BauderHARDSCAPE Roadway System, Impermeable Hard Landscaping

BauderGREEN FSM 1100 protection mat.

Guidance for specification option:

Heavy-duty protection layer constructed from polyester and polypropylene fibres. Laid on the Bauder PE Foil 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.

Sufficient protection fleece must be allowed for so that it may be installed to all abutment upstands and edge details, in accordance with the Bauder instructions. Extend to full height of the upstand and secure in place by using a lead or fabricated metal counter-flashing.

Should be trimmed well back from ALL outlets.

Openings in landscape restraint kerbs (where present – roof slopes above 5º), the protection layer should be cut away from the openings/ gaps to avoid impeding drainage.

• Width: 2 m.
• Length: 15 m
• Thickness: 8 mm.
• Coverage: 30 m².
• Weight (saturated): 7.16 kg/m².
• Material: Polyester and polypropylene fibre mix.

BauderGREEN PE 02 separation layer.

Guidance for specification option:

(Not required for inverted roofs).

Separation layer and slip layer to be rolled out loose over the completed waterproofing layer in two layers for Intensive landscaping. This product is only required for roofs with a fall between 0–3º (A slip layer is not necessary or advisable for slopes above 3º).

All laps to be 150 mm with care being taken to ensure that roll sides join between layers.

Upstands: Extend to top of growing medium. Sufficient foil must be allowed for to enable it to be taken up all upstand and edge details prior to installation of the protection layer.

• Roll width: 4 m.
• Roll length: 50 m
• Thickness: ca. 0.2 mm.
• Weight (saturated): 0.19 kg/m².
• Material: Polyethylene foil manufactured from recycled granules

BauderGREEN PE 02 slip layer.

Guidance for specification option:

0.2 mm separation and slip layer, polyethylene foil. Loose laid on the completed waterproofing in two layers. (NB: Not required for inverted roofs or roofs over 3°).

BauderGREEN DSE 40 drainage board.

Guidance for specification option:

Ideal for higher levels of trafficking.

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.

• Size: 1.04 x 2.03 m (2.1 m²).
• Nominal wall thickness: 2 mm.
• Depth: 40 mm.
• Coverage: 2 m² (approximate).
• Filling capacity: 21 L.
• Compressive strength: 80 kN/m² empty/ >1000 kN/m² aggregate filled.
• Weight (concrete filled): circa 44 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 DSE 60 drainage board.

Guidance for specification option:

Ideal for heavy trafficking and higher weight loads.

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.

• Size: 0.975 x 1.975 m (1.93 m²).
• Nominal wall thickness: 2 mm.
• Depth: 60 mm.
• Coverage: 1.9 m² (approximate).
• Water storage (when filled with Bauder Mineral Drain): 10–12 L.
• Filling capacity: 33 L/m².
• Compressive strength: 100 kN/m² empty/ >1000 kN/m² filled.
• Weight (saturated and filled with Bauder Mineral Drain): 51.9 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.
