weber.tec Superflex 100 S

Drying time:
approx. 2 - 3 days

Storage:
The product can be stored for at least 12 months in its original unopened packaging if kept dry, cool and frost-free. Frost destroys the bitumen component. After thawing, it is not allowed to use it.

Fields of application

weber.tec Superflex 100 S is used for the external waterproofing of masonry and concrete below ground level for earth-contacting basement walls, concrete floor slabs, lean concrete (i.e. beneath floor concrete slab), foundations, ceiling slabs of car parking decks in cases of ground damp, non-pressure and pressure water.
Also, convenient for the intermediate waterproofing of wet-duty rooms, not-inhabited balconies and terraces under floor screed.
In addition, for spot-bonding or full-surface bonding of extruded polystyrene rigid-foam boards used as protective, drainage or perimeter insulation boards (depending on the specific use) on the pre-said building parts.
For outdoors.

Main features

• solvent-free, hence environment-friendly
• highly flexible and crack-bridging
• high dry residue ≥ 85%
• a 1.2 mm thick wet layer provides approx. a 1.0 mm thick dry layer
• quickly resistant to rain after 2.5 - 3 hours at 4 mm layer thickness
• suitable for any mineral substrates; no cement render is necessary on masonry
• resistant to ageing, to water attacking concrete up to the level "highly corrosive" in accordance with DIN 4030 (up to 3.000 mg sulphate per liter of water) and also to seawater
• resistant to thawing salts and freeze after full drying
• radon gas-tight
• sprayable with peristaltic pump and screw pump technology, e.g. Wagner PC 1030 with air support

General notes

• Limits of use: do not use for bonding foam glass insulation boards.
• All characteristics mentioned in this data sheet are given for a temperature of +20 °C, without draft and a relative rate of humidity of 50%.
• In the case of pressure water steel-reinforced concrete must satisfy the national standards (EN 206); if not issued and if necessary, refer to DIN 1045.
• In case of sunshine, carry out waterproofing works in shadow or in the morning or evening hours.
• Do not bond protective boards or insulation boards and do not fill the excavation pit until the material has completely dried.
• Prior to backfilling the excavation pit use the fleece-lined drainage and protection foil weber.sys 983 over the basement walls in order to protect the waterproofing system.
• Follow the national standards and/or guidelines; if not issued, and if requested, refer to the norm DIN 18533 “Waterproofing of Ground-contacting Building Structures”, the “Guideline for Planning and Execution of Waterproofing Works with Polymer-Modified Bitumen Coatings (PMBC)” (4th edition, Dec. 2018, issued by the German Construction Chemicals Association) and the WTA leaflet “Retrospective Waterproofing of Ground-Contacting Structures”.
• In the case of waterproofing water-impermeable concrete structures in the areas of working joints and butt joints of pre-cast concrete elements, comply with the national guideline (if existing) relating to such concrete structures.

Special notes

• Do not add any foreign substances during mixing and application.
• Refer to our comprehensive document “General Guidelines for Waterproofing Works with Bitumen Thick Coatings” for full information related to important issues like assessment of water load, thickness control, and all execution details.
• The consumption figures given in this document will increase if the applicator lacks experience. In addition, the figure for the scratch layer – 1.0-1.5 kg/m² depending on the substrate roughness – must be added on top.
• Remove any hardened material residues on the packaging edges before mixing.
• The spray application should be carried out in several layers (max. 2 mm per layer), in order to achieve surfaces with as few pores as possible.
