Is the current tunnel construction, modular waterproof board (geotextile) is available?
We use the soil is a geotech cloth waterproof board
Geotextiles generally do not design applications in tunnel waterproofing. Because he can not meet the requirements of tunnel waterproofing
This is a new type of combination of anti-storage, drainage and drainage structure: the bottom of the polymer thermoplastic waterproof sheet, the surface of the sheet was plum-shaped hollow conical arrangement, the middle is unique by the two layers of staggered Composed of TDV three-dimensional geonet, the upper non-woven geotextile, the combination of new products in the use of the process to maintain a considerable thickness, load load increases, can provide a high conductivity.
