Description Technical features and measures Related documentation

GLASDAN 30 AP ELAST. (7,5 M) is a waterproofing bituminous sheet with non self-protected surface of 3.0 kg/m², LBM-30-FV. Composed of a fibreglass reinforcement and covered on both sides with SBS modified bitumen mastic. Membrane with an upper surface finish of sand and a lower surface finish of polyethylene film.

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

1. Substrate should be dry and clean from grease, dirt, debris or any other contaminants.
2. Where applicable, prime surface with CURIDAN or bitumen primer+ in accordance with DANOSA instructions and allow to dry.
3. For field applications:

Roll the membrane into position, allowing for 80mm side overlaps and100mm head overlaps and cut to length. All overlaps and cross joints should be staggered by a minimum of 300mm.

Using a length of 100mm ø pipe (cut fractionally short of roll width) as an insert tube, roll back the membrane for a portion of the length (approximately 50%).

Heat activate the membrane by torching in a vee area between the roll and substrate.

Roll can be pushed forward by foot or by other suitable equipment. Apply downwards pressure when moving the roll to extrude a molten bead of bitumen from edges.

4. For detail applications

Place the membrane into position, allowing for 80mm side overlaps and100mm head overlaps and cut to length ensuring all overlaps and cross joints are staggered by a minimum of 300mm.

Heat activate the membrane by torching between the membrane and substrate.

Apply pressure and consolidate the bond to the substrate, ensuring a molten bead of bitumen is extruded from the edges.

Where falls apply, membrane rolls should be rolled up the slope so that water drains over and not into membrane overlaps.

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.
Do not use in single-layer system.
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).
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".
