Green roofs (or terrace gardens) are becoming immensely popular in modern urban architecture. They provide outstanding thermal insulation and aesthetic beauty. However, introducing soil, constant moisture, and aggressive plant roots onto a concrete roof is inherently risky.

The Threat of Root Penetration

Plant roots are relentless. As they search for water, they will naturally burrow into the microscopic pores of standard waterproofing membranes, eventually breaching the concrete slab itself.

Anti-Root Waterproofing Systems

For any green roof project, Sichern Engineering strictly recommends the use of Root-Resistant Waterproofing Membranes.

These advanced polymer-modified bitumen membranes are chemically treated to repel roots, forcing them to grow laterally rather than downwards. Installed via heat welding, they form a thick, impenetrable protective layer.

This is followed by specialized drainage boards and geotextile filters to prevent the soil from clogging the drains. Build your terrace garden with absolute confidence by consulting our specialists today.
