Inspection Chambers, Conduits, Channels and Gutters

Inspection Chambers

In accordance with current green roof regulations, drainage outlets must be accessible at all times. For this reason, inspection chambers should be used above the drainage outlets. Depending on height, our inspection chambers can be used for both extensive and intensive green roof structures.

Optigrün Combi Inspection Chamber TKS Plus is a control shaft for use as roof outlet inspection; includes base plate and cover. Extendable in 100 mm increments. Combinable with Triangle Water Discharge Profiles.

Optigrün Inspection Chamber TAR 250 to keep roof drainage outlets free with four connection options for TAR 80/250 or TAR 120/250.

Optigrün Edge Inspection Chamber RKS 80 for use on greened or gravelled roof areas above drains on edge areas directly before any ascending structural components.

Optigrün Triangle Maxi Inspection Chamber TMK suitable for negative pressure drainage.

Inspection chamber for use on greened or gravelled roof areas above drains in edge areas directly before any ascending structural components.

Special version of the Optigrün Triangle Maxi Inspection Chamber TMK with perforated intermediate floor to guide excess water from higher roof areas.

Optigrün Polymer Concrete Inspection Chamber PBK to be used as a drainage unit to guide surface water, corresponding to the respective requirements in the suitable composition, on stable substrates (e.g. underground garage decks) with a sufficiently high layer thickness.

As a load distribution panel for the Optigrün system solution "Public Roof with Inspection Chamber"; Including 0.5 m² Optigrün Water Retention Box WRB 85v with corresponding cut-out.

Conduits and channels

Elements for linear drainage and to support convey-ance of excess water from drainage and substrate layers, as well as green and gravelled rooftops.

Due to the different requirements and operational demands, we offer conduits and ducts made of recycled plastic, aluminium, steel and stainless steel. Our conduits, ducts and inspection chambers are adapted to one another, and work great in combination.

Optigrün Triangle Water Conduit WLP Plus. As linear drainage to support the guidance of excess water from drainage and substrate layers. The profiles can be fitted together using a simple click fastening system to form endless lengths.

Optigrün Triangle Collection Channel TSK as inear drainage to support the guidance of excess water from drainage and substrate layers, particularly in drainage valleys for intensive green roofs with a higher weight.

Open gutter for the collection and linear guiding of excess water from greened or gravelled roof areas. The gutter construction is particularly suited to optimising the flow of water with negative pressure drainage systems on large roof areas.

Drainage gutters

The drainage gutters are suitable for all applications in which excess water needs to be drained quickly and in a targeted manner: terraces, façades and other rising components, as well as around the eaves of pitched roofs. Gutters are particularly crucial with barrier-free designs. They are made of galvanised steel or stainless steel and are available in various lengths, heights and cross-sections.

Optigrün Drainage Gutters and Terrace Grids to guide surface water from the floor surfaces into the roof drainage outlets, to drain water-guiding layers, to guide driving rain on facades, as a collection channel to drain greened roof areas and as a branch channel between downpipes and roof drainage outlets.
