Standard product features

Separation layer:

- Bauder PE Foil Separation Layer:

(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 150mm 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: 4m.
  • Roll length: 50m
  • Thickness: ca. 0.2mm.
  • Weight (saturated): 0.19kg/m².
  • Material: Polyethylene foil manufactured from recycled granules

Board fill/Bedding layer (supplied by others):

Screed by others.

Type: As specified by the landscape designer/architect.

Extent: To designated areas beneath concrete paving – See landscape designers/architect’s plan.

Installation: Apply directly into the profiled cups of the specified drainage board, spread evenly and then additionally to the required finished depth. Provision should be made for containing the bedding screed layer at all abutments to ensure that material does not drop or leech into the area beneath the drainage layer and wash through to the outlets i.e. bedded concrete abutment kerbs or similar. The waterproofing should be isolated from any direct contact with the screed.

If the roof deck is level, it is advisable to create the falls within the bedding layer, so rainwater run-off is directed to the outlets/drainage point.

Paving / Block Paving (supplied by others):

Paving installation: Slabs/suitable pavers to be laid in suitable bedding screed, as specified by the landscape designer/architect and strictly in accordance with their specific recommendations regarding the layout in keeping with the landscape design.

Setting out: Minimize cutting.

Joints: Grouted in accordance with the client’s requirements.

Slabs must be level and stable.

Product Options

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.

Drainage/Water storage layer:

- Bauder DSE20 Drainage and Protection Layer:

HDPE water storage and multi-directional drainage layer. Used on roofs 1-5° 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, 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.

  • Size: 1.06m x 2.36m (2.5m2).
  • Nominal wall thickness: 2 mm.
  • Depth: 20 mm.
  • Coverage: 2 m² (approximate).
