THRISSUR: Geocell tarring, a solution to the collapse of roads caused by soil subsidence during rains, to be used in Kerala as well. This is a method of tarring the road after sealing it with high-density polypropylene (plastic) chambers. This method will be a relief for coastal roads and other roads where there is permanent waterlogging. Geocell tarring is widespread in European countries.
Road work using Geotextile (Geocell) for the first time in the state is progressing on the Kecheri Bypass on the Thrissur-Kuttippuram State Highway. It will also be used at Vizhinjam Shipyard.
Honeycomb-like geocell cells are stacked on the road and filled with a mixture of metal and M-sand (Wetmix Macadam). After it settles in the soil, tarring is done over it. Geo cells are laid after strengthening the soil by pounding it.
Geocell is being used for a 1.2 km road through the middle of the field on a total of 10 km road in Kecheri Bypass. This is a road where traffic is blocked during the rainy season. Geocell is brought from Maharashtra at a rate of Rs 650 per square meter. The cost of the road is 48.59 crores.
Retaining wall will also be strong
