Description

Intensive roof system, with hard landscaping for heavily trafficked access. This type of sub-bedding layer allows for installation of various surface finishes, such as, MUGA, resin bound, artificial grass and play top surface. When the roof structure allows, the hard-landscaping finishes can be designed to allow for driveway access for slow-moving vehicles, such as cars and cherry pickers.

Key features:

  • Designed with a compressive strength of up to 1000 kN/m² when using Bauder DSE40/ DSE60 Drainage and Protection Layer.
  • Creates low-maintenance, accessible spaces.
  • Versatile visual finish.
  • Finished paved surface can support free-standing planter-held vegetation.

Benefits:

  • Assists in maximizing the building's potential.
  • Creates a moveable scheme if free-standing planters are utilized.
  • Low maintenance.

Suitable waterproofing systems:

  • Bauder Total Green Roof System Roof Covering System.
  • Bauder Total Roof System Roof Covering System.
  • Bauderflex Green Roof System.
  • Bauderflex Roof System.
  • Bauder LiquiTEC Cold Liquid Applied Roof System.
  • Bauder Bakor790-11 Hot Melt Rubberized Bitumen Roof Coating System.

Suitable finishes:

  • Paving with 2–5 mm crushed gravel bedding layer (supplied by others).
  • Resin bound/ bonded surfacing (supplied and installed by others).

Product Options

Slip layer:

- Bauder PE Foil Separation Layer:

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

All laps are 150 mm, and roll sides should join between layers. Upstands should be extended to the top of the growing medium. Sufficient foil must be allowed to enable it to be taken up at all upstand and edge details prior to installation of the protection layer.

  • Material: polyethylene foil manufactured from recycled granules.
  • Roll size 4 x 50 m (w x l).
  • Thickness: 0.2 mm (approximate).
  • Weight (saturated): 0.19 kg/m².

Protection layer:

- Bauder FSM 1100 Protection Mat:

Heavy-duty protection layer constructed from polyester and polypropylene fibres. Laid on the completed waterproofing to protect the completed waterproofing from damage (not required for inverted roofs).

Usually 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-sealing the two fleece sheets together. Sufficient protection fleece must be allowed so that it may be installed to all abutment upstands and edge details, in accordance with Bauder instructions.

  • Material: polyester and polypropylene fibre mix.
  • Size: 2 x 15 m (w x l).
  • Thickness: 8 mm.
  • Coverage: 30 m².
  • Weight (saturated): 7.16 kg/m².

- Bauder Pro-Mat Protection Mat:

Heavy-duty protection layer, constructed from recycled shredded tyres. Laid on the completed waterproofing to protect the completed waterproofing from damage (not required for inverted roofs, and not for use with PVC waterproof membranes).

Usually installed under the entire green roof area, but kept clear of all outlets and drainage trims. Usually installed to provide access over waterproofing in heavily trafficked areas. Pro-mat should be lapped by 150 mm at all joints.

Loose-laid. Where landscaping installation is not imminent, loose laps should be taped with gaffer tape to eliminate the trip hazard. Sufficient protection fleece must be allowed so that it may be installed to all abutment upstands and edge details, in accordance with the Bauder instructions.

  • Material: 100% recycled shredded rubber.
  • Size: 1.25 x 10 m (w x l).
  • Thickness: 6 mm.
  • Coverage: 12.5 m².
  • Weight (saturated/ dry): 4.3 kg/m².

Drainage layer:

- Bauder DSE40 Drainage and Protection Layer:

High-density polyethylene (HDPE) water storage and multidirectional drainage layer. Used on roofs with 0–5° finished falls. Loose-laid (open profile cup up) on to the protection layer (or water flow-reducing layer, 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, such as extensive green roofs, beneath paving laid on sand/ cement or gravel bedding, or within planter beds.

Boards should be interlocked by a minimum of one profile cup and all board joints staggered. Cut to fit closely around penetrations and outlets.

  • Material: 100% recycled, high-density polyethylene.
  • Size: 1.04 x 2.03 m (2.1 m²).
  • Nominal wall thickness: 2 mm.
  • Depth: 40 mm.
  • Coverage: 2 m² (approximate).
  • Water storage: 13.5 L.
  • Weight (saturated): 15.3 kg/m².

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.

- Bauder DSE60 Drainage and Protection Layer:

High-density polyethylene (HDPE) water storage and multidirectional drainage layer. Used on roofs with 0–5° finished falls. Loose-laid (open cups down) on to the protection layer (or water flow-reducing layer, 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 should be tightly overlapped at the edges and staggered. Cut to fit closely around penetrations and outlets.

  • Material: 100% recycled, high-density polyethylene.
  • Size: 1.975 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.

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.

Board Fill:

- Bauder Mineral Drain:

Lightweight, single-size crushed limestone used in Bauder DSE60 Drainage and Protection Layer. This substrate provides an ecological drainage method for green roof systems. Additionally, it provides aeration qualities with some inherent water retention. Usually installed directly into the drainage board to give an even coverage of the required depth.

  • Material: single-size crushed limestone.
  • Weight (saturated): ≤1,375 kg/m³.
  • Water storage: 8–10% by volume.
  • pH value: 7–9.

- DTP Type 1/ DTP Type 3 compacted sub-base (supplied and installed by others).

Installed directly into the Bauder Drainage and Protection Layer to a minimum depth of 150 mm.
