Roof - Stone Overlay Finish

Novaflex / Polibit with Stone Aggregate Overlay is a double-sheet roof waterproofing membrane system.

Two polyester-reinforced membranes – one plain, the other chip-finished – are overlaid using a torch-on application method to create a high performance base waterproofing layer. The base is overlaid with a drainage medium, followed by aggregate, to create an attractive and long-lasting finish.

Drainage:

A proprietary drainage cell/sheet system, usually of plastic composition, must be installed over the applied membrane system and followed by a geotextile cloth overlay. Rounded river stones and/or stone aggregate are then manually placed on top of the geotextile cloth.

In the case of aggregate, the drainage medium must be applied up against all upstands to the anticipated height of the laid aggregate.

Proprietary perforated retainers and/or concrete pavers on Jaydex corner supports must be installed around all drainage outlets and along internal gutter edge lines.

Limitations of use:

Not suitable for rooftop gardens.
