Hot Melt Structural Waterproofing
In an inverted roof build-up, the waterproofing layer is positioned beneath a loose-laid surface finish — such as ballast or paving slabs — which helps shield it from direct exposure to environmental conditions. This configuration can contribute to the long-term performance of the system, subject to correct specification and installation.
Hot melt structural waterproofing is commonly used in this type of build-up. Where insulation is included, it is installed above the waterproofing layer and must be suitable for exposure to moisture and temperature variation. Closed-cell insulation materials such as cellular glass, XPS, and EPS are typically selected for this purpose.
To support effective drainage and maintain insulation performance, a Water Flow Reduction Layer (WFRL) should be installed in accordance with project-specific design and manufacturer guidance.
