Green Roofs & Planters: Waterproofing and Root Barrier Protection
A green roof, roof garden or built-in planter: success depends on the layers beneath the soil. The two risks are always the same: roots seeking out every joint in the waterproofing and water pooling. Here you will find complete layer-by-layer breakdowns for extensive and intensive green roofs and for balcony planters, as well as a guide to selecting root-barrier protection: a certified natural barrier in accordance with CEN/TS 14416, bituminous membranes with a root-barrier additive, or liquid-applied coatings. The waterproofing is complemented by dimpled drainage membranes with geotextile, perforated pipes, parapet details and vertical root barriers for foundations and utility networks. ARGYNET specifies the entire system and calculates loads and quantities on a project-by-project basis.

Root protection: when to use a physical barrier, and when a chemical inhibitor?
Roots do not break through the waterproofing — they find a way through it. A physical barrier or a chemical inhibitor: they fail in opposite ways, and that is w

A green roof is built once. The sequence of works, the watertightness test before adding soil, and the details that cannot be rectified afterwards.

Installation of a root-barrier membrane
The vertical barrier does not kill the root — it diverts it. Trench depth, 2–5 cm overhang, overlaps and the side facing the roots.
