Sewage system Teheran

The Water Authorities required a fast curing surface coating system with high chemical resistance, fast working times, superior tensile strength, no cracking and stable features for the refurbishment of a 7 year old sewage tunnel. Lack of time and extreme

This 7 year old sewerage tunnel had badly degraded being fully exposed to sewer water with no substrate protection having been installed at the time of installation. Replacement was not an option. In order for the pipe to have any hope of lasting its intended design life it needed a long term protective coating solution capable of bridging cracks and remaining flexible to handle future substrate movements. In addition the lining solution had to exhibit high abrasion resistance, high elongation at break properties and excellent tensile strength to handle substrate movements. Despite the extreme operating environment the complete solution was installed from start to finish in 4 months and has been operating without any issues since 2010.
