As per the site visit & structural detailing vide structural drawing provided by DMRC we have concluded the rail track of DMRC for Phase-3
The cohesive weariness of concrete with the heterogeneous material
As the deficiency stated above concrete shows delaminated/non bonding behavior all across the Bolt pockets and any fasteners used, which is a basic property one can visualize with the property of concrete.
Consumption 2 cartridges of 600 ML each would be used in 1 joint. On approximation 1 km will have 35 such joints and around 70 cartridges of 600 ML Polyurea systems would be used
As the structure with above said detail is having leakage/seepage/dampness because of following reasons as observed
The leakage within the structure is continuous, less in summer season and highest in rainy season which is indicative of following
Surface Preparation-The area under leakage treatment has to be well repaired surface by mechanical or manual means (Sand Blasting/scarifying) to remove all loose lattinces, dirt,dust,corrosion,rust,formation of Ferrous oxides extra complete as per manufacturers specifications or instruction of Engineer In charge
