Description Technical features and measures Related documentation

GLASDAN 40 P ELAST. is a waterproofing bituminous sheet with non self-protected surface of 4.0 kg/m². Composed of a fibreglass reinforcement and covered on both sides with SBS modified bitumen mastic. A polyethylene film is used as anti-adherent material on both sides. Tested according to standard EN test methods.

Scope

Bottom or top sheet in two-layer membranes for waterproofing of roofs with heavy bonded protection.
Bottom or top sheet in two-layer membranes for waterproofing of heavy unbonded or floating roofs with heavy protection.
Bottom reinforcement in improved single-ply waterproofing membranes for roof waterproofing with heavy bonded protection.
Bottom reinforcement in improved single-ply waterproofing membranes for waterproofing of heavy unbonded or floating roofs with heavy protection).

Advantages & Benefits

Little thermal variation.
High dimensional stability.
The sheet, being made of a bitumen mastic modified with SBS-type elastomeric polymers, substantially improves other bituminous mastics, providing much better performance in terms of reaction at high and low temperatures, elasticity and resistance to ageing, which leads to greater durability of the sheet and greater safety of the waterproofing membrane.
Limits deformations.
Limits stresses in the waterproofing membrane.
Very good performance in multilayer systems with hot asphalt.
Allows for adaptation to any type of geometry.
Allows for working with molten asphalt.

Instruction for Use

The POLYDAN 50/GP ELAST. GREEN GARDEN (5 m) is laid over the first layer in the same direction, and fully bonded. The top layer is installed with side laps a minimum of 60 mm and end laps 100 mm wide. Laps between the membrane and any base sheets should be offset by a minimum of 300 mm. Bonding is achieved by melting the lower surface by torching and pressing the membrane down. Care must be taken not to overheat the membrane. It is imperative that the drainage system of the green roof or roof garden is designed correctly, and provision is made for access for maintenance purposes. Inspection of the drains should be carried out regularly to avoid waterlogging of the garden and the subsequent increase in dead weight load. Where there is a run-off from a large sill or gully onto the roof surface, the build-up of silt may allow the germination of seeds, therefore this type of detail should be avoided. Any growth occurring will be restricted and will not normally affect the performance of the roof and will be no worse than that occurring on normal flat roofs.

Indications and Important Recommendations

In case of new construction and renovation, possible chemical incompatibilities with APP plastomer-modified bitumen sheets shall be taken into account.
In case of refurbishment, chemical incompatibilities with old waterproofing systems consisting of PVC membranes, modified tar-based mastics or any other, shall be taken into account, and it may be necessary to remove them completely or to use suitable separating layers.
If it is necessary to adhere to metallic or slightly porous elements, a bituminous primer (IMPRIDAN 100) shall be applied to the entire surface to be welded beforehand.
This product may form part of a waterproofing system, so all the documents referred to in the Danosa Solutions Manual must be taken into account, as well as all the regulations and legislation that must be complied with in this respect.
There is no chemical incompatibility between the Danosa range of SBS elastomeric bitumen and APP plastomeric bitumen membranes.
Not suitable as cap sheet on green roofs; use GARDEN variant.
Possible incompatibility between thermal insulation and waterproofing shall be checked.
A separating layer (DANOFELT or DANODREN) shall be laid before laying the heavy protection (paving, gravel, topsoil, etc).
Special attention must be paid to the execution of the singular points, such as parapets (meetings with vertical and emergent elements), drains, expansion joints, etc.
Polyurethane foam shall not be sprayed directly on top of the waterproofing without the use of a suitable separating layer (geotextiles, mortar layers, polyethylene film, etc).
If expansion that could affect the sheet is expected, a geotextile separating layer (Danofelt PY 200) shall be used between the sheet and the extruded polystyrene insulation panels, so that each product expands independently.
NOTE: For more information on the Danosa systems in which this product is used, please see the document "Waterproofing Solutions".
