Can the roof waterproof with geotextiles?
It is generally believed that the individual geotextile does not have the anti-seepage effect, the main assessment index is the permeability coefficient, the general geotextile coefficient is higher than the ordinary soil, about 0.01-0.001 look, but geotextiles and rubber, Asphalt, plastic will form a combination of impermeable composite, anti-seepage effect increased by 10 times, and asphalt, rubber combined into a waterproof
According to personal circumstances, but suggested to find professional personnel assessment.

The process needs to have a waterproof, leak-proof, anti-seepage function, the summer high temperature can be high temperature, anti-ultraviolet, cold winter to have anti-freeze-resistant low temperature, daily sunshine to have anti-aging and so on.
