The waterproofing integrity of roof gardens and green roofs is critical to ensure permanent waterproofing below the growing medium. Root penetration can pose a significant risk to waterproofing systems without suitable root resistant membranes to prevent penetration of the waterproofing system.

Rootbar torch-on roofing capsheet is for use as a waterproofing  membrane on flat, sloping and completely flat roofs with limited access as a partially or fully bonded system and in gardens (intensive planting) on flat roofs and green roofs (extensive planting). The capsheet is impervious to water and, the Rootbar torch-on capsheet will adequately resist penetration of roots.

Used as the top layer in the two-layer Icopal Green Roof waterproofing system, this high performance torch-on roofing membrane combines:

• The elastomeric properties of SBS-modified bitumen with specially formulated root inhibitors.
• High quality polyester reinforcement for puncture resistance and dimensional stability.

When installed to Icopal’s specification and by an Icopal approved contractor, comprehensive insured guarantee cover for up to 20 years is available.
