during installation and movement of green roof components.

✔ Superior Chemical & Biological Resistance

Resists fertilizers, soil acids, moisture, and bacterial activity found in green roof environments.

✔ UV- and Heat-Resistant

Critical for India’s warm and tropical regions.

✔ Compatible with Extensive & Intensive Green Roofs

• Extensive systems: sedum, grasses
  
  

• Intensive systems: shrubs, small plants, rooftop gardens
  

✔ Long Service Life

Based on TECHNONICOL’s test data, the membrane maintains long-term elasticity and waterproofing performance even under constant root and moisture contact.

Application Areas in India

LOGICROOF V-GR is suitable for both commercial and residential projects, including:

• Residential high-rise terraces

Ideal for premium projects in Mumbai, Pune, Delhi NCR.

• Commercial office buildings

Green roofs reduce heat gains and improve LEED/BREEAM scoring.

• Hotels & rooftop gardens

Increasingly popular in Goa, Bengaluru, Jaipur.

• Institutional & public buildings

Hospitals, universities, and parks benefit from improved insulation and stormwater control.

• Green podium slabs & landscape decks

Common in mixed-use developments and mall complexes.

System Compatibility

LOGICROOF V-GR integrates perfectly with:

• Geotextiles
  
  

• Root barriers (when required)
  
  

• Drainage boards
  
  

• Soil/vegetation layers
  
  

• Irrigation systems
  
  

• Thermal insulation systems (XPS)
  
  

Its formulation ensures reliable sealing even when system layers shift due to temperature or moisture.

Environmental & Energy Benefits for India

Green roofs with LOGICROOF V-GR offer measurable advantages:

Lower Heat Absorption

Reduces indoor temperature — important for Indian cities with high rooftop heat loads.

Stormwater Management

Helps reduce drainage stress during monsoons.

 Improved Urban Air Quality

Vegetation absorbs pollutants and CO₂.

Sustainability & LEED Credits

Supports green building certification goals.
