DANOFET® PY is a non-woven geotextile formed by polyester threads, interwoven by needling, without the need or application of chemical binders. It has excellent mechanical and hydraulic behavior. Overall, nonwoven polyester geotextiles are an effective and versatile material for a wide range of civil engineering and construction applications, providing improved separation, filtration, and drainage applications.

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 PY is laid. The second roll is then laid, leaving a minimum overlap of 20cm. 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 does not affect the overlapping of the geotextile layers.
