RootGuard PVC Waterproofing Membrane

RootGuard PVC Waterproofing Membrane

RootGuard PVC Waterproofing Membrane is a high-performance polyvinyl chloride (PVC) waterproofing solution specifically engineered for green roofing systems, plaza decks, and underground structures requiring exceptional root penetration resistance. Combining advanced polymer technology with specialized root-resistant additives, this membrane provides reliable long-term waterproof protection while preventing root-induced damage to building structures.

As urban greening initiatives expand worldwide, the demand for reliable root-resistant waterproofing has never been higher. RootGuard delivers the perfect balance of flexibility, durability, and root resistance, making it the preferred choice for landscape architects, contractors, and building owners.

Key Advantages

1. Advanced Root Resistance Technology

RootGuard incorporates specialized chemical root-resistant agents that prevent root penetration without harming plant growth. Tested in accordance with EN 13948 and DIN 4062 standards, this membrane provides reliable long-term protection against aggressive root systems.

2. Superior Weather Resistance

Engineered to withstand extreme environmental conditions, RootGuard maintains its performance across a wide temperature range from -40°C to +80°C. Excellent UV resistance ensures durability during exposed installation periods.

3. High Tensile Strength & Flexibility

With exceptional tensile strength and elongation properties, RootGuard accommodates structural movement, thermal expansion, and contraction without cracking or delamination.

4. Chemical Resistance

Resistant to acids, alkalis, and a wide range of chemicals commonly found in soil and planting media, ensuring long-term stability in green roof environments.

5. Easy Installation

Available in wide sheet formats with overlapping seams that can be heat-welded using hot air or hot wedge equipment, creating homogenous, watertight connections. Suitable for both mechanical attachment and ballasted installation methods.

6. Long Service Life

Designed for durability, RootGuard provides reliable waterproofing protection for 25+ years when properly installed, reducing lifecycle costs and maintenance requirements.

Why Choose RootGuard for Green Roof Projects?

Protection Against Costly Repairs

Root penetration is one of the most common causes of green roof failure. Once roots penetrate the waterproofing layer, water infiltration leads to structural damage, mold growth, and expensive repairs. RootGuard eliminates this risk with proven root-resistant technology.

Environmentally Responsible

RootGuard is manufactured using sustainable processes and is 100% recyclable. By enabling green roof construction, it contributes to urban heat island reduction, stormwater management, and biodiversity enhancement.

Global Standards Compliance

Our membrane meets or exceeds international standards including:

  • EN 13948 – Root resistance testing

  • ASTM D4434 – PVC sheet roofing

  • ISO 9001 – Quality management

  • LEED v4 – Contribution to green building certification

FAQ – Frequently Asked Questions

Q: Can RootGuard be used with all types of green roofs?
A: Yes, RootGuard is suitable for extensive, semi-intensive, and intensive green roof systems.

Q: Does the root-resistant additive affect plant health?
A: No. The root-resistant agents create a physical barrier without releasing chemicals that could harm plant roots.

Q: What is the warranty period?
A: Standard warranty is 10 years, with extended warranties up to 20 years available for certified installers.

Q: Can RootGuard be recycled at the end of its service life?
A: Yes, PVC membranes are fully recyclable. We offer take-back programs for large projects.

Q: Is RootGuard compatible with bituminous waterproofing?
A: A separation layer is required when installing over bituminous materials to prevent plasticizer migration.
