DANOPOL HSF 1.5 is a synthetic PVC plasticised membrane, reinforced with a polyester net carrier, and a 300 g geotextile fleece backing. It has a 6 cm overlap free of the geotextile on the right longitudinal side, allowing overlaying and welding to the adjacent sheet. Intended for flat roof applications only.
Scope
- Channel waterproofing (EN 13362).
- Mechanically fastened roof waterproofing systems (EN 13956).
- Waterproofing of reservoirs and dams (EN 13361).
- Waterproofing against fluids in the construction of tunnels and underground structures (EN 13491).
Advantages & Benefits
- Good absorption of structural movements.
- High tensile strength.
- High resistance to piercing.
- Hot air welded: Flame-free system
- Great elasticity.
- High resistance to tearing.
- Allows for adaptation to any type of geometry.
- UV resistant.
- System bonded to the support by a projected adhesive.
Support
- Profiled metal decks.
- Insulation panels.*
- Concrete subsrates.
- Timber.
- Mortar subsrates.
Instruction for Use
- The membrane should not be installed in adverse weather conditions. It must not be laid in rain, snow, or heavy fog, nor if the temperature falls below 5ºC, unless precautions against condensation have been taken.
- Do not apply on wet or frozen surfaces.
- Not suitable for pitched roofs over 5° (1:11) and/or vertical surfaces.
- The membrane layers must always be installed with staggered overlaps and in such a manner that the laps fall in the direction toward the outlets.
- The sheets shall be laid in such a way that no transverse overlap of each row is aligned with any of those of the adjoining rows.
- The joint between sheets shall be made by thermoplastic hot-air welding.
- Attachment of DANOPOL HSF membrane may be achieved by full bonding, or loose laid (ballasted) with guidance from DANOSA technical services; the choice should depend upon the type of substrate and the required resistance to wind uplift pressure.
For single layer application direct to deck:Â - The surface of the base substrate shall be resistant, uniform, smooth, clean, dry, and free of foreign bodies.
- Before laying the waterproofing membrane, apply Fleecebond Adhesive to the entire surface of the substrate in accordance with the applicable datasheet instructions.
- The membrane must terminate a minimum of 15cm above the surface of the finished roof surface level.
- Finished edges must be terminated in accordance with DANOSA UK recommendations (see standard details).
For adhered applications:- Roll the DANOPOL or DANOPOL+ HSF 1.5 into position, allowing for 50mm side overlaps and 50mm head overlaps and cut to length. At perimeters and details, allow an additional 50mm to allow for mechanical restraint.
- Apply DANOSA UK FLEECEBOND Adhesive (see DANOSA UK Technical Datasheet) to the substrate only in accordance with DANOSA UK instructions.
- Position the next roll of DANOPOL or DANOPOL+ HSF 1.5, allowing for overlaps as previous, and seal with a minimum 30-40mm hot-air weld in accordance with DANOSA UK instructions.
- The overlaps shall be at least 4cm 5 cm. and the welding of the lower sheet with the upper one shall be at least 4 cm. In the case of thermoplastic welding, immediately after welding, the joint shall be pressed with a roller, thus ensuring a homogeneous joint. To check the joints, a physical check shall be made using a blunt metal needle (with a rounded tip with a radius between 1mm and 3mm), passing it along the edge of the joint.
- No more than three sheets shall be joined at a single point.
- In T-joints (three sheets intersecting at one point), the bottom sheet shall be chamfered to prevent capillary leakage or be reworked with the hot air welder.
- The apex of the angle formed by the transverse and longitudinal edges of the upper part shall be cut in the form of a curve.
- For the transverse overlapping of sheets and if profiles are to be attached to the sheet, they shall be covered by welding 21cm DANOPOL HS 1.5 COVERSTRIP strips in the same colour.
For system application:
- In the case of thermal insulation, the boards must be adhered to the substrate using DANOTHERM with a gap of no more than 1 mm between boards.
- The surface of the base substrate shall be resistant, uniform, smooth, clean, dry, and free of foreign bodies.
- Before laying the waterproofing membrane, apply Fleecebond Adhesive to the entire surface of the substrate or insulation board in accordance with the applicable datasheet instructions.
- Mount the film on the vertical surface without the need for adhesive.
Handling, storage and preservation
- The product must be stored in a dry place protected from rain, sun, heat and low temperatures.
- The product will be used on a first-come, first-served basis.
- This product is not toxic or flammable.
- Easy to cut to adapt the dimensions to the work.
- Waterproofing work must not be carried out when weather conditions may be detrimental, in particular when it is snowing or there is snow or ice on the roof, when it is raining or the roof is wet, surface dampness >8% according to NTE QAT, or when a strong wind is blowing.
- No welding work should be carried out when the ambient temperature is lower than -5ºC for hot air welding, nor lower than + 5ºC for welding with THF or with Adhesives.
- It shall be kept in its original packaging, in a horizontal position and all rolls parallel (never crossed), on a flat and smooth support.
