Geotextiles
DANOFELT® PP is a non-woven geotextile formed by polypropylene threads, interwoven by needling, without the need or application of chemical binders. It has excellent mechanical and hydraulic behavior. Nonwoven polypropylene geotextiles are used primarily for separation, filtration, and drainage applications. They are typically installed between different layers of soil or other materials to prevent them from mixing together and to improve drainage.

Advantages & Benefits

  • High resistance to static and dynamic piercing.
  • Prevents conflict or bonding between two different materials.
  • Long life expectancy.
  • High resistance to chemical and biological elements in the soil
  • It maintains the mechanical and hydraulic properties of the materials it separates intact.
  • Allows for adaptation to any type of geometry.
  • Protects waterproofing sheets from pressure and tensions caused by edges and sharp objects of the support.

Instruction for Use

Preparation of the substrate:
  • The surface of the base substrate must be resistant, uniform, compact and dry.
  • The singular points must also be prepared before starting the laying of the geotextile: chamfers or chamfers in meetings with vertical walls, reinforcements, joints and other singular points.
Laying the geotextile:
  • Once the ground or substrate has been levelled, the roll of DANOFELT PP is laid. The second roll is then laid, leaving a minimum overlap of 20 cm. Depending on the final application, it is recommended to fix the joint by stitching or stapling.
  • The materials should be poured without damaging the geotextile. In the same way, the spreading of the different layers should be carried out in such a way that the spreading and compacting equipment does not circulate at any time on the surface of the geotextile, and always in such a way that the direction of advance of the spreading machinery of the upper layer is carried out in such a way that it does not affect the overlapping of the geotextile layers.

Indications and Important Recommendations

  • It is UV resistant, so it can be left uncoated for a certain period of time without deterioration of its mechanical-hydraulic properties.
  • 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.
  • The circulation of machinery and construction vehicles over the geotextile is strictly forbidden in order to avoid mechanical damage or folds in the geotextile, which would impede the correct functioning for which it has been designed.
  • Store in a dry place.
  • Can be in contact with fresh concrete.
  • It can be used in systems with mechanical fixing, as the fibres do not cause mechanical problems in the process of installing the fixing to the substrate.
  • Special attention must be paid to the execution of the singular points, such as parapets (meetings with vertical and emergent elements), drains, expansion joints, etc.
  • It is recommended to preserve the material in its packaging and protected from the weather until use.
  • According to tests exposed in the achievement of the CE marking of this product, it has a minimum durability of 25 years, covered and installed in soils with a pH between 4 and 9 at a floor temperature <25ºC.
