BauderGREEN FSM 600 protection mat.

Guidance for specification option:

Heavy duty protection layer made from polyester and polypropylene fibres. Laid on the completed waterproofing to protect the completed waterproofing from damage (not required for inverted roofs). Normally installed under the entire green roof area but kept clear of all outlets and drainage trims. FSM mats should be lapped by 150 mm at all joints. Loose laid. Laps to be sealed by lightly heating overlap area with a propane gas torch/ hot air welding gun to melt the polypropylene fibres and then press seal the two fleece sheets together.

BauderSOLAR G LIGHT BioSolar photovoltaic mounting system.

Guidance for specification option:

PE-HD integrated solar PV mounting system specifically for Bauder biodiverse or extensive greenroofs. Used on roofs 0–5° finished falls. Loose laid (open cups up) on to the Protection Layer (or WFRL on inverted roofs) over completed waterproofing.

BauderSOLAR G LIGHT should be used in conjunction with BauderGREEN Flora 3 Seed Mix, BioSOLAR and shade tolerant mix which contains both drought and shade tolerant herb and wildflower species and is suitable for roofs with a fall of up to 5°. BauderSOLAR Anchor boards (2 x 1 m) must be ballasted using Bauder substrate growing medium, applied above the filter fleece and then built up to a minimum depth of circa 100 mm. Allowance should be made for any settlement that may occur. Please see the project specific BauderSOLAR G LIGHT technical report for further information and required substrate depth.

Weight: 156 kg/m². (Includes weight of solar module and saturated Bauder Biodiverse green roof based on substrate depth 130 mm).

PV module specification – refer to NBS Engineering services Section V14, clauses 310 and 315 and the corresponding BauderSOLAR G LIGHT technical report for further information on scheme design or BauderSOLAR G LIGHT installation guidelines for further information on installation method. BauderSOLAR G LIGHT is designed to be installed by a Bauder approved and trained contractor only. The number of mounts and fixings required will vary from project to project. Please contact manufacturer for a project specific technical report for further information. Windload and snowload calculations will also be provided on a project specific basis and will determine ballast requirements and substrate depths.

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 butted up against the BauderSOLAR G LIGHT. BauderGREEN DSE 40 to DSE 40 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.

• Size: 1.04 x 2.03 m (2.1 m²).
• Nominal thickness: 2 mm
• Depth: 40 mm.
• Coverage: 2 m² (approximately).
• Water storage: 13.5 L.
• Filling capacity: 21 L.
• Compressive strength: 80 kN/m² empty/ >1000 kN/m² filled.
• Weight (saturated): 15.3 kg/m².
• Material: 100% recycled high-density polyethylene.

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 WSP 75 / 50 reservoir board.

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. For use in DSE40 areas only.

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.

• Weight (saturated): 0.125 kg/m².
• Pore size: 0.13 mm.
• Thickness: 1 mm.
• Roll size: 1 x 100 m/ 2 x 100 m.
• Coverage: 100 m²/ 200 m².
• Water storage: None.
• Material: Polypropylene fleece.

BauderGREEN SUB-BM UK biodiverse substrate.

Guidance for specification option:

Recycled crushed brick, expanded clay, shale, composted pine bark. Depth for BauderSOLAR G LIGHT areas is dependent on the ballasting requirements following windload calculation. Depth to DSE 40 areas, minimum 100 mm.

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 biodiverse green roof systems. Additionally, it provides aeration qualities with some inherent water retention.

• Material: Recycled crushed brick, expanded clay, shale, composted pine bark.
• Maximum Weight (saturated): ≤1200 kg/m³.
• Typical supply weight: c. 950 kg/m³.
• Water storage (by volume): 35%.
• pH value: 6–8.5.
• Bulk bag size: 1.25 m³.
• Small bag size: 25 L.

Applied directly into the profile cups of the Bauder SOLAR Anchor Boards.

Installed above the BauderGREEN FV 125 filter fleece in Bauder DSE40 Drainage and Protection Layer areas.

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.

Important note regarding alternative substrates:

Alternative substrates are not recommended for Bauder supplied planting.
