Abstract:The Water Proofing System for underground culvert of NAJMAT project in UAE shall be of high performance and
properties to withstand complicated conditions,such as water resistance against sea water pressure of 10 m depth, hot weather
resistance,and chemical resistance of dilute acids, dilute alkalis,sulphates and chlorides etc. This paper introduces the
application of the new water proofing system mainly consist of PVC membrane and water stop belts in the project,and the
