Drainage layer | BauderGREEN DSE 40 drainage board.Guidance for specification option: PE-HD water storage and multi-directional drainage layer. Used on roofs 0–5° finished falls. Loose laid (open profile cup up) on to the Protection Layer (or WFRL on inverted roofs) over completed waterproofing to provide continuous drainage within hard and soft landscaping. It is primarily used where the load is moderate to high, such as extensive and intensive green roofs. Its compressive strength makes it suitable beneath paving laid on sand/ cement or gravel bedding or within planter beds. Boards are to be interlocked by a minimum of one profile cup and all board joints staggered. The ‘X’ stamped impression on the highpoint of the cup moulding indicates where boards overlap. Cut to fit closely around penetrations and outlets.
The drainage/ water storage board also provides a suitable base surface for building concrete or brick kerbs/ walls. The specified infill haunching should be installed over the board to the required depth of cover, poured directly into the profile cup of the board. These should be constructed to provide an adequate support for the raised masonry planters. BauderGREEN DSE 60 drainage board.Guidance for specification option: PE-HD water storage and multi-directional drainage layer. Used on roofs 0–5° finished falls. Loose laid (open cups down) on to the Protection Layer (or WFRL on inverted roofs) over completed waterproofing to provide continuous drainage within hard and soft landscaping. Provides a pressure resistant stable base for high loads or support for roof mounted equipment without compression to the drainage capacity. If DSE60 is filled with Bauder Mineral Drain, it provides a robust temporary finish able to accept site traffic, including vehicles. Boards are to be tightly overlapped at the edges and staggered. Cut to fit closely around penetrations and outlets.
The drainage/ water storage board also provides a suitable base surface for building concrete or brick kerbs/ walls. The specified infill haunching should be installed over the board to the required depth of cover, poured directly into the cups of board. These could be constructed to separate landscaping types (soft/ hard) or to provide an adequate support for the raised masonry planters. BauderGREEN WSP 50 reservoir board and BauderGREEN WSP 75 reservoir board.Guidance for specification option: Water storage and multi-directional drainage layer. Used on roofs 0–25° finished falls (the only suitable Drainage and Protection layers for slopes 6° upwards). Boards laid over the entire area to provide continuous drainage and increased water capacity for the vegetation. Loose laid (open cups up) on to the Protection Layer (or WFRL on inverted roofs) over completed waterproofing ensuring that the rebated boards are properly interlocked to provide adequate anchorage prior to the soil being laid. The board cups can be filled with water to provide temporary loading against wind uplift prior to installing the remaining landscaping elements in accordance with the specification. In the event of any confusion concerning this item, Bauder Ltd should be contacted so that advice may be given. Cut to fit closely around penetrations and outlets. Roof slopes 6° upwards, a parapet wall or restraint kerb must be provided to support the water storage/ drainage board at the base of the slope. This should be included within the deck construction and reference made within the waterproofing specification also. This in turn will restrain and stabilize the landscaping against imposed shear load forces.

Filter membrane | BauderGREEN FV 125 filter fleece.Guidance for specification option: Fine mesh PP geotextile used in conjunction with Bauder substrates. BauderGREEN FV 125 filter fleece is designed to separate and contain Bauder substrates from the drainage element of the green roof system (for slopes 0–5°). It prevents fine material from being washed out of the substrate layer. Loose laid over the drainage layer. The fleece should be taken up the sides of the substrate between the substrate and drainage trim or pebble margin. Fleece joints should be overlapped 150 mm. Fleece should not be taken over the top of drainage outlets. Upstands (soft landscaping): Extend up, between vegetation barrier and growing medium and trim flush with finished surface level. Upstands (Hard landscaping): Extend to top of perimeter abutments and trim flush just below finished surface level. A filter layer is not used over reservoir board on slopes 6° or above, where the reservoir board is directly filled with substrate growing medium. However, a separate strip of BauderGREEN FV 125 filter fleece must still be used to separate the growing medium from the vegetation barrier at perimeter abutments and around pipe protrusions, outlet inspection chambers etc. dressed up all upstands and around all protrusions to at least flush with the finished surface level. At abutments the BauderGREEN FV 125 filter fleece must be used to separate the vegetation/ drainage barrier and substrate growing medium by extending it 500 mm beneath the reservoir board and then bringing it up between these two items.

Planting systems | |
Planting medium | BauderGREEN SUB-IM UK intensive substrate.Guidance for specification option: Lightweight, free draining substrates designed as a growing medium for a range of different plant species. This FLL/ GRO compliant substrate provides a free draining, growing medium for intensive green roof systems. Additionally, it provides aeration qualities with some inherent water retention.
Normally installed above a Filter Fleece and drainage board product. Roofs pitched 6° and above, apply the substrate growing medium directly into the open cup of the Reservoir board and then build up to the depth specified. Substrates are raked out to give an even coverage of the required depth after settlement. Handle in the driest condition possible. Do not handle or install when wet or frozen. Start by applying two equal layers, building up to the required maximum depth. Gently firm each layer before spreading the next. Allowance should be made for any settlement that may occur. It is recommended that ‘measuring stick’ markers of the required depth be used around the roof area to ensure that a minimum acceptable thickness of growing medium is achieved. Depending on size and access of the project the ‘substrate’ can be supplied by various methods i.e. tipper, big bags, or sacks. Prior to costing this element of the installation, the ‘Bauder Approved Contractor’ must contact Bauder Ltd so that they may advise on the best solution on any specific contract. When the substrate is to receive a turf or grass seed finish, an additional dressing of organic compost should be applied to the surface of the Intensive Substrate at the rate of 10 L/m², which is equivalent to a depth of 10 mm. Important note regarding alternative substrates: If alternative substrates are required (e.g. topsoil), Bauder does not take any responsibility for the performance of such substrates supplied from an alternative source. We recommend that alternative substrates should be covered by a technical data sheet and certified in writing as suitable to support the system and plants specified. Saturated weight loadings must be provided directly from the supplier of the substrate and should be the subject to a structural engineer’s approval. Manufacturer guidanceRecycled crushed brick, expanded clay, shale, composted pine bark. Normal minimum depth for intensive soft landscaping – from ca. 200 mm. Depth to be confirmed by client/ landscape architect. |
