Technical data sheet ASO®-Dichtband-120 Application Application 1. Apply the waterproofing material to both sides of the joint or wall transition to be bridged, at least 2 cm wider than the joint sealing tape that is used (e.g. using a 4–6 mm notched trowel). 2. Lay ASO®-Dichtband-120 in the fresh layer. 3. For structural movement joints, ASO®-Dichtband-120 is inserted into the joint and the fresh layer in the form of a loop. 4. For structural movement joints/movement joints, the pre-formed pieces are inserted into the joint and the fresh layer in the form of a loop. 5. Press in the joint sealing tape in the waterproofing layer meticulously without voids or wrinkles, using a flat trowel or pressure roller. 6. Joint-tape edges or connections to pre-formed pieces are applied with an overlap of at least 5 cm. 7. Bond joint-tape edges or connections with the waterproofing material without wrinkles, covering the whole area, and overcoat after. 8. If a liquid waterproofing membrane is used, apply the second layer of waterproofing membrane on top of the connecting waterproofing tape.
Storage conditions Storage Cool, dry, protected from sunlight. Min. 36 months in the original canister.
Emission behaviour / building certification systems Very low emissions in accordance with GEV-EMICODE, which normally results in positive evaluations within the scope of building certification systems in accordance with DGNB, LEED, BREEAM, HQE. Maximum quality level 4, line 8 in accordance with DGNB criteria "ENV 1.2 Risks to the local environment".
Notes Joints that are secured with ASO®-Dichtband-120 must be adequately protected against mechanical damage! ASO®-Dichtband-120 may not be glued or overcoated afterwards with products containing solvents. Border, field, building separation and movement joints should be carried over to or installed at the designated location; suitable means (e.g. edge strips) should be used to detach them!
Relevant regulations Planning, inspection of substrates and building site circumstances, laying, grouting and subsequent care of the work must be done in accordance with the relevant DIN standards and recognised rules of technology (e.g. the ZDB Data sheets of the Zentralverband Deutsches Baugewerbe e.V.(German construction Association) in the latest version.
