Testing of Geosynthetic Materials (Drainage Materials) for Railway EngineeringHow to apply for a report? What items need to be tested? We will conduct testing and evaluation in strict accordance with the standards. We can also provide personalized testing plans and reports according to your needs.

Drainage materials are the overall definition of a series of materials for various water facilities such as sewage discharge, environmental protection, and tap water. The quality of waterproof and drainage materials is a relatively important aspect. In order to strictly control the construction quality of railway tunnel waterproof engineering, it is necessary to strengthen the control of the quality of waterproof and drainage materials entering the construction site, and the quality inspection of ordinary waterproof boards is also particularly important. Classification of pipeline protection: waterproof casing, flexible waterproof casing, rigid waterproof casing, stainless steel waterproof casing valve connection: power transmission joint, expansion joint, expansion joint door valve series: duckbill valve, electric valve, automatic valve sewage treatment: water purification agent, decolorizing agent, ferrous chloride compensator series: universal corrugated compensator, internal pressure corrugated compensator inspection items: appearance quality, size and limit deviation, tensile performance, impermeability, tear strength Low temperature bending resistance, heating expansion, artificial climate aging, hot air aging, alkali resistance, puncture strength, combustion performance
