Waterproofing of underground structures has a key role in operation of these kinds of structures below groundwater level.

Main activities of this team are:

  • Development of drainage and waterproofing methods
  • Technical support for selection of appropriate materials such as Geo-synthetic products, water sealing materials
  • Designing and construction of efficient drainage and waterproofing systems for underground structures (tunnels, metro stations, deep excavations, landfills, canal lining and underground facilities)

Waterproofing Materials Used:

  • Geosynthetics
    • GCL
    • Geomembrane (PVC, VLDPE, LLDPE, HDPE, …)
  • Cementitious Waterproofing
  • Injection Waterproofing systems
