Geomembrane construction important surface poor base quality base quality directly affects the waterproof efficiency of plastic geomembrane plastic geomembrane as initial support (shotcrete, continuous wall) laying requires that the base surface should be very flat effortless and meet the ideal requirements according to engineering practice experience mention: Laying plastic geomembrane base should be flat without sharp objects base flatness should meet the D / L=1/6 ~ 1/10 requirements formula: D-- initial supporting base adjacent two convexes recess depth L-- distance between initial supporting base adjacent two convexes click ID to consult more questions
