 Advantages and Benefits

- Suitable for contact with food and drinking water, accredited by tests and thanks to the use of virgin and non recycled raw materials.
- Excellent resistance to tearing.
- High tensile strength.
- High puncture resistance.
- High dimensional stability.
- Very good resistance to: microorganisms; putrefaction; natural aging, weathering, UV radiation and swollen.
- Excellent flexibility.

- Improves performance in mechanically fastened sheets.
- Absorbs structural movements to resist the stresses.
- Presents a good protection against mechanical damage.
- Limit strains and tensions in the waterproofing membrane.
- Very high durability with respect to possible degradation caused due to chemical type.
- High adaptability to the different forms of support.

 Instruction for use

Substrate preparation:
- - The base support surface must be durable, uniform, smooth, be clean, dry and free from foreign bodies.
- As a separating layer or protective polyester geotextiles are used, type Danofelt PY 300 or higher

Placement waterproofing layer:
- DANOPOL H 1.2 DW can be welded by hot air or by chemical THF bonding (Tetrahydrofuran)

 Indications and Important Recommendations

- In case of drinking water tanks waterproofing, the estimated durability of the waterproofing sheet will be conditioned, at any time, by the correct water maintenance by end users.
-Incompatible materials in direct contact with DANOPOL DW HS 1.2 BIO waterproofing membrane: Bituminous products, XPS, TPO/FPO, EPS, EPDM, PU. DANOFELT PY300 or higher must be placed between both materiales to avoid chemical incompatibility or smooth any coarse surface.
- Make sure the chemical compatibility of DANOPOL DW HS 1.2 BIO with other materials.
- Weldability and weld quality depends on atmospheric conditions (temperature, humidity), welding conditions (temperature, velocity, pressure, cleanliness) and by the state of the membrane surface (cleanliness, humidity). Therefore must meet the hot air machine for the correct assembling
- Once the surface has been cooled, a strict welding control should be made using a blunt needle.

 Handling, Storage and Conservation

- DANOPOL DW HS 1.2 BIO is not toxic or flammable.
- DANOPOL DW HS 1.2 BIO should be stored in a dry place protected from rain, sun, heat and low temperatures. It should remain in its original packaging, horizontal and parallel (never crossed) on a flat and smooth support.
- DANOPOL DW HS 1.2 BIO will be used as soon at it arrives at the building construction.
- DANOPOL DW HS 1.2 BIO is easy to cut in order to adapt it to the work's geometry.
- No waterproofing works should be performed when weather conditions may be harmful, particularly when it is snowing or there is snow or ice on the deck, neither when the roof is covered by raindrops, surface moisture > 8%, or strong wind.
- No waterproofing works should be performed when the ambient temperature is less than -5 º C for hot air welding.
- In all cases, please keep Health and Safety standards at work, and good construction practice.
