Waterproofing: Above Ground, Roof Tops, Protected Membrane Roof (PMR)

Protected Membrane Roof systems invert the traditional roof build-up by placing the waterproofing layer directly onto the structural slab, with insulation and overburden installed above. This configuration shields the membrane from UV exposure, thermal cycling, and mechanical damage. Dramatically improving long-term durability and reducing maintenance risk.

Envirosystems’ fully bonded membrane systems are ideally suited to PMR applications. By adhering directly to the concrete substrate, they eliminate the potential for lateral water migration beneath the membrane and significantly reduce the risk of concealed moisture tracking. A critical consideration in high-value commercial and infrastructure projects.

In large rooftop environments such as data centres, plant roofs, podium decks, and industrial buildings, protected membrane rooftops offers a practical and cost-effective solution. It reduces surface wear, simplifies installation logistics, and allows easier access for future inspection or reconfiguration compared to fixed topping systems.
