High-speed rail 2-type sliding layer to use two cloth a film, geotextile wool surface close to the concrete, but in the geotextile between the smooth and matte surface there is controversy, both sides of the geotextile is fluffy soft , A smooth side of some hard, hope to understand the master to answer the hairy side is smooth or matte surface? Thank you more
You do not call geotextile cloth, you called the permeable template cloth, geotextile cloth on both sides of the hair!
Hairy side is smooth, do when the hair surface paste concrete, on the film and then meet the smooth surface, that is, both sides of the hairy folder to the middle of the structure, or not play the role of sliding
